Solar in Texas

Texas has no statewide net metering law. In the deregulated ERCOT market, transmission and distribution utilities (Oncor in Dallas–Fort Worth, CenterPoint in Houston, AEP Texas, and TNMP) deliver power but don't sell it — retail providers do, and each sets its own solar buyback terms. This fragmentation means there is no guaranteed compensation floor for exported energy. Some retail plans credit exports at close to the full retail rate; others pay only the avoided energy cost, which can be a few cents per kWh.

The policy that does apply statewide is the property tax exemption under Tax Code §11.27, which fully exempts the appraised value of solar devices. This is a meaningful benefit in high-property-tax Texas, where reassessment on a $23,000 improvement could otherwise add hundreds of dollars to an annual tax bill. There is no state income tax, so no state-level tax credit is possible.

The municipal utilities operate outside the deregulated market. Austin Energy uses a Value of Solar rate that credits production at a calculated value (typically near retail) while billing consumption separately, and CPS Energy runs its own rebate and net-billing scheme. For grid resilience, the post-Uri appetite for batteries has grown, though Texas offers no dedicated storage incentive comparable to California's SGIP — batteries here are justified on backup-power and arbitrage logic rather than rebates.

Texas averages 5.4 peak sun hours statewide — among the best in the country — with West Texas (El Paso, the Permian Basin) and the Panhandle regularly clearing 6.0. Even the humid Gulf Coast around Houston and Corpus Christi, despite afternoon cloud cover, holds above 5.0 thanks to long summer days. A south-facing array tilted at the latitude (around 25–30°) will maximize annual production, though Texas's largely air-conditioning-driven load makes a flatter or westward tilt attractive for matching the summer afternoon peak.

Because many Texas buyback plans compensate exports at or near retail, system sizing here still rewards maximizing production rather than the self-consumption focus of NEM 3.0 states. A common strategy is to size 10–20% above current consumption to hedge against future EV adoption, heat-pump conversion, or rate increases — surplus production remains valuable so long as the chosen retail plan pays for it. The Texas grid's well-documented volatility (Winter Storm Uri in 2021, summer scarcity events) has also driven strong interest in battery storage purely for resilience, independent of the export economics.

In the municipal utility territories — Austin Energy and CPS Energy in San Antonio — solar is handled through distinct programs rather than retail competition. Austin Energy's Value of Solar tariff separates solar production credits from consumption charges, while CPS offers its own rebates and net-billing structure. Homeowners in those cities should evaluate their municipal program directly rather than shopping retail plans.

Texas solar is comparatively inexpensive at $2.90/W, with a typical 8 kW system landing near $23,200 before incentives — about 20% below the California average and below the national norm. Lower labor costs, a competitive installer market in the major metros, and fewer permitting layers in unincorporated areas keep prices down. The 30% federal credit returns roughly $6,960, and the property tax exemption means the improvement doesn't quietly raise your tax bill the way it might in states without one.

Payback lands around 12.5 years on our 8 kW model, faster than most peer states, driven by the combination of low upfront cost, strong sun, and retail buyback plans that still reward exports. The variability comes from the buyback plan itself: a household on a generous near-1:1 plan can pay back in under a decade, while one on an avoided-cost plan (exporting at $0.04–0.06/kWh) stretches the timeline out several years. This single variable — the retail contract — often outweighs panel choice or system size in determining ROI.

Because there's no state income tax credit, the federal ITC and the property tax exemption are the only structural incentives; everything else hinges on the utility or retail provider. That makes the buyback plan the highest-leverage decision in a Texas solar project, and worth re-shopping periodically as contracts expire.
