How Texas compares

Texas gets more sunlight than 78% of the cities we measure, and its electricity costs more than 42% of states and provinces. Both matter, but not equally: the electricity rate usually matters more, because solar saves money by replacing power you would otherwise buy. A sunny state with cheap power often pays back slower than a cloudy state with expensive power. Why that happens →

What a system costs in Texas

Payback stops improving as systems grow, then gets worse. You can only save on electricity you were going to buy, so once a system covers your usage the extra panels mostly export at a lower rate.

Texas solar incentives

Every US household can claim the 30% federal residential clean energy credit, which is what the "after credit" figures above assume. On a $21,660 system that is $6,498 back. How the credit works →

State, utility and municipal incentives stack on top and change often — Texas may offer rebates, property or sales tax exemptions, or performance payments. We deliberately don't list specific state programmes here because they change several times a year and stale numbers are worse than none. The DSIRE database is the standard reference and is kept current.
