Texas is one of the fastest-growing solar markets in the United States — 1 in 10 new solar installs nationwide happens in Texas. The Lone Star State's combination of abundant sunshine, a deregulated energy market, and powerful property tax protections creates a compelling case for going solar in 2026. While there's no state income tax credit, smart Texans are still saving big by stacking federal, utility, and local incentives.
Federal Solar Incentives in Texas
The federal solar tax credit landscape changed significantly in 2026, and Texas homeowners and business owners need to understand the distinction clearly.
For residential homeowners: The 30% residential Investment Tax Credit (Section 25D) expired on December 31, 2025 per the "One Big Beautiful Bill" passed by Congress. Homeowners who install solar in 2026 cannot claim this credit on their federal return.
For businesses and commercial properties: The 30% commercial ITC (Section 48E) remains fully active through 2027. Texas business owners, commercial property owners, and landlords with solar installations still have access to this significant credit.
Texas Property Tax Exemption
One of the strongest solar incentives in Texas is the full property tax exemption for solar installations. Texas law provides a 100% exemption — solar panels add zero to your property tax bill, regardless of how much value they add to your home.
- Exemption rate: 100% of the added value from solar equipment
- How to claim it: File Form 50-123 with your county appraisal district
- Application timing: File before or shortly after installation
- Legacy Energy handles this: We file all property tax exemption paperwork for our customers as part of our standard installation process — no extra steps required from you
On a $30,000 solar system that increases your home's market value by a similar amount, a Texas homeowner at a 2.1% effective property tax rate would otherwise owe an additional $630 per year in taxes. The exemption eliminates this cost permanently.
Texas Net Metering
Texas operates the ERCOT deregulated electricity market, which means there is no statewide net metering mandate. Each utility or retail electricity provider sets its own export rate and credit policy. This makes it especially important to understand your specific utility's program before installing solar.
- Austin Energy: Full retail net metering available — one of the best export policies in the state
- CPS Energy (San Antonio): Value of Solar rate approximately $0.097/kWh — below retail but still meaningful
- Oncor territories (Dallas/Fort Worth): Export credits vary by your chosen retail provider — Legacy Energy identifies the best rate plan for your address
- AEP Texas territories (Houston, West TX): Available through select retail providers — we'll confirm current rates for your specific account
- Georgetown Utility Systems: Full net metering available for Georgetown customers
Legacy Energy maps out your specific utility territory and identifies the retail electricity plan with the strongest solar export credits before your installation — ensuring you maximize bill credits from day one.
Utility Rebates in Texas
Unlike most regulated states, Texas utility rebate programs are driven at the local and municipal level. Here are the key programs available in 2026:
| Utility / Program | Rebate Amount | Notes |
|---|---|---|
| Austin Energy | $2,500 | Residential solar, pre-approval required |
| AEP Texas SMART Source | Up to $6,000 | Residential, capacity-based incentive |
| City of Sunset Valley | $1/watt up to $3,000 | Municipal program, limited availability |
| CPS Energy (San Antonio) | Available | Programs vary — confirm current offering |
| Georgetown Utility Systems | Net metering available | Full retail net metering credits |
Most utility rebate programs in Texas require pre-approval before installation begins. Legacy Energy handles all utility applications and coordination as part of our standard process — missing a pre-approval deadline means missing the rebate.
Commercial Solar in Texas
Texas businesses are in an exceptionally strong position for solar in 2026. The combination of the commercial ITC and Texas's no-state-income-tax environment creates one of the best commercial solar ROI scenarios in the country.
- Federal ITC (Section 48E): 30% of total system cost, fully active through 2027
- MACRS depreciation: 5-year accelerated depreciation schedule on the full system cost (minus 50% of the ITC value), significantly reducing taxable income
- No Texas state corporate income tax: Federal credits drive virtually all the tax benefit — no complex state credit coordination required
- Typical commercial payback: 3–4 years for large industrial and commercial users

Top Cities for Solar in Texas
Texas averages 5.8 peak sun hours statewide — among the highest in the country. The best cities for solar combine strong sunlight with favorable utility programs:
- Austin: Most incentives of any Texas city — Austin Energy rebate + retail net metering + property tax exemption
- San Antonio: CPS Energy Value of Solar rate plus strong property tax protections
- Houston: AEP SMART Source rebate territory, 5.7 peak sun hours
- Dallas/Fort Worth: Oncor territory — export credits available through competitive retail providers, 5.6 peak sun hours
- El Paso: Highest sun hours in Texas at 6.1 average — exceptional solar production potential
Average Savings in Texas
Typical Texas homeowner results in 2026, based on Legacy Energy installations in the state:
- Monthly savings: $120–$280 depending on system size and utility rates
- Average payback period: 7–10 years (shorter in high-rebate areas like Austin)
- 25-year total savings: $40,000–$80,000 with typical utility rate escalation of 3–4% annually
- Property value increase: Studies show solar adds approximately $4–$5 per watt of installed capacity to Texas home values — tax-free under the state exemption
Texas electricity rates have risen steadily since the 2021 winter storm event, and ERCOT's grid dynamics continue to create upward rate pressure. Each year of delay is a year of foregone savings — and Texas homeowners who install now lock in protection against future rate increases for 25+ years.
