Solar Panels in San Antonio, TX

San Antonio, Texas residents are served by CPS Energy, which charges $0.12 per kWh for residential electricity. This is 29% below the national average of $0.168/kWh. At this rate, a typical household using 900 kWh per month spends approximately $1,296 per year on electricity—money that could be going toward building equity in a solar system instead.

An 8 kW solar system in San Antonio can offset most or all of a typical home’s electricity usage, saving approximately $1,152 per year. Over the 25-year lifespan of the system, that adds up to $42,001 in total savings. The estimated payback period is 19.3 years.

As a municipal utility, CPS Energy sets its own rates and rebate programs independently. Net metering is available, meaning excess solar energy you produce earns bill credits from CPS Energy. Heat pump rebates of up to $850 are also available for San Antonio homeowners.

The federal residential solar tax credit (Section 25D) expired at the end of 2025, making state and utility incentives more important than ever.
