# SITER Solar Project - Agent Documentation
|
||||
|
||||
This document provides technical reference for AI agents working on this project.
|
||||
|
||||
## Software Development Lifecycle (SDLC)
|
||||
|
||||
### Host System: Git and Docker ONLY
|
||||
|
||||
**All work must be done inside Docker containers.** The host system is ONLY for:
|
||||
|
||||
1. **Git operations** - commit, push, pull, branch, etc.
|
||||
2. **Docker operations** - build, run, exec, etc.
|
||||
|
||||
**Never run code, tests, or other tools directly on the host system.**
|
||||
|
||||
### Development Workflow
|
||||
|
||||
1. **Build Docker image:**
|
||||
```bash
|
||||
docker build -f Dockerfile.test -t siter-solar-test .
|
||||
```
|
||||
|
||||
2. **Run tests inside Docker:**
|
||||
```bash
|
||||
docker run --rm siter-solar-test
|
||||
```
|
||||
|
||||
3. **Run analysis inside Docker:**
|
||||
```bash
|
||||
docker run --rm -e NREL_API_KEY=your_key siter-solar-test /app/solar-analysis/siter-solar-analysis.sh --scenarios
|
||||
```
|
||||
|
||||
4. **Make atomic commits** using conventional commit format:
|
||||
- `feat:` - New feature
|
||||
- `fix:` - Bug fix
|
||||
- `docs:` - Documentation only
|
||||
- `test:` - Adding/updating tests
|
||||
- `refactor:` - Code refactoring
|
||||
- `chore:` - Maintenance tasks
|
||||
|
||||
### Code/Docs/Tests Synchronization
|
||||
|
||||
**Code, documentation, and tests MUST be kept in sync at all times.**
|
||||
|
||||
- When changing code, update tests and documentation in the same commit
|
||||
- When changing documentation, verify code still matches
|
||||
- When changing tests, ensure code passes new tests
|
||||
- Pre-commit hooks enforce this synchronization
|
||||
|
||||
## Privacy Requirements
|
||||
|
||||
**CRITICAL: This is a public repository. All private data must be removed.**
|
||||
|
||||
### What MUST NOT be committed:
|
||||
- Real addresses or locations (use "SITER" as placeholder)
|
||||
- Account numbers, contract IDs, or meter numbers
|
||||
- The `base-bill/` directory (contains personal billing data)
|
||||
- `.env` file (contains real coordinates and API keys)
|
||||
|
||||
### What should be committed:
|
||||
- `.env.example` - Template with placeholder values
|
||||
- All code and documentation with "SITER" as location identifier
|
||||
- SVG images and analysis scripts
|
||||
|
||||
### Location Data:
|
||||
- Use configurable environment variables: `SITER_LAT`, `SITER_LON`
|
||||
- Default to central Texas coordinates (30.44, -97.62)
|
||||
- Never commit specific addresses

||||

|
||||
## Running NREL Analysis
|
||||
|
||||
### Using Bash Script (Recommended)
|
||||
|
||||
Inside Docker:
|
||||
```bash
|
||||
# Basic analysis
|
||||
./siter-solar-analysis.sh
|
||||
|
||||
# With custom API key
|
||||
./siter-solar-analysis.sh -k YOUR_API_KEY
|
||||
|
||||
# Compare system sizes
|
||||
./siter-solar-analysis.sh --scenarios
|
||||
|
||||
# JSON output
|
||||
./siter-solar-analysis.sh --json
|
||||
|
||||
# Custom configuration
|
||||
./siter-solar-analysis.sh -p 20 -w 400 --lat 30.5 --lon -97.7
|
||||
```
|
||||
|
||||
### Python Scripts (DEPRECATED)
|
||||
|
||||
The Python scripts are kept for reference only. Use the bash script instead.
|
||||
|
||||
## Key Parameters
|
||||
|
||||
| Parameter | Value | Notes |
|
||||
|-----------|-------|-------|
|
||||
| System Capacity | 4.0 kW DC | 16 × 250W panels |
|
||||
| Array Type | Fixed Open Rack | Ground mount |
|
||||
| Tilt | 30° | Optimal for latitude |
|
||||
| Azimuth | 180° | South-facing |
|
||||
| Losses | 14% (default) | Can optimize to 8% |
|
||||
|
||||
## Base Power Contract Details
|
||||
|
||||
- **Energy Rate:** $0.085/kWh (fixed through Oct 2028)
|
||||
- **Solar Buyback:** $0.04/kWh (credits apply to entire bill)
|
||||
- **Subscription Fee:** $10/month
|
||||
|
||||
## ROI Calculation Method
|
||||
|
||||
1. Annual production from NREL PVWatts (kWh/year)
|
||||
2. Self-consumption: 60% × production × $0.085/kWh
|
||||
3. Grid export: 40% × production × $0.04/kWh
|
||||
4. Total annual value = self-consumption + export
|
||||
5. Payback = Total investment / annual value
|
||||
|
||||
## Testing
|
||||
|
||||
Run tests inside Docker:
|
||||
```bash
|
||||
docker build -f Dockerfile.test -t siter-solar-test .
|
||||
docker run --rm siter-solar-test
|
||||
```
|
||||
|
||||
## Updating the Analysis
|
||||
|
||||
1. Modify `siter-solar-analysis.sh` as needed
|
||||
2. Update tests in `tests/siter-solar-analysis.bats`
|
||||
3. Run tests to verify changes
|
||||
4. Update `v2-siter-solar-plan.md` with new estimates
|
||||
5. Commit all changes together in atomic commit

# Contributing to SITER Solar
|
||||
|
||||
Thank you for your interest in contributing to SITER Solar! This document provides guidelines and instructions for contributing.
|
||||
|
||||
## Code of Conduct
|
||||
|
||||
By participating in this project, you agree to maintain a respectful and inclusive environment for all contributors.
