🌞 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 Review

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…

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…

Unlike other solar panel maintenance tools, there are no eyelets for attaching the panel directly to the battery terminals. I modified it with ring terminals and a 5A fuse. I keep the solar panel on the rear shelf of the car (Camry Hybrid) with the wire going to the trunk where the 12 volt battery is located (this takes a lot more work on most cars with an under the hood battery). ). The cigarette lighter plug is useless on most cars because the cigarette lighter socket is not connected to the…

Only about 4 watts at absolute peak, about 16 volts (manually "Tracking Maximum Power Point" was done to find it), in Texas at noon, just before the summer solstice. At 13V to charge the battery it's more like 3W as it's an almost constant current source so lower voltage means less current. 2 stars only because the rating is ridiculously overrated. I would leave it at 5 watts. And the "junction box" doesn't appear to be sealed on the back, but I didn't pry it open to be sure. If you're using it

The panel itself looks good quality - nice and sturdy and I get a great charge on my small 32Ah deep draw cycle in a closed trailer. I used to have a tiny 3 watt solar panel and it wasn't enough to keep the battery charged. With two of those 10-watt panels charging at over 1 amp, he shouldn't have a problem now. Looks great installed and feels very solid. A major issue that turned a 30 minute install into a 3 hour ordeal was that no hardware was included to install! I knew this when I bought…
