EF ECOFLOW 2PCS 100W 12V Solar Panels, High Efficiency Monocrystalline PV Modules, IP68 Waterproofing, Ideal for RV& Marine Rooftop, Farm Battery, Power Kits & Ecosystem

Very close to the advertised wattage. I have 3 of these 100w panels (300w) and have seen upwards of 280 watts. They sit atop my small van and charge a 100ah lithium battery.

I purchased these back in Nov 2022 because they had a great sale. I finally purchased a powerful solar power station and got the opportunity to use the solar panels. I connected both 100-watt panels in series and connected them to my power station. I was expecting to get about 150 watts of solar power but was very surprised to see a peak of 210 watts and a very stead 190-200 watts at 3PM. When I snapped the picture, it happened to be at 189 watts due to some partial clouding.What I liked:- Great packing, great quality, heavier than another 100 watt panel I bought but much sturdier- Fantastic efficiency!- Easy to use with the MC4 connectorsI simply connected both panels in series and used a MC4 to Anderson cable to plug-in to my power station. I couldn't be happier with my purchase and I will definitely buy more ECOFLOW panels when I need them.

Needs DIRECT constant sunlight to trickle a charge into the compatible storage device. If not...charges 8% for an entire day. That will charge a cell phone or 2. But not a lamp for hours...or WiFi for hours. I'll need to mount to my roof in a more sunny location...buy additional cord for added length. To park in a sunny spot at a camp site with these on the roof. Yes. But now your camp vehicle is cooking in the sun.

High quality panels, but you have to get them at a good price.

I received this solar panel on the third day. He's not two separate panels, he's packing two into a cardboard box, which is obviously by special design. I am a big fan of ECOFLOW, I ordered a complete set of 15KWh Power Kits for my RV on their official website not long ago, it is a very surprising product, they integrated the previously complex independent power system into a simple, beautiful and high-performance power system through their ingenuity. Obviously, EcoFlow has been at the forefront of the new energy storage industry. I had two solar panels before, but it seems like I can't get enough of my Power Kits now, so this time I bought two more from Amazon instead of the official website. Because the official website is a little more expensive than Amazon, because they sell combo with 2 brackets, I have enough brackets so I choose cheaper Amazon products. EcoFlow's 100W solar panel looks really cool, and the whole body is black, which echoes my black RV very well. Much better quality than my previous aluminum framed solar panels, at least they don't look that cheap things. I installed the solar panel that afternoon, it was really easy to install, because it has pre-drilled holes in the back, you just need to screw the Z Brackects on your roof to fix it, then connect the solar cable and you are done, Of course I chose parallel connection. It was sunny the next day and observed the solar input power at noon, I remember that on a sunny day, my two old 100W solar panels were getting 125W, now with four 100W panels, I was getting 285W of power. This shows that the EcoFlow's solar panels are giving me 160W, which is 35W more than my old solar panels. Seriously, it's shocking because the new solar panels are about the same price as the old ones, which is so worth it to me. If according to the public perception 1W is worth 1dollar, I think I earned 35 dollars directly. All in all, I will always support EcoFlow, they don't seem to be interested in making money, they are really interested in creating products that benefit human life. I have to say they are the Apple of energy storage.

Best solar panels I have..

Have a Ecoflow Delta mini, and always bring it when going out for a car camping. Plan to make a portable solar panel suitcase with the 2 pcs rigid panels.The item was packaged well with good padding. The real panel was measured about 38 3/4 by 23 1/4 inches. There are 2 mounting holes on the short edge, at 4 1/4 and 19 inch from one end. 4 holes are on the long edge, each at 4 1/4, 11 1/2, 27 1/4 and 34 1/2 from one end. There are no brackets included in the package, which requires to be purchased separately. A Y adapter is needed if you plan to parallely connect the two panels. Tested the two panels separately around 3pm under direct sunlight, outside temperature around 73. Both panels perform well, with about 80-83 watt output charging the Delta mini generator. There was a peak at 85 watt for a few seconds at the beginning. Both outputs around 65-68 watts around 4pm , and 40-45 watts around 4:30pm. I am sure the output would be higher if tested during the noon time. I noticed a light scratch about 2 inches at one of the corners on one panel. It is very light and hard to notice, and does not affect any functionality. I would suggest carefully checking the glass during unboxing.The panels worked well with the Ecoflow generator. Can't wait to make the suitcase with these panels, the size can easily fit into my SUV.

These are easy to install and appear to be very well made. I have bough 3 sets so far!
