They have earned our confidence... With other solar companies, our projects have suffered dramatically; systems need to be carefully planned, coordinated, and permitted. With the wrong contractor, coordination and approvals can fall apart, delay provision of permanent power, and ultimately delay occupancy. We have now landed on Cal Solar Inc as our go-to contractor, their team of experts and installation professionals are exceptional.
We have chosen Cal Solar over the competition for both existing buildings and new construction because of their self-perform capabilities. They have not only validated our decision with their performance but their savings analysis has delivered as expected.