|
||||
|
||||
## Development Environment
|
||||
|
||||
### Prerequisites
|
||||
|
||||
- Docker (required for all development)
|
||||
- Git
|
||||
|
||||
### Important: Docker-Only Development
|
||||
|
||||
**All development work must be done inside Docker containers.** Only `git` and `docker` commands are allowed on the host system. This ensures:
|
||||
|
||||
- Consistent development environment
|
||||
- Reproducible builds
|
||||
- Isolation from host system
|
||||
|
||||
### Setting Up

|
||||
```bash
|
||||
git clone <repository-url>
|
||||
cd SITER-Solar
|
||||
```
|
||||
|
||||
2. Build the test environment:
|
||||
```bash
|
||||
docker build -f Dockerfile.test -t siter-solar-test .
|
||||
```
|
||||
|
||||
3. Run tests:
|
||||
```bash
|
||||
docker run --rm siter-solar-test
|
||||
```
|
||||
|
||||
4. Run the analysis script:

```
|
||||
|
||||
### Pre-commit Hooks
|
||||
|
||||
The repository includes pre-commit hooks that enforce:
|
||||
|
||||
1. **No private data** - Scans for addresses, phone numbers, contract numbers
|
||||
2. **Shellcheck** - All shell scripts must pass shellcheck
|
||||
3. **Tests** - All tests must pass
|
||||
4. **Conventional commits** - Commit messages must follow the format
|
||||
|
||||
### Testing
|
||||
|
||||
We use BATS (Bash Automated Testing System) for testing.
|
||||
|
||||
#### Running Tests
|
||||
|
||||
```bash
|
||||
# In Docker
|
||||
docker run --rm siter-solar-test
|
||||
|
||||
# Run specific test
|
||||
docker run --rm --entrypoint="" siter-solar-test bats /app/solar-analysis/tests/siter-solar-analysis.bats -f "help option"
|
||||
```
|
||||
|
||||
#### Writing Tests
|
||||
|
||||
- Place tests in `solar-analysis/tests/`
|
||||
- Use descriptive test names
|
||||
- Tests should be independent and idempotent
|
||||
- Mock external API calls when possible
|
||||
- Test edge cases and error conditions
|
||||
|
||||
### Code Style
|
||||
|
||||
#### Shell Scripts
|
||||
|
||||
- Use `#!/usr/bin/env bash` shebang
|
||||
- Enable strict mode: `set -euo pipefail`
|
||||
- Use `readonly` for constants
|
||||
- Add shellcheck directives where needed
|
||||
- Document functions with comments
|
||||
|
||||
#### Documentation
|
||||
|
||||
- Update README.md for user-facing changes
|
||||
- Update AGENTS.md for AI assistant context
|
||||
- Keep documentation synchronized with code
|
||||
|
||||
## Privacy and Security
|
||||
|
||||
### Private Data
|
||||
|
||||
**Never commit private data to the repository.** This includes:
|
||||
|
||||
- Real addresses
|
||||
- Contract numbers
|
||||
- Meter numbers
|
||||
- API keys
|
||||
- Personal information
|
||||
|
||||
The `.gitignore` file excludes:
|
||||
- `base-bill/` - Contains personal billing data
|
||||
- `.env` - Contains API keys and location data
|
||||
- Any files matching `*SITER*` patterns
|
||||
|
||||
### API Keys
|
||||
|
||||
- Never commit API keys
|
||||
- Use environment variables only
|
||||
- API keys via CLI arguments are prohibited (security - process list visibility)
|
||||
- Use `.env.example` as a template
|
||||
|
||||

||||
incorporate. Many developers of free software are heartened and
|
||||
encouraged by the resulting cooperation. However, in the case of
|
||||
software used on network servers, this result may fail to come about.
|
||||
The GNU General Public License permits making a modified version and
|
||||
letting the public access it on a server without ever releasing its
|
||||
source code to the public.
|
||||
A secondary benefit of defending all users' freedom is that improvements made in alternate versions of the program, if they receive widespread use, become available for other developers to incorporate. Many developers of free software are heartened and encouraged by the resulting cooperation. However, in the case of software used on network servers, this result may fail to come about. The GNU General Public License permits making a modified version and letting the public access it on a server without ever releasing its source code to the public.
|
||||
|
||||
The GNU Affero General Public License is designed specifically to
|
||||
ensure that, in such cases, the modified source code becomes available
|
||||
to the community. It requires the operator of a network server to
|
||||
provide the source code of the modified version running there to the
|
||||
users of that server. Therefore, public use of a modified version, on
|
||||
a publicly accessible server, gives the public access to the source
|
||||
code of the modified version.

feature that (1) displays an appropriate copyright notice, and (2)

form of a work.
|

A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language.

|
||||
The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it.

the source code needed to generate, install, and (for an executable

work) run the object code and to modify the work, including scripts to
|

control those activities. However, it does not include the work's

System Libraries, or general-purpose tools or generally available free
|

programs which are used unmodified in performing those activities but

which are not part of the work. For example, Corresponding Source

includes interface definition files associated with source files for

linked subprograms that the work is specifically designed to require,

such as by intimate data communication or control flow between those

|
||||
|
||||
2. Basic Permissions.
|
||||
|
||||
All rights granted under this License are granted for the term of
|
||||
copyright on the Program, and are irrevocable provided the stated
|
||||
conditions are met. This License explicitly affirms your unlimited
|
||||
permission to run the unmodified Program. The output from running a
|
||||
covered work is covered by this License only if the output, given its
|
||||
content, constitutes a covered work. This License acknowledges your
|
||||
rights of fair use or other equivalent, as provided by copyright law.
|
||||
|
||||
You may make, run and propagate covered works that you do not
|
||||
convey, without conditions so long as your license otherwise remains
|
||||
in force. You may convey covered works to others for the sole purpose
|
||||
of having them make modifications exclusively for you, or provide you
|
||||
with facilities for running those works, provided that you comply with
|
||||
the terms of this License in conveying all material for which you do
|
||||
not control copyright. Those thus making or running the covered works
|
||||
for you must do so exclusively on your behalf, under your direction
|
||||
and control, on terms that prohibit them from making any copies of
|
||||
your copyrighted material outside their relationship with you.
