I got quotes from 2 or 3 companies and still believe that Vivint Solar is likely the cheapest for KWH and likely has the lowest rate increase year over year until the 20 yr lease is up; that however, comes at a high price. I liked the sales person but several things he told me (sales promises) turned out not to be true, which carried very little weight with Vivint Customer Service. With Vivint Solar there is no give, it's all take, no consideration for what you were told. Their billing system is archaic and I will be dealing with that every month for the next 20 years. Working with Customer Service is not possible; they are rude, arrogant, and they know that they don't need to listen to you once the contract is signed, they've got you and you are no longer relevant. This company is a very large conglomerate and it shows.
