Solar Panels in Texas: Cost, Payback & ROI (2026)

Is solar still worth it in Texas after the 30% federal tax credit expired? These pre-computed estimates use NREL PVWatts production data and current 14.2¢/kWh Texas electricity rates for a typical home using 900 kWh/month.

Section 25D (30% federal solar tax credit) expired December 31, 2025

All numbers below reflect 2026 math with no federal residential credit. State incentives, where applicable, are noted in the section below.

Is Solar Worth It in Texas in 2026?

Texas has an outstanding solar resource (1,650 kWh/kW/year) and moderate electricity rates of 14.2¢/kWh, which create solid but not exceptional economics. Unlike most states, Texas has no state solar income tax credit or statewide rebate program. However, several utilities offer their own incentives: Austin Energy provides a $2,500 rebate, and CPS Energy (San Antonio) has historically had a rebate program. The ERCOT grid's volatile pricing makes battery storage increasingly attractive.

For a typical Texas home consuming 900 kWh per month, our calculation shows a 6.5 kW system needed for 100% offset. At the current national average installed cost of $2.95/W (LBNL Tracking the Sun 2024), that's $19,309 gross before any state rebates. Year-one savings of $1,534 grow each year as electricity rates escalate — the model assumes 2.5%/year (EIA AEO 2024).

The 11.3 years payback period is moderate — within the national average range of 8–12 years. Over 25 years — the standard warranty period for most premium panels — a Texas homeowner following this profile would save an estimated $49,043 total, for a net benefit of $29,734 after recovering the system cost.

Solar Incentives in Texas (2026)

Texas's main statewide solar benefit is a property tax exemption on the added home value — you pay no additional property tax on the value solar adds to your home.

  • Property tax exemption on added home value (statewide)
  • Austin Energy rebate ($2,500 for qualifying systems)
  • CPS Energy rebate program (San Antonio, check availability)
  • Oncor and other utility solar programs (vary by territory)

Incentive programs change frequently. Verify current offerings at dsireusa.org or directly with your utility before making any purchasing decision.
