Topsolar 100W 12V Solar Panel Kit Battery Charger 100 Watt 12 Volt Off Grid System for Homes RV Boat + 30A Solar Charge Controller + Solar Cables + Brackets for Mounting

Great solar panel kit, is currently working well on top of our RV. I bought it knowing that the roof roofing mounts holes didn’t lineup, but I was able to easily just drill through the aluminum on the panel so it was no big deal. Would buy again.

It’s pretty easy to install!

Wired 2 in parallel to charge all the batteries in the tractors and buggies works great seems to be of good quality can’t complain at all.

Works great but over time after it was set to 24v set up... I can't get it to change to a 12v set up now. I have already tried many different things to change like unhooking the battery and solor panel and pushing the 3 buttons in different sequences and still can't get it to change to 12 volt any ideas??

I bought this kit to strap to the roof of my excursion, which has about a dozen lights that drain the battery every time you open a door, and consequently will kill my battery if left unchecked. This setup isn't ideal for a smaller vehicle - a flexible panel would be better suited, but my roof rack has plenty of room for the full-size panel. I bought the 'RV kit' with plastic corner pieces that mount to your application, and they would indeed work well on a larger RV roof. You won't get amazing performance from a single 100w panel, but even on cloudy days it'll hit 13+ volts with what amounts to a trickle charge, which is more than enough to keep my battery healthy. The actual installation wiill depend on your application, but you can't really get it wrong - the plugs and included wires are black and red, and everything just plugs into the voltage regulator. You'll need to route these wires to your battery somehow, and honestly, the included battery leeds are fairly long but you might need to get longer cables because they're not really long enough to get creative with your wiring. But since it's a low-voltage DC system, any decent copper wire bigger than like 10 guage should be enough to work. YMMV but this little kit is simple and spare, there's not a bunch of extra crap to worry about - you just mount the panel and plug everything in. Depending on your needs, it won't take long to get it all working. A single panel is not enough to run a large power inverter, but these panels are basically infinitly expandable with the right wiring, so once you have the 20A regulator, you can add like 6 panels without needed to upgrade. good luck, and may you have sunny skies out there!

Perfect solar panel for ur buck great fitment on top. Easy to wire and install

Charge controller set screw stripped just loosening it up. Panel seems decent and it does charge, but I had to tape negative battery cable into place. Ordered another controller direct from China for $3. Company contacted me and offered a “Full refund” it I responded with “Full Refund. So I did. Then they said couldn’t and offered a $10 refund. $10 doesn’t even cover a new charge controller from them. Buyer beware. Went from a 2 stars to 1 star. Pretty pathetic customer service.

Got this to use for our camper. It works even better than we expected! Changes fast and still works pretty decent when it’s overcast. So far we are very happy with this brand. They seem like great durable quality and arnt too big or too heavy which is great for our camper. Easy to install as well. Got it working in less than 30 minutes.
