Solar Panels in Texas: 2026 Costs, Incentives, and Buyback Plans
What defines solar economics in Texas is the deregulated ERCOT market: there is no statewide net metering, so your savings depend almost entirely on which retail electric provider's "solar buyback" plan you choose, or on your municipal utility's rules if you are in Austin, San Antonio, or a co-op. Strong sun (roughly 5 to 6 peak hours a day) and a 100% property tax exemption on the added home value help, but the loss of the federal residential credit for owned systems placed in service after December 31, 2025 has pushed typical payback longer. The right buyback plan, not the panels, is usually the single biggest variable in a Texas solar bill. These figures are general information, not tax advice; confirm current details with each program and a licensed tax professional.
Solar incentives in Texas
State, utility, and local programs that can lower the cost of going solar here. Availability and amounts change, so verify each before counting on it.
| Program | Type | What to know |
|---|---|---|
| Texas Solar Property Tax Exemption (Tax Code Sec. 11.27) | State | The added home value from a solar system is 100% exempt from property tax. This typically requires a one-time application (Form 50-123) filed with your county appraisal district, often by the April 30 deadline; verify current availability and filing rules with your county appraisal district. |
| Retail Electric Provider (REP) Solar Buyback Plans | Utility | In deregulated ERCOT areas, competing REPs offer plans that credit exported energy at varying rates (retail-match, fixed-credit, or wholesale), so the plan you pick largely sets your savings; compare current offers since rates and structures change often and most providers have moved away from one-to-one retail credit. |
| Austin Energy Solar Photovoltaic Rebate | Local | Austin Energy customers may qualify for a residential rebate (currently $2,500) after completing its solar education course and installing a qualifying system, alongside its Value of Solar tariff that credits exports; verify current availability, course requirements, and funding before counting on it. |
| Austin Energy Value of Solar (VoS) Tariff | Local | Instead of net metering, Austin Energy bills you the retail rate for all the power you use and separately credits everything your system produces at a per-kWh Value of Solar rate set annually (about 9.91 cents in 2026), applied as a bill credit rather than a one-for-one offset; confirm the current VoS rate with Austin Energy. |
| CPS Energy (San Antonio) Solar Bill Credits | Local | CPS Energy credits solar generation toward your bill under a net billing structure, with exports above your monthly usage credited at a much lower rate than retail. Its residential upfront rebate is no longer offered, so confirm current program terms and any business or nonprofit incentives before you sign. |
| Commercial Credit for Leased / PPA Systems (Section 48E) | Federal | If you lease or sign a power purchase agreement, the third-party owner may be able to claim the commercial clean energy credit (Section 48E, which under current law applies to qualifying solar placed in service through 2027) if the project qualifies, which can affect your quoted price; this is not guaranteed and does not apply to systems you buy or finance yourself. |
Net metering in Texas
No statewide net metering; REP buyback plans. Texas does not mandate net metering. Because the ERCOT market is deregulated, the delivery utility (Oncor, CenterPoint, AEP Texas, or TNMP) only moves power and does not buy your exports, so credit for excess solar comes from your retail electric provider's chosen buyback plan. Most providers have moved away from one-to-one retail credit toward fixed-credit or wholesale-rate plans, which means two homeowners with identical systems can see very different payback depending on the plan, so comparing buyback offers is the most important step in Texas. Municipal utilities like Austin Energy (Value of Solar) and CPS Energy (net billing), plus electric co-ops, set their own export rules rather than following a single statewide standard.
Going solar in Texas: what shapes the numbers
The local factors that move payback and savings most.
What moves payback in Texas: the buyback plan, not just the panels
In most of the state you buy electricity from a retail provider, not the wires company, so the rate you are credited for exported solar is set by whichever buyback plan you sign up for. Some plans credit exports near the retail rate, while others use a lower fixed credit or a wholesale rate that can swing with the market. Because of this, two neighbors with the same roof and the same system can have very different payback timelines. Estimated payback in Texas commonly lands around 9 to 14 years in 2026 and varies by utility, plan, and usage. Treat the buyback plan as a core part of the purchase decision, not an afterthought.
Sun and production: strong, but it varies west to east
Texas is one of the better solar states, with roughly 5 to 6 peak sun hours a day across much of the state. The drier western half tends to see more peak sun than the humid Gulf Coast, so a system in West Texas or the Panhandle often produces more per panel than the same system near Houston, where averages sit closer to 4.7 hours. Dallas and Austin fall in between, around 5.2 to 5.4 hours. More production shortens payback, which is part of why estimates differ so much by city. Summer output is high, but heat can slightly reduce panel efficiency on the hottest afternoons.
