At one point I was a big fan of Solar City, and a client for almost 9 years, however their reliability and service is awful. I have had 4 inverters fail since installation and 3 over the past 2.5 years. Their Solar Guard system monitors the health and power production and both recent failures went unnoticed until months later. My system has been down for almost 10 weeks, and only producing 10% of its capacity.
Solar City monitors this systems and 10 weeks later we are still waiting for the inverter to be replaced. In both instances, I have paid SC roughly $300 in fees during the most recent outage, not to mention the extra APS payments. SC will not credit me back for lost production, or credit my account for their defective equipment. Shame on them. Heck even Cox Cable is better.
I can not longer recommend them. Go seek other companies before you consider hiring them.
