Net metering in San Antonio

CPS Energy Monthly Net Metering at avoided-cost rate: June through September approximately 2.0 cents/kWh; October through May approximately 1.65 cents/kWh. CPS Energy is a municipally owned utility - San Antonio is not in the ERCOT deregulated market, so residents cannot switch to a solar buyback REP. CPS Energy is the only electric provider. Export credits are far below retail (retail rate is approximately 12.4 to 12.9 cents/kWh). Important consumer alert: CPS Energy terminated its residential solar rebate program in December 2022 (portal closed December 16, 2022). Some installers have continued to market a $2,500 residential rebate that no longer exists. No active residential rebate is available from CPS Energy.

Why San Antonio homeowners are moving now

After the January 2025 wildfires, battery storage became a priority

CPS Energy's extremely low export rate (1.65 to 2.0 cents per kWh) fundamentally changes the San Antonio solar pitch compared to Dallas or Austin. With retail power costing 12.4 to 12.9 cents per kWh, every kilowatt-hour you self-consume is worth nearly eight times more than every kilowatt-hour you export. This makes San Antonio a self-consumption-first and battery-storage-first market. Joint Base San Antonio (Lackland, Randolph, Fort Sam Houston) employs tens of thousands; military homeowners, veterans, and families with USAA financing represent a significant buyer segment. The northwest side growth areas of Stone Oak, Helotes, and Alamo Ranch have large newer homes with strong roof orientations and high AC loads during San Antonio's long, hot summers.

Illustrative example

What does a typical San Antonio solar system actually cost and save?

Zero federal residential credit applied (Section 25D expired December 31, 2025). Figures are estimates based on market data as of 2026-06-29. Your numbers depend on your roof, your utility, and your bill.

System inputs

System size: 9 kW
Gross cost ($2.7/W): $24,300
Federal residential credit: $0 (expired Dec 31, 2025)
TX property tax exemption (100% of added value, Form 50-123): Applied
TX sales tax exemption on equipment (~8.25%): Applied
Estimated net cost: $24,300

Estimated outcomes

Annual savings range: $1,200 to $1,900
Estimated payback: 13 years

A 9 kW system in San Antonio costs approximately $22,500 to $26,100 gross. Zero federal residential credit applies - Section 25D expired December 31, 2025. CPS Energy's residential solar rebate program closed in December 2022 and is not available. At 5.35 peak sun hours and a retail rate of approximately 12.7 cents per kWh, a 9 kW system produces roughly 13,000 to 14,500 kWh per year. Savings depend heavily on how much you self-consume; exported kWh earn only 1.65 to 2.0 cents each. Size the system to meet daytime consumption - not to maximize production. Adding battery storage to capture midday excess for evening use significantly improves returns but adds $10,000 to $15,000 to gross cost.

Permitting and interconnection

How solar permitting works in San Antonio

Authority Having Jurisdiction (AHJ)

Permit office: City of San Antonio Development Services Department (DSD)
SolarAPP+ status: SolarAPP+: Not adopted by this AHJ
Permit fee: $275 to $525 combined (building permit plus electrical permit). Apply online at the City of San Antonio Development Services portal or in person at 1901 South Alamo Street.
Typical contract-to-energization: 4 to 14 weeks (DSD permit approximately 2 weeks; CPS Energy interconnection 2 to 12 weeks - highly variable)

We handle the permit and interconnection filings

LADBS permit application and plan set preparation
SolarAPP+ submission for qualifying systems
LADWP or SCE interconnection application
Inspection coordination and utility sign-off
Certificate of Completion delivery to homeowner

San Antonio Development Services Department does not use SolarAPP+ as of 2026. DSD review timeline is approximately 2 weeks. CPS Energy interconnection after installation is complete is highly variable: 2 to 12 weeks depending on CPS interconnection queue. This variability makes San Antonio permitting timelines less predictable than other Texas metros.

For business owners and property managers

Commercial Solar in San Antonio

CPS Energy's commercial solar rebate ($0.60 per AC watt for first 25 kW) is still active for businesses and nonprofits. Joint Base San Antonio campuses, university facilities, and the city's growing industrial corridors offer strong commercial solar potential. Businesses and nonprofits can still capture the 30% Section 48E investment tax credit if construction starts before July 4, 2026. Commercial PACE financing is also available through the City of San Antonio Economic Development Department.

See commercial solar options

Commercial solar projects must begin construction by July 4, 2026 to qualify for the 30 percent Section 48E federal tax credit. After that date, the system must be placed in service by December 31, 2027.

San Antonio solar questions

What San Antonio homeowners ask

City-specific answers. Every number references your utility and your permit office.

Is solar worth it in San Antonio with CPS Energy's low export rate?

Solar can still make sense in San Antonio, but the approach is different from Dallas or Austin. CPS Energy credits exported solar at only 1.65 to 2.0 cents per kilowatt-hour - far below the retail rate of approximately 12.7 cents. The strategy is to size your system to your daytime electricity consumption, not to maximize production. Every kilowatt-hour you use directly from your panels avoids paying retail; every kilowatt-hour you export earns very little. Battery storage helps capture midday excess for evening use.

Is there still a CPS Energy residential solar rebate?

No. CPS Energy's residential solar rebate program closed on December 16, 2022. The application portal stopped accepting residential applications on that date. Some installers continue to reference this rebate, but it is no longer available. If a solar contractor mentions a CPS Energy residential rebate, ask them to provide the current program documentation before signing anything.

How does net metering work with CPS Energy?

CPS Energy operates its own net metering under an avoided-cost structure. Export credits are: approximately 2.0 cents per kWh in summer (June through September) and approximately 1.65 cents per kWh in winter (October through May). These credits apply to the portion of your solar production that exceeds your consumption at any given moment. Credits carry forward monthly. San Antonio is not in the ERCOT deregulated market, so you cannot switch to a higher-paying solar buyback REP.

Is there a federal solar tax credit in 2026?

No. The Section 25D residential federal tax credit expired December 31, 2025. Texas has no state income tax. For San Antonio homeowners, the main financial incentives are the Texas 100% property tax exemption (file Form 50-123 with Bexar County Appraisal District) and the Texas sales tax exemption on solar equipment.

How long does CPS Energy interconnection take in San Antonio?

CPS Energy interconnection timelines are highly variable - 2 to 12 weeks after installation is complete, depending on CPS queue. The San Antonio Development Services Department permit takes approximately 2 weeks. Total contract-to-energization can range from 4 to 14 weeks. The CPS interconnection queue is the biggest variable; ask your installer about recent CPS wait times before committing to a project timeline.
