Review: Not bad for the price - In case you wanted to know what a 30w panel can recharge your battery at, here is how you can figure out what the amps are when charging. Let's say you bought 1 of these panels. You already know that it is rated for 30 watts, but how many amps? Take the 30w ÷ by the volts which is 12v (battery) and the answer is 2.5 amps. Most battery chargers/maintainers charge at. I bought 1 to try out on my SxS for a trip to Arizona. Unfortunately for me, this one was working so well recharging my marine battery backup (I have 2 of these batteries for my lights) I purchased another 1 and hooked it up to the other battery. Now both batteries are charging at the same time when I am running around in the desert (and at home) and at night (depending upon how many lights I have on, the SxS headlights are separate from the other lights) I will have between 4 to 8 hours of battery usage longer if I use only 1. Then during the day, they are recharging. They are completely waterproof which is good because I did buy 1 and it was water resistant (not the same thing, it did stop working won't mention the product). I found out because I wanted to know how water resistant it was, so I left it outside during some local rain storms we had before going on my trip and that's how I found out the difference between water resistant to waterproof. I did the same thing with these and I had no issues yet. While on my trip we had very good and hard downpours. However I did bring my battery chargers (just in case) to help out if I had problems with the panels. During this part we had a storm move in and it was a gully washer of a storm. The storm lasted 2 days and at times it was pretty dark during the day so charging was hampered. If you ask me would I get another 1, "YES" would be my answer even as a gift. I hope this helps you, I am always trying to find ways to just get another panel but the 2 I have are doing the job. No regrets. 06/19/2025- I expanded my ability to recharge each of my marine batteries on my SxS and the main battery that starts the engine. I bought a "Y" with the same connectors and I got a 12awg extension cord with the same connectors and hooked up the battery under the hood of the SxS and 1 of the marine batteries and it charged both batteries plus was able for the green light on the solar panel to confirm it. It took about 3 hours in full sun, longer of course if cloudy. I did the same hook up with the 2nd marine battery but I bought a 20' 12awg cord to plug into the main battery on the QUAD RUNNER. It took a little longer to charge but it did. So now basically my SxS is self charging and is capable to charge another machine (provided it is set up to except the connection). Hope this update has helped someone that hates to wait for charging. I will still do the overnight charges. 08/15/2025 Update: I have bought #3 panel for the QUAD Runner but I have not been able to hook it up due to work, but when I do I will update this as soon as possible. Update 08/28/2025: I know that someone out there reading this will make a comment about this but I was so intent on the recharge part using these panels that I didn't realize that something else was going to happen. I know that I should have figured this out but sometimes I do have BRAIN FARTS. I was riding around in the SxS and I noticed that the voltage meters were increasing. I didn't disconnect the solar panel from the SxS battery so since I was driving around, the SxS was now charging not only the battery under the hood but the marine battery it was connected to with the panel. So now I have not seen any issues with this and when the SxS is off, the panel takes over keeping the batteries up. I thought it would ruin the panel but so far it seems fine. I will do another update on this after I get back from my trip to Arizona in November. Thanks for reading this, I hope this helps you. Update 12/01/2025: This has been a great test with my SxS and the 2 solar panels. Believe it or not, I never had to put any of my chargers on my SxS in Arizona. When I was done driving the SxS I would park it so that it would get the most direct sunlight possible until it was needed. 9 times out of 10 I would have both panels in the green. The panels had 3 colored led lights on the back where the controller is and the Blue light meant it was getting the right amount of sunshine and was working. The second light was Red which indicated that it was in the charging stage and the last light was Green which means that the battery or batteries was fully charged. Not very often did I not have Green lights on both before usage. The 3rd panel I bought was for the QUAD RUNNER and I still don't know how to mount it so it can do what I have done to the SxS yet. I hope this helps you with whatever you want to do with your machines. Have fun with it, I'm having fun learning what I can do with them. Maybe 1 day I may move up to a higher wattage solar panel and have more options or opportunity on lighting.
Review: Great solar panel - Use this to maintain my truck batteries on my diesel as it sits long term between travel. I love this charger. Even sitting on the dash through the glass. I plug it into the lighter plug and it works excellent.
