Solar Water Heater Rebates

Save with a solar water heater

Your water heater is one of the biggest energy users in your home.

Switch to a solar water heater, with your gas or electric heater as a backup, and you can reduce costs up to 50 percent, according to ENERGY STAR®. Plus, by taking advantage of a CPS Energy rebate and federal tax credits, you can significantly cut the initial cost of the investment. All while making a positive impact on the environment.

Available to any CPS Energy residential or commercial customer, our solar water heater rebates are:

  • Based on SRCC’s calculated annual kWh Energy Savings performance table for San Antonio.
  • Calculated by multiplying the listed calculated savings for the system by a rate of $0.60.

The details and guidelines:

  • The maximum allowable rebate amount is $2,000.
  • The solar water heater equipment must be new.
  • The heater must be OG-300 certified by the Solar Rating Certification Corporation (SRCC).
  • Only systems currently served by an electric hot water heater are eligible.
  • Applications must be completed and approved prior to installation.
  • Permits and inspections by local authorizes are required, when necessary.
  • Post-inspections are required prior to issuance of the rebate.