|
||||
|
||||
Conveying under any other circumstances is permitted solely under
|
||||
the conditions stated below. Sublicensing is not allowed; section 10
|
||||
makes it unnecessary.
|
||||
|
||||
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
|
||||
|
||||
No covered work shall be deemed part of an effective technological
|
||||
measure under any applicable law fulfilling obligations under article
|
||||
11 of the WIPO copyright treaty adopted on 20 December 1996, or
|
||||
similar laws prohibiting or restricting circumvention of such
|
||||
measures.
|
||||
|
||||
When you convey a covered work, you waive any legal power to forbid
|
||||
circumvention of technological measures to the extent such circumvention
|
||||
is effected by exercising rights under this License with respect to the
|
||||
covered work, and you disclaim any intention to limit operation of
|
||||
the work or modification of the work as a means of enforcing, against
|
||||
the work's users, your or third parties' legal rights to forbid
|
||||
circumvention of technological measures.
|
||||
|
||||
4. Conveying Verbatim Copies.
|
||||
|
||||
You may convey verbatim copies of the Program's source code as you
|
||||
receive it, in any medium, provided that you conspicuously and
|
||||
appropriately publish on each copy an appropriate copyright notice;
|
||||
keep intact all notices stating that this License and any
|
||||
non-permissive terms added in accord with section 7 apply to the code;
|
||||
keep intact all notices of the absence of any warranty; and give all
|
||||
recipients a copy of this License along with the Program.
|
||||
|
||||
You may charge any price or no price for each copy that you convey,
|
||||
and you may offer support or warranty protection for a fee.
|
||||
|
||||
5. Conveying Modified Source Versions.
|
||||
|
||||
You may convey a work based on the Program, or the modifications to
|
||||
produce it from the Program, in the form of source code under the
|
||||
terms of section 4, provided that you also meet all of these conditions:
|
||||
|
||||
a) The work must carry prominent notices stating that you modified
|
||||
it, and giving a relevant date.
|
||||
|
||||
b) The work must carry prominent notices stating that it is
|
||||
released under this License and any conditions added under section
|
||||
7. This requirement modifies the requirement in section 4 to
|
||||
"keep intact all notices".
|
||||
|
||||
c) You must license the entire work, as a whole, under this
|
||||
License to anyone who comes into possession of a copy. This
|
||||
License will therefore apply, along with any applicable section 7
|
||||
additional terms, to the whole of the work, and all its parts,
|
||||
regardless of how they are packaged. This License gives no
|
||||
permission to license the work in any other way, but it does not
|
||||
invalidate such permission if you have separately received it.
|
||||
|
||||
d) If the work has interactive user interfaces, each must display
|
||||
Appropriate Legal Notices; however, if the Program has interactive
|
||||
interfaces that do not display Appropriate Legal Notices, your
|
||||
work need not make them do so.
|
||||
|
||||
A compilation of a covered work with other separate and independent
|
||||
works, which are not by their nature extensions of the covered work,
|
||||
and which are not combined with it such as to form a larger program,
|
||||
in or on a volume of a storage or distribution medium, is called an
|
||||
"aggregate" if the compilation and its resulting copyright are not
|
||||
used to limit the access or legal rights of the compilation's users
|
||||
beyond what the individual works permit. Inclusion of a covered work
|
||||
in an aggregate does not cause this License to apply to the other
|
||||
parts of the aggregate.
|
||||
|
||||
6. Conveying Non-Source Forms.
|
||||
|
||||
You may convey a covered work in object code form under the terms
|
||||
of sections 4 and 5, provided that you also convey the
|
||||
machine-readable Corresponding Source under the terms of this License,
|
||||
in one of these ways:
|
||||
|
||||
a) Convey the object code in, or embodied in, a physical product
|
||||
(including a physical distribution medium), accompanied by the
|
||||
Corresponding Source fixed on a durable physical medium
|
||||
customarily used for software interchange.
|
||||
|
||||
b) Convey the object code in, or embodied in, a physical product
|
||||
(including a physical distribution medium), accompanied by a
|
||||
written offer, valid for at least three years and valid for as
|
||||
long as you offer spare parts or customer support for that product
|
||||
model, to give anyone who possesses the object code either (1) a
|
||||
copy of the Corresponding Source for all the software in the
|
||||
product that is covered by this License, on a durable physical
|
||||
medium customarily used for software interchange, for a price no
|
||||
more than your reasonable cost of physically performing this
|
||||
conveying of source, or (2) access to copy the
|
||||
Corresponding Source from a network server at no charge.
|
||||
|
||||
c) Convey individual copies of the object code with a copy of the
|
||||
written offer to provide the Corresponding Source. This
|
||||
alternative is allowed only occasionally and noncommercialally, and
|
||||
only if you received the object code with such an offer, in accord
|
||||
with subsection 6b.
|
||||
|
||||
d) Convey the object code by offering access from a designated
|
||||
place (gratis or for a charge), and offer equivalent access to the
|
||||
Corresponding Source in the same way through the same place at no
|
||||
further charge. You need not require recipients to copy the
|
||||
Corresponding Source along with the object code. If the place to
|
||||
copy the object code is a network server, the Corresponding Source
|
||||
may be on a different server (operated by you or a third party)
|
||||
that supports equivalent copying facilities, provided you maintain
|
||||
clear directions next to the object code saying where to find the
|
||||
Corresponding Source. Regardless of what server hosts the
|
||||
Corresponding Source, you remain obligated to ensure that it is
|
||||
available for as long as needed to satisfy these requirements.
|
||||
|
||||
e) Convey the object code using peer-to-peer transmission, provided
|
||||
you inform other peers where the object code and Corresponding
|
||||
Source of the work are being offered to the general public at no
|
||||
charge under subsection 6d.
|
||||
|
||||
A separable portion of the object code, whose source code is excluded
|
||||
from the Corresponding Source as a System Library, need not be
|
||||
included in conveying the object code work.
