Q3 & Q4:

"I think it's a much better system than the rest that are being offered. I liked the type of inverters that they have. They're micro-inverters, so the solar cell box is not on the side of the house, and there's always a fan running. "

Sharon B. Verified High Definition Solar Customer Name
Q1:10 out of 10
Q2:Yes
Q3 & Q4:

"I've told friends about them already. They're a top notch organization. I liked the way they took care of me, because there wasn't any pressure. I spoke to a lot of other companies and wanted to purchase, not to lease or rent, the panels, and they were the ones who provided the answers."

"I liked the fact that I could attach more panels if I needed them. I wanted to try it for one year and see how much power I was making with the panels they came up with to see if I needed more, because then I could've attached them without having a different system put in. That was really good. For example, if I might make a mistake prior, and then when the time came down the road, I wouldn't be able to change it with other companies, but with this company I could."
