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 Kyle Wesener

I wish the manufacturer had included mounting hardware, but the actual solar panel is excellent. It delivers rated power and works great even on cloudy days to keep my 12V Li-Ion 18650 battery charged on a daily basis. I use my aquarium pump 24 hours a day with this DIY solution. Oh, by the way, I used a Renogy Wanderer 10 Amp Solar Charge Controller to protect the lithium ion battery pack from overcharging on very bright sunny days. However, like other reviewers who have commented, I too had some difficulties installing this on a roof. I had to improvise and bought additional mounting hardware from a local store and drilled additional holes to mount it on the roof. .Four star product rating!
