First the sales people lied about how it works and how much money I would save. They gave me a certificate to have the panels removed at their expense while I got a new roof in 5 years. Well, they filed bankruptcy and the billing company said, No. Not their problem. It seems that though it should have been grandfathered in no one seems to be responsible but me. When my roof leaked at year 1, 2 and 2.5, no one was responsible to fix it. I was told I wasn't leasing. I purchasing power from them like from Edison. They would sell off excess and sell me back the remainder at the end of the year. I would have $.00 bills based on my usage. I went from approx. $50 a month Edison bills to $145 solar bills. Lies! Lies! Lies!!!!!! Stay away from Verengo and their billing company Corinthian.
