Review on 🌞 Highly Efficient PV Module - Newpowa 10W 12V Monocrystalline Solar Panel for Enhanced Battery Trickle Charging in Boat, RV, Gate Opener, Fences, and Off-Grid Applications by Adam Nelson

I bought 2 of these at different times. I bought the first one to charge a 6Ah 12v battery in my shed to power multiple 12v fans in the temperature loop to keep it ventilated in the heat. I just bought a second one as an upgrade to add extra power for a couple more fans and installed it on the solar controller I bought. It keeps both batteries fully charged even with the fans running all day, even on inclement weather days. not perfect. . The only thing that confuses me is that they are difficult to assemble. The screw holes are hard to reach so I tied them to the barn roof. I assume they are made to fit the rack and I couldn't find one that worked. Worth the money but needs to be outfitted with a controller as the no-load peak power is 22V (normal for a solar panel if you didn't know). Without it, a 12V battery will be killed.
