About Cobalt Power Systems Inc. in the San Francisco Bay Area

Comprehensive Services from Our Bay Area Solar Company

Cobalt Power Systems, Inc. has been installing complete residential and commercial photovoltaic (PV) and energy storage systems since 2003 and has grown organically over 20 years of operation. The company was founded by Mark Byington in the garage of his Los Altos home.

We initially focused on residential solar but expanded into the commercial solar market successfully several years ago. We’re proud to offer Maxeon solar panels with a 40-year warranty - only available through a Maxeon Partner! Cobalt was the first SunPower Elite Dealer™ in the nation and was named SunPower Dealer of the Year. Cobalt is also a Tesla Premier Certified Installer. We see the integration of energy storage as the next component of the company’s growth.
