Re safety. My original solar prius used 15 series panels to get to 240 VDC to parallel into the HV DC system. Worked great... BUT after a few years, I noticed that while washing the car in the sun, I'd get little shocks each time my sponge went over the edge between adjacent fiberglass solar panels. THey have been on the car for 13 years and "edge effects" show weather slowly weep[ing into the edges of the panels.
