Rated 5.0 out of 5.0 by Works Great! I am very pleased with this purchase. Couldn't keep my battery charged for my electric fence and this solar panel is doing the job! June 10, 2015
Rated 5.0 out of 5.0 by Great Panels I can't believe they are out of stock! I was going to buy 5 of them to finish my solar array on my house. Guess I have to go some where else. They are very easy to install. Mine are on the roof and don't forget to get the Z Brackets for mounting them on the roof as mine are . Great panels. Have had mine for 1 year and they are still cranking. They don't put out that much amperage. The most I have seen is 14.4 amps with 3 panels. The max is 5.65 amps each. This is really good as I haven't had any problems. And they say the cooler they are the more amps,not here.I live in Pahrump,Nevada and they put out less in cold weather and really go up in the summer. March 7, 2015
Rated 5.0 out of 5.0 by Great quality Sturdy-good quality- Grape Solar has a good reputation and is mostly why I bought this unit, price was good also. May 27, 2015
Rated 5.0 out of 5.0 by 12 volt project The panel arrived at my residence reasonably quick and in good condition. The panel is keeping my deep cycle battery charged .The battery is tied to a 12 volt pump used for watering from my rain barrels. June 1, 2014
Rated 5.0 out of 5.0 by meets or exceeds specs, good price/ watt I made a foldable, portable, solar charger for my Airstream with these. Added a charge controller, fuses, and connected all with removeable Anderson power poles. Worked great February 10, 2015
Rated 5.0 out of 5.0 by High quality product. Ordered online and received delivery in about one week. Solar panels came all the way from Oregon with no shipping charge. Panels are high quality. I use them to charge a battery bank of four 6 volt golf cart batteries used for emergency power. These panels supply more than enough power for my needs. I would not hesitate to purchase more.

Rated 5.0 out of 5.0 by Good price for Solar Purchased 8 panels to add to my off grid system. Installed on old twin angle iron bed frames (2 panels per bed frame) that give the needed support and the required 4 inch back spacing for cooling. Connectors, on the panel wireing are Auromotive type adapatable so do not cut off and void warenty, but, adapt them to any other style of spicing with the automotive push ons and connect with #12 THHN stranded wire to your charge controler if using conduit or use UV resistant 12/2 landscape lighting wire and red phase tape to identify the positive lead. Don;t forget to use the 0% financing available. You will need 2 amp hours of 12 volt deep cycle battery for every watt of solar so each panel will require 2 DS24 100 amp hour batteries or equivilant if you wish to run power throughout the night. My current system of 2800 watts has 5500 amp hours of batteries. You will also need inverters. I use 3- 2000 watt inverters and can run a 10,000 btu air conditioner and every light, computer and chargable device with all 110 volt and 12 volt needs. Panels can be wired later with micro inverters to go ON GRID so their 25 year power guarentee will let you use them for well into the future. I still run 220 volt appliances off the GRID but my Grid usage has been cut by more than half. Don't forget LED Lighting will make the panel's power go further. June 27, 2014
Rated 5.0 out of 5.0 by GOOD PRODUCT FOR THE PRICE I purchased this panel about 2 months ago, to power a small water pump to fill a stock tank. I connected it to a pump via a battery, DC timer and a charge controller. Leaned it up against a barb wire fence, and forgot about it, for a month or so. About two weeks ago we had a bad storm with high winds and a lot of rain. I found the panel the next morning laying face down in the mud about 100 feet from the stock tank. I cleaned it off by submerging it in the stock tank. Then checked it with a volt meter, it was putting out over 20 volts (unloaded). This time I secured it to a fence post and it has been working fine for the last two weeks. September 2, 2013
