I love to see contractors take pride in their installs which looked like a work of art. I would buy a home just to have them do the solar install. A +  ,Rating and I don't  give out compliments so easy. Thank you

 Trustindex verifies that the original source of the review is Google. I have to say this company has turned around for me.  They came out here today.Took care of everything. I'm just waiting for a day for the fire.Inspectors to take care of the solar. The pallet has been gone.Cause the guy picked it up. So I decided to give it 5 stars, because they have redeemed themselves.

 Trustindex verifies that the original source of the review is Google. Matt C. Was great. Made sure I fully understood the options I had as well as was there during installation to make sure everything went smoothly. He always answered when I had a question. If you’re planning on going Solar (you should) this is your guy.

I am very happy with result. Gensun Solar will be my choice for all future home improvement projects.
