These panels were of higher capacity than some of the other panels at the same price range. They look good on the roof, and seem to be working well.
Thank you for a great customer service. I did not feel rushed or pushed to buy anything when I asked for advice. I got the information I needed, all my questions were answered and I, ultimately, ended up buying these panels based on the recommendations that I have received. So far, I am very happy with my choice.
I am very satisfied with the panels as they look great, work efficiently, and were very cost effective.
These are American made panels that are very efficient and look great. Happy with the purchase and proud to support an american manufacturer.
Very efficient panels with an excellent power output. I was able to get fewer panels and still generate an adequate energy to provide my household with enough electricity.
