Key Takeaways
- San Antonio sunshine can support rooftop solar, but your roof, electricity use, and utility plan determine how well a system fits your home.
- A typical 8.91 kW system is estimated at $25,222, with modeled 25-year savings of about $72,799; actual results depend on your home and utility plan.
- Your utility affects solar options and bill credits: CPS Energy customers can’t lease through third-party ownership, and Texas has no single statewide export rate.
San Antonio Electricity Prices
Electricity prices matter over time—here’s what the Texas figures show for San Antonio homeowners considering solar.
The chart reports Texas electricity prices rising from 12.1¢ per kWh in 2021 to 14.9¢ in 2024, about 23%. These are statewide figures, not a San Antonio-specific rate; the national average rose from 13.7¢ to 16.5¢.
Solar panels can generate some of a home’s electricity, reducing how much power it needs to buy from the grid as rates change. Impact depends on system size, household use, and utility plan; solar doesn’t necessarily eliminate an electric bill.
Over the system’s life, producing power at home may help limit exposure to utility price changes and lower electricity costs. The value depends on installation costs, system output, and rates. See our home solar guide for basics.
Price of Energy: Texas vs National Average
San Antonio Area Utility Providers
San Antonio-area customers may get electricity from CPS Energy or PEC. The latest utility data provided is from 2023; 2024 data is not yet available. Average prices were 12.1¢ per kWh for CPS Energy and 11.7¢ for PEC.
Both providers’ 2023 prices were below the Texas average of 14.5¢ per kWh and the U.S. average of 16.0¢. These are average-price comparisons, not explanations of why provider rates differ or a prediction of any household’s bill.
Solar can supply some of a home’s electricity and may reduce how much it draws from the grid. Whether solar installation in San Antonio changes energy costs depends on factors such as household use, the roof, and the utility arrangement.

Texas Solar Incentives
San Antonio homeowners may find state and local programs that help offset solar installation costs. Review the solar incentives in Texas below.
Options may include Oncor’s project-specific incentive of up to $9,000, battery rewards from CPS Energy, TXU Energy, or Gexa, a Texas property-tax exemption, and provider-specific export compensation. Eligibility varies by utility, provider, equipment, and plan.
The federal 30% residential tax credit is unavailable for 2026, but state and local incentives remain. With LightReach leasing, Palmetto handles the commercial ITC, passing savings on through lower payments.
| Incentive | Type | Description | Source |
|---|---|---|---|
| CPS Energy My Battery Rewards | Battery Demand-Response Bill Credit | Residential CPS Energy customers may receive a $10 bill credit for each qualifying program event in which their enrolled battery provides verified demand reduction. | Learn More |
| Texas Solar Property-Tax Exemption | Property Tax Exemption | Texas Tax Code §11.27 exempts the portion of appraised value attributable to a qualifying solar energy device used primarily to produce and distribute energy for on-site use. | Learn More |
| Texas Solar Export Compensation and Net Metering Policy | Net Billing / Utility-Specific Export Compensation | Texas has no statewide net-metering mandate or uniform solar buyback rate; export compensation depends on the homeowner’s retail electricity provider and plan. | Learn More |
CPS Energy’s My Battery Rewards program provides a $10 bill credit for each qualifying event. CPS Energy may call events during periods of high demand or grid emergencies; this is an event-based payment, not an upfront rebate for buying a battery.
Participants must be residential CPS Energy customers with an active account and a customer-controlled behind-the-meter battery that has completed the required distributed-generation and interconnection process. Participation in each event is voluntary, and the credit depends on CPS Energy verifying the battery’s contribution under the program terms.
Texas Tax Code §11.27 provides a property-tax exemption for the increase in appraised value attributable to a qualifying solar energy device used primarily to produce and distribute energy for on-site use. This is not a cash rebate; it can reduce the taxable appraised value attributable to the qualifying equipment.
Homeowners generally apply through their county appraisal district using the Comptroller’s Form 50-123 and should check local filing procedures and documentation requirements. A battery’s eligibility may depend on whether it qualifies as part of a solar energy device and on the appraisal district’s application of the law, so do not assume every battery installation qualifies automatically.
Texas does not provide a statewide net-metering program or a uniform required buyback rate for residential solar exports. The financial value of electricity sent to the grid depends on the retail electricity provider and the specific plan available at the home, rather than being set by a single statewide solar credit.
Before choosing a plan, homeowners should review the written export-credit rate, how credits are calculated and carried forward, whether credits expire, and whether delivery charges or other fees apply.

