@WeatherMan10 No, that is another issue. It was not possible to send solar radiation in the previous API version, so it was not implemented in Windy either. However, there is no reason for that now. I have already reported it to the frontend team.
@gptwisted Thanks for letting us know. The bug was in the documentation and it has now been fixed. Previously, it was possible to request 30 days, but we had to limit it to 7 days. It was causing a huge load on our systems as the number of requests increased.
