MEGSUN 100 Watt Monocrystalline Solar Panels are Designed to Provide 12 Volt, 22.8% High-Efficiency Power to Various Off-Grid Applications, Such as RV Boats, Batteries, Home Roofs, Campers, and More

The media could not be loaded. UPDATE-added a second panel using 2 Y-splitters, keeping positives and negatives together, and a main pair out to the ecoflow. Consistently getting about 125 watts total output. The first panel put out about 90 peak. Even wiring the panels in series to get higher wattage didn't work. Stuck at 125 with clear consistent hot sun. The second panel has hazier glass with a bluish tint. The first panel was clear glass and "glittery" wiring underneath especially in the center section. New panel looks hazier with no "glitter" effect to the circuits underneath. Almost wonder if I got a 50 watt panel instead of 100. Or a not so great panel. I plan on going to 500 watts total so this step really didn't help as expected. Wary of ordering a more expensive panel.Bought my first ever solar panel to attach to my new ecoflow delta 2. Too many power outages at our place and I can't afford a generac system. And those have issues as well. Went with a ecoflow electric generator. Excited at the chance to run solar without spare batteries and inverters and an electrical wiring phd and a spare shed to store it all.I simply bought this panel. Didn't know what I was doing. Bought the universal mounting bracket kit from renogy at HD for $10, put a couple fresh 2x4's on the fence rails in the backyard, and screwed it up with drywall screws. No tilt, no azimuth calculator, no elevation. Just a place that gets a lot of hot sun. I did need some extension cables to reach my delta 2 inside on the other side of the wall. The run is about 15 feet. Apparently solar cables have very little loss. Amazon has all the extension cables. And if you have an Ecoflow, they only give you the solar adapter if you buy their grossly overpriced solar panel kit. Don't do it. Just get the same adapter from Amazon. Works fine. I ordered one from ecoflow and it took over 2 weeks to arrive. Same with ebay. That stuff takes weeks to arrive from China and it's frustrating waiting. The adapter has a yellow solar plug on one end that goes to a red and black line. They just click together. Match the colors. So simple. Plug in the panel, plug in the yellow end to your ecoflow and watch the watts come in. So satisfying. This panel for me hits about 88 watts peak. The ecoflow controls the battery charging all automatically. That's with the panel just screwed into the fence. No angle no nothing. Sturdy, but flat. I'm not making a lawn sculpture out of a solar setup. Simple and easy attach it to the fence. I plan on buying another panel soon. I have the adapter cables to add a second one. My generator supports 500 watts solar so it will handle 5. Don't buy the overpriced ecoflow panel kit. Buy a couple real panels and save yourself $750 bucks.

I had been buying another brand but picked up a couple of these to try, the price with the coupon was really good. I am not disappointed, power output meets all expectations. I tested power twice using a 3 ohm dummy load which is pretty close to optimum. On a bright sunny day I got 18.15V which yields 110W of power. Tested again on another day that was slightly cloudy and earlier in the day and I got 16.8V ... 94W. I wanted to do another bright sunny day test but we haven't had one since when I was home, more to come.For construction, they seem well made, similar to other solar panels. I did receive one that was broken, they took care of it no problem. The replacement was fine and so was the next panel I ordered. 5 stars.Update a year later, still running great. I had a tree fall over the roof, right above these panels. I had to gut it off piece by piece. I tried to protect the panels but 2 large pieces fell bad and landed on them. One piece hit very hard. The panels didn't break, the glass is fine, they still work 100%. 6 stars if I could give them.

I was looking for a set of solar panels to power my Ecoflow mini solar generator and these fit the bill. I am running them in series to meet the amps limit. They are light weight enough I can move them to catch maximum sun but seem to put out good power. The price was really good and they seem to be well made. Right now I am using them as portable panels, but plan to a fix them to a patio cover later. I think these are good panels. Edit: Went to disconnect one panel to attach to a longer cable and cannot get the female plug to disconnect. This is a problem.

I just got back from a 4650 mile trip to off-grid Wyoming and Montana. This recharged my Vtoman Jump 1000 to 100% everyday. I only had one day of rain and it was not a problem.I mounted it permanently to the roof of my 1996 Toyota 4runner and it filled the sunroof footprint perfectly.

Very fast shipping. I'll check the specs when we get some good sun down here in FL--hurricane cloud flow still creating hazy conditions when the sun briefly pokes through. The individual cells are relatively wide, as compared to other panels of this rating, so the current should be up there. I mainly bought this panel to match the sizes of an older panels I'm using--adding to the bank.As an update on 9/2/23, under full sun, and with the panel heated up to over 100 degrees F, and ambient around 90 degrees F, the panel open voltage was 21.3V and short circuit was 4.18A. That works out to be close to 90W power which dang good for a 100W panel on the market these days. A MPPT controller will like it a lot.

Just wanted seller to know this arrived in perfect condition. I am waiting for a sunny day and the proper adapter for cords (sold separately) to write a proper review of it's functionality but I have no doubt it will be perfect for what I need! Thank you for the coupon, fast delivery and free shipping too❤️+Update 7\16- Works GREAT! Highly recommend 👍🏼

Great panel for small solar projects. Well designed mounting frame and electrical output voltage and current met or exceeded website specifications.

Added another 100w on my RV roof.
