We built a new garage for our new electric cars. We insulated the garage so that we could heat it to 41 degrees with electric heat from our panels to keep the batteries from freezing. Hmmm, more room for PV! We used 16 panels with micro inverters and fed it by AC Coupling to our Xantrex XW system. That way, if PSNH goes down, the panels are still on the job!
