Description
- 【Dimension】27.76*56.69*1.38inch. High winds (2400PA) and snow loads (5400PA).
- 【Maximum power (Pmax)】200W, Voltage at Pmax (Vmp):18.6V, Current at Pmax (Imp): 10.76A.
- 【22.68% Conversion Efficiency】
- 【Easy Installation】Solar panels diodes are pre-installed in the junction box, with a pair of pre-attached 3ft solar connectors cable.
- 【Newpowa Bifacial Solar Panel】Newpowa’s bifacial 200w solar panels can generate electricity from the back! The Newpowa bifacial solar panel’s back can generate electricity from reflected light coming from the ground, etc. The more reflective the ground is, the more light can absorbed by the back of the solar panel. The electricity generation will also be better. (Based on our installation experience, the higher the height from the ground, the more effective the back gain will be. We would recommend you install this solar panel preferably between 28-50 inches above the ground.)
- 【Accelerating Melting Snow Covered on Solar Panels in Winter】When traditional solar panels are covered with snow in winter if the snow on the surface cannot be cleaned up in time, the solar panels will easily freeze in the continuously low- temperature environment. This will not only affect the electricity generation but also may cause unpredictable effects on the solar panels. Even if the surface of Newpowa’s bifacial solar panel is covered with snow, the back can generate electricity by absorbing the reflected light from the snow, accelerating the melting and sliding off the snow, thus increasing the electricity generation capacity.
- 【After-sales Service】 With a 2-year material and parts workmanship assurance.10 years of power output is greater than 90%, 25 years of power output is greater than 80%.

This panel comes very close to outputting 200 watts. It’s well-built and a handsome unit. I will be replacing all of my many-years-old panels with these. An excellent value.

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.

Panel arrived in perfect condition. Box was undamaged and panel was very well protected as packaged. Ordering and receiving a solar panel via delivery is always a crapshoot. They are large, awkward and easily damaged during transport. FEDEX has a horrible track record and I was so relieved to discover my latest purchase would be delivered via Amazon. Driver was very professional and package was received in immaculate condition. Arrived too late to test( will do tomorrow) but by all indications of outside of box, I anticipate zero issues. 5 stars and 2 thumbs up for Amazon and NEWPOWA. This is my second order of bifacial panels and they are gorgeous.

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.

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.

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.

This is my third installed on my RV in series. The first two were 210 watts and after much research I decided that this 220 watt should be close enough to mix and match. I measurd output with two hooked up and then with three. The third panel just adds a third more watts as it should. If I shade the panel partially, it still makes decent power.

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.

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.
