Rooftop solar is huge in Holland because they still allow the users to detract their delivered kWhs from their bill. Regardless of the price at that time. It's called "salderen". This makes deploying solar panels highly cost effective but it basically makes daytime summer power so ubiquitous that they're having a hard time using it up. And on a global scale it's a waste of resources because Holland doesn't get an awful lot of sun. Meanwhile in Spain almost nobody has panels because they only get the momentary value which is not worth it during sunny tints unless you use it to run your own AC.
