PV water heating
sawmill Posts: 90Solar Expert ✭✭✭
I have 2- (unused) 290w panels, 39.4voc, 9.5 isc that I want to use on a17 gal preheat tank for Rennai. Is there any advantage to wiring them in series or parallel or does it make any difference? Also would there be any difference to what watt element is used since all available PV wattage is being converted to heat?
