Solar Water Heating Basics

A solar water heating (solar thermal) system does not replace your existing water heater. It augments it by preheating the water with the warmth of the sun to help your hot water system use less energy. This way you always have hot water, day or night, rain or shine.

The Right System

Choosing the right solar water heating system not only maximizes the energy you save every month but also determines your rebate from the California Solar Initiative.*§ The California Solar Initiative (CSI) Thermal Program offers cash rebates to homeowners, landlords and business owners who install new solar water heating systems that meet certain eligibility requirements. For more information, visit gosolarcalifornia.ca.gov. The amount of your rebate is based on how much energy the solar water heating system is expected to displace annually, so it's important to find the right one for your home.

Savings and Rebates
