Solar Electrical Systems (SES) is a licensed, bonded and insured General & Electrical Contractor (B1, C10, License Number 575211). SES has designed and installed residential, commercial PV systems in the Los Angeles area since 1982. In commercial solar power, SES has earned the highest customer and industry recognition by providing accurate system performance information and by being reliable, responsive and trustworthy. In residential and commercial solar power, SES is a pioneer in the field of photovoltaics (PV), building systems that produce cost-effective electrical power from solar energy.
SES founder, Greg Johanson, designed and installed off-grid PV systems in the U.S. and Mexico in the early 1980s. In 1984, Greg designed and built the world's first solar vehicle to establish the Guinness World Record category for solar vehicles. His interest in PV and vehicles inspired him to design and build the first solar powered Prius, two years before Toyota and other hybrid car manufacturers.
In the early 1990s, Greg participated in the development the California net metering law and first solar rebate program for grid-connected PV systems in the United States. Also in the 1990s, SES designed and installed PV systems for utility companies like the Sacramento Municipal Utility District (SMUD), Southern California Edison (SCE), Los Angeles Department of Water & Power (LADWP), Burbank Water & Power and other electric utilities.
By the time PV began to really become popular, SES was already rated by the California Energy Commission as the “2001 Best Photovoltaic Installer” and the “Highest percentage performance of installed systems in Southern California.”
With 30 years of experience, 5-times more than any competitor in the California solar power industry, SES is the oldest licensed California solar power firm. Solar Electrical Systems is focused 100% on PV contracting with over 1000 residential solar power systems and 250 commercial photovoltaic solar power systems installations in and around Southern California. We design and install off-grid commercial photovoltaic solar power systems for critical telecommunications links in the remote mountains and deserts of the western United States. We specialize in cost-effective distributed generation for commercial solar power buildings in Los Angeles and across California. We are the leader in residential solar power systems including Photovoltaic Net Metering solar power systems with and without batteries.
