Texas Solar Incentives, Cost & Savings (2026)
Written by Aditya Patil · Last updated 2026-09-24
Texas gets more sun than most states and has some of the highest average electricity bills in the country — yet it has no statewide net metering law. Understanding who buys your exported power (a REP, Austin Energy, CPS Energy, or a co-op) is the single most important step before signing anything.

Cost of solar in Texas
Texas's real median installed residential cost is $3.85/watt, from LBNL's Tracking the Sun public data file (host-owned residential systems, 2023–2024). A typical installed system in Texas is 8 kW with a typical gross cost of $31,486 — that works out to about $3.94/watt for a typical-sized job, which is close to the $3.85/W headline median but not identical: the headline is the median price per watt across all installations LBNL recorded, while the typical size and typical gross cost are each their own separate median.
For a Texas household at the state average of 15,713 kWh/year, a system to cover 100% of that usage would be roughly 10.6 kW, costing about $40,749 before any incentives. There is no federal residential clean energy credit (§25D) for systems completed after December 31, 2025, so the 2026 net cost for a cash or loan purchase is the same $40,749.

Incentives & rebates
| Program | Amount | Status |
|---|---|---|
| Solar and Wind-Powered Energy Device Property Tax Exemption | 100% exemption of the increase in a property's appraised value that is attributable to installing a solar (or wind) energy device used to produce or store energy for on-site use. | open |
| Austin Energy Residential Solar Rebate | $4,000 flat rebate per qualifying residential solar project (increased from $2,500, effective July 1, 2026 — a 60% increase per Austin Energy's own announcement). | open |
| Austin Energy Power Partner Battery Program | $500 one-time rebate per enrolled battery system after Permission to Operate (PTO), plus an estimated ongoing performance payment of about $75/kW of battery capacity per year (Austin Energy estimates roughly $324/year for a typical Tesla Powerwall) for allowing Austin Energy to dispatch stored energy during up to 40 demand-response events/year, each lasting about 2-3 hours; battery reserve is not drawn below 20%. | open |
Sales tax: None for typical homeowners. Standard Texas state sales tax (6.25%) plus local taxes (up to 2%, max combined 8.25%) applies to residential solar panels, batteries, and installation labor. A narrow exemption under Tax Code Section 151.318 (manufacturing exemption) applies only to specific utility-scale/commercial solar generation-facility equipment (e.g., panels and DC-to-AC collection equipment), per Comptroller Policy Letter Ruling No. 201907005L (July 8, 2019) — and that ruling explicitly excludes racking/support structures even at utility scale. It does not create any residential exemption.
Net metering & export rules
Texas is the most complicated state for solar export policy in the country — not because the rules are hidden, but because there is no single rule. The PUCT does not require any utility or REP to buy power from solar customers. About 85% of Texas falls inside the ERCOT deregulated market, where the wires-only transmission and distribution utility (TDU — Oncor, CenterPoint, AEP Texas, or Texas-New Mexico Power) handles interconnection paperwork, but your Retail Electric Provider sets any export credit. Only some REP plans include a solar buyback option; rates and plan availability change frequently.
If you live in Austin or San Antonio, you are served by a municipal utility — Austin Energy or CPS Energy — that is not part of the deregulated retail market and runs its own solar compensation program. Outside ERCOT, El Paso Electric is a PUCT-regulated investor-owned utility with its own net metering tariff (tightened July 1, 2025). The rest of the state is served by electric cooperatives, each with its own interconnection tariff.
