Very pleased with the little panel. Have it on the carport roof keeping the camp battery topped up.

Great price and delivered quickly. Seems to charge even on dull days.

I own a number of solar panels of various brands (most are very similar so shop by price for the size/wattage you’re looking for), and so far I’ve had really good luck with them. This one is no exception. These newer panels are more efficient, so they produce more power with a smaller size. This one works well for keeping a battery maintained using an inexpensive solar charge controller. I like to hook up jetskis, my boat, tractor, plow truck, etc to this type of setup as it keeps the battery topped off between uses.
Time will tell if this one holds up as good as previous panels. I’ll update this review as needed once it’s been out in the weather for a while.

Used to power Yeti power station for Ham Radio gear in the field, works great

Update: Ordered another.
Using to power my MIghty Mule MM317W. I have two gates, one running off a 5W GTO array.
This one seems to be similar quality and puts out twice the watts for 20% of the price.
However you have to buy a mast or make one. I bent a 1/2″ EMT tube to 45 degrees and used 1/2″ EMT 2 hole clamps. For my location, a more shallow angle would be appropriate to compensate for summer angles, but for as much power that is required, it really does not matter when pointing to the South.
I drilled thru the clamp and the mast and inserted sheet metal screws to keep it from twisting in the clamps. Has sustained 35mph wind so far.
I do not think Eco-Worthy should ship the wires stripped. Too easy to short out. I cut the bare ends off until I was ready to terminate to avoid shorts, and covered the array until it was connected.
Shipped in a thin un-padded bag. I hate that. Bad protection especially for glass. Fortunately the manufacturers box was adequate this time and USPS handled it with appropriate care.

las utilizo para cargar las baterias de los pastores electricos para ganado donde no hay posibilidad de enchufar a la red me evitan tener que cargar semanalmente en cargador algunas tienen dos años de uso y como elprimer dia

I bought two of these ad they appear to function ok. One puts out about 25% more current than the other but both are over an amp into a Battery Tender Solar regulator when exposed to full sun.
The aluminum frame seems ok but I would not rely on the edges to hold it on the outside of an RV in the direct wind. It looks like it is sealed well so hope it holds up to the weather.

Nice solar panel for 25w. You must get the solar controller to power up your battery. I’ve used a deep cycle battery for this application as it will power my off grid green house. Packaging could have been better as it came out of a flat box with no protection since it’s a glass front on it.

These are almost cheapest 10w panels on Amazon, but are surprisingly decent. I guess the technology is there that it doesn’t matter any more.
I was able to get full output and then some with non ideal placement (although it was a bit cold~12c and not rated 25C which boosts panel efficiency). From 2 panels in series and Victron MPPT controller, panels tilted at 30degrees (winter -favoring setup) and directly south, I was able to get 19-20W sustained even before solar noon (optimal tilt would be somewhere ~55-60 degrees).
If I were to guess manufacturer knows primary use of those is a simple PWM controller, which will lose quite a bit of power on conversion and oversized them a bit or it’s just quality mono panels + purely temperature effect. May be edge of cloud effect. In any case, on completely clear patch of sky – 19W sustained for long periods at bad angle is remarkable. Was hitting 20-21 sometimes.
Note that Vmp of the panel is 18volts which is insufficient to fully charge an AGM battery through MPPT so you need to have at least two in series. Which I did due to installation space constraints.
Remains to be seen how the panels will work in winter and few years down the road but so far so good.

I have two of these. One keeps the battery in the diesel truck. The other one keeps my homemade solar generator topped off.
My OC voltage is between 22 and 23 volts. That works well to keep 12VDC and 13.8VDC batteries charged and ready to go.
Good buy, 100% good panel, no defects.

Works perfectly, have it on my boat to keep batteries charged.

Have purchased this product years ago. Great buy for the money
