# Texas Solar Cost Calculator

> Solar panel cost calculator for Texas, 2026: typical installed prices of $2.50-$3.20 per watt, battery storage costs, and the 30% federal credit's 2025 law change.

## Key facts

- A typical 8 kW residential solar system in Texas costs about $20,000-$25,600 installed in 2026, before incentives, at typical quotes of $2.50-$3.20 per watt.
- 2025 federal legislation ended the 30% residential clean energy credit for property placed in service after December 31, 2025, so 2026 Texas solar buyers must verify eligibility at irs.gov before pricing it in.
- Texas exempts 100% of the home value added by a solar installation from property tax, but has no state income tax credit and no statewide net metering.
