Is solar worth it in Texas in 2026?
With an average electricity rate of 13.8¢ per kWh and 5.6 peak sun hours per day, Texas homeowners are in an excellent position to benefit from solar panels. A typical 10kW system will produce around 16,352 kWh per year — enough to offset a significant portion of a typical Texas home's electricity usage.
At current electricity rates, that production saves approximately $2,256 per year. Over 25 years — the standard panel warranty period — the projected net profit after recouping the system cost is around $35,400.
How much do solar panels cost in Texas?
A 10kW solar system — typical for a Texas home — costs approximately $30,000 before incentives (national average: ~$3,000 per kW installed).
| Cost item | Amount |
|---|---|
| System cost (10kW) | $30,000 |
| Federal 30% ITC | −$9,000 |
| Texas exempts the added value of a solar system from property tax assessments under the Texas Property Tax Code Section 11.27, meaning installing solar does not increase your property taxes. Many Texas utilities and municipalities also offer net metering programs. Austin Energy and CPS Energy have historically offered solar rebates. | Additional savings |
| Net cost (after federal ITC) | $21,000 |
Actual costs vary by installer. Always get at least 3 quotes. Installer labour, roof type and system complexity affect final pricing.

What affects solar savings in Texas?
Every homeowner's solar savings are different. In Texas, the key variables are:
- Electricity rate (13.8¢/kWh): Texas's electricity rate is near the national average. Combined with sun hours and system size, this gives a typical homeowner a solid case for solar investment.
- Peak sun hours (5.6 hrs/day): Texas has excellent solar irradiance. High sun hours mean your panels will produce more energy per kW of installed capacity than most of the country.
- System size (10kW typical): The right size depends on your electricity bill. A $150/month bill typically requires a 6–8kW system to offset 80–100%. Use our System Size Calculator to find your exact target.
- Roof type and orientation: South-facing roofs at 30° pitch are ideal. West-facing roofs produce 15–20% less but may generate more electricity during peak-price afternoon hours, improving time-of-use savings.
