San Antonio Electricity Prices
Electricity costs in San Antonio have been climbing steadily — and for many homeowners, that trend is hard to ignore.
Texas electricity rates rose approximately 23% from 2021 to 2024, jumping from 12.1 cents to 14.9 cents per kWh. For San Antonio families, that increase shows up directly on monthly utility bills.
Solar energy gives San Antonio homeowners a way to generate their own power at home, reducing how much electricity they need to purchase from the grid — and softening the impact of future rate increases.
Because solar panels typically last 25 years or more, the long-term value compounds over time. The higher utility rates climb, the more meaningful the savings from a home solar system become for San Antonio residents.
Price of Energy: Texas vs National Average
San Antonio Area Utility Providers
San Antonio homeowners are served primarily by CPS Energy. According to 2023 data — the most recent available — CPS Energy’s electricity rate was 12.1¢ per kWh, giving San Antonio residents a useful benchmark for understanding their energy costs.
That 2023 rate of 12.1¢ per kWh sits below both the Texas state average of 14.50¢ and the national average of 16.0¢ per kWh — a difference driven by CPS Energy’s diverse generation mix and its status as a municipally owned utility.
Even at today’s relatively competitive rates, solar installation in San Antonio, TX can help homeowners lock in predictable energy costs long-term — reducing exposure to future rate increases that are common across Texas and the broader U.S.

Texas Solar Incentives
San Antonio homeowners have access to several solar incentives in Texas that can help offset the cost of going solar — starting with two that apply statewide.
Texas law exempts 100% of the added home value from a solar installation from property taxes. The state also protects your right to install solar panels, even if you live in an HOA community. Both apply to all San Antonio homeowners.
Some utility-based rebates in the table below apply to specific service areas outside San Antonio. Homeowners who choose solar leasing through LightReach benefit from simplified incentive management, as Palmetto handles the commercial side and passes savings through lower monthly payments.
| Incentive | Type | Description | Source |
|---|---|---|---|
| Texas Solar Property Tax Exemption | Property Tax Exemption | Texas homeowners receive a 100% property tax exemption on the added home value from a solar installation under TX Tax Code Section 11.27. | Learn More |
| Texas Solar Energy Devices Franchise Tax Exemption | Tax Credit | Texas businesses can deduct the cost of a solar energy device from their state franchise tax liability. | Learn More |
| Tesla Electric Virtual Power Plant (VPP) Program | Rebate | Powerwall owners in CenterPoint service territories can earn a $10/month electric bill credit by enrolling their battery in Tesla Electric’s Virtual Power Plant program. | |
| Texas Solar Rights Protection (HOA Solar Access Law) | Net Metering | Texas law prohibits HOAs, municipalities, and other entities from preventing homeowners from installing rooftop solar panels. | Learn More |
Under Texas Tax Code Section 11.27, the added value that a solar energy system brings to your home is 100% exempt from property tax assessments. Since solar panels can increase a home’s market value by $15,000–$25,000, this exemption can save homeowners an estimated $400–$600 per year in property taxes — potentially more than $10,000 over the lifetime of the system.
To qualify, the solar system must be owned (not leased) and primarily used to produce and distribute energy consumed on-site. Eligible systems include solar photovoltaic panels for electricity generation as well as solar thermal devices such as solar water heaters. The exemption has been available to Texas homeowners since 1978 and applies statewide.
To receive the exemption on your tax bill, residents of San Antonio must file Form 50-123 with your county appraisal district by April 30 of the tax year. This is a permanent, ongoing benefit — one of the most valuable solar incentives available to Texas homeowners in 2026.
Texas law allows businesses to deduct the full cost of a qualifying solar energy device from their state franchise tax. This incentive is designed for commercial and business entities — not individual residential homeowners — and can meaningfully reduce the upfront cost of a commercial solar installation.
Qualifying solar energy devices include systems that convert solar energy into thermal, mechanical, or electrical energy, as well as systems that store or distribute that converted energy. This makes both solar PV systems and solar thermal installations eligible for the deduction.
Businesses considering a solar installation in San Antonio should consult a tax professional to determine how this deduction interacts with other business tax strategies. For more details, visit the Texas Comptroller’s franchise tax page or contact the Comptroller’s office directly.
Tesla Electric offers a Virtual Power Plant (VPP) program for Powerwall owners in select areas of CenterPoint’s service territory in Texas. Participants receive a $10 per month electric bill credit in exchange for allowing Tesla to discharge their Powerwall’s stored energy back to the grid during periods of high demand or grid stress.
To participate, homeowners must use Tesla Electric as their Retail Electricity Provider (REP) and own a Tesla Powerwall battery system. The program is designed to support grid reliability on the ERCOT grid while providing Powerwall owners with a modest ongoing financial benefit that helps offset the cost of their battery investment.
This program is particularly relevant given Texas’ history of grid reliability challenges. Homeowners in San Antonio interested in enrolling should visit Tesla’s website or contact Tesla Energy directly to confirm current eligibility, service territory coverage, and enrollment steps.
