Not meaning to comment positive, negative or criticize, but I find it astonishing that their gallery has so many panels mounted on roofs. I know for a fact, after operating off grid solar for 30 years, that aim (compass position) as well as tilt has to be right on, or you lose a lot of power. Just how many houses have the perfect roof slope and aimed exactly right? I don't see any lift on the top and bottom of the arrays to compensate. Again, not a criticism, just amazing.
