Avoid Capstone Solar

Dont use Capstone for your installations. Their support is non existent, and they turn their backs on customers. I have been trying to get in touch with them for over a month due to issues with my system that is still under warranty. SolarEdge has confirmed the issues, yet Capstone will not respond to me after multiple emails and voice mails left for them. Every issue I have had, even after SolarEdge confirms there is a problem, I have had to fight to get them to come out to repair the issue. Every time I have had to threaten legal action before anything would be done, and they still drag their feet. I think its time for a class action lawsuit
