Rooted in Restoration and Diagnostics
A Structural-First Approach to Solar System Services
Unlike most solar installers, Sun Diagnostics was built from a foundation of fire restoration and roofing experience dating back to 1994. This background enables us to identify and resolve root causes of leaks, production drops, and equipment failure that other firms often miss. Every service is performed by our fully trained, manufacturer-certified employees, never subcontractors. With direct owner oversight and personal warranties up to 20 years, we provide peace of mind for homeowners who demand true accountability and technical excellence.
