In response to an online qotation sevice I was contacted by several solar installation companies qouting foir outer suburban, 4.5Kw, string, 2-story system. I took the time to review all quotes and discuss these quotations with the nominated representative. I felt more assured with Odessa from United solar than the other competing solar company reps.
United also offered a good panel and a 260W panel was of interest. The instalation went smoothly and was completed as agreed, depite poor weather- no surprises! The two installers were pleasant and hrad at the job. Two great workers.
While United were not the cheapest, rather more toward the higher I did feel confident with them. The package offerred with SUMO is also worth consideration.
No horror stories with this instalation.

Approximate cost: $6300