|
||||
|
||||
A "User Product" is either (1) a "consumer product", which means any
|
||||
tangible personal property which is normally used for personal, family,
|
||||
or household purposes, or (2) anything designed or sold for incorporation
|
||||
into a dwelling. In determining whether a product is a consumer product,
|
||||
doubtful cases shall be resolved in favor of coverage. For a particular
|
||||
product received by a particular user, "normally used" refers to a
|
||||
typical or common use of that class of product, regardless of the status
|
||||
of the particular user or of the way in which the particular user
|
||||
actually uses, or expects or is expected to use, the product. A product
|
||||
is a consumer product regardless of whether the product has substantial
|
||||
commercial, industrial or non-consumer uses, unless such uses represent
|
||||
the only significant mode of use of the product.
|
||||
|
||||
"Installation Information" for a User Product means any methods,
|
||||
procedures, authorization keys, or other information required to install
|
||||
and execute modified versions of a covered work in that User Product from
|
||||
a modified version of its Corresponding Source. The information must
|
||||
suffice to ensure that the continued functioning of the modified object
|
||||
code is in no case prevented or interfered with solely because
|
||||
modification has been made.
|
||||
|
||||
If you convey an object code work under this section in, or with, or
|
||||
specifically for use in a User Product, and the conveying occurs as
|
||||
part of a transaction in which the right to possession and use of the
|
||||
User Product is transferred to the recipient in perpetuity or for a
|
||||
fixed term (regardless of how the transaction is characterized), the
|
||||
Corresponding Source conveyed under this section must be accompanied
|
||||
by the Installation Information. But this requirement does not apply
|
||||
if neither you nor any third party retains the ability to install
|
||||
modified object code on the User Product (for example, the work has
|
||||
been installed in ROM).
|
||||
|
||||
The requirement to provide Installation Information does not include
|
||||
a requirement to continue to provide support service, warranty, or
|
||||
updates for a work that has been modified or installed by the recipient,
|
||||
or for the User Product in which it has been modified or installed.
|
||||
Access to a network may be denied when the modification itself
|
||||
materially and adversely affects the operation of the network or
|
||||
violates the rules and protocols for communication across the network.
|
||||
|
||||
Corresponding Source conveyed, and Installation Information provided,
|
||||
in accord with this section must be in a format that is publicly
|
||||
documented (and with an implementation available to the public in
|
||||
source code form), and must require no special password or key for
|
||||
unpacking, reading or copying.
|
||||
|
||||
7. Additional Terms.
|
||||
|
||||
"Additional permissions" are terms that supplement the terms of this
|
||||
License by making exceptions from one or more of its conditions.
|
||||
Additional permissions that are applicable to the entire Program shall
|
||||
be treated as though they were included in this License, to the extent
|
||||
that they are valid under applicable law. If additional permissions
|
||||
apply only to part of the Program, that part may be used separately
|
||||
under those permissions, but the entire Program remains governed by
|
||||
this License without regard to the additional permissions.
|
||||
|
||||
When you convey a copy of a covered work, you may at your option
|
||||
remove any additional permissions from that copy, or from any part of
|
||||
it. (Additional permissions may be written to require their own
|
||||
removal in certain cases when you modify the work.) You may place
|
||||
additional permissions on material, added by you to a covered work,
|
||||
for which you have or can give appropriate copyright permission.
|
||||
|
||||
Notwithstanding any other provision of this License, for material you
|
||||
add to a covered work, you may (if authorized by the copyright holders
|
||||
of that material) supplement the terms of this License with terms:
|
||||
|
||||
a) Disclaiming warranty or limiting liability differently from the
|
||||
terms of sections 15 and 16 of this License; or
|
||||
|
||||
b) Requiring preservation of specified reasonable legal notices or
|
||||
author attributions in that material or in the Appropriate Legal
|
||||
Notices displayed by works containing it; or
|
||||
|
||||
c) Prohibiting misrepresentation of the origin of that material, or
|
||||
requiring that modified versions of such material be marked in
|
||||
reasonable ways as different from the original version; or
|
||||
|
||||
d) Limiting the use for publicity purposes of names of licensors or
|
||||
authors of the material; or
|
||||
|
||||
e) Declining to grant rights under trademark law for use of some
|
||||
trade names, trademarks, or service marks; or
|
||||
|
||||
f) Requiring indemnification of licensors and authors of that
|
||||
material by anyone who conveys the material (or modified versions
|
||||
of it) with contractual assumptions of liability to the recipient,
|
||||
for any liability that these contractual assumptions directly
|
||||
impose on those licensors and authors.
|
||||
|
||||
All other non-permissive additional terms are considered "further
|
||||
restrictions" within the meaning of section 10. If the Program as you
|
||||
received it, or any part of it, contains a notice stating that it is
|
||||
governed by this License along with a term that is a further
|
||||
restriction, you may remove that term. If a license document contains
|
||||
a further restriction but permits relicensing or conveying under this
|
||||
License, you may add to a covered work material governed by the terms
|
||||
of that license document, provided that the further restriction does
|
||||
not survive such relicensing or conveying.
|
||||
|
||||
If you add terms to a covered work in accord with this section, you
|
||||
must place, in the relevant source files, a statement of the
|
||||
additional terms that apply to those files, or a notice indicating
|
||||
where to find the applicable terms.
|
||||
|
||||
Additional terms, permissive or non-permissive, may be stated in the
|
||||
form of a separately written license, or stated as exceptions;
|
||||
the above requirements apply either way.
|
||||
|
||||
8. Termination.
|
||||
|
||||
You may not propagate or modify a covered work except as expressly
|
||||
provided under this License. Any attempt otherwise to propagate or
|
||||
modify it is void, and will automatically terminate your rights under
|
||||
this License (including any patent licenses granted under the third
|
||||
paragraph of section 11).
