From people we built for

“SunHomes out-bid the competition plus their price included the back-up batteries. I'm making all my own electricity. My neighbors have had a few power outages this summer. Not me.”Joe C.
“Given the challenges presented by COVID the entire team did an outstanding job sizing, prepping and installing the system. Since installation the system has worked flawlessly.”thunderaz121
“Sun Homes was professional, organized and timely in helping with our project. I would highly recommend them as a company.”stvsanders
