Rated 4.7 out of 5 by 7 reviewers.
Rated 5.0 out of 5.0 by Easy Peasy Installation The installation took about 20 Minutes including the 2X4 prep. I was surprised how easy it was. This was my first solar panel install. As far as the quality, durability and longevity of the panel....we'll just have to wait and see. It does look smart though. February 11, 2014
Rated 3.0 out of 5.0 by Holes don't line up The holes for the two hole pipe clamps in the back of the panel don't line up with the straps. You have to open the strap and it is still not enough. Can't easily safely drill the holes bigger on the panel. Worked so far otherwise June 26, 2015
Rated 5.0 out of 5.0 by Great The product arrive on time easy insulation, works great April 14, 2015
Rated 5.0 out of 5.0 by Super Easy Installation This solar panel was bought to power a dual GTO/Mighty Mule gate opener. The installation couldn't have been easier. Everything you need is included. The panel charges the two batteries for the gate so well that we get far more cycles than the manufacturer states. June 8, 2009
Rated 5.0 out of 5.0 by Solar Panel I had the 5 watt and it did not keep the batteries charged. Since I installed the 10 watt it works perfectly and do not have any problems with the gate. November 14, 2010
Rated 5.0 out of 5.0 by Great product! so far so good! We got the 10 watt because in the winter we might not see the sun for awhile and we might be going in and out more than what a 5 watt could handle. It was easy to hook up and has been working great. We have actually gotten more open and close functions than what was stated in one day. September 25, 2013
