PowerECO 200 Watt 12V Monocrystalline Solar Panel with Solar Connectors, High Efficiency Module PV Power for Battery Charging Boat, Caravan, RV and Any Other Off Grid Applications(1 Pack)

Bought 10 of these 200w panels to mount on my RV, I was so impressed with the material/build quality and the power output for their size that I ordered another 6 panels for another RV. Each of the 16 panels were very well packaged inside the box with foam on all four sides and front/back of the panel but 1 of the 16 panels was damaged by FedEx... damaged bad enough by FedEx that it ripped the box open and smashed the frame around the glass but the glass didn't crack which was surprising from the shipping abuse it went through.Anyway Lynn at PowerEco resolved the issue immediately with no hassles... of course it wasn't PowerEco's fault at all but they had a new panel out to me in no time.... Great customer service as well as a great product.

I have them flat facing upwards and still work great.

( edit 5/22/24 ) have had time to compare them they produce 10 watts more per panel than the other 100 watt panels by a different brand I in the same conditions so I am quite happy with the performance.Arrived in good condition packaged well, no damage both seem to put out the same amount of watts. Today is a less than stellar day for solar patchy Sun so I can't say how much they put out on a good day. Have three older panels that I will be using with these. These are same size and specifications are almost identical. Price is much better than when I bought my original three panels. So I am happy will be making a solar suitcase with this pair now that I know they work.

I installed this on my car, and wanted a solar panel that was in all black and didn't scream solar panel. This panel is the one to get if you share the same sentiment! Aside from the fact that it worked well when hooked up to my battery, I haven't had the chance to use it long enough to give a comprehensive review on efficiency. It looks to be well built and was giving me a solid charge. I will follow up with a longer term review later.I contacted the seller with some questions, and they were very responsive and a pleasure to correspond with!

on a very sunny the most i got is 150 watt. I would buy another because no panel will ever give the amount of watts according to spec. The panel is good quality. My Bluetti generator fan turn on to cool the battery from overheating. Cooling take about 15 to 24 watt i guess.

The best I'm seeing from this panel, wattage wise is 130 watts. Definitely on the low side for a 200 watt panel. Price was good and shipping and packaging was perfect and it is a nice looking panel. I have another panel from BougeRV, 180 watts that solidly out performs this panel, unfortunately it was no longer available, so I thought I would give this one a try. Won't be sending it back because of the hassle but can't recommend this one it's mediocre at best.

I started off with 3, liked them so much I now have 10 plugged into my Ecoflow Pro. In full sun I did get the 200 watts. I now have 2 parallel sets of 5 in series. Was recently producing over 1400 watts at 150 feet of 8 gauge.

I installed these two panels on my Airstream trailer. Panels are well made and appear to be working well. The only problem encountered is that they only sent me one panel initially, but once I notified them of the mistake, they sent the second panel immediately.Very satisfied!
