CPS Energy - Solar PV Rebate Program

March 24, 2023


NOTE: Tranches 1 and 2 have exhausted their funding. Only Tranche 3, exclusive to commercial customers, is available as of March 2023.

CPS Energy, San Antonio's municipal utility, offers rebates to customers who install solar photovoltaic (PV) systems on their homes, schools, or businesses. Third-party owned systems (e.g., leased PV systems) are not eligible for rebates (a customer must make the upfront financial investment). The rebate is available to all CPS Energy customers for systems of at least 1 kilowatt (kW)-AC.

Current funding will be allocated through three tranches. Each tranche will have a different rebate amount:

  • Tranche 1: $2,500/project, plus $500 for locally-produced panels
  • Tranche 2: $1,200/project, plus $500 for locally-produced panels
  • Tranche 3 (commercial only): $0.60/watt, plus $0.10/watt for locally-produced panels

To be eligible for the rebate, solar projects must be priced at $4.00 per watt or less.

Rebates have a maximum of $25,000 per residential account per year and $80,000 per commercial account per year. Residential buildings applying for the commercial incentive must be established for at least one year.

System owners are responsible for obtaining all applicable permits and permissions required to install and operate the system and all work must be performed in accordance with all applicable federal, state, local, and manufacturer codes and standards. CPS publishes interconnection guidelines for systems smaller than 25 kW. Rules for larger systems will be determined on a case-by-case basis. Rebate recipients will be required to sign an agreement granting all of the renewable energy credits (RECs) produced by the system to CPS Energy.
