PowerECO 12V 100W Mono Solar Panel (Panel Only)

I have 4 other 100 watt solar panels which are made nearly the same. One panel puts out ever so slightly higher current while the other puts out ever so slightly more voltage. So mathematically, they're nearly identical in terms of wattage output.My old 100 wat solar panels measure 26.4" x 40.25" and this new PowerECO panel measures 19.5" x 42.25". So in terms of square inches, my old solar panels took 1062.6 square inches to put out the same amount of power that this PowerECO panel puts out with only 823.9 square inches. That's almost a 25% size reduction for the same amount of power. So you could fit a 500 watt array in the same amount of mounted space as a 400 watt array with these panels. And so on as you scale upward. Usually, larger panels are more efficient in terms of wattage put out vs how much space the panel occupies. These 100 watt panels approach the larger panels in terms of real estate vs power output.So long story short, you get a lot out of a very moderately sized panel. If you have an existing array that uses 100 watt panels and it's time to change them out for new, or if you're looking to build a smaller array or even a portable setup, this panel has fantastic output for the size. And the cost is on par with the less size efficient panels. There's nothing not to like about this nice little 100 watt wonder.

This "PowerECO 12V 100W Mono Solar Panel (Panel Only)" works as expected. I mounted this on top of my trailer and it worked fine for a while now. Comparing to another similar one that cost more, the construction and efficiency of this is fairly comparable. I do see some wear on it when setting this up and exposing it to the element 24/7/365, but it is what it is, as long as it continue to work and not just die on me, I call it good.Thank you for reading this review, I hoped that this review is helpful to you in support of your purchase decision.

I wanted to power my patio lights and garden lights from a solar project. So, when this became available, I ordered it. Here is what i found:1. This is a decent panel that produces between 300 and 500 watt hours of energy on good days. if it is cloudy and rainy, figure about half that amount. The problem is that in order to produce what the panel is capable of, you need to track the sun and maintain the angle of incidence for max production.2. This easily connected to my charge controller, deep cycle battery, low voltage photo cell and lights. Since my yard lights draw only 12 Watts and my patio lights draw 4 when on, the system is able to maintain the lighting without problems. My system is on about 12 hours a day and if you calculated it with the patio lights on all the time, the system consumes about 200 watt hours of power and most of the time the solar panel returns more than that. On very bad days the system almost returns enough power, but when it is that bad, I am not on the patio and so that eliminates 40 watt hours of power and puts the system back in the range of what the panels can supply. My deep cycle battery is capable of supplying power for several days without any charge, so the system is good to go!!3. The aluminum frame makes it very easy to connect this structure to a roof or other mount.I am pleased with the result and so I would recommend the panel if you have need for such.

This review is for 100W single panel.The build quality of this panel is very solid and weighs about 14 pounds. This panel is heavy to pack and carry around, but I am still planning to use it for my upcoming camping trips. I know it is silly to carry this bulky and heavy panel, so I might put it on the rooftop of my SUV. What I want from this panel is simple: Charge my portable devices and battery packs (2x 300wh LiFePO4), and run the 12V cooler while connected to the battery pack. My testing so far shows that this panel is adequate to meet my needs. I was able to recharge my battery pack fairly quickly under the direct sun during February in the Northeast. Theoretically, in ideal conditions, I could almost fully recharge both of my battery packs in one day, but for now, I am satisfied with what this panel can do. My test measure shows 4.33A at 22.4V at around 11:30AM (45 degree angle, direct sun) and that’s pretty close to 100W. The module efficiency is 18.69%, according to the enclosed data sheet, and I know there are panels that have more than 20% efficiency these days, but, hey, $0.89 per watt is not bad for now. Overall, this panel works well for my needs, and I see the potential if my project expanded to bigger and powerful settings.

I am looking to get 10 solar panels and putting them on top of my shipping container to power the interior of the thing. I already have the setup inside so I just needed to create the outside part. So far this has been the panel I am going to use. It is skinnier and longer then panels I have used before, that being said I can fit more of them in the space I have. This is important to me and will actually allow me room for a few more panels if I want.The panel packs a good punch. I live in the desert and I get a lot of sunlight. This panel has a very nice output and I am please at how it works. I get a great percentage of use out of it and am happy that I have had the chance to use it.If you are looking for a nice panel for a project or just to use, look no further, this is the one. I have had no issues with it and it has stood up to some pretty harsh winds.
