@ Roger Asbury The article does not mention a survey (as in customers answer questions) at all.
I don’t have a problem with Republicans going solar, the opposite in fact if they can convince their Congressvarmints to quit making laws inhibiting others from getting it too.
However, research based on the general voting pattern of an area is a flawed basis which must deliver flawed results.
I am a Democratic Socialist and live in an area that is so right wing it wants to secede from the state. I would never even put a bumper sticker on any vehicle I own as it would be asking for vandalism or road rage. I have a 64KW array that delivers 95%+ of my power needs year round.
