Vivint Solar

Founded in 2011, Vivint is a large solar leasing and PPA company that now operates in 14 states.

They are similar to SolarCity in that they mainly do third party owned lease and PPA agreements rather than sell solar panels outright to their clients. In comparison to SolarCity they are usually 1-2 cents per kWh cheaper than SolarCity but have had a large amount of logistics and customer service problems over the last few years meaning they have a relatively poor reputation for customer service. They seem to be working on this and their more recent reviews seem to be better but I think that consumers should beware that when dealing with any of these mega-solar companies they are really just large sales machines and there is a high likelihood you will be treated like a number from the day after your sign the contract.

Having said this you are making no investment, their contract probably will save you some money (even if this amount is much less than it would be if you bought your panels outright yourself) and so maybe it is unrealistic to expect highly personalized service. They will most likely be amongst the cheapest PPA offering in your city but they may have a higher annual escalation rate than other PPA contracts.
