Summerlin Energy had good a salesman, but that's it. Sol-Up USA took over the work that Summerlin Energy could not complete, and did an EXCEPTIONAL job! I would start with the best (Sol-Up USA). It makes it easier, and their prices are competitive. Also, it's not just about the up front cost, its a long term investment, and Sol-Up USA does quality work and a competitive price and thats who I would recommend. Thanks to Sol-Up, I have a $0 bill from Nevada Energy and peace of mind.
