Dutchman here (Germany's neighbor). 'Green' forces in my country set new rules so the government actually pays a part of the costs if you buy and install solar panels on your roof. The very same government who puts up an import-fine for those very same panels thus making them more expensive. Now that a lot of people have bought and installed solar panels and have become net suppliers of power (giving it back to the grid) they're working on new rules to administrate those net-suppliers. They now run the risk of having to document everything like regular power-providing companies do. (Lots of red tape). Thanks government...
