Without the California Solar & Storage Association’s efforts to push each day for the rights of solar contractors at the state, county, and local levels, contractors like Renova Energy wouldn’t enjoy the success they do.”
— Patrick Sheehan, VP of Energy Storage, Renova Energy
After getting an incorrectly inflated bill for a solar permit, we worked with the experts at the California Solar & Storage Association to understand our rights. With CALSSA’s help we were able to work with the AHJ and save over $16,000 on permit fees.
