Rated 4.7 out of 5 by 42 reviewers.
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 Good Panel, but not reliable inventory The Grape panels are very good and I have bought 10 of various wattage, but my gripe with Grape is that they are constantly discontinuing product lines which makes it impossible to buy identical panels a year or so later to expand strings for optimum output with MPPT controllers. For a present example, this panel is now out of stock and so I have to look around for something with a close Vmpp to keep the panels in the strings within 5 percent. Grape has dropped various very good panels in the past, examples 235 watt poly, 250 watt mono, 100 watt mono, 150 watt mono. So if you have plans to expand your system in the future then you may consider a name other than Grape that continues their panel products well into the future, or you will find yourself with an alphabet soup collection of panels on your strings.

Rated 5.0 out of 5.0 by Excellent Solar Panels I just love the 100W Grape solar panels and they exceed my expectations, three more I will definitely order before Fall! The shipping was great, well packed with no issues and a handy email tracking link was nice. They were real easy to install and are strongly built, I know they'll last me decades and already they are saving me $40.00/month. August 5, 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 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 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 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