| Statewide mandate | None — Texas has no PUCT-mandated solar buyback rate |
| ERCOT (deregulated, ~85% of TX) | Your Retail Electric Provider (REP) sets the export rate; buyback plans range ~3–6¢/kWh on most fixed plans |
| Austin Energy (CoA municipal) | 9.91¢/kWh Value of Solar (VoS) — verify after Oct 1, 2026 for expected 12.88¢ update |
| CPS Energy (San Antonio) | Sells excess to CPS Energy directly; per-kWh rate not publicly published — contact CPS Energy |
| El Paso Electric (outside ERCOT) | Own net metering tariff; new systems (post-Jul 1 2025) credited at avoided cost, exports capped ~10% of prior-year usage |
| Electric cooperatives | Each co-op sets its own interconnection tariff and buyback rate independently |
| Key action | Ask your utility or REP which entity actually buys your exported power — it changes the math entirely |
In deregulated TDU territory, REP solar buyback rates range roughly 3-6 cents/kWh on fixed-rate buyback plans, up to 'retail-match' (roughly 1:1 credit) on a handful of premium plans (e.g., TXU Energy's Solar Buyback plans span about 3.5-6 cents/kWh, with a retail-match option in Oncor territory) — verify current rates via each REP's EFL before publishing a number. Austin Energy's official Value of Solar (VoS) rate is 9.91 cents/kWh for systems under 1 MW-AC, effective March 1, 2023 per its own published rate page; multiple secondary sources (SolarAustin, dated 2026-07-29) report Austin Energy raising VoS to 12.88 cents/kWh effective October 1, 2026, which was not yet reflected on Austin Energy's own rate page as of 2026-09-22 — re-verify after that date. CPS Energy customers may only sell excess generation back to CPS Energy itself (per CPS Energy's own solar FAQ), not to a third party or REP, but CPS Energy has not published a specific per-kWh buyback figure findable in this research; flagged as unverified.
Top utilities
| Utility / REP | Residential rate | Customers |
|---|---|---|
| Reliant Energy Retail Services | 17.38¢/kWh | 1,548,250 |
| TXU Energy Retail Co, LLC | 18.7¢/kWh | 1,446,391 |
| City of San Antonio - (TX) | 12.43¢/kWh | 865,914 |
Residential rate and customer counts are from EIA-861. In ERCOT's deregulated market, REPs like Reliant and TXU set their own retail rates — the figures above are averages across their customer base and will differ from any specific plan rate you see on an Electricity Facts Label (EFL).
Batteries & VPP programs
Texas has stronger economic and resilience arguments for home battery storage than almost any other state. Economically, the low REP solar buyback rates (3–6¢/kWh) mean the less you export, the better — and a battery lets you use your own solar production rather than selling it cheaply. For resilience, the ERCOT grid's history of weather-related stress events has made backup power a tangible priority for many homeowners.
Austin Energy Power Partner Battery
$500 enrollment rebate plus ongoing annual performance payments (~$75/kW, roughly $324/year for a typical Powerwall) for Austin Energy customers with an eligible, customer-owned home battery who allow Austin Energy to dispatch it during demand events (capped at 40 events/year).
Base Power
Not a utility rebate but a market-based model worth flagging for TX battery content: Base Power supplies a home battery at low/no upfront cost bundled with its retail electricity service, recovering hardware cost through ERCOT market (VPP) revenue rather than a government or utility incentive.
CPS Energy — no residential battery incentive
CPS Energy's own solar FAQ states there are 'no incentives available for the battery portion' of a residential solar+storage system, even where the solar portion is otherwise rebate-eligible. Noted here explicitly to avoid readers assuming San Antonio has a battery rebate.
ERCOT Aggregate Distributed Energy Resource (ADER) Pilot Project
A PUCT-established (Project No. 53911), ERCOT-run pilot allowing many small distributed resources — primarily residential batteries, solar+storage, and controllable loads — to be aggregated by a Qualified Scheduling Entity into a single dispatchable resource that participates in the ERCOT wholesale market. Originally targeted 80 MW; as of the most recent public reporting it is in Phase 3 (expanded capacity limits, lower barriers to entry for aggregators). Tesla (aggregating residential Powerwalls in the Oncor/Dallas and CenterPoint/Houston areas) and Bandera Electric Cooperative are among the active participants, alongside newer entrants like Base Power.
Tesla Electric Virtual Power Plant (Powerwall)
Tesla's Texas retail electricity plan (a licensed REP) automatically enrolls eligible Powerwall owners in a VPP that dispatches stored battery energy into the ERCOT market via the ADER pilot; participants are reported to earn a bill credit plus 'Sellback Credits' for energy exported during dispatch events. Actively expanding across ERCOT service areas through 2026.
Base Power residential battery VPP
Texas-based Base Power provides a subsidized/no-upfront-cost home battery bundled with its own retail electricity plan, then aggregates the fleet into a VPP — charging batteries when ERCOT wholesale prices are low and discharging during evening peaks — with ERCOT market revenue subsidizing the hardware and backup-power service for the homeowner. Confirmed partnerships include a 20 MW VPP with Farmers Electric Cooperative, a 2 MW VPP with Guadalupe Valley Electric Cooperative (GVEC), and a residential distributed-energy pilot (up to 10 MW) with El Paso Electric targeting the 2026 summer peak.
