Texas Solar Incentives 2026: Rebates, Tax Exemptions & Utility Programs

Texas has quietly become the second-largest solar market in the United States, trailing only California. In 2025, Texas added more than 7 gigawatts of new residential and commercial solar — and 2026 is on pace to surpass that record. If you're a Texas homeowner considering solar, the incentive picture looks different here than in most states: there's no state income tax (which means no state solar tax credit), but a powerful combination of the federal Investment Tax Credit, a complete property tax exemption, and some of the most generous utility rebate programs in the country can still cut your net system cost by 40–55%.

This guide breaks down every Texas solar incentive available in 2026, with real dollar estimates, utility-specific programs, and the one reason Texas homeowners may need battery storage more than anyone else in the country.

The Federal Investment Tax Credit: 30% Off Every Texas Installation

The federal 30% Investment Tax Credit (ITC) is the foundation of any Texas solar financial plan. It applies nationwide, and because Texas has no competing state tax to reduce its value, it's especially impactful here.

For a typical Texas solar system:

System Size	Gross Installed Cost	30% ITC Value	Net Cost After ITC
6 kW	$18,000	$5,400	$12,600
8 kW	$23,500	$7,050	$16,450
10 kW	$28,500	$8,550	$19,950
13 kW	$36,000	$10,800	$25,200

2026 ITC key rules:

• Applies to panels, inverters, battery storage, wiring, and installation labor
• Claimed on federal Form 5695 when you file your tax return
• Reduces your tax bill dollar-for-dollar — not just a deduction
• If your credit exceeds your tax liability, unused credit rolls forward to future years
• Available through 2032 at the full 30% rate; steps down to 26% in 2033

Battery storage added alongside or after a solar installation qualifies for the same 30% ITC under the Inflation Reduction Act. This is a significant factor in Texas given the 2021 winter storm (Uri) and ongoing grid reliability concerns — see the battery section below.

Texas Property Tax Exemption: 100% on the Added Home Value

This is one of the most valuable state-level solar incentives in the country, and it's permanent Texas law.

Texas Tax Code Section 11.27 exempts 100% of the added appraised value that solar panels add to your home from property taxes. In a state with no income tax but relatively high property tax rates (averaging 1.6–2.0% of home value), this benefit is substantial.

How it works:

• Your county appraisal district assesses your home value
• Solar panels typically add $15,000–$35,000 to appraised home value (depending on system size and local real estate market)
• Without the exemption: that added value × your property tax rate = annual tax increase
• With the exemption: $0 additional property tax, ever, for as long as you own the system

Dollar example for a Dallas homeowner:

• 10 kW solar system adds $25,000 to appraised home value
• Dallas County property tax rate: approximately 2.1%
• Annual tax savings: $25,000 × 2.1% = $525/year
• Over 25-year system life: $13,125 in cumulative tax savings

To claim the exemption, file a one-time application with your county appraisal district after installation is complete. Forms are available through your county's appraisal district website. No annual renewal required.

Texas Sales Tax Exemption on Solar Equipment

Texas exempts solar energy equipment from the state 6.25% sales tax under Texas Tax Code Section 151.328. This applies to:

• Solar panels
• Inverters
• Mounting hardware
• Batteries used with solar systems
• Installation labor (partially exempt)

Dollar impact: On a $25,000 installed system, the 6.25% sales tax exemption saves approximately $1,560 at point of purchase. Most reputable Texas solar installers apply this automatically — confirm your quote excludes sales tax on equipment.

Utility Rebate Programs in Texas: City-Owned Utilities Lead the Way

Because Texas operates on the ERCOT grid (largely isolated from the national grid), the state's electricity market is deregulated for most residents. However, several large city-owned utilities still offer significant solar rebates.

Austin Energy: $2,500 Rebate + Performance Incentives

Austin Energy's residential solar program is the most generous in Texas. In 2026, the program includes:

Upfront rebate: $2,500 flat for systems installed through an Austin Energy Participating Contractor — one of the highest flat rebates from any U.S. utility.

Value of Solar Tariff (VoST): Austin Energy uses a unique export rate based on the long-run value of solar to the grid (fuel savings, capacity value, environmental benefit). The VoST rate in 2026 is approximately $0.097/kWh for exported energy — higher than the standard retail rate in many cases. This is credited to your bill monthly.

Eligibility requirements:

• Must be an Austin Energy customer (within Austin city limits)
• System must be installed by an Austin Energy Participating Contractor
• Rebate application submitted after installation inspection passes

Total incentive stack for an 8 kW system in Austin:

• Federal ITC: $7,050
• Austin Energy rebate: $2,500
• Sales tax exemption: ~$1,400
• Property tax exemption (lifetime): ~$10,500
• Total incentives: ~$21,450 on a $23,500 gross cost = net cost of ~$2,050

CPS Energy (San Antonio): Rebates Up to $1,200

CPS Energy — the municipal utility serving San Antonio — offers residential solar customers:

Solar rebate: $0.10 per watt for systems up to 15 kW, capped at $1,200. An 8 kW system earns the full $1,200.

Net metering: CPS Energy credits excess generation at the avoided cost rate (approximately $0.045/kWh), which is lower than retail but still meaningful for oversized systems.

Requirements: Installation must use CPS Energy-approved equipment; application submitted before installation begins.

