Remarkably Excellent Experience and Quality
Overall, I would buy this brand 100 more times. The construction of the panel is the highest level. I get the desired amount of amps and volts as I predicted and expected during full sun, and reasonable during shade. The cables are substantial, I do not know if they are copper or alum. but they are thick and long enough. The tech support answered their phones and knew what they were talking about. Remember, you are talking to Oregonians, they are sincere and respected, please be the same with them. (I had a general question about MPPT and PWM with the Poly panel kits.)
Two things I would like. Cables on the panels in red and black, instead of all black. But for those who have not bought, the kits will not allow you to make a polarity mistake with the pre-made connections, just always always always verify with one you are putting into the controller, every time. Second, I have had to disconnect the remade connections several times, for upgrades, and the connectors are not friendly to old man arthritis fingers, just wishing it was a bit easier, as I can not pinch anything.
That is it, these are awesome in my testing. Ordering a 3 panel kit today.

Came as ordered and was an easy install for a guy that had never done one.
Seems to be working great no more dead batteries any longer or lack of evening power. Fridge runs all night with no issues.
Installed the system on my RV.

An excellent product with decent paperwork for the install. Works like a charm and the controller is well over rated so that I can expand my system threefold. The paperwork for the controller is minimal but Grape Solar has phone numbers available to contact them which I have yet to do. It was a great investment and I plan to expand in the very near future!

We are very happy with our Grape Solar purchase. Very easy to set questionup and very affordable. We might need to add more wattage in the future. If we do, we will purchase Grape Solar again.

This is a great starter system. Easy to install good instructions. I will be buying a few more of these (panels only) to augment my home power needs, so the instructions on how to expand were very helpful.