Austin Energy Power Partner Battery — VPP dispatch
Austin Energy's own residential battery demand-response and VPP program — see the rebates and battery incentives section for enrollment details and payment amounts.
Lease vs. buy in Texas
With no federal residential tax credit in 2026, the financial argument for buying outright (rather than leasing or signing a PPA) shifts slightly. The commercial clean energy credit (§48E) still applies to businesses and third-party ownership structures, so a lease or PPA company can still claim its own separate credit and may pass some of that savings to you as a lower monthly payment. Texas's property tax exemption only applies to the equipment owner — if you lease the panels, confirm with your installer whether the exemption applies to your situation. See our full lease vs. buy vs. PPA guide for a structured comparison.
Estimate your own numbers
The numbers above use Texas's statewide average usage and rate. Your roof's orientation, your actual monthly usage, and — crucially — your specific REP's export rate will all shift the results. Use the solar calculator with your own bill and any quote you've received.
FAQ
Does Texas have net metering?
No — Texas has no statewide net metering requirement. The Public Utility Commission of Texas (PUCT) does not set a solar export rate. About 85% of Texans live in ERCOT's deregulated retail market, where your Retail Electric Provider (REP) decides whether to offer a solar buyback plan and at what rate — most fixed-rate REP buyback plans pay roughly 3–6¢/kWh, well below the 15.94¢/kWh retail rate you pay for grid power. Austin Energy and CPS Energy (municipal utilities in Austin and San Antonio) and electric cooperatives run their own separate programs with different rates. The first thing to confirm is which entity actually buys your exported power: a REP, a municipal utility, or a co-op.
What incentives are available to Texas homeowners right now?
The main one that applies statewide is the property tax exemption under Texas Tax Code §11.27 — your home's appraised value cannot increase because of the solar installation, which avoids ongoing property tax liability for the life of the system. There is no general residential sales tax exemption (the 6.25–8.25% Texas sales tax applies to panels, batteries, and labor on home systems). If you are an Austin Energy customer, a $4,000 flat rebate (raised from $2,500 in July 2026) and the Power Partner Battery program add meaningful upfront savings. The federal residential clean energy credit (§25D) ended for systems completed after December 31, 2025, so there is no federal tax credit in 2026.
How were the payback numbers on this page calculated?
The estimate uses a household with Texas's average 15,713 kWh/year of electricity usage, sized to a 10.6 kW system at Texas's real $3.85/watt installed cost. Solar-only assumes 37% self-consumption; solar+battery assumes 65%, since a battery can shift midday solar production to the high-demand evening hours. Exported kWh are valued at 4.5¢/kWh — a conservative midpoint for a generic ERCOT REP buyback plan. Your actual results depend on your REP's export rate, your own usage pattern, and your roof's sun exposure. Use the solar calculator to plug in your own numbers.
Is a home battery worth it in Texas?
Texas is one of the strongest battery markets in the country, for two distinct reasons. First, the ERCOT grid experienced multiple reliability events (Winter Storm Uri in 2021, subsequent summer heat emergencies) that raised awareness of backup power risk — many Texas homeowners value a battery for resilience independent of economics. Second, the high summer A/C load means Texas households use a lot of electricity in the late afternoon and evening, exactly when a battery discharges what it captured from midday solar — maximizing self-consumption when REP buyback rates are low. Austin Energy's Power Partner Battery program adds a $500 enrollment rebate plus ~$75/kW/year in demand-response payments on top of that.
What are VPP programs in Texas, and can I join one?
A Virtual Power Plant (VPP) aggregates many home batteries into a single dispatchable resource that can earn money in the ERCOT wholesale market. Tesla Electric (a licensed REP in Texas) automatically dispatches eligible Powerwalls during ERCOT market events and credits participants' bills. Base Power is a newer Texas company that provides a subsidized home battery bundled with its own retail electricity plan and recovers the hardware cost through ERCOT market revenue. Austin Energy's Power Partner Battery program is a utility-run VPP that dispatches enrolled batteries up to 40 times per year, each event lasting about 2–3 hours, in exchange for enrollment and performance payments.