|
||||
|
||||
However, if you cease all violation of this License, then your
|
||||
license from a particular copyright holder is reinstated (a)
|
||||
provisionally, unless and until the copyright holder explicitly and
|
||||
finally terminates your license, and (b) permanently, if the copyright
|
||||
holder fails to notify you of the violation by some reasonable means
|
||||
prior to 60 days after the cessation.
|
||||
|
||||
Moreover, your license from a particular copyright holder is
|
||||
reinstated permanently if the copyright holder notifies you of the
|
||||
violation by some reasonable means, this is the first time you have
|
||||
received notice of violation of this License (from that copyright
|
||||
holder) since you received the Program, and you cure the violation
|
||||
prior to 30 days after your receipt of the notice.
|
||||
|
||||
Termination of your rights under this section does not terminate
|
||||
the licenses of parties who have received copies or rights from you
|
||||
under this License. If your rights have been terminated and not
|
||||
permanently reinstated, you do not qualify to receive new licenses
|
||||
for the same material under section 10.
|
||||
|
||||
9. Acceptance Not Required for Having Copies.
|
||||
|
||||
You are not required to accept this License in order to receive or
|
||||
run a copy of the Program. Ancillary propagation of a covered work
|
||||
occurring solely as a consequence of using peer-to-peer transmission
|
||||
to receive a copy likewise does not require acceptance. However,
|
||||
nothing other than this License grants you permission to propagate
|
||||
or modify any covered work. These actions infringe copyright if you
|
||||
do not accept this License. Therefore, by modifying or propagating
|
||||
a covered work, you indicate your acceptance of this License to do so.
|
||||
|
||||
10. Automatic Licensing of Downstream Recipients.
|
||||
|
||||
Each time you convey a covered work, the recipient automatically
|
||||
receives a license from the original licensors, to run, modify and
|
||||
propagate that work, subject to this License. You are not responsible
|
||||
for enforcing compliance by third parties with this License.
|
||||
|
||||
An "entity transaction" is a transaction transferring control of an
|
||||
organization, or substantially all assets of one, or subdividing an
|
||||
organization, or merging organizations. If propagation of a covered
|
||||
work results from an entity transaction, each party to that transaction
|
||||
who receives a copy of the work also receives whatever licenses to the
|
||||
work the party's predecessor in interest had or could give under the
|
||||
previous paragraph, plus a right to possession of the Corresponding
|
||||
Source of the work from the predecessor in interest, if the predecessor
|
||||
has it or can get it with reasonable efforts.
|
||||
|
||||
You may not impose any further restrictions on the exercise of the
|
||||
rights granted or affirmed under this License. For example, you may
|
||||
not impose a license fee, royalty, or other charge for exercise of
|
||||
rights granted under this License, and you may not initiate litigation
|
||||
(including a cross-claim or counterclaim in a lawsuit) alleging that
|
||||
any patent claim is infringed by making, using, selling, offering for
|
||||
sale, or importing the Program or any portion of it.
|
||||
|
||||
11. Patents.
|
||||
|
||||
A "contributor" is a copyright holder who authorizes use under this
|
||||
License of the Program or a work on which the Program is based. The
|
||||
work thus licensed is called the contributor's "contributor version".
|
||||
|
||||
A contributor's "essential patent claims" are all patent claims
|
||||
owned or controlled by the contributor, whether already acquired or
|
||||
hereafter acquired, that would be infringed by some manner, permitted
|
||||
by this License, of making, using, or selling its contributor version,
|
||||
but do not include claims that would be infringed only as a consequence
|
||||
of further modification of the contributor version. For purposes of
|
||||
this definition, "control" includes the right to grant patent
|
||||
sublicenses in a manner consistent with the requirements of this
|
||||
License.
|
||||
|
||||
Each contributor grants you a non-exclusive, worldwide, royalty-free
|
||||
patent license under the contributor's essential patent claims, to
|
||||
make, use, sell, offer for sale, import and otherwise run, modify and
|
||||
propagate the contents of its contributor version.
|
||||
|
||||
In the following three paragraphs, a "patent license" is any express
|
||||
agreement or commitment, however denominated, not to enforce a patent
|
||||
(such as an express permission to practice a patent or covenant not
|
||||
to sue for patent infringement). To "grant" such a patent license to
|
||||
a party means to make such an agreement or commitment not to enforce
|
||||
a patent against the party.
|
||||
|
||||
If you convey a covered work, knowingly relying on a patent license,
|
||||
and the Corresponding Source of the work is not available for anyone
|
||||
to copy, free of charge and under the terms of this License, through
|
||||
a publicly available network server or other readily accessible means,
|
||||
then you must either (1) cause the Corresponding Source to be so
|
||||
available, or (2) arrange to deprive yourself of the benefit of the
|
||||
patent license for this particular work, or (3) arrange, in a manner
|
||||
consistent with the requirements of this License, to extend the patent
|
||||
license to downstream recipients. "Knowingly relying" means you have
|
||||
actual knowledge that, but for the patent license, your conveying the
|
||||
covered work in a country, or your recipient's use of the covered work
|
||||
in a country, would infringe one or more identifiable patents in that
|
||||
country that you have reason to believe are valid.
|
||||
|
||||
If, pursuant to or in connection with a single transaction or
|
||||
arrangement, you convey, or propagate by procuring conveyance of, a
|
||||
covered work, and grant a patent license to some of the parties
|
||||
receiving the covered work authorizing them to use, propagate, modify
|
||||
or convey a specific copy of the covered work, then the patent license
|
||||
you grant is automatically extended to all recipients of the covered
|
||||
work and works based on it.
|
||||
|
||||
A patent license is "discriminatory" if it does not include within
|
||||
the scope of its coverage, prohibits the exercise of, or is
|
||||
conditioned on the non-exercise of one or more of the rights that are
|
||||
specifically granted under this License. You may not convey a covered
|
||||
work if you are a party to an arrangement with a third party that is
|
||||
in the business of distributing software, under which you make payment
|
||||
to the third party based on the extent of your activity of conveying
|
||||
the work, and under which the third party grants, to any of the
|
||||
parties who would receive the covered work from you, a discriminatory
|
||||
patent license (a) in connection with copies of the covered work
|
||||
conveyed by you (or copies made from those copies), or (b) primarily
|
||||
for and in connection with specific products or compilations that
|
||||
contain the covered work, unless you entered into that arrangement,
|
||||
or that patent license was granted, prior to 28 March 2007.