Financing after the 2025 federal change
The federal residential solar credit (Section 25D) was terminated for systems placed in service after December 31, 2025, so a Texas homeowner who buys or finances a system in 2026 should not expect a 30% federal tax credit. That single change lengthens typical payback compared with prior years and makes the state property tax exemption and your buyback plan matter even more. If you lease or sign a PPA, the company that owns the system may be able to use the commercial credit, which can influence your quoted rate, but that is the owner's benefit and is not guaranteed. Confirm current eligibility for any incentive with the program administrator and a licensed tax professional.
Roof, climate, and storage in Texas
Texas weather shapes the system you actually want. Hail in North and Central Texas, high heat, and Gulf Coast hurricane exposure all argue for quality racking, wind-rated mounting, and good warranties rather than the cheapest bid. Many Texans also add battery storage, partly for resilience after grid stress events and partly because, without one-to-one net metering, storing your own power can be worth more than exporting it for a low credit. Whether a battery pencils out depends on your buyback plan and usage, so price systems with and without storage.

Local considerations for Texas homeowners
Conditions and rules that tend to come up when going solar in this state.
- No statewide net metering: your savings hinge on the retail provider's buyback plan, which can change at renewal.
- Delivery utility (Oncor, CenterPoint, AEP Texas, TNMP) only moves power and does not credit exports; the REP does.
- Municipal utilities (Austin Energy, CPS Energy) and co-ops set their own export and rebate rules, separate from ERCOT REPs.
- 100% property tax exemption on added home value (file Form 50-123 with your county), but sales tax still applies to equipment in most cases.
- Hail and high heat in North and Central Texas favor durable equipment and strong warranties over the lowest bid.
- Gulf Coast wind and hurricane exposure make wind-rated mounting and proper permitting important near the coast.
- After grid stress events, many homeowners weigh battery storage for resilience, not just bill savings.
- Texas has no statewide solar-rights law as strong as some states, so confirm HOA rules before signing.
Before you sign a Texas solar contract
Questions worth asking any installer before you commit:
- Which retail electric provider buyback plan do you recommend for my delivery area, and how is each exported kWh credited?
- Is the buyback credit a retail match, a fixed credit, or a wholesale rate, and can it change when I renew my electricity plan?
- If I am in Austin Energy or CPS Energy territory, how will the Value of Solar tariff or net billing credits apply to my account?
- Given hail and heat in my part of Texas, what panel, inverter, and racking warranties come with this system?
- Will you help me confirm the property tax exemption (Form 50-123) with my county appraisal district, and is any local permitting or HOA approval required?
- Can you quote the system both with and without battery storage so I can compare payback under my buyback plan?

Solar in Texas: frequently asked questions
Does Texas have net metering in 2026?
No. Texas has no statewide net metering. In the deregulated ERCOT market, credit for exported solar comes from your retail electric provider's solar buyback plan, and municipal utilities like Austin Energy (Value of Solar) and CPS Energy (net billing) set their own export rules. Comparing buyback plans is the most important step for a Texas homeowner.
Can I still get a 30% federal tax credit for solar in Texas?
Not for a system you buy or finance. The federal residential credit (Section 25D) was terminated for systems placed in service after December 31, 2025. A company that owns a leased or PPA system may be able to use the commercial credit if the project qualifies, but that is not guaranteed and is the owner's benefit. Confirm current rules with a licensed tax professional.
How much do solar panels cost in Texas?
Installed prices in 2026 typically run about $2.20 to $3.00 per watt before any incentives, so a mid-size system commonly falls in the mid five figures. Your final number depends on system size, equipment, roof complexity, and installer. These are typical ranges, not quotes, and actual costs vary.
What is the payback period for solar in Texas?
Estimated payback commonly lands around 9 to 14 years in 2026, longer than in prior years because the federal residential credit no longer applies to owned systems. Your actual timeline depends heavily on your buyback plan, electricity usage, local sun, and system cost, so treat any single number as an estimate.
Is there a property tax increase for adding solar in Texas?
No. Under Texas Tax Code Section 11.27, the added home value from a solar system is exempt from property tax. This typically requires a one-time application (Form 50-123) filed with your county appraisal district, often by the April 30 deadline. Confirm current filing requirements with your local appraisal district, since procedures can vary.
Should I get a battery with solar in Texas?
It depends on your buyback plan and goals. Because Texas lacks one-to-one net metering, storing your own power can sometimes be worth more than exporting it for a low credit, and many homeowners value batteries for resilience after grid stress events. Ask your installer to price the system with and without storage so you can compare payback.
