ECO-WORTHY 25 Watts 12V Off Grid Solar Panel SAE Connector Kit: Waterproof 25W Solar Panel + Adjustable Mount Bracket + SAE Connection Cable +10A Charge Controller for Car RV Marine Boat 12V Battery

I had been using a mains battery charger to come on for an hour each day to charge the battery of my Jaguar XK8 in the garage, but didn't like the idea of it, so looked for a solar alternative. Have now used the panel for three weeks and it is superb, although we have had little sun, the battery shows a constant 12.8 volts all the time. The charge panel shows a solid green led, showing its charged. I put it onto a flat battery and the led blinks as it charges until it reaches 12 volts, then holds it at that. On the down side, the instructions are very basic, and the led unit, I had to put Velcro on the adhere to the wall as it does not have a fixing itself, and the panel itself has no holes so had to make my own brackets, but in operation its superb.

I now own two of these and I still can't get the eco-worthy controller to show only LED 1 which indicates a sealed battery. It always shows LED one and two. The directions are confusing or inaccurate. This controller cannot recognize a battery for what it is. Again I have purchased a small MTTP controller that has no trouble whatsoever identifying what my battery is. ___________________ I gave this a five stars because it seemed unfair to ding my review over the fact that the controller that came with it to proved to be unworkable. After 6:00 or 7 readings of the directions I was unable to make the controller recognize and AGM battery. The AGM would go under sealed battery but it kept staying on two lights which meant that it was either a lithium battery or a gel battery. You can't run an AGM battery on anything other than sealed or AGM. For that reason I had to move to a tiny MTTP controller that worked instantly and made it very easy for me to link the battery with the solar panel. I think that it's a very nice system and I'm using it to trickle charge and AGM battery over winter. My plan is to buy another one of these and set it up in the same way to trickle charge over winter a typical sealed battery. Here is something you'll really love. I set this up approximately 24 hours before hurricane Helene hit the mountains of Western North Carolina. The solar panel was set up on a 4x4 post with a 2x4 support that formed a cross. The cord on the panel is very long and makes connection into a outdoor storage cabinet very easy. I then connected some green covered ground wire to a 4 ft piece of rebar next to the 4x4 post. I then stapled the ground wire such that it was not going to pull on the solar panel. The result was very pleasing. It's survived 40 to 60 mile an hour winds. I do hope to figure out why I was unable to program the control panel that came with it.

This appears to be good quality for the price. Very satisfying after plugging it in to see the included controller light up and start charging. I bought for a private aircraft to keep the expensive $800 aircraft battery topped up during the cold weather. It does recommend not placing it behind a window however I placed it flat on the dashboard in the windshield and it seems to work fine, maybe not optimal but it was charging and I don't have to worry about it being damaged in wind etc as it will be unattended in my case. The included alligator and permanent battery connections are a plus as are the cable lengths which were more that adequate for my use. I would recommend and if I have any issues - will update

This was added to a electric troll motor battery box. It works wall and keeps the battery charging throughout the day and when not in use. It's not the fastest charge, but over time, it does help keep things going.

I bought this Solar Panel kit to maintain the battery in a zero turn mower I use once a week or so. Everything I needed came in the box. Panel was simple to install on the outside of the mower shed. I drilled a small hole to run the cable from the panel to the charge controller. The only extra item I bought was a 4 ft. cable with a sae to sae connector for the mower battery. So far everything works flawlessly. Battery stays charged up. I think this setup is better than running an extension cord and battery charger. I like the idea of green power. Added a small stand for charging extra batteries.
