With this python library you can request data from forecast.solar and see what your solar panels may produce in the coming days.

pip install forecast-solar

This library returns a lot of different data, based on the API:

• Total Estimated Energy Production - today/tomorrow (kWh)
• Estimated Energy Production - This Hour (kWh)
• Estimated Energy Production - Next Hour (kWh)
• Estimated Energy Production - Remaining today (kWh)

• Highest Power Peak Time - Today (datetime)
• Highest Power Peak Time - Tomorrow (datetime)
• Estimated Power Production - Now (W)
• Estimated Power Production - Next Hour (W)
• Estimated Power Production - In +6 Hours (W)
• Estimated Power Production - In +12 Hours (W)
• Estimated Power Production - In +24 Hours (W)

• Timezone
• Rate limit
• Account type
• Rate remaining

• API key (bool)
• Plane (bool)

This Python project relies on Poetry as its dependency manager, providing comprehensive management and control over project dependencies.

You need at least:

• Python 3.11+
• Poetry

Install all packages, including all development requirements:

poetry install

Poetry creates by default an virtual environment where it installs all necessary pip packages.

This repository uses the pre-commit framework, all changes are linted and tested with each commit. To setup the pre-commit check, run:

poetry run pre-commit install

And to run all checks and tests manually, use the following command:

poetry run pre-commit run --all-files

It uses pytest as the test framework. To run the tests:

poetry run pytest

To update the syrupy snapshot tests:

poetry run pytest --snapshot-update
