About Diablo Solar & Electrical Services, Inc.
Diablo Solar & Electrical Services, Inc. is the East Bay's oldest and most experienced solar company, locally owned and operated in Concord, California since 1984. With over 42 years in business and more than 25,000 solar and battery systems installed, the company serves residential and commercial customers across Contra Costa, Napa, Marin, Sonoma, Alameda, and Solano Counties from offices in Concord and Santa Rosa. Diablo Solar offers photovoltaic solar-electric systems, swimming pool solar heating, battery backup energy storage, general electrical services, and ongoing system service and repair. All installations are performed exclusively by the company's own highly trained, certified employees — no subcontractors or day laborers — under a $2,000,000 liability insurance policy. The company manages every step of the process, including system design, permits, HOA approvals, and PG&E interconnection applications, with most new systems operational within weeks of customer approval. Customers receive free, no-obligation in-home consultations with Solar System Designers, and the team brings over 250 years of combined direct solar experience. American-made equipment options are available.
