About

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

Installation

pip install open-meteo-solar-forecast

Data

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

Energy

• 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)

Power

• 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)

API Info

• Timezone
• Rate limit
• Account type
• Rate remaining

Validation

• API key (bool)
• Plane (bool)

Example

import asyncio

from open_meteo_solar_forecast import OpenMeteoSolarForecast


async def main() -> None:
    """Show example on how to use the library."""
    async with OpenMeteoSolarForecast(
        latitude=52.16,
        longitude=4.47,
        declination=20,
        azimuth=10,
        dc_kwp=2.160,
    ) as forecast:
        estimate = await forecast.estimate()
        print(estimate)


if __name__ == "__main__":
    asyncio.run(main())

Parameter	value type	Description
base_url	str	The base URL of the API (optional)
api_key	str	Your API key (optional)
declination	int	The tilt of the solar panels (required)
azimuth	int	The direction the solar panels are facing (required)
dc_kwp	float	The size of the solar panels in kWp (required)
