I added Forecast.Solar in the latest test version.  
It is a slightly different approach than Solcast.

- no need for API keys
- just add all the parameters when adding your PV installation.

1. kWp of your installation (use . as decimal)
2. -Orientation of solar installation (180 = south, 0 = North)
3. Tilt/declination of installation (0= flat)

You can add multiple installations.

API Limit: 12 request by hour, updates of forecast are hourly.  
The app automatically updates the values every hour, no need for flows.

If there are bugs, let me know
