So it has been about 4 months with Solar City. I did see a savings of around 20% over all from last summer, but I also had my house allot cooler this year as well. last year I kept my thermostat around 79, this year it's at 76. Cooler home and about $150.00 savings on my power bill. Keep in mind that you will get 2 bills, one from Solar City for daytime use and one from Nevada Energy for night time. last summer my bill was around $400+ a month, this year was around $250.00.
No cost to install and only pay for the power you use. It's a deal. Very happy!