|
||||
|
||||
Nothing in this License shall be construed as excluding or limiting
|
||||
any implied license or other defenses to infringement that may
|
||||
otherwise be available to you under applicable patent law.
|
||||
|
||||
12. No Surrender of Others' Freedom.
|
||||
|
||||
If conditions are imposed on you (whether by court order, agreement
|
||||
or otherwise) that contradict the conditions of this License, they do
|
||||
not excuse you from the conditions of this License. If you cannot
|
||||
convey a covered work so as to satisfy simultaneously your obligations
|
||||
under this License and any other pertinent obligations, then as a
|
||||
consequence you may not convey it at all. For example, if you agree
|
||||
to terms that obligate you to collect a royalty for further conveying
|
||||
from those to whom you convey the Program, the only way you could
|
||||
satisfy both those terms and this License would be to refrain entirely
|
||||
from conveying the Program.
|
||||
|
||||
13. Remote Network Interaction; Use with the GNU General Public License.
|
||||
|
||||
Notwithstanding any other provision of this License, if you modify
|
||||
the Program, your modified version must prominently offer all users
|
||||
interacting with it remotely through a computer network (if your
|
||||
version supports such interaction) an opportunity to receive the
|
||||
Corresponding Source of your version by providing access to the
|
||||
Corresponding Source from a network server at no charge, through some
|
||||
standard or customary means of facilitating copying of software. This
|
||||
Corresponding Source shall include the Corresponding Source for any
|
||||
work covered by version 3 of the GNU General Public License that is
|
||||
incorporated pursuant to the following paragraph.
|
||||
|
||||
Notwithstanding any other provision of this License, you have
|
||||
permission to link or combine any covered work with a work licensed
|
||||
under version 3 of the GNU General Public License into a single
|
||||
combined work, and to convey the resulting work. The terms of this
|
||||
License will continue to apply to the part which is the covered work,
|
||||
but the work with which it is combined will remain governed by version
|
||||
3 of the GNU General Public License.
|
||||
|
||||
14. Revised Versions of this License.
|
||||
|
||||
The Free Software Foundation may publish revised and/or new versions
|
||||
of the GNU Affero General Public License from time to time. Such new
|
||||
versions will be similar in spirit to the present version, but may
|
||||
differ in detail to address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the
|
||||
Program specifies that a certain numbered version of the GNU Affero
|
||||
General Public License "or any later version" applies to it, you have
|
||||
the option of following the terms and conditions either of that numbered
|
||||
version or of any later version published by the Free Software
|
||||
Foundation. If the Program does not specify a version number of the
|
||||
GNU Affero General Public License, you may choose any version ever
|
||||
published by the Free Software Foundation.
|
||||
|
||||
If the Program specifies that a proxy can decide which future versions
|
||||
of the GNU Affero General Public License can be used, that proxy's
|
||||
public statement of acceptance of a version permanently authorizes you
|
||||
to choose that version for the Program.
|
||||
|
||||
Later license versions may give you additional or different
|
||||
permissions. However, no additional obligations are imposed on any
|
||||
author or copyright holder as a result of your choosing to follow a
|
||||
later version.
|
||||
|
||||
15. Disclaimer of Warranty.
|
||||
|
||||
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
|
||||
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
|
||||
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
|
||||
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
|
||||
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
||||
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
|
||||
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
|
||||
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
||||
|
||||
16. Limitation of Liability.
|
||||
|
||||
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
|
||||
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
|
||||
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
|
||||
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
|
||||
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
|
||||
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
|
||||
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
|
||||
SUCH DAMAGES.
|
||||
|
||||
17. Interpretation of Sections 15 and 16.
|
||||
|
||||
If the disclaimer of warranty and limitation of liability provided
|
||||
above cannot be given local legal effect according to their terms,
|
||||
reviewing courts shall apply local law that most closely approximates
|
||||
an absolute waiver of all civil liability in connection with the
|
||||
Program, unless a warranty or assumption of liability accompanies a
|
||||
copy of the Program in return for a fee.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source.
|
||||
|
||||
The Corresponding Source for a work in source code form is that same work.
|
||||
|
||||
2. Basic Permissions.
|
||||
All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.
|
||||
|
||||
You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you.
|
||||
|
||||
Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
|
||||
|
||||
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
|
||||
No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.
|
||||
|
||||
When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.
|
||||
|
||||
4. Conveying Verbatim Copies.
|
||||
You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program.
|
||||
|
||||
You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.
|
||||
|
||||
5. Conveying Modified Source Versions.
|
||||
You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:
|
||||
|
||||
a) The work must carry prominent notices stating that you modified it, and giving a relevant date.
|
||||
|
||||
b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices".
|
||||
|
||||
c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.
|
||||
|
||||
d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.
|
||||
|
||||
A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate.
|
||||
|
||||
6. Conveying Non-Source Forms.
|
||||
You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:
|
||||
|
||||
a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange.
|
||||
|
||||
b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge.
|
||||
|
||||
c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b.
|
||||
|
||||
d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.
|
||||
|
||||
e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d.
|
||||
|
||||
A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work.
|
||||
|
||||
A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product.
|
||||
|
||||
"Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made.
|
||||
|
||||
If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM).
|
||||
|
||||
The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network.
|
||||
|
||||
Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying.
|
||||
|
||||
7. Additional Terms.
|
||||
"Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions.
|
||||
|
||||
When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission.
|
||||
|
||||
Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms:
|
||||
|
||||
a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or
|
||||
|
||||
b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or
|
||||
|
||||
c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or
|
||||
|
||||
d) Limiting the use for publicity purposes of names of licensors or authors of the material; or
|
||||
|
||||
e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or
|
||||
|
||||
f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors.
