Customer Reviews
Denise Luttrell
Custom Solar did my original rooftop system in 2013. It has worked without issue since then. Recently they installed a battery backup for my system, and once again I found them to be competent, courteous, and communicative. I'm very happy with their work, and highly recommend the company.
