Texas is now the 2nd-largest solar state in the country, and for good reason: lots of sun, high electricity bills, and a deregulated energy market that makes solar savings exceptionally strong. Here is what solar actually costs in Texas in 2026 and what incentives are available.
Quick Answer: Texas Solar Costs in 2026
| System size | Before incentives | After 30% federal credit | Typical payback |
|---|---|---|---|
| 8 kW (average TX home) | ~$24,000 | ~$16,800 | 8-11 years |
| 10 kW | ~$30,000 | ~$21,000 | 8-11 years |
| 12 kW | ~$36,000 | ~$25,200 | 8-11 years |
Texas homes tend to need larger systems because AC use is so high. The average Texas home uses 1,200 to 1,500 kWh/month in summer – more than double the national average.
Texas Solar Incentives in 2026
Texas does not have a state income tax, so there is no state solar tax credit. But there are still strong incentives:
- Federal 30% tax credit – the biggest incentive available. On a $24,000 system that is $7,200 back on your federal return.
- Property tax exemption – Texas law exempts the added value of a solar system from your property tax assessment. On a $24,000 system, this can save you $500 to $600/year depending on your county rate.
- Utility rebates – Austin Energy offers rebates up to $2,500. CPS Energy in San Antonio offers rebates up to $1,800. Check with your local utility.
- Net metering – Texas does not have a statewide net metering law, but most utilities offer some form of buyback credit for excess power. Rates vary significantly by utility.
Why Texas Electricity Bills Make Solar So Attractive
Texas electricity rates have spiked significantly since Winter Storm Uri in 2021, and the deregulated market means rates can be volatile. Many Texas homeowners on variable-rate plans have seen bills of $400 to $600+ during summer months. Solar locks in your energy cost and insulates you from rate spikes.
Solar + Battery in Texas: Is It Worth It?
After Winter Storm Uri left millions without power for days, battery backup became a priority for many Texas homeowners. A Tesla Powerwall (about $10,000-$13,000 installed) gives you 13.5 kWh of backup power – enough to run essential loads for 24-48 hours. The 30% federal tax credit applies to batteries too, bringing the net cost down to roughly $7,000-$9,000.
Average Payback in Texas
Payback periods in Texas typically run 8 to 11 years – longer than California due to lower electricity rates, but still strong over a 25-year panel life. The property tax exemption adds to lifetime savings.
Finding a Good Texas Installer
Texas requires solar installers to hold a licensed electrician’s credential or work with one. When comparing quotes, check for:
- TECL (Texas Electrical Contractor License)
- NABCEP certification
- Experience with your specific utility’s interconnection process (ERCOT vs. other grids)
- Warranty of 25+ years on panels