|
||||
|
||||
All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying.
|
||||
|
||||
If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms.
|
||||
|
||||
Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way.
|
||||
|
||||
8. Termination.
|
||||
|
||||
You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11).
|
||||
|
||||
However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.
|
||||
|
||||
Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.
|
||||
|
||||
Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10.
|
||||
|
||||
9. Acceptance Not Required for Having Copies.
|
||||
|
||||
You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so.
|
||||
|
||||
10. Automatic Licensing of Downstream Recipients.
|
||||
|
||||
Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License.
|
||||
|
||||
An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts.
|
||||
|
||||
You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it.
|
||||
|
||||
11. Patents.
|
||||
|
||||
A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version".
|
||||
|
||||
A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License.
|
||||
|
||||
Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version.
|
||||
|
||||
In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party.
|
||||
|
||||
If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent
|
||||
license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid.
|
||||
|
||||
If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it.
|
||||
|
||||
A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007.
|
||||
|
||||
Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law.
|
||||
|
||||
12. No Surrender of Others' Freedom.
|
||||
|
||||
If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may
|
||||
not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.
|
||||
|
||||
13. Remote Network Interaction; Use with the GNU General Public License.
|
||||
|
||||
Notwithstanding any other provision of this License, if you modify the Program, your modified version must prominently offer all users interacting with it remotely through a computer network (if your version supports such interaction) an opportunity to receive the Corresponding Source of your version by providing access to the Corresponding Source from a network server at no charge, through some standard or customary means of facilitating copying of software. This Corresponding Source shall include the Corresponding Source for any work covered by version 3 of the GNU General Public License that is incorporated pursuant to the following paragraph.
|
||||
|
||||
Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the work with which it is combined will remain governed by version 3 of the GNU General Public License.
|
||||
|
||||
14. Revised Versions of this License.
|
||||
|
||||
The Free Software Foundation may publish revised and/or new versions of the GNU Affero General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU Affero General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU Affero General Public License, you may choose any version ever published by the Free Software Foundation.
|
||||
|
||||
If the Program specifies that a proxy can decide which future versions of the GNU Affero General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program.
|
||||
|
||||
Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version.
|
||||
|
||||
15. Disclaimer of Warranty.
|
||||
|
||||
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
||||
|
||||
16. Limitation of Liability.
|
||||
|
||||
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
|
||||
|
||||
17. Interpretation of Sections 15 and 16.
|
||||
|
||||
If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
How to Apply These Terms to Your New Programs
|
||||
|
||||
If you develop a new program, and you want it to be of the greatest
|
||||
possible use to the public, the best way to achieve this is to make it
|
||||
free software which everyone can redistribute and change under these terms.

|
||||
|
||||
To do so, attach the following notices to the program. It is safest
|
||||
to attach them to the start of each source file to most effectively
|
||||
state the exclusion of warranty; and each file should have at least
|
||||
the "copyright" line and a pointer to where the full notice is found.

## Key Parameters
|
||||
|
||||
| Parameter | Value | Notes |
|
||||
|-----------|-------|-------|
|
||||
| System Capacity | 4.0 kW DC | 16 × 250W panels |
|
||||
| Array Type | Fixed Open Rack | Ground mount |
|
||||
| Tilt | 30° | Optimal for latitude |
|
||||
| Azimuth | 180° | South-facing |
|
||||
| Losses | 14% (default) | Can optimize to 8% |
|
||||
|
||||
## Financial Model
|
||||
|
||||
The analysis uses the following assumptions:
|
||||
|
||||
- **Self-consumption:** 60% of production (avoids $0.085/kWh)
|
||||
- **Grid export:** 40% of production (credits $0.04/kWh)
|
||||
- **Base Power contract:** Fixed rate through Oct 2028
|
||||
- **Solar buyback:** Credits apply to entire bill
|
||||
|
||||
### ROI Calculation
|
||||
|
||||
1. Annual production from NREL PVWatts (kWh/year)
|
||||
2. Self-consumption value: 60% × production × $0.085/kWh
|
||||
3. Export value: 40% × production × $0.04/kWh
|
||||
4. Total annual value = self-consumption + export
|
||||
5. Payback = Total investment / annual value
|
||||
|
||||
## NREL API
|
||||

# SITER Solar Installation Project
|
||||
## 2026 Renewable Energy Initiative - v2 Analysis
|
||||
|
||||
---
|
||||
|
||||
## Executive Summary
|
||||
|
||||
This document outlines a solar energy installation project for SITER, designed to offset a portion of monthly electricity costs through solar generation. The system will utilize 16 solar panels across 8 custom-built ground-mount racks, paired with a Sol-Ark 5K hybrid inverter that integrates with the existing Base Power battery backup system.
|
||||
|
||||
**Total Project Investment:** $4,100.00
|
||||
**Estimated ROI Period:** 9.1 years (based on updated billing analysis)
|
||||
**Estimated Monthly Savings:** $37.61 (14.2% bill offset)
|
||||
|
||||
**Existing Infrastructure:** SITER currently operates with a Base Power battery backup system and automatic transfer switch (ATS), installed in 2025, providing resilience and a fixed energy rate of **$0.085/kWh** through a 3-year contract (Oct 2025 - Oct 2028).
|
||||
|
||||
**Updated Billing Data (15 months):** Average monthly consumption of 1,885 kWh (~22,600 kWh/year) at average effective rate of $0.140/kWh.
|
||||
|
||||
**NREL PVWatts Analysis:** Based on location data for SITER, a 16-panel system (4.0 kW DC with 250W panels) is projected to produce ~6,000 kWh/year, offsetting approximately 14% of current consumption.

