The POST method will be removed until end of 2023!

You can send actual production data to adjust the forecast matching your actual real production, it will affect only the actual day, not the next days.

The internal correction observes all planes and corrects the forecast as a whole.

Please note that if you send correction data very early in the day, this can have a massive effect on the daily forecast!

Submit the actual absolute plant production direct during a forecast request.

With any call for a forecast

https://api.forecast.solar/:apikey/estimate/...

you can direct add a query parameter (always in absolute kWh)

?actual=<float kWh>

In the message > info section of the response the used corrections will be included.

Just in case, to reset the correction factors and delete the actual value just send 0.

?actual=0

Deprecated from 2024
