City of San Marcos - Distributed Generation Rebate Program

The City of San Marcos offers a rebate to help offset the cost of installing a grid-tied solar photovoltaic system on your property. You must be an existing SMTX Utility customer with an account in good standing and obtain pre-approval from the utility before installation; single-family homes must also meet specific energy efficiency criteria set by the utility. Your solar system must be professionally designed and installed to qualify for the rebate, and any excess power you generate can be sold back to the grid.

This program creates customer demand for grid-tied solar installations in the residential, commercial, agricultural, industrial, nonprofit, school, and institutional sectors across San Marcos. All systems you design and install must be professionally executed and meet utility pre-approval requirements; residential customers must satisfy the utility's energy efficiency standards before moving forward. The rebate structure helps make solar more affordable for your customers, supporting market growth in the area.

The Distributed Generation Rebate Program provides rebates to incentivize grid-tied renewable energy systems (solar PV and wind) across six sectors—residential, commercial, industrial, local government, nonprofit, schools, agricultural, and institutional. Customers must be pre-approved by the utility, and single-family residential applicants must demonstrate compliance with utility-determined energy efficiency criteria; all systems require professional design and installation. The program is administered by the City of San Marcos Electric Utility and directed to existing utility customers with accounts in good standing, supporting distributed generation adoption while managing grid integration.
