For a 50w panel, this works well as a trickle charger for a 12v battery. I have a deep cycle marine battery that I use to power, along with propane, the needs of my 18′ camper trailer. The solar panel is light & small enough to be mounted pretty much anywhere and connection to the battery is simple. I had an issue with the controller charge light erratically going off and their customer service promptly sent me a new one.

We are using this panel for our 5th wheel storage. It’s a really good size. Works well.

This arrived a day early and has very clear instructions. Everything you need to set up a solar RV battery trickle charger is in the box, except the sun, and if you’re lucky there will be plenty of that in the sky. This is plug and play and seems to be working great right out of the box. Hoping it holds up for the whole season, and into the next!

Output is about right for specs and solar conditions (37 watts, later in the afternoon, good sun, no clouds). The controller was a total no-go, however. It lit up, but didn’t pass any current AT ALL. Uses SAE connectors which aren’t my first choice, but I have adapters. For the price, it’s a non-starter. With the current 50% off coupon, it’s a borderline okay deal for just the panel. Would not recommend. Would not get again.

This is a great all-in-one kit for charging 12-volt batteries using plentiful sun power. You get the panel itself, some basic mounting hardware, a charge controller and the cables, all in one box.
Under full Southwestern US sun this gave an open circuit voltage of 22.6, with an amp current of 2.37, which given the formula amps x volts = watts comes to 53.56 watts, slightly higher even than rated. Just under the shade of my porch while I was first hooking everything up I got 15.6 volts, so this should do at least some good even on a day with scattered clouds. The aluminum frame of the panel is light, but very sturdy, and the thick glass over the cells themselves seems like it should keep them safe from the elements easily.
The charge controller is a bit basic, it has no configurable settings or voltage display, you just get three colored LED lights to show you the status, but it is at least an MPPT-type controller. Those are supposed to adjust current dynamically to give a more efficient charge than old style PWM controllers, and while I can’t do a direct comparison, since my PWM controllers are from different manufacturers, I can say that this controller seemed very efficient. The first time I set this up to test it charged my 7Ah LiFePO4 battery from dead to full in just four short hours.
The mounting hardware that comes with this is only for screwing it down flat onto a rooftop or equivalent, but it is all sturdy metal and made to last. On my shed in the backyard the size of this fits really well. With a few 12V LiFePO4 batteries I keep swapping in to charge and a small 12vDC-120vAC power inverter I can easily recharge all of my yard and power tools right in the shed as needed, without having to run an extension cord across the lawn. It’s a real convenience! This would also sit nicely on the luggage rack of a van for camping, with some hardware to accommodate that, and I’m keen to try that with another of these later this summer.
The panel gives every bit of power it is rated for, and under really intense sun it does even better. The charge controller, while basic, is fast and does the job well. This doesn’t have a rotating bracket, but if you’re direct mounting flat to a rooftop, the included hardware is plenty good enough. Considering you get everything you need in one box, and how well it all works, I wouldn’t hesitate to recommend this a moment. I’m very happy with it!

This panel and charge controller was $124.99 at time of order. For 50W, that’s very high. I tested it and it performs well, so at that power, it’ll certainly keep a battery topped off and it’ll even keep you in full charge for the day, if you’re running something like a 40W portable fridge/cooler. It’s not what I’d really consider to be portable, as there are so many lighter and flexible options out there. When you get over a hundered bucks, a lot of options open up, including pairing a nice flexible panel and PWM or MPPT charge controller together. The output from the charge controller was high, at 16.3V. It was a bit overcast today, so hitting the higher voltage mentioned in the manual seems reasonable.
I do see the price has been dropped by 40%, which makes it much more reasonable, but I’m rating it at the value it was at the time I ordered it. Even at $77.99, it’s just an okay deal and I’d advise spending a hair more and getting something nicer.

I bought this 30W solar panel and charger to use on a car that sit on the driveway and isn’t often used. I’m happy with it so far. It’s a good option for keeping my car 12V battery charged, and if I need, it could also be used on RV or motorcycle…etc
Here are some things to consider: Easy to set up: The solar panel system comes with all the components you need to get started, and it was easy to figure out how to hook everything up.
Durability: The frame is made of aluminum and the solar panel looks and feels well made, and is also covered in tempered glass, so it should hold up in bad weather.
Trickle charger: It will keep your battery topped off but it won’t recharge a completely dead battery quickly though.
Overall, I think this is a good solar panel charger for the price. It’s easy to use, seems durable, and it’s a great way to keep any 12v battery topped off with free renewable energy.
