Rated 5 out of 5 by Excellent panel I installed two of these panels in parallel with a flat mount on the roof of my travel trailer. I live at N41 degrees latitude. In this configuration I've seen almost 9 amps output through the Coleman 30 amp digital charge controller. I just finished a week long camping trip and even with running the furnace up to three hours per day, never had to run a generator. I plan on adding a third panel for a bit of extra capacity. These panels are well made, stout, and put out the power. I shopped around and for the warranty(Make sure the brand panel you get does not exclude mounting on vehicles or boats.), price and value, these panels from Home Depot are hard to beat.

Rated 5 out of 5 by Better than expected! First of all I am no electrical expert and know even less about solar. This started out as a trial project with a small kit from an ultra discount tool store. Like the old saying goes I wish I knew then what I know now. Discovering these solar panels from Home Depot quickly turned this into a serious hobby. I bought one of these to try it out and am so happy with it I cannot wait to buy a second and eventually a third one. As you can see from the photos I framed this to easily accommodate another two of these. FYI, these do not come with mounting hardware. However, Home Depot sells hooks that have a squared bend as opposed to a rounded bend which work great for mounting these to wood or a similar material other than steel. For those just starting out I would make a few recommendations. If this project has any intentions of becoming a serious endeavor get a pure sine wave power inverter. I got a modified wave and wish I had known the difference basically "clean" current without a lot of electrical noise. Also, go with these panels as opposed to the "small" kits and at least a 30 amp solar controller. Also for batteries you want the deep cycle batteries as opposed to standard car batteries. You can learn a lot from Youtube as well, I did. Hope this helps! September 17, 2013
Rated 5 out of 5 by I'm very pleased with it I have wanted to do something with solar energy for a long time and this panel is my start. I built a stand for it from PVC tubing (also from Home Depot!) and put it on my deck. The wires go into my house where the batteries are. I made room on the stand for another panel to be added in the future. I am charging two 50 Ah deep-cycle batteries with it using a Morningstar MPPT controller. BTW, the documentation that comes with this panel recommends use of a MPPT controller. I also have a modified sinewave inverter and I am determining what will run on it. My microware oven likes it, my clothes washer does not. This setup is to learn about solar energy and have some emergency backup power. I have a generator, but after the recent hurricane that hit the East coast gasoline was hard to get. I would at least have some LED lights, be able to recharge some things and do a little cooking.

Rated 5 out of 5 by Seems to work The Michigan winter isn't the best time to evaluate this panel, but it does give out electricity when the sun shines. I haven't been able to get 5.4 amps but I have received 4.5 amps when the sun shines directly on it. On cloudy days I get perhaps 1 to 3 amps, and if it's really cloudy, less than 1 amp, to zero. Very well built, and I'm satisfied enough to purchase more. I bought three so far. I don't have enough panels, or room for them to significantly reduce my electric bill, but maybe the summer Sun will produce better results. It's more for fun then economy. I'm not putting them on my roof, I'm placing them in my windows. If I move to a warmer climate they'll come with me. But the price of these panels are better than any others I've seen out there.

Rated 5 out of 5 by Worth more than the cheapo versions After looking at PV panels at a discount tool store chain, I decided to go with this one. Glad I did. Good solid construction and quality cables with MC-4 connectors are very much above the quality I perceived in the other panels. I drilled into the frame to mount a half a bed frame with wing nuts. This served as an easy ground mount that is adjustable and stable on the sand of Assateague, MD where we do much of our dry camping with my RV. Worked great. I used a cheaper Sunforce 10amp charge controller rather than the type Grape recommended. Just had to attach MC-4 connectors to the controller to make it an easy hookup. September 1, 2012
