Solar Panels in Texas (TX)

The average cost of an 8 kW solar system in Texas is approximately $24,000 ($3.00/watt installed). Note: The federal residential solar tax credit (Section 25D) was repealed in early 2026, so the full system cost applies unless state incentives are available. State-level incentives may reduce your out-of-pocket cost. Get 3-5 quotes from local installers for accurate pricing.

The federal residential solar tax credit (Section 25D) was repealed in early 2026. Homeowners who installed solar before the repeal can still claim the credit for that tax year. Commercial solar projects continue to receive the 30% ITC under Section 48/48E. Texas still offers state-level incentives that can reduce your solar costs. Consult a tax professional for the latest guidance.

Texas has no statewide net metering law, but the deregulated ERCOT electricity market means retail electricity providers (REPs) compete to offer solar buyback plans. Rates range from $0.04/kWh to full retail credit depending on the provider. Compare plans on PowerToChoose.org. Municipal utilities like Austin Energy and CPS Energy have their own solar programs with different terms.

An 8 kW solar system in Texas produces approximately 12,400 kWh/year, saving about $1,736 annually at the average electricity rate of $0.14/kWh. The estimated payback period is 13.8 years. Over 25 years, total savings can reach $43,400.

No Statewide Net Metering Mandate: Texas has no statewide net metering requirement. In the deregulated ERCOT market, some retail electricity providers (REPs) offer solar buyback plans at varying rates. Oncor, CenterPoint, and AEP service areas have multiple REP options for solar export credits. Municipal utilities (Austin Energy, CPS Energy) have their own programs. Buyback rates range from $0.04 to full retail depending on the provider and plan.

Our top pick for Texas is the REC Alpha Pure-RX 470W (22.6% efficiency, -0.24%/°C temp coefficient). HJT technology with -0.24%/°C temp coefficient is critical for Texas heat. Excellent hail resistance with robust build quality. 22.6% efficiency maximizes output.

The estimated payback period for an 8 kW solar system in Texas is 13.8 years. This is calculated as: system cost ($24,000) divided by annual savings ($1,736/year). After payback, solar generates essentially free electricity for 15-20+ more years. State incentives may shorten this further.

Battery storage is strongly recommended in Texas because export credits are lower than the retail electricity rate. A battery lets you store excess solar for evening use, maximizing self-consumption and savings. With the residential ITC repealed, battery costs are no longer offset by the federal credit, but batteries remain valuable for backup power and savings optimization.

Yes, Texas offers state-level solar incentives: Property Tax Exemption (100% exemption on added value), Austin Energy Solar Rebate (Up to $2,500 rebate), CPS Energy Solar Rebate (San Antonio) (Varies by program year), Solar Buyback Plans (ERCOT) (Export credits from retail providers). Note that the federal residential solar tax credit (Section 25D) was repealed in early 2026. Check the DSIRE database for the latest program details.
