Notice: PG&E stopped accepting solar water heating program applications August 1, 2020. In compliance with Assembly Bill 797, Advice Letter 4090-G established July 31, 2020 as the final date to submit new applications to the program.
Reducing the amount of hot water used in your home or business can reduce the size and cost of the system that you must install. Before you install a solar water heating system, consider other energy efficient upgrades. The upgrades can include high-efficiency washers and dishwashers, and low-flow showers and toilets.
Ensure your roof is in good shape. Consider replacing your roof when you install your hot water heating system, if the roof is in poor condition. Ensure that enough roof space is exposed to the sun to accommodate your system. Establish a space near your current water heater to install the separate solar storage tank.
Solar water heating systems are designed to be reliable. A typical setup can last 20 to 25 years. In addition, the systems require very little maintenance if they are installed properly.
