This is an update review. I have had solar panels from Solar City since 2011.
On August 8, 2013 I noticed that my SolarGuard was going down and not reporting electricity being generated mid-day many times a week. The sun was shining, no clouds were overhead. Also, my graph started to look really odd, so odd that I thought they had changed the software. -Basically, all of my bars were all the same height, and low. I no longer saw a bell curve as the daily report of my output. And, my reported output was lower than usual, about 10kWh less a day.
I sent an email in to customer service and got a canned reply that the reporting wasn't always accurate due to software glitches and data transmission issues. But, they assured me that my output was going to the power company just fine and the graph was in error. They also offered to help me read and understand the graph, as if I were a child.
I sent several more emails regarding the mid-day gaps in output as they were still happening (3-4 times a week) months later. I was also wondering why my output total in December, when APS does an annual bill that clears banked hours, was so much less than the prior year. -Going in to August I had banked more hours than the year before.
Finally, on March 12, 2014 (seven months later) a technician called me and had me read the inverter, reboot the inverter several times and check a few other things. He made an appointment for a visit on the 14th, where it was discovered that my inverter was faulty. It was shutting down and/or rebooting once energy input to it hit certain numbers. This was why there was no production at mid-day, the inverter was turning itself off. This was also why my online chart was so flat, when the input hit a lower than mid-day number it would re-boot itself.
So, it was very clear that I had lost a lot of output over a seven month period. And, while I had notified SC about the problem on several occasions, customer service did not pass my reports on to tech support; they chose to treat me like a child who wasn't understanding that there could be glitches in internet reporting of data.
I emailed support to complain about the way I was treated, and about the loss of over 200kWh a month for seven months. Here is the entire email reply:
"Dear Bob,
Thank you for your email. This is Terri, with SolarCity Customer Account Management. I hope that you are having a wonderful day.
I'm happy to hear that we were able to get this resolved for you. If there's anything else we can assist you with, please don't hesitate to reply to this email for further assistance. Thank you and have a good day!"
No apology, no admission of anything wrong on their end, and no addressing the issue of my lost kWh = dollars.
I sent another email pointing out that there is clearly a serious problem with how customer service people handle tech support issues and how I had been repeatedly ignored when I had a real and serious problem with my system. And that problem had continued for seven months. I also pointed out that it was fairly annoying for them to tell me how happy they were about it all.
Here is the final response:
"Hi Bob, this is Terri again. Thank you for your patience and replying back.
First off, let me apologize for not immediately addressing the inverter issue that had just recently been resolved. I definitely should have, as I can only imagine that it was a very frustrating situation. More than anything, I was genuinely happy that the problem had been resolved for you.
In regards to the lost production during the time your inverter was not producing, that would be covered by our performance guarantee. We guarantee that your system will produce a certain amount annually, and if it falls short, we will compensate you for that. So, if your inverter not producing for that time period causes your system to not produce what we guaranteed, we will send you a refund check for the difference.
If there's anything else we can assist with, please don't hesitate to reply to this email."
So, in the end, I lost a chunk of cash. I got treated like a child for seven months for reporting a real and serious problem. Their customer service won't be trained to respond appropriately (by calling a service tech) to this issue in the future. They won't admit that there is a HUGE gap in communication between customer service and the technicians who work on the equipment. They also won't admit that seven months is a ridiculously long time to wait for a service call to get looked at then fixed.
I was unhappy for seven months while my equipment was faulty and underperforming by 30%. It was nice to have it finally fixed, but, nobody bothered to apologize until after my second complaint, and it's not a very good apology. The company shows no understanding of what went wrong, and has made no effort to fix the system that led to me being brushed off for seven months.
BEWARE: Tech support may take seven months to respond to tickets!
