I think that Windfinder is worth a look as well: https://www.windfinder.com/#10/52.2206/6.0013 Nice thing about them is that they're client orientated. I sent them an email a while back about something on their website (the +/- buttons) and I got a reply asking if I wanted to talk to them on the phone about it. I gave them my number and Jan, one of Windfinder guys, and I had a nice conversation about the website, their forecast models etc. Recommended
Next to Windfinder, I tend to use Windguru as well: https://www.windguru.cz/48267
