I’m still looking for a good solar energy harvest prediction service and I found Fronius SolarWeb (which I’m paying for anyway) to be free for small query sizes in various older posts. Regarding that, they were very non-specific regarding what it costs now or what it might cost if something runs amok and queries often.

I jumped through their hoops and contacted sales under the premise that I’m planning to implement something et voila, an actual pricelist.

Completely out of the question for private users, of course, but at least that info is public now.
