OK, just a quick for grins.... there is a demonstration solar installation in Hilo... have seen it tons of times... just today I realized both sides of the roof have PV panels, one is due south.... the other is due north, pointing right out to the bay.... have seen them countless times, even from a boat on the water & only today did it click that those are north facing panels!