How to Choose a Solar Installer in San Antonio
Verify the license
Texas does not have a separate general solar-installer license. Non-exempt electrical work must be performed through a licensed electrical contractor, and covered residential solar contracts must provide for installation by one. Ask which electrical contractor will do the work, and look up the contractor through the Texas Department of Licensing and Regulation (TDLR) license search. Since September 1, 2026, residential solar retailers and salespeople generally must also be registered with TDLR, subject to exemptions. Ask whether that requirement applies to the seller you are dealing with.
Look for certified installers
Ask who on the project holds each credential and what it covers. NABCEP certification is a credential to investigate when comparing solar professionals; check the specific certification and its current status rather than relying on a logo alone. Manufacturer certifications relate to particular equipment or brands, so ask what the installer is certified to install and whether the credential affects service or warranty handling. Treat credentials as useful comparison points, not substitutes for a clear contract and references.
Compare quotes the same way
Request written quotes with the same assumptions and compare these items side by side:
- System size in kilowatts (kW) and the price per watt.
- Panel and inverter brands and models.
- Estimated annual production in kilowatt-hours (kWh/year), plus the assumptions behind the estimate.
- Warranty terms for panel product and performance, inverter, workmanship, and roof penetrations.
- Who will obtain permits, arrange inspections, and submit the interconnection application.
- Total cost or monthly payment, and whether a payment escalator applies.
Compare what is included, excluded, and guaranteed—not just the headline price or projected savings.
Permits, interconnection and your HOA
Building and electrical permits and inspections are handled by the local authority with jurisdiction; the responsible office and requirements depend on the property location. Interconnection is handled through the electric utility serving the home. Ask the installer to name that utility and explain who submits the application and tracks approval. Homeowners may encounter names such as Reliant Energy Retail Services, TXU Energy Retail Co, LLC, City of San Antonio, or Austin Energy, but confirm which electric utility serves your address; cooperative and municipally owned utility customers may have utility-specific requirements. Texas generally bars property owners’ associations from prohibiting or restricting solar energy devices, with statutory exceptions. See Texas Property Code §202.010(b)–(d) and check how the exceptions apply to your situation.
Red flags
- Pressure to sign the same day or accept terms before you can review them.
- Unlicensed crews, or out-of-state crews that cannot clearly identify the licensed electrical contractor responsible for the work.
- Vague production estimates without a written annual kWh figure and supporting assumptions.
- A large upfront deposit without a clear written explanation of what it covers and when payments are due.
- Promises of federal tax credits for homeowner purchases made in 2026; homeowner credits ended December 31, 2025.
Palmetto is one installer you can include in your comparison, and it offers a lease option through LightReach.
Leasing Solar Panels
In San Antonio, your utility matters: CPS Energy prohibits third-party ownership (TPO), so Palmetto LightReach leases and power purchase agreements (PPAs) aren’t available to CPS Energy customers. In nearby areas served by Pedernales Electric Cooperative (PEC), a solar lease is available, subject to address and eligibility.
With a lease, you pay a set monthly amount, while the provider owns the system and handles covered maintenance. This can avoid a large upfront cash payment and the maintenance responsibilities that come with owning a system outright.
Lease terms and utility rules affect the details. Compare buying versus leasing solar, and learn about Palmetto LightReach.
Go solar without the investment
With LightReach, there are no investment costs to recoup, loan payments to manage, or maintenance needs to take on. As soon as your panels are active, your solar savings are too!

Yes. CPS Energy customers in San Antonio have monthly net metering. Excess solar credits carry forward as a dollar balance, valued at about 2¢ per kWh from June through September and 1.65¢ per kWh from October through May.
Unused credits roll over month to month but are forfeited each December without a payout. The rules may differ for nearby homes served by another utility, such as PEC.
Solar panels may increase a San Antonio home’s value when the system is owned. A Zillow study found homes with solar sold for approximately 4.1% more, though this is not a San Antonio-specific estimate or a guaranteed increase.
That finding applies to purchased or owned systems, not leased or other third-party-owned systems. A leased system may affect resale differently because the buyer may need to assume the lease agreement.
In San Antonio, an eligible homeowner may use a LightReach lease with no upfront cost and a fixed monthly payment. The calculator above estimates $82–$153 per month, or $114 for a typical medium home. Availability depends on your utility; CPS Energy customers cannot use third-party leases, while eligible PEC customers may.
A cash purchase is another option: estimates range from $18,797 to $32,851, with a typical 8.91 kW system at $25,222. The federal 30% residential solar tax credit is no longer available for cash purchases following the 2025 federal law change.
A solar lease lets a provider own and install the panels while you pay a monthly fee. Palmetto’s LightReach lease has no upfront cost; one payment covers the system, installation, monitoring, maintenance, and protection, including a 90% Production Guarantee.
For a typical 8.91 kW San Antonio-area system, the estimated lease payment is about $114 per month, based on Texas’s 1,339 kWh/kW/year production ratio and a $0.115/kWh rate. Payments are typically below current electricity bills, so savings may begin when the system is active. CPS Energy prohibits third-party-owned leases; availability depends on your utility and address.
San Antonio homeowners may find an Oncor project-specific incentive of up to $9,000, CPS Energy battery credits of $10 per qualifying event, and a Texas property-tax exemption on the added appraised value of qualifying solar equipment. Eligibility varies by program and utility.
Texas has no statewide net-metering rate; export credits depend on the retail provider and plan. The 30% federal residential credit is no longer available for cash purchases after the 2025 law change. Palmetto says LightReach leases still benefit from the commercial ITC it claims, with savings passed through in lease pricing.
Palmetto Solar is an option for San Antonio homeowners comparing solar installers. We’ve completed 8,405 installations in Texas since 2020 and work with an installation network across the state.
The best fit depends on your roof, electricity use, utility, and budget. Compare system designs, warranties, total costs, and financing terms. If you’re served by CPS Energy, note that third-party-owned solar leases and power purchase agreements aren’t available.
Solar panels are generally low maintenance. In San Antonio, check periodically for debris or visible damage, and monitor system output for changes.
With LightReach, where available, Palmetto owns the system and handles monitoring, maintenance, and repairs at no extra cost. It also includes a 90% Production Guarantee. LightReach is not available to CPS Energy customers.