El Paso Electric: Solar Net Metering

El Paso Electric offers one-to-one net metering credits for residential solar customers — meaning every kWh exported to the grid earns a full retail credit (~$0.13/kWh) on your next bill. No upfront rebate, but the favorable export rate means an appropriately sized system (110% of your usage) can effectively zero out your bill.

Deregulated Market Areas (Dallas, Houston, Most of Texas)

If you're in the deregulated ERCOT market (most of the DFW Metroplex, Houston, and suburban Texas), your retail electricity provider sets export rates, not the utility. Rates vary by provider:

• Some providers (Green Mountain Energy, Reliant) offer 1:1 net metering-equivalent credits
• Others credit exports at a lower rate ($0.03–0.07/kWh)
• Recommendation: Before signing a solar contract, compare retail electricity plans at PowerToChoose.org and select a provider with the best solar export terms. Switching providers is easy in deregulated Texas — typically just a contract change.

Why Battery Storage Is Especially Valuable in Texas

The February 2021 winter storm (Uri) left 4.5 million Texas homes without power for days, some for more than a week. The 2022–2024 summers brought additional near-miss grid failures during extreme heat. ERCOT's isolated grid cannot import power from neighboring states during emergencies.

For Texas solar owners, battery backup provides resilience that simply isn't available to Texas homeowners without storage:

Typical battery costs after incentives:

• Tesla Powerwall 3 (13.5 kWh): $12,000–$14,000 installed
• Enphase IQ 5P (5 kWh): $8,000–$10,000 installed
• After 30% ITC: $8,400–$9,800 (Powerwall) or $5,600–$7,000 (Enphase)

Battery backup for essential loads: During a grid outage, a single 13.5 kWh battery can power your refrigerator, lights, phone chargers, and Wi-Fi for approximately 24–48 hours. Paired with your solar array, your battery recharges each day as long as sun is available — effectively unlimited backup during extended outages.

Low-Income Solar Programs in Texas

LoanSTAR Program (State Energy Conservation Office)

The Texas State Energy Conservation Office (SECO) operates LoanSTAR — low-interest loans for energy efficiency and renewable energy improvements for local governments, schools, hospitals, and nonprofits. If you own or operate a qualifying facility, LoanSTAR financing offers rates as low as 3% for solar installations.

Weatherization Assistance Program (WAP)

The federal WAP program provides free weatherization services (including solar-ready electrical upgrades) to Texas low-income households at or below 200% of the federal poverty level. WAP is administered through local Community Action Agencies in Texas. While WAP doesn't install solar panels directly, it can prepare your home's electrical system for future solar installation at no cost.

USDA Rural Energy for America Program (REAP)

Texas has a large rural population, and the USDA REAP program provides grants covering up to 50% of solar installation costs for agricultural producers and rural small businesses. In 2026, REAP grant funding available to Texas applicants exceeds $50 million. Eligible entities include farms, ranches, rural retail businesses, and rural service providers with primary operations in rural areas.

For full details on federal grant programs, see our solar panel grants guide.

How Texas Solar Incentives Stack in 2026

Here's what a complete incentive stack looks like for a typical Houston homeowner (deregulated market, no utility rebate):

System: 10 kW solar + 13.5 kWh battery backup Gross installed cost: $38,000

Incentive	Value
Federal ITC (30% of $38,000)	$11,400
Texas sales tax exemption	$2,375
Property tax exemption (25-year lifetime)	$15,600
Total incentives	$29,375
Net effective cost	$8,625

With a payback period of 7–9 years (depending on electricity rates and system performance), and 25 years of projected savings of $65,000–$85,000, Texas solar + storage delivers strong ROI even without utility rebates.

Austin homeowners with access to the $2,500 Austin Energy rebate push the net cost even lower — in some cases under $5,000 for a fully financed-to-zero system after incentives.

Applying for Texas Solar Incentives: Checklist

1. Get 3 quotes from Texas-licensed solar installers. Compare cost per watt, equipment brands, and warranty terms. For help selecting a contractor, see our best solar companies guide.

2. Verify Austin Energy or CPS Energy eligibility if you're in Austin or San Antonio. Request that your installer apply for the utility rebate before or immediately after installation.

3. File the property tax exemption with your county appraisal district after installation is complete. Bring your permit/inspection documentation.

4. Confirm your retail plan allows solar net metering if you're in the deregulated market. Switch plans if needed before your system goes live.

5. Claim the federal ITC on your federal tax return for the year installation was completed. Use IRS Form 5695. Confirm with a tax advisor if your tax liability is close to the credit amount.

6. Consider battery storage — especially if you're in ERCOT's territory, where blackout resilience requires local storage. The 30% ITC on batteries makes this the lowest-cost it has ever been.

Texas Solar Outlook for 2026

Texas's solar market is growing faster than any other state. The combination of abundant sunshine (Dallas averages 5.5–6.0 peak sun hours per day; Houston averages 4.8–5.3), high electricity rates in deregulated markets ($0.13–0.17/kWh retail), no state income tax complicating credit planning, and a complete property tax exemption make Texas one of the strongest financial cases for solar in the country.

The 2021 winter storm and ongoing summer heat waves have shifted Texas homeowner attitudes: energy independence is now a priority beyond just economics. Solar + storage gives Texas households what the grid cannot guarantee: power that stays on.
