Solar water heating rebate amounts for commercial properties

Rebate amounts for solar water heating systems are based on how much energy your system is expected to displace over the course of one year. If you install a solar thermal system for process heat, cooling, space heating or a combination, your rebate will be a performance-based incentive (PBI) based on the actual metered performance of the system and will be paid quarterly over two years. CSE administers the CSI-Thermal rebate program in the San Diego Gas & Electric service territory.
