Founded in 2000, California Solar Electric Cooperative (Cal-Solar) has been at the forefront of solar technology, designing and installing pioneering grid-tied and unique off-grid commercial solar systems nationwide. Transitioning to a worker cooperative in 2019, we’ve cemented our reputation as a leader in environmental sustainability and are committed to fostering competitive, rewarding, and meaningful employment for our worker-owners and employees. Our mission centers around enhancing the quality of life for our clients, employees, and the broader community, measuring our success by the positive impacts we create.

We service Northern California – primarily the counties of Nevada Co, Placer, El dorado, Sierra, Sutter, and Yuba.
