Solar Water Heating for Your Home

Solar water heating is a cost-effective way to boost your existing water heater’s efficiency and supply, while reducing utility costs.

A New Generation of Efficiency

A solar water heating system captures the sun’s heat and works with your conventional or tankless water heater to heat your water more efficiently. Unlike solar power (photovoltaic) systems that generate electricity, solar water heating systems absorb and transfer solar heat energy, so the technology is also referred to as solar thermal.

Bright Benefits

Upgrading to solar water heating can help you:

  • Enjoy an instant and longer-lasting supply of hot water
  • Maintain hot water supply during unexpected utility disruptions
  • Lower your water heating bills
  • Receive federal, state and/or local rebates
  • Increase your home’s property value
  • Reduce your energy consumption

State Rebate

The California Solar Initiative (CSI) Thermal Program1 offers cash rebates to Southern California Gas Company customers who purchase and install qualifying solar water heating systems. Rebates are based on how much energy the solar water heating system is expected to save annually, with a rebate of up to $2,719 for residential customers.

Income-eligible residential customers who are participating in a CPUC-approved gas corporation Energy Savings Assistance Program (ESAP) or who have income-eligible renters that meet the requirements in Public Utilities Code (PUC) Section 2861(e), can receive rebates of up to $3,750.

Eligibility

To be eligible for a CSI-Thermal Program rebate, a qualifying2 system must be installed by an eligible contractor or eligible self-installer.Your contractor will complete the Energy Efficiency Survey, ensure that your system is eligible, install your system according to regulations and submit the application for you.

 

Self-Installers

If you wish to install your own solar water heating system, you must attend the no-cost self-installer workshop and you will be issued a registration key code at its conclusion. That code can be used to apply for your incentive. All rebate applications must also include a completed Home Energy Efficiency Survey.
