Solar installation in San Antonio.
ETW Energy installs solar and battery storage for homes throughout San Antonio. The city is served by CPS Energy, the largest municipally owned utility in the country, which runs its own solar program separate from Texas’s deregulated market. We design to those local rules.
Intense South Texas sun and heavy summer cooling demand make San Antonio a strong solar market, and grid resilience is a growing reason homeowners add storage.
Built for South Texas summers
San Antonio’s cooling season is long and hot, with peak demand landing right when solar produces most. We size systems to carry that load and pair them with storage when resilience or self-consumption is the goal.
One accountable team
We design, permit, and install with our own crews and handle CPS Energy interconnection — one team accountable from quote to activation.
Solar in San Antonio — common questions
Who handles solar buyback in San Antonio?
CPS Energy, the city’s municipal utility, sets the solar program in San Antonio rather than a competitive retail provider. We design your system around its current terms.
Is San Antonio good for solar?
Yes — strong sun and a long, hot cooling season that aligns with peak solar production make it a strong market, and many homes add storage for resilience.
