Shocking Lesson: I was preparing to show my solar prius one day and used a damp cloth and water to wipe the dust off the 11 solar panels. At first I felt a slight tingling here and there and then went back to the same panel and got a good shock. My panels are fiberglass composite so that they bend slightly and were all connected in series to get to 250 VDC for directly charging the Prius battery. After several years (and this event) one could see water incursion, discoloration and corrosion that had crept into the solar cell layer (sandwiched between the fiberglass substrate and the polymer sealing top layer.. The depth of the edge incursion was as high as 1/2 inch in some edges. The problem was obvious! And I had seen it coming in fact, I know that I did an initial poor quality sealing job, but figured I'd get back to it some day to do it right. Never did. until I scraped the car 14 years later See image of solar cells: about 50% down this page: http://aprs.org/FD-Prius-Power.html Bob, WB4APR -------------- next part -------------- An HTML attachment was scrubbed...
