Registration is open for Solar, Storage, and Smart Energy Expo - Southern California!


The 2019 California Solar Power Expo brought together over 1,300 attendees and 60 exhibitors from throughout the state of California and around the world. Next year, the event will be returning to San Diego as Solar, Storage, and Smart Energy Expo – Southern California.

California's aggressive renewable goals and latest policies give the Golden State even more opportunities to grow. California has set a goal of having 100% of energy come from renewable sources by 2045. In addition to this ambitious goal, California also passed a law stating that all new homes are required to install solar.

Hear from utility, private sector, and non-profit leaders from throughout the region, alongside multiple networking opportunities designed to connect you with other solar & storage professionals in the Southern California market.