## Project Overview
|
||||
|
||||
### Objectives
|
||||
|
||||
- Reduce monthly electricity expenses through solar generation (~14% offset with current panels)
|
||||
- Integrate with existing Base Power battery backup infrastructure
|
||||
- Leverage Base Power's 4¢/kWh solar buyback program for excess production
|
||||
- Complete installation with minimal upfront capital expenditure
|
||||
- Achieve positive ROI within 10 years while gaining energy resilience
|
||||
|
||||
### Scope
|
||||
|
||||
| Component | Quantity | Description |
|
||||
|-----------|----------|-------------|
|
||||
| Solar Panels | 16 | Existing inventory (250W each) |
|
||||
| Ground-Mount Racks | 8 | Custom steel construction |
|
||||
| Inverter | 1 | Sol-Ark 5K Hybrid |
|
||||
| Wiring & Connectors | TBD | To be determined based on site layout |
|
||||
|
||||
### Current Status
|
||||
|
||||
- **Phase:** Initial procurement and rack construction
|
||||
- **Spend to Date:** $360.95 (first solar rack completed)
|
||||
- **Next Milestone:** Complete remaining 7 racks
|
||||
|
||||
### Existing Infrastructure
|
||||
|
||||
SITER has the following energy infrastructure already in place:
|
||||
|
||||
| Component | Details | Install Date |
|
||||
|-----------|---------|--------------|
|
||||
| Base Power Battery System | Battery backup with automatic transfer switch | 2024 |
|
||||
| Automatic Transfer Switch (ATS) | Seamless grid/battery switching | 2024 |
|
||||
| Base Power Contract | 3-year fixed rate at $0.085/kWh | 2025-2028 |
|
||||
|
||||
**Site Base Load:** ~1,885 kWh/month (15-month average)
|
||||
|
||||
This existing infrastructure significantly de-risks the solar project:
|
||||
- ATS already installed for grid switching
|
||||
- Battery backup provides load smoothing and outage protection
|
||||
- Fixed-rate contract provides predictable baseline costs

### Assumptions
|
||||
|
||||
- NREL PVWatts production estimates based on TMY (Typical Meteorological Year) data
|
||||
- 60% self-consumption / 40% export split (conservative estimate)
|
||||
- System losses of 14% (inverter, wiring, soiling, etc.)
|
||||
- Electricity rates remain constant (conservative - rates typically increase 2-3% annually)
|
||||
- No major maintenance required in first 10 years
|
||||
- Base Power contract at $0.085/kWh remains in effect through Oct 2028
|
||||
- Base Power solar buyback at $0.04/kWh continues
|
||||
- Solar integration with Base Power system is technically feasible
|
||||
|
||||
### Key Considerations
|
||||
|
||||
**Production vs. Consumption Gap:**
|
||||
- Current consumption: ~22,600 kWh/year
|
||||
- Solar production: ~6,000 kWh/year
|
||||
- Gap: ~16,600 kWh/year (73% still from grid/Base Power)
|
||||
|
||||
**Options to Improve Economics:**
|
||||
1. Upgrade to higher-wattage panels (400W+ panels reduce payback to ~6 years)
|
||||
2. Expand system size (additional panels/racks)
|
||||
3. Reduce consumption through efficiency measures
|
||||
4. Add more panels when costs decrease
|
||||
|
||||
### Value Adds Not Quantified
|
||||
|
||||
- **Energy Independence:** Already partially achieved via Base Power; solar adds generation capability
|
||||
- **Property Value:** Solar installations typically increase property value
|
||||
- **Environmental Impact:** Reduced carbon footprint
|
||||
- **Existing Battery Storage:** Already in place via Base Power system
|
||||
- **Rate Hedge:** Protection against future electricity rate increases post-2028
|
||||
- **Redundancy:** Solar + Base Power + Grid provides triple-redundant power architecture

## Recommendations
|
||||
|
||||
### Immediate Actions
|
||||
|
||||
1. **Approve Budget:** Authorize $4,100 project expenditure
|
||||
2. **Order Inverter:** Confirm Sol-Ark 5K availability and place order
|
||||
3. **Complete Site Survey:** Determine exact wiring requirements and costs
|
||||
4. **Verify Permits:** Contact local building department to confirm requirements
|
||||
|
||||
### Panel Upgrade Consideration
|
||||
|
||||
Based on the updated analysis, upgrading from 250W to 400W panels would:
|
||||
- Increase production from 6,004 to 9,606 kWh/year (+60%)
|
||||
- Increase monthly savings from $33.52 to $53.63
|
||||
- Reduce payback from 10.2 years to 6.4 years
|
||||
- Increase bill offset from 12.7% to 20.3%
|
||||
|
||||
**Recommendation:** If budget allows, consider sourcing 400W panels instead of using existing 250W inventory.
|
||||
|
||||
### Project Execution
|
||||
|
||||
1. Continue rack construction using proven design from Rack #1
|
||||
2. Procure all remaining materials in single order for cost efficiency
|
||||
3. Consider hiring licensed electrician for final grid connection
|
||||
4. Document entire process for future reference/expansion
|
||||
|
||||
### Future Considerations
|
||||
|
||||
- **Base Power Contract Renewal (2028):** Evaluate contract terms vs. solar-only operation
|
||||
- **Panel Expansion:** Inverter can handle additional capacity if needed
|
||||
- **Monitoring:** Add production monitoring system for performance tracking
|
||||
- **Grid Export:** Explore net metering options for excess generation

### Base Power Solar Economics
|
||||
|
||||
**Consumption Offset vs. Export Credit:**
|
||||
|
||||
| Scenario | Rate | Benefit |
|
||||
|----------|------|--------|
|
||||
| Solar consumed on-site | $0.085/kWh avoided | Higher value - reduces energy charge |
|
||||
| Solar exported to grid | $0.04/kWh credit | Lower value - but credits apply to entire bill |
|
||||
|
||||
**Optimal Strategy:** Maximize self-consumption during peak production hours (run high-load appliances when solar is generating) to capture the $0.085/kWh value rather than exporting at $0.04/kWh.
|
||||
|
||||
**Key Advantage:** Unlike many providers that only credit against energy charges, Base applies solar credits to the **entire bill** including delivery fees, taxes, and the $10/month subscription fee.
