Texas Solar Panel ROI Calculator
Estimate the return on investment for solar panels in Texas
Texas Calculator
Harness the power of solar
Updated for 2025 with real Texas rates, brackets, and regulations
Texas gets excellent sun (~1,500 kWh per kW per year) but lower retail electricity rates ($0.11-0.13/kWh) than California, creating a longer solar payback period. The federal 30% Investment Tax Credit (ITC) is your primary incentive — Texas has NO state solar rebate or tax credit. However, Texas exempts 100% of solar system value from property tax assessment, and some utilities offer 1:1 net metering credits. With ERCOT's deregulated grid, solar economics vary by your electricity plan. This calculator provides an honest assessment of solar ROI in Texas, accounting for these unique factors.

Frequently Asked Questions
Is solar worth it in Texas?
Yes, but with a longer payback (8-12 years) than California (5-7 years) due to lower electricity rates and no state incentive. The 30% federal ITC is crucial. Over 25 years, Texas solar typically provides $20,000-$40,000 in net savings. Best for homeowners with high bills and south-facing roofs.
Does Texas have solar incentives?
No state-level solar rebate or tax credit. Your only incentive is the 30% federal ITC. Some utilities offer rebates: Austin Energy previously offered incentives, and some REPs offer solar buyback plans. Texas does exempt 100% of solar system value from property taxes (Tax Code §11.27).
How does net metering work in Texas?
Texas does not have a statewide net metering mandate. Each REP (Retail Electric Provider) sets its own solar buyback policy. Some offer 1:1 retail credit, others pay wholesale rates. Shop for solar-friendly REPs at powertochoose.org. Austin Energy and CPS Energy (San Antonio) have their own solar programs.
What about battery storage?
Battery storage is increasingly popular in Texas after Winter Storm Uri and summer blackouts. A 13.5kWh Tesla Powerwall costs ~$12,000-15,000 installed. Combined with solar, it provides backup power and peak shaving. Texas has no battery-specific incentive, but the federal ITC covers batteries paired with solar.
Does solar increase my property tax?
No. Texas Tax Code §11.27 specifically exempts the value of solar panels from property tax assessment. A $20,000 solar system adds $0 to your property tax bill — a significant benefit given Texas's 1.80% property tax rate (which would otherwise add $360/year for a $20K system).
