"I got multi quotes before I decided on a Solar company I was really worried about putting it on my roof And wanted to make sure I wouldn’t have one of those large bills at the end of the year. I’ve heard the horror stories! Tyler and Mr.Sunshine Soler answered all my questions. And always made themselves available. I would definitely recommend working with them. Their customer service is top notch and they stay apprised emerging solar technology. Their bid was considerably lower than the others and they were able to give me 100% coverage."
