Newpowa 220W Monocrystalline Solar Panel 10BB Cell Solar Panel 220 Watt 12V High Efficiency Mono Module RV Marine Boat Off Grid

Wonderful product. I wanted to buy 3 more but I guess they're out of stock for now. I'll keep looking

This works as advertised and works with my Oupes Explorer. For this price, it's like getting the MPPT Controller for free.

THREE PANELS CONNECED IN SERIES. GREAT OUTPUT. PURCHASED AT A LOWER PRICE THAN CURRENTLY INDICATED.

I test a lot of solar cells. These are an excellent value and a recommended buy. So why only 4 stars? Because this, like almost all solar companies, claims a "theoretical, lab-value" wattage, not what they actually produce. Until they start advertising wattages at close to real world conditions, then they will not get 5 stars from me. Test Conditions: Florida, April, Clear sky, noonish, 75 degrees, panels pointed directly at sun (so pretty much real-world ideal) Epever Triron MPPT 30 amp charger, LiFEPO 175 AH battery about half charged. Two Newpowa 200watt (claimed) panels tested. They averaged about 170 watts during my test (varied between 165 and 175 with perfect sun). That's an 85% actual-to-claimed wattage, which is fairly typical. I saw 11.3 amps (at 15.4 volts) output, which is pretty close to their claimed maximum operating amps of 11.76 (but they claim that at 17v, hence their 200 watt claim). Keeping all that in mind, I connected both in series and the MPPT charger was pumping a pretty steady 23 amps into my battery at around 13.7 volts - pretty nice for two panels of this size range. The power per square foot comes out pretty comparable to similar panels I've tested in lower wattages. They almost come out to $1 per watt which should be a target for anyone looking for solar panels now. You can get some for slightly less than $1 per watt but then you need to factor in support, reliability, warranty, etc. One of my favorite panels is the RICH SOLAR 50/80/100 Watt 12 Volt ETFE Flexible panel - they reach claimed wattage and are tough and lightweight, though more expensive per watt than glass frame panels because they are flexible (but they are great for extra panels that need to be portable). The BougeRV 170 panels are nice too. If you don't know how to test a panel, please don't post a review about them not delivering power. I highly recommend the Epever Triron MPPT chargers. I have two and will probably buy more.

I purchased it to power our pond aerator. Electric wasn’t an option. Provides the amount of power as advertised. Definitely worth the money.

I already bought 3 panels, they lived forever in my cabin on the back wall. This summer, I installed them, and got my solar up and running, then I realized I had to have another panel. So I went and bought another, it arrived USPS, not FEDEX, and the local post office is a small rural one, the first three panels I had to go and fetch on my own, and transport home, and the third they did put in a van and brought, I met them to fetch it and of course, had to get them to the cabin myself. They were fairly easy to install overall. The fourth panel is smaller and rated higher then the other 200 watt panels (800 total) - I hooked everything up, three panels in series and the last panel, the new one is on it's own circuit. Then I finally got the inside guts in place, and SURPRISE!!! I was topped off and fully charged up by sunset that day. Hummm.... ever since I am amazed at the fact that it takes no time at all to top off and I am doing well so far. The real test is to come - will it run the fridge\freezer 24/7 it says it is only 1 amp. We will see. Due to the drought, I had a fire ban, I found it impossible to live in the cabin long term. So I went looking for some "power" ways to cook, and I will test them in the year to come. I have nearly 5500 WH at my disposal at 1000 watts. so I will be putting the system to the test. I even have found a AC that is rated about 500 watts and that alone would run me 7 hours. So expanding is going to have to take place, wish they had single 500 watt panel - maybe someday, I would need 2 of them to get to where I can keep 3000 watts at nearly 6000 WH [a new system] - in addition to where I am now - all this to say I am impressed, now let the games begin as we winter and summer again. As storms test the panels, etc....so far so good... Yes, I will look at buying again - at least at this point.

We purchased these panels due to their value, size and price and couldn't be happier. We installed them with custom brackets on the roof of our sprinter van. High quality, sturdy materials, functionality is good. Value for the money is spot on. I would definitely recommend these for RV/Motorhome use.

Working good, at 230 pm laying flat is producing 108 watts and 8.17amps. Going through a Wanderer 30 amp charge controller.

Installed 2 of these on our 2011 Leisure Travel Sprinter RV. Work very well at charging the 2 6v golf cart batteries. Installed one of them with 3M VHB tape on the bottom of the footings and Eternabond tape on top of the footing. No screws into the camper. Be sure to clean the surfaces with isopropyl first before applying the tape. Both tapes are impressive and that panel is staying put.

Delivery was faster than expected, product performs as advertised. I have installed two 200W panels on my boat, no more battery issues, at peak, 22A at 325 W.

These panels will be going on my RV so I tested them and each panel put out approx 190w each and 384w for 2 panels wired in series which is awesome for January here in Canada.

On bright sunny day, Vmp=20.2 volt, Imp: 10.2 amp on a good solar angle. I was able to get up to 11.763 amp.

Rendement efficace et instalastion facile!
