Rated 4.1 out of 5 by 15 reviewers.
Rated 4.0 out of 5.0 by Time will tell I bought this product to replace an identical one that failed after nine months. The failed product was replaced under warrantee (now I have two). This process took a little over five weeks (!) since the manufacturer is in Montreal and the product must be returned across international boundaries. I am hoping I don't need to repeat that process. The product itself is excellent: the panel works well even when there is very little sun, like on a day when there are no shadows! The charge controller is very simple and does a good job of keeping my batteries topped up. It can be used with up to seven panels. I'm not crazy about the connectors used between the panel and the controller. I little warping with pliers makes them more reliable. I'm looking into replacing them with something better. I would recommend this product to anyone looking for a similar type solar charging system (used for keeping cellphones charged, some rechargeable lights and occasional computer use.). The "15W" specification is a little inflated. Another unnamed company sells this identical product as an "18 Watt" system. Since this charges a 12-volt battery with a maximum of 1.0 A per panel, 12-13.6 W would be a more honest number, since that's how much power you can actually expect to use. October 8, 2012
Rated 5.0 out of 5.0 by Easy installation! Awesome product! I put this on my RV and started charging my batteries right away. Installation only took an hour and I had to run the wires. Highly recommended! May 29, 2012
Rated 5.0 out of 5.0 by Worked exactly as promised I have a construction trailer that is designed to run off house power, or inverted battery power. This solar panel keeps the batteries charged, all the time, without having to plug in a battery charger. Makes my trailer, and its tools, solar powered. October 6, 2012
Rated 4.0 out of 5.0 by Perfect for my stored Motor Homes battery I needed something to charge my battery in my stored Motor Home and this looked like it would do nicely. It was well priced and arrived on time with free shipping in a very well packaged box. No broken or missing parts. You have several options to connect to your battery. You have clips to connect directly to your battery's terminals or you can use the included adapter to plug directly into the lighter/power outlet if it works with the key in the off position, and you can also wire it directly to the battery as well. Most of the connections are plug and play but not all. It comes with the regulator you need to keep it from overcharging. It has a very long wire so I just layed it on the roof and plugged it into my lighter outlet. So far it is working as advertised. I will also use this solar charger while dry camping as it will top off my coach battery during the day. July 9, 2013
Rated 5.0 out of 5.0 by Great Product I was currently using one of these same kits to help charge my battery on my tent trailer while I camp. It works so good I wanted to add one on, so I can now charge the battery in half the time, which is about 10 hours of sunlight. September 16, 2014
Rated 5.0 out of 5.0 by Great Little Solar Charger This is a very well built unit and came with several adapters for various connections to your load. The output is right as advertised even in low light conditions. Perfect for what we are using it for. March 18, 2014
Rated 5.0 out of 5.0 by it was perfect for my application We were camping where there was no available electricity and the solar charging kit with my battery and inverter kept everything charged nicely. I would recommend it to everyone. September 6, 2011
Rated 3.0 out of 5.0 by Replacement after 14 months This was a replacement unit. The original had shown reduced voltage after 14 months mounted in a safe location. Apparent water damage and washing out of the thin silicon layer. Barely attached wire. Construction is not substantial. October 15, 2013
