Moderators SeaDawg Posted March 3, 2019 Moderators Share Posted March 3, 2019 Back in the early fall, 2008, we had 200 watts solar installed on our Elite. Last year, we installed a 12v refrigerator, which adds to our electricity appetite. We also picked up an inexpensive Coleman 100 watt panel, to use as a "suitcase" solar, though it doesn't fold. Last fall, Oliver installed a Furrion port for us. Paul recently wired it to our solar controller. Today, we had a nice clear day, and I tried some tests on the Coleman panel, just to see what we could expect. Yesterday, Paul covered our existing fixed panels with dark moving blankets, so I could record readings only from the portable panel. Yesterday, feeling really decadent, I purposely ran down the batteries so I could get to bulk stage charging. Not essy to do, with all led lighting. Ran the front jack up and down a few times. Tried running the power hog furnace fan awhile. But in 78 degree weather, I had to turn it off after awhile. Finally, started today with 20 hours down, leaving both exhaust fans on overnight. Our $100 /100 watt panel recharged the battery in less than four hours of full sun. But, when I covered some cells with another blanket, I saw a huge loss of power coming in. Even two cells covered lost 50 per cent. 12 cells covered obliterated any gain. The good news is, I think I can manage between the cheap portable panel, if i can keep it out of the shade, and our much better quality fixed panels, and not have to run the generator most days. We honestly didn't expect a lot out of the Coleman, but in full sun, I was getting 5 amps in. It will definitely require attention, though, to keep the batteries up.
