Newpowa 10BB Cell 200W Monocrystalline 200 Watt 12V Solar Panel High Efficiency Mono Module RV Marine Boat Off Grid (200W New)

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.

Excellent quality and works great.

I bought four of these to replace three panels on the roof of my RV. They were smaller than the original panels since they are higher efficiency. The build quality is fantastic and the packaging was great. They arrived with no damage and the thick foam makes great drawer liners!! The panels are functioning very well keeping my batteries fully charged, even on cloudy days.

I bought 4x 200 watt panels to connect to my Bluetti AC200P. I tested them last week in cloudy conditions and i'm pretty sure they were not angled very well to maximize their efficiency. During that quick connect test i only got 50-110 watts. That left me concerned. On 22MAR21, it was sunny so i connected them again to see what they could produce. Attached are the images. My AC200P has an input of only 700 watts, so i was over paneling with 800 watts. I still brought in over 700 watts. Objective met. Then I disconnected one panel and tested it again. The three panels yielded over 500 watts continuously. It mostly stayed around 520-538 watts. I'm not an expert at efficiency of solar panels, i'm really just a newbie with some basic research. I thought these panels were good stats for their price. I'm happy with them. After purchasing, I maybe should have looked at getting 24v panels instead of 12v given the specifications of my AC200P voltage range. With these panels i must employ 3 panels to get enough volts to charge my unit. At the end of the day, i'm still happy with the purchase and think it's a good one.

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.

0 issues after 6 years and if there's been degradation after 6 years of constant use, I can't notice it. Originally bought 3 for my van conversion build and later bought a 4th since I had some spare roof space. There may be better panels on the market now, but these ones certainly hold up and for the price, I wouldn't roll the dice to try another brand should I need to replace a panel in the future.

I've installed two of these and gotten over 300W in the Sacramento Valley where the sun is intense. This is about par for the course and my 100W Renogy panels deliver about the same (about 75% of panel rating. The number will vary from day to day so I'm sure on some days I'll get closer to 400W just as my Renogy panels do. The real test will be when camping at 7500 feet elevation. There are places where my 100W Renogy panels have delivered 125 Watts largely due to the hole-in-the-cloud effect but in part due to the clear air. Of course at 7500 feet one expects more power than the industry standards used to spec panels. The frames on these panels are adequate. I had no problem with flexing when I lifted one corner to put goop under a foot (other side screwed down, same side foot free to rise). The frames are not heavier than my Renogy 100W frames in spite of the larger panel, but more robust frames would mean more weight on the RV roof and I don't need or want that. The open circuit voltage of about 24V is fine for either series or parallel operation. I'll update when if needed.

I got lucky and picked up 6 of these panels on sale for $169. This turned out to be the best deal I have ever got. The price is just half of the deal. These panels are wired 2S3P, flat mounted into a Victron Smartsolar 150/70 MPPT controller. It is January and I'm in south east Texas. On a sunny day, my max current has been as high as 52 amps. The size of these panels are not much bigger than a Renogy 100w. I am averaging 58% efficiency. I am considering tilting them about 45º. I could not be happier.

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!
