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.
