How We Evaluate San Antonio Solar Companies
We evaluate San Antonio solar installers based on NABCEP certification, Texas TDLR electrical contractor licensing, CPS Energy interconnection experience, and verified customer reviews.
CPS Energy (City Public Service) is San Antonio's municipal utility and operates a standard net metering program for residential solar customers. CPS Energy also offers a solar rebate of up to $1,000 for qualifying residential installations — your installer must be a CPS Energy approved contractor to access this rebate.
San Antonio's high solar irradiance, hot summers (which drive strong AC loads offset by solar), and CPS Energy's rising rates have made solar increasingly attractive for Bexar County homeowners.

Frequently Asked Questions About Solar in San Antonio TX
Does CPS Energy offer net metering?
Yes. CPS Energy offers net metering for residential solar customers. Solar energy exported to the CPS grid earns a credit at CPS Energy's retail avoided-cost rate. Credits apply to your monthly bill. CPS Energy also offers a residential solar rebate of up to $1,000 for systems installed by CPS Energy approved contractors. Your installer must be a CPS Energy approved Solar PV contractor to access the rebate.
What is the average cost of solar panels in San Antonio TX?
A typical 7–9 kW residential solar system in San Antonio costs between $17,000 and $26,000 before incentives. After the 30% federal ITC and CPS Energy's $1,000 rebate, the net cost drops to approximately $10,900 to $17,200. San Antonio homeowners see payback periods of 7 to 10 years due to the high irradiance and strong AC loads that solar offsets during peak summer hours.
Is San Antonio outside the ERCOT deregulated electricity market?
Yes. San Antonio is served exclusively by CPS Energy, a municipal utility that is not part of the ERCOT deregulated market. Unlike Houston or Dallas customers, San Antonio homeowners cannot choose their retail electricity provider — CPS Energy is your only option. This simplifies solar interconnection (one utility, straightforward net metering program) and makes CPS Energy rebate eligibility straightforward to verify.
How does battery storage work with CPS Energy solar?
Battery storage can be added to any CPS Energy solar installation. CPS Energy's net metering program credits exported solar at a lower rate than retail — battery storage allows you to store solar energy for evening use at the full retail rate rather than exporting at the lower avoided-cost rate, improving your economics. Battery storage also provides backup power during CPS Energy outages, which have become more valued after Texas's 2021 winter weather event.
