Add Open-Meteo solar forecast

[mgoetting]

Current forecasting via forecast.solar or solcast have some downsides related to rate limits you can easily run into with more than one panel orientations and also acurassy in my case with forecast.solar, even with paid subscriptions.

I have been using open-meteo Integration in home assistant for a while which had forecast.solar as a base but uses the open-meteo as data source:

https://github.com/rany2/open-meteo-solar-forecast

https://open-meteo.com/

The results were much better and you usually dont need a subscription for non commercial use and they have high rate limits due to their terma & conditions.

They dont really advertise solar forecast Part of the API specificly on their page, but maybe you can have a look in the HA Integration / Python Module how its done.
