200W Mono Solar Panel

I am very happy to write this review, I bought this 200W panel back in 2020. I have gone through more panels than I would like to admit. ( I started out with Flexible panels) but that's a whole other story. This panel has been my "GO TO" panel as I use it as one of my mobile panels when I RV. It can live a rough life sometimes. Yet it never disappoints me as far as, its always pulling in Good numbers. So after replacing all the flex panels, I'm adding a second 200W to my array. I am really looking forward to this addition. The pictures are of my original panel, still looks great and performs just as great. Stay tuned,

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.

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 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.

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.

The only problem I have encountered with this panel is the shipping. Newpowa and/nor Amazon mark the packing as fragile. It took me three tries to get one unbroken panel. The previous three panels I had ordered were delivered intact and in perfect condition. But not the fourth one. They're good solar panels and I'll purchase more if/when I need more. In spite of the danaged panels, Amazon and Newpowa made it right for me and in a timely manner. These Newpowa 200 watt panels are well built and work well! If they would take care of their shipping problems, which fragile stickers would probably help, I would personally endorse the purchase process as seamless.

I ordered four 200W panels. Well, two arrived on time. One more arrived a couple days later. The fourth one was "delivered" a couple days after the third, except that it was completely the wrong thing (it was a wire guide or something like that). I returned that and it took about 10 days to get a refund, ehich took three phone calls to Amazon and finally they manually pushed it through. In the meantime, I ordered a replacement for it, which arrived... smashed. That's when I noticed that the fourth panel was smaller than the others. So I measured the first three and discovered that they are, in fact, 65 inches long instead of the advertised 55, which is a game changer for me since they're too long for me to install them on my boat. Now I have to return the other three, pray they refund me, order three more, and hope they are the correct item. This has been a nightmare. UPDATE: This was all Amazon's fault since they fulfilled the order. They have been less than helpful trying to resolve these issues along the way. However, when I contacted Newpowa directly, they were the most helpful people I have dealt with in a very long time. They made this all right on their own, even though it was Amazon's mistakes that got this order all screwed up. A+ for customer service! I will definitely deal with them directly in the future and would recommend the same for anyone interested in their products. I got three new panels in three days from them without even having to return the wrong ones first. They really are a great company! And the panels are excellent for the application. Much better output than other brands I've used.

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.

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!
