Goal: Calculating the power production of your solar installation and predicting your solar energy for the next 7 days, also available as an API for integration with a HEMS (Home Energy Management System) like Home Assistant or others.

Calculating:

• clear sky Power (Watt) for any given time of day
• clear sky Energy(kWh) for any given day
• Typical real Energy (kWh) per month and Totalper year

Predicting:

• Power Prediction (Watt) for any given time for the next 7 days (or 48h)
• Energy Prediction (kWh) for the next 7 days (or 48h)
• Typical Prediction (kWh) per month and Totalper year

There are 2 parts:

API:

api.solar-forecast.org is the main part, typically used as a service for a HEMS (Home Energy Management System). The API gets the installation data in the body of a POST request and provides a response for the clear sky or prediction. You can optionaly specify a "weather provider" (open-meteo or openweathermap) by adding a "query" parameter provider in the POST request.

See details or perform tests in the swagger documentation.

Example:

curl -X 'POST' \
  'https://api.solar-forecast.org/forecast?provider=openmeteo' \
  -H 'accept: application/json' \
  -H 'Content-Type: application/json' \
  -d '{

UI - User Inreface:

This is a web application www.solar-forecast.org for visualizing the prediction or as aid for calculating your PV installation or exploring different orientations, dimensions, tilts or seasonal influences like winter and summer.
