The upgraded controller is simple to use and gives you peace of mind that the battery won’t overcharge. Even on cloudy days, it still provides a steady trickle of power. I’ve used it on both my RV and my boat battery, and in both cases it kept everything fully charged and ready to go.

This is a great solution if you want a reliable maintainer for a car, boat, motorcycle, or RV battery. It just works. Highly recommended.

### ⭐⭐⭐⭐⭐ Easy to use and install
*by J***A on November 4, 2025*

UPDATE 1/11/26: It has been over 2 months since I installed this solar charger for my lawn tractor battery and I am still very impressed. I did have to install some extra wire length to reach my lawn tractor battery, but that was not the fault of the solar panel and was relatively easy to do. What I did do, that has been a big help, is glue magnets to the back of the controller, which now keeps it from hanging or falling off the lawn tractor. The controller, with only 3 lights, is easy to read and quickly assess if it is charging and if the battery is charged. Even on cloudy days, this solar panel is charging! I'm considering getting another Solperk Solar Panel kit for my farm tractor stored in a "non-electrified" barn. So far, I really enjoy not having to worry about a discharged battery when I want to use my lawn tractor! I've had no problems with this solar panel and controller! I purchased the SOLPERK Solar Panel Kit 20W 12V, Solar Battery Trickle Charger Maintainer to charge the battery on my lawn tractor, which sits in a shed without electric service. So, the battery didn't seem to maintain a full charge between uses and sometimes wouldn't turn the engine over. I installed this yesterday to help maintain the lawn tractor battery in full capacity. The installation is pretty simple, with a bracket to hold the solar panel provided. Just a note, the bracket can only be mounted in a horizontal position to support the solar panel and provide directional control for the panel to face the sun. Installing the bracket vertically, will only allow the solar panel to be turned left and right and will be perpendicular to the sun if mounted on a vertical post or wall. There is about 8' of wiring to the controller which connects to the panel. The controller requires no programming by the user. Connect the controller to the 12V battery (battery clamps provided with unit) then plug it in to the solar panel and three lights will tell you everything. The blue light (on top of the others) tells you the panel is in the sunlight and providing normal voltage. The second light is red and will tell you that it is charging the battery. The third light (green) appears only when the battery is charged, which means the battery has 14.2 volt charge. It comes with a set of wires to actually screw down on battery posts. So far, the unit seems to be working and has charged my 12V battery fully! No need to remove the connections when charged, as the controller will prevent it from overcharging the battery. I don't know about longevity of the product, the controller is supposed to be waterproof but I keep it inside with the lawn tractor. Other than keeping the solar panel clean with a damp towel, and the battery clamps clean, there isn't much more maintenance required, the instructions say! So far, I do like the unit and being able to keep my lawn tractor battery at full charge! Easy installation!
