I was very pleased when I pulled the two 100 watt grape panels out of their boxes. They were well packed, no damage at all. I hooked them up to a Victron 75/15 controller and once the sun came out from behind the clouds they were producing 210 watts of power. I made them into a portable suitcase and as they were so inexpensive thought I would need to beef up the frames. That wasn’t needed, they are well made units. Much better than I expected for $89. I have had them now for two weeks powering my RV from Bulk to Float each day.

I made 3 portable cases out of 6 grape solar 100 watt panels and hooked them up to two 40 amp pwm grape solar controllers. Then built a 6V 245 AH x2 12v in series then tied 3 in parallel totaling 735 AH 12v bank. Hooked up a 6,000 watt 12,000 watt max inverter. I put electronics in my truck tools box and hardwired a 30 amp RV RECEPTICLE BOX into inverter and mounted it to tool box and put the 6 6v batteries into an army trunk with vents custom drilled around the side top. And plugged in the panels and RV worked awesome. I will upload pictures if I can.

Great panels I have 2 100wts and now adding a separate 50wt system.for off grid.easy to connect everything together.

I mounted 4 panels, in parallel, connected to my EPEver 40 amp MPPT 4210AN controller and 2-6 volt deep cycle batteries (in series) and I’m very happy with the results. I’m planning on 2 more panels along with 2 more batteries

Now using two Grape 100-Watt panels. They started charging the battery just after sun-up. Received both panels within two or three days of placing order.

The panel was easy to set up and is working great.

Good price for 100 watt panels. Easy to install, but I wish I could have found reasonably priced mounts that would have allowed tilting. Time will tell how they hold up. So far they are working as expected.

I used two of these to replace two 60 Watt modules on my RV when I replaced the RV roof about two years ago. This is matched with a Morningstar 15 Amp PWM charge controller, two group 27 size 220 Amp-hr deep cycle batteries and a 1100 Watt sine wave inverter. The system works great.
Note that the system does not produce the rated output. That is typical of solar modules. The peak output is about 120 Watts. But it produces plenty of energy for my needs for dry camping without a generator.
I got the Z mounting brackets then decided that would not work on the RV. I needed a system that would allow me to remove the modules for maintenance.
I cut some aluminum angle and made my own Z brackets that bolt together so I could remove the modules by removing easily accessible bolts. See photos.

A bit more expensive than some of the cheaper made ones out there but this panel is a lot more durable and the customer service could not be beaten. Every question I had about the Grape Solar System starting from purchasing the 50 watt starter kit to adding on a 40 amp charge controller and two 100w panels and every step of the way Steve at customer service answered my email the day I wrote it to them.

Very satisfied with Grape Solar, both their solar panels and controllers.
They provide a great product at a fair price.