Texas has strong solar access protections enshrined in state law that prevent homeowners associations (HOAs), municipalities, villages, and other private entities from prohibiting or unreasonably restricting the installation of rooftop solar panels. This means that even if your HOA has aesthetic guidelines, it cannot outright ban solar installations on your home.
While HOAs may still impose reasonable restrictions related to placement or appearance — such as requiring panels not to be visible from the street — they cannot use these rules as a de facto ban on solar. This protection gives homeowners in San Antonio the legal right to go solar regardless of their HOA’s preferences, removing a common barrier to adoption.
If you believe your HOA is unlawfully restricting your ability to install solar panels, you may wish to consult the relevant sections of the Texas Property Code or seek legal advice. This protection applies statewide and is an important foundational right for all Texas solar homeowners.

Leasing Solar Panels
San Antonio homeowners are served by CPS Energy, and it’s important to know upfront: CPS Energy is one of the few utilities in Texas where Palmetto’s LightReach third-party ownership (TPO) program — including both leases and PPAs — is currently not available. If you’re in San Antonio and want to go solar with Palmetto, a cash purchase or solar loan is your path forward.
That said, it’s worth understanding what leasing and PPAs offer, since many Texas homeowners outside San Antonio — and those who may move — have access to them. With a solar lease, you pay a fixed monthly amount (e.g., $125/mo) regardless of how much your system produces. With a solar PPA, you pay per kilowatt-hour generated, so your bill shifts with the seasons. Either way, Palmetto owns and maintains the system — no repair bills, no upkeep on your end. Learn more about the differences here.
For San Antonio homeowners going the cash purchase route, the tradeoff is straightforward: a larger upfront investment, but you own the system outright and capture the full long-term savings. Texas’ 100% property tax exemption on added home value from solar makes ownership even more attractive. Either way, solar in San Antonio is a strong long-term financial decision.
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, solar makes strong sense in San Antonio. The city averages 5.4 peak sun hours per day, Texas electricity rates have risen 23% since 2021, and a typical San Antonio home can save around $79,000 over 25 years with solar. Texas also offers a 100% property tax exemption on the added home value from a solar installation.
For homeowners concerned about upfront costs, Palmetto’s LightReach solar lease removes that barrier entirely — you can go solar with no money down and start saving from day one. Note that LightReach is currently not available through CPS Energy, so San Antonio homeowners would pursue a cash purchase or solar loan.
Yes, San Antonio has net metering. San Antonio is served by CPS Energy, which offers a Monthly Net Metering program. Excess energy your solar panels send to the grid earns credits that carry over month to month as a dollar amount — approximately 2 cents per kWh from June through September and 1.65 cents per kWh from October through May.
One important detail: any unused credits accumulated throughout the year are forfeited each December without a cash payout. This makes it worth sizing your system to match your actual usage, so you’re not consistently over-producing and losing credits at year-end.
Yes, solar panels can increase your home value in San Antonio. According to a Zillow study, homes with solar panels sell for approximately 4.1% more than comparable homes without them. On a $300,000 San Antonio home, that could mean roughly $12,300 in added value.
Texas makes this even more attractive with a 100% property tax exemption on the added home value from a solar installation — meaning you gain the value without paying higher property taxes on it.
With Palmetto’s LightReach lease, San Antonio homeowners can go solar for a low fixed monthly payment — starting around $89–$167/month depending on home size — with no upfront cost. Palmetto owns and maintains the system, so there’s nothing out of pocket to get started.
For a cash purchase, a typical San Antonio system runs $20,000–$36,000 depending on system size. Note that the federal 30% tax credit is no longer available for residential cash purchases following the Big Beautiful Bill. Use the calculator above for a personalized estimate.
For many San Antonio homeowners, solar is worth it financially — especially with a lease option. With Palmetto’s LightReach lease, your monthly payment is typically less than your current electricity bill, meaning you can start saving from day one with no upfront investment.
For those who purchase outright, a typical San Antonio system pays for itself in about 10–11 years and can generate roughly $79,000 in savings over 25 years — all while Texas electricity rates continue to rise.
Palmetto Solar is a strong choice for San Antonio homeowners. As a national company with a local focus, we’ve completed 3,810 installs across Texas since 2020 — backed by a trusted install network and some of the best financing options in the industry.
We offer both cash purchase and solar loan options for San Antonio residents served by CPS Energy. Our team handles everything from design to installation, and our 90% Production Guarantee and comprehensive protection program give homeowners long-term peace of mind.
With Palmetto’s LightReach lease, there is no upfront cost. You pay one simple monthly payment that covers the system, installation, monitoring, maintenance, and a 90% Production Guarantee. For a typical 9.72 kW system in San Antonio, the estimated monthly lease payment is approximately $125/month — often less than your current electricity bill, so savings can start immediately.
Because Palmetto owns the system, it claims the commercial Investment Tax Credit (ITC) and passes those savings to you through lower monthly payments — an advantage over cash purchases, where the residential ITC was eliminated by the Big Beautiful Bill. Note that LightReach is currently unavailable through CPS Energy, so San Antonio homeowners would pursue a cash purchase or solar loan instead.
