Go Solar with San Antonio’s Local Solar Experts
The San Antonio residents benefit from a different type of solar energy market compared to that of the other big cities in Texas. CPS Energy is a publicly-owned utility company, meaning that there is not an open retail electric marketplace, nor does there exist any distinction between TDU and REP companies. The money you save using solar depends on your consumption, exports, and the efficiency of your solar system relative to CPS Energy’s billing system.
Solar SME offers custom solar installation in San Antonio, TX, with solar, battery storage, EV charging, maintenance, and other energy solutions designed around your property and energy needs.
Why Does San Antonio's Solar Math Work Differently?
CPS Energy does not provide 1:1 net metering. The excess electricity generated by solar energy is provided with an avoided cost rate. CPS Energy’s recent billing information indicates that the average cost of electricity in CPS is 13.4¢/kWh for July 2026, while its recent solar billing information indicates the excess generation credit rate as 1.65¢/kWh from October to May and 2.02¢/kWh from June to September.
This implies the significance of using the energy consumed within the premises. Solar energy used within the premises will help in reducing the cost of purchasing electricity from CPS Energy, whereas excess electricity sold back to CPS Energy will provide a low credit rate. A properly sized solar battery can store more of your daytime production for use later.
Key Reasons San Antonio Property Owners are Considering Solar
San Antonio property owners consider solar not only because of the clean-energy aspect. The unique CPS Energy billing model allows one to save money by using and producing own electricity.
Reduce Grid Electricity Use
Produce electricity on-site and use maximum solar energy during the day.
Maximize Solar Savings
CPS Energy buys any extra solar production produced at an avoided cost rate, which makes self-consumption integral part of system design.
Power During Outages
Solar + Battery Storage combination can be used as backup electricity source during blackouts for certain essential loads.
More Energy Independence
Produce more own electricity to increase independence from the grid.
Contribute to San Antonio's Clean-Energy Targets
CPS Energy keeps expanding solar and energy-storage capacities as part of long-term generation plan.
Solar + Battery Backup for San Antonio
The weather conditions in San Antonio are a mix of both heat extremes and severe storms. The solar panels produce power during the day, whereas battery storage will keep some appliances working even during the power outages. Furthermore, battery storage will help improve the cost-effectiveness of the CPS Energy solar panel system by storing surplus electricity that could otherwise be exported for the smaller avoided cost credits.
Understanding CPS Energy's Solar Rules
The rules for solar customers in San Antonio are different from those deregulated Texas energy marketplaces for homeowners . The municipal utility in San Antonio is CPS Energy, which means that there is no competitive retail electricity provider market where you can choose a buyback program separately. You will receive savings based on your electricity consumption, CPS Energy’s retail rates*, and credits from any extra solar production.
Customer Type | Current Rate Information | Solar Savings Potential |
Residential* | 13.4¢/kWh average projected electric cost for July 2026 | Solar can reduce the amount of electricity purchased from CPS Energy |
Residential** — 12-month average | 12.8¢/kWh (Aug. 2025–July 2026) | Useful benchmark when estimating annual solar savings |
Commercial*** | Rates vary by commercial rate class, usage, and demand | Solar can reduce purchased energy depending on the system and rate structure, help manage demand-related costs |
Commercial Solar Incentive | $0.60/AC watt for first 25 kW + $0.40/AC watt above 25 kW | Available to qualifying small businesses, schools, and nonprofits; commercial rebates are capped at $80,000 or 50% of invoice cost, whichever is less |
How CPS Energy Pays for Excess Solar
CPS Energy does not use traditional 1:1 net metering. Instead, excess generation is credited under its solar billing structure at an avoided-cost rate.
This makes the use of on-site solar power production in San Antonio especially attractive, as it is more cost-effective than selling the same amount of electricity to the grid in exchange for the avoided cost credit.
Solar Energy | How It Is Treated |
Solar power used immediately | Offsets electricity you would otherwise purchase from CPS Energy |
Excess solar sent to grid | Receives an avoided-cost credit rather than a 1:1 retail credit |
Solar stored in battery | Can be used later instead of exporting as much excess generation |
Solar + battery | Helps increase self-consumption and can provide backup power during outages |
Net Billing vs. Net Metering in San Antonio
CPS Energy does not offer traditional 1:1 net metering. Instead, its solar program uses net billing, where excess solar electricity exported to the grid receives an avoided-cost credit. Using solar power on-site generally provides greater value than exporting it, making proper system sizing and battery storage important considerations for San Antonio solar customers.
