Right from my first conversation with Mark I felt confident that United Solar were a professional company. I had spoken to other companies about Solar and did not feel the product they were offering stacked up. The office staff and installers at United Solar kept us informed all the way about what was happening and when. Even though we paid a little more for our system than some others were quoting. We got what we paid for. Proper components from reputable companies. I cannot recommend United Solar highly enough. If you want an inferior product installed by lesser qualified installers by all means go with the big advertisers. But if you want the job done properly the first time use United Solar.
