Customer Reviews for Grape Solar 280-Watt Polcrystalline Solar Panel-DISCONTINUED

Two of these panels are giving us as much power as our tracker array of 10 panels. Yes, the panels on the array are smaller and around 14 years old, but doubling our power with just two of these guys is a boon for us. I used to have to run the aux generator when working in my shop making Laughing Crow Flutes, but now the generator sits idle most of the time, saving us gasoline and wear and tear on "Gennie". We plan to upgrade the array on the tracker with 4 more of these panels after winter and up the wattage to three times the power we had before starting the upgrade. We live in an Earth Ship outside Taos New Mexico, so almost all our power comes from solar. We have back up generators for the dark days, but even on a cloudy day, we're getting up to a good 100 watts from the two new panels. When the skies are clear and the sun is overhead, we're cooking. The price is comparable to all the other options and the free shipping is a plus. We're very pleased with the results.

I currently have four of these, and according to current and voltage numbers generated from the charge controller I have seen up to 380 watts produced in full sun with ambient temps in the mid seventies. I will probably buy more.

Bought 2 of these for boon docking in my RV. Only complaints I have is packaging is pretty sad and it took 2 weeks to be received. Surprisingly did come without damage as the panels were only protected by a thin sheet of cardboard. HD was very helpful in tracking packages as they come factory direct through a company called estes express. These panels do weigh about 80 lbs apiece so keep that in mind when ordering.

Panel is great , I use with tie grid inverter , takes longer time to get it , but made very good .

Works as advertized.It powers my camper battery bank with power to spare.

output V. was 8V. & 1.8 A on a very,very cloudy day.The third day was very clear & bright.The PV provided 7.7 amps at 48 V.Burned out my small 12 volt battery charging controller.Unless my meter was defective, this unit was providing 369.6 watts to the controller & 6 12V batteries.I`m going to need a much larger controller.

The best thing is that Home Depot can ship these for 50 bucks. If only buying one panel many places charge 50% of cost for shipping.
