SOLPERK 10W Solar Panel，12V Solar Panel Charger Kit+8A Controller，Suitable for Automotive, Motorcycle, Boat, ATV, Marine, RV, Trailer, Powersports, Snowmobile etc. Various 12V Batteries. (10W Solar)

Bought this as part of an outdoor solar-powered lantern project at my home, to charge a 20 AH battery. I mounted the panel permanently on the house sloped roof but had to modify the bracket to do so. As other reviewers demonstrate the bracket does work well for portable use but could have been made more useful if the manufacturer provided a few more holes. That said the cabling setup they provide is complete and useful for a quick and/or portable setup. I can't tell if that cable insulation is UV stable so long term it might break down in sunlight. However as one of the photos shows a sliding cover conceals the panel wiring so I was able to connect cable having better insulation.Another photo shows the panel, cabling and controller under test with a 12 volt DC candelabra lamp -- I guess this is the proverbial "solar powered night light" ;-)Although the provided controller works well as intended, I ended up using another one that has additional features more useful for my application.

Plug and play keep my battery full durable panel

I have not had the solar panel long enough to evaluate whether it can successfully maintain a 12 deep-cycle battery which powers an electric garden fence.However: The solar panel seems heavy for the rather flimsy mounting bracket. The package arrived with only 2 mounting screws for the panel-bracket's 3 holes; there were no screws provided to mount the controller (needs 2). The panel attaches to the mounting bracket with two small machine bolds and wing nuts. They allows the panel to be angled for sun exposure. I worry that system will be sturdy enough to withstand significant wind.

I purchased 2 of these, one for my generator and one for my boat. I have a different controller where I can monitor the actual voltage, but connect it to this panel for both uses. The panels are about a year old. They are mounted outside in the weather and have worked well. For my generator: it has kept my gel battery topped off and have strong starts every time. For the boat: It has supplied enough power to keep my 890CCA battery maintained during the winter and when the boat is not in use during the season, I have kept it plugged in and maintains a full charge. Given my boat battery is fairly big, this panel has worked fine. When I place my battery tester on it the tester confirms a 98% charge after winter. Pretty impressive considering the size of the battery and only 10W out from the panel. The panels get direct daylight for about 5 hours a day and then are in shadow. The controllers show charging still in the shadow so direct sunlight is not exactly needed but if you want to maximize your capabilities, I'd say make sure they have enough direct light for at least 1/2 of the day. Otherwise, the shade doesn't appear to hurt it any. Cloudy days still produce a good charge. Going to purchase another soon for my father's new generator that I am going to buy for him.

This is a very well made solar charger. The only problem I had was that the polarity is backward from the other one I have. My bad for having assumed that the same connector would have the same polarity, but I guess IEEE standards don't trickle down to this level of engineering. No matter, once I reversed the polarity of the solar panel wires connected directly to the battery on my RV everything worked like a dream. It's a good value and should add years of life to my RV battery. I would recommend this unit if you're looking for a weatherproof outdoor-rated solar-powered 12v battery trickle charger.

The media could not be loaded. This is my second solar panel, I like it better (so far) than the other one I own for 3 reasons: long wires, can be placed in a wall (which I will do when I came up with a place for it as well as a plan for the wires), and (my favorite) the passage box that indicates if it is charging or not (I had to use a voltmeter, but mine is not always working perfectly so having this is great).It looks nice (as most solar panels honestly), and seems very resistant. I will definitely place it on my wall when I figure out the best place for it, I now keep it in my pool area where there is almost always sun light.Oh! It comes with a manual, my first solar panel did not so I had to figure things on the internet. And also comes with the necessary things to fix it on a wall if you want to.

I bought it this April because of could in case of a power outage, I finally put it all together 2 months ago, one day my battery dies, the controller shows yellow light charging. But it is really not I test the voltage that it is trying to charge it is zero from solar.sure it powers light saying charging. but zero charges. I move solar still nothin', maybe bad wiring or maybe bad solar panel. something. I suggest buying all things you need and test them right away. I got a bad one, and I m out the money. NO tech number, sure it says tech support, but it's all lies, I search google, amazon all over for the last 2 months, I decide to call it quits, and write this bad review. I am out 65 dollars, and wasted time searching and putting it all together. I suggest trying other companies they show a tech number and have a website or something to help people, I feel this is all made up and I bought garbage. Well, lesson learns 65 dollars wasted, and over 10 hours trying to get it working and searching for help. But there is no one to help. So give up like me, and do not buy this product, and found a company that has a website and a tech number.Can you send a new one? It never charges fast enough I think the panel is bad. I would like to try a new one. Please send to 306 Dawes st, WI 54901

lo compre para alimentar un sistema de alarma, funciona a la perfeccion cargando una bateri de 12v 10A, facil de instalar, 100% recomendado
