My solar panels were installed in October and my bills have gone down more than expected. This is the 3rd month in a row where my NV Energy bill was in the negative and my Solar City bill is less than what I used to pay (and much better for the environment!) The original crew that installed my panels were upbeat, professional and did a great job! I had to call the company because the panels started to attract pigeons. Within two weeks, they sent someone out to clean up the roof and place netting around the panels so new nesters don't take over. Overall, I've had an excellent experience with Solar City!
