Newpowa 220W Monocrystalline Solar Panel 10BB Cell Solar Panel Off-Grid Charge System for RV Marine Boat 220Watts (220w)

I was able to hit 182 Watts after re-alignment, that's about 86% of their rated output ....which is very good. I will be grabbing 2 more of these now that I have tested their performance. (For my MPP Solar 1012LV-MS project). Product came well packaged with no damage, highly recommended. People need to learn about how these work before they post bad reviews. All panels have a rated wattage output. Example: A 100w panel simply means it can have a 100w DC output under "Optimal" conditions. This includes unobstructed sunlight/proper angle alignment/power drop in cabling-etc. And the time these panels are in that perfect zone is maybe 5 hours a day. And remember, panels will pull only how much is needed. If your battery is charged and you're only using 150w factoring in inverter efficiency, don't expect panel to pull more wattage than is needed unless you are grid tied...it just doesn't work that way. I get 500-550w on any normal day with 3 of these 210w panels ,Off-Grid and very pleased with that performance. it recharges my 200AH Lifep0 battery from the night before and powers a basic home office at the same time. No issues.

I now have 10 of the 220W Newpowa panels. The first six I ordered worked so well that I got four more. Well made, no problems at all, and all of them worked exactly as specified. The packaging they come in is almost bullet proof as well. Despite some rough handling by the delivery service all of the panels were unscathed when they arrived. In actual use they work as specified. In excellent weather conditions they are putting out almost their full rated power, even up here in Wisconsin in less than ideal circumstances.

I bought two of these and mounted them to the top of my mobile office setup. Power output has always been great, even in mediocre conditions. The build quality is good, and I haven’t had any issues with them. The aluminum frame makes it easy to suit them to your needs. Just drill to your hearts content and mount them up. The advertised 210W is pretty accurate from what I’ve seen. You’ll see a few people in the ratings contend whether or not these are truly 210W, but I’d say they’re pretty spot on. On a clear day in TX I was pulling around 80% of the rated watts (they’re wired in series). More often than not the rating given to panels is in the absolute best case scenario, so keep that in mind when shopping around. Overall these are great panels. Serious value for the price and I highly recommend.

Bought two 220W panels in 2022. They worked flawless until 2026 when one panel stopped delivering any output. It had a spider web pattern under the glas. Contacted Nepowa. They answered my email after some hours. Asked for images and serial number. After reviewing the images they agreed to replace the faulty panel. Answer came also only hours after receiving images. Off course it would had been better if the panel would not fail. So I give the panel ***. But customer service was top notch. Could not be better so they get 5 +. ********* As they treated me so good I decided to order additional panels from them.

Check with me in a month. i'll be using 10 220w modules for the primary power on a small passive solar home that I'm just now finishing in the Mendocino Natl. Forest in Lake County, CA. So far I like the build quality and the size (easy to handle). I'm doing a ground mounted array as the panels can stay cooler in hot summer weather and produce more wattage. I'd prefer the frames were black bot you can't have everything. KT

UPS delivered panel. Arrived in perfect condition. Couldn't wait to try it out. Set it up in a shady place, late afternoon, and watched as it started to charge my Lifepo4 batteries. In the shade, voc was 18.1 volts. Current from the panel was 1.1 amps. Current going in to the batteries w was 1.3 amp. How do you charge with more amps than the panel outputs? Enter MPPT! Built a frame for the panel and set it up in sun. 19.3 volts but only 2 amps. Took a reading at the panel and got over 9 amps short circuited. Checked amps at end of my 30' set of solar cables, 10AWG. and only got 2 amps. Panel works as advertised or even better. I will be buying another one soon. Definitely need to try some #6 wire to get more power to the charge controller, Panel was generating 3 volts in moonlight a few nights ago. Nothing wrong with this panel!!!! Definitely recommend! Update 9/2 Received a second 210 Watt panel and paralleled it with my first. My yard is very shaded with a large tree, so panels only get full sunlight in the afternoon. Panels provide energy from before sunup to after sundown, albeit only an ampere or so. It still charges! This afternoon I noticed my charge controller had stopped charging in full sunlight. Quick troubleshooting determined that the solar input fuse had blown. Replaced fuse and controller started charging again. I had a 20A fuse inline with the first panel and never had any problem.. With 2 panels, input current was 23 amps in full sun. What a happy problem!! 25 Amp fuses handle the new configuration very nicely and batteries really charge quickly. Very pleased with Newpowa panels and highly recommend for less than perfect situations.

The tiny little Juice Pack at 50w was not enough in my new Wolf Pup travel trailer. I would be out of power in 1.5 days and have to charge up via generator or plug-in. After adding a second deep cycle battery, I mounted this solar panel on the roof and a Newpowa 30A MPPT Solar Charge Controller inside. It was a bit of a project, but now I can boondock indefinitely. In the California sun, my batteries are always registering >13 volts with the refrigerator running 24hrs. I have tested it for 14 days straight - never needed to plug in. Don't forget mounts, cables, polymer Epdm self-leveling lap sealant for the roof, and a cable entry gland.

Delivers the power I need! What I expected it to do. Do your research before a bad review about how a solar panel works, tilt, clouds, direct sun, etc ..... I have mine flat on a utility trailer roof and fully expect NOT to get the full power out of it. However, I am getting 10-12 amps per panel (I have 3) just sitting flat on the roof during direct over head sun in northwest florida. Your area will be different than mine unless you point your panels directly at the sun and move it as the sun moves. Its how panels work. Great product, pretty sturdy, great charge. Edit: I did a voltage reading at 4pm as the sun is headed to the west and read 18.73 volts
