Why not approach the problem from all sides? There are big renewable projects in Germany as well, of course, but they take time to build, the grid needs to be adapted to handle them and there are many, many people/organizations who oppose all big installations that "block their view of nature" or whatever, so the big projects take even longer. By the way, this (nasty neighbours) would be a big issue for Balkonkraftwerke as well if they had not added them to a list of privileged things you are allowed to equip your house with (without permission process).
