Going Solar in Texas — Key Insights
1. Texas Solar Market Overview
Texas is the fastest-growing solar market in the US. Strong sun resources (especially in West and South Texas), rising electricity rates, and concerns about ERCOT grid reliability are driving adoption. Texas property tax law exempts the added value of solar from property taxes — a significant benefit in high-property-value areas.
2. Top Tip for Texas Solar Buyers
Texas net metering policies vary significantly by utility — Oncor, CenterPoint, and TNMP all have different export credit rates. Research your specific utility's policy before sizing your system. Many Texas homeowners add battery storage for grid independence after the 2021 winter storm.
3. System Size Guide for Texas
Average Texas home uses ~1,000–1,200 kWh/month (higher in hot climates with AC). A 6–8 kW system typically covers most usage. Always get a system sized to 90–110% of your actual annual consumption — oversizing costs more without proportional benefit under most net metering policies.
FAQs — Solar Panels in Texas
Solar panels in Texas cost $21,560 on average for a 7 kW system before the 30% ITC. After the credit, net cost is ~$15,092. Texas has excellent sun resources but no statewide net metering mandate — utility credit rates vary. Payback period: 8–11 years depending on utility and electricity usage.
Solar is financially positive for most Texas homeowners, though the calculus changed in 2026 after the federal residential ITC expired on December 31, 2025. Texas's incentives: Federal 30% ITC + Net Metering (varies by utility — check Oncor, AEP, CenterPoint) + Property tax exemption on solar value. Estimated payback without federal ITC: 8–11 years. With a 25-year panel lifespan and rising electricity rates, solar still provides positive lifetime returns in most states.
Most Texas homes need a 5–10 kW system. A 7 kW system produces approximately 11,498 kWh/year in Texas. Divide your annual kWh usage by that figure to estimate the right size. Your installer will perform a site assessment to optimize for your specific roof and usage patterns.
Solar financing options in Texas in 2026: (1) Cash purchase — best long-term ROI; no federal ITC (expired 12/31/2025) but state incentives apply; typically $100–$250/month in energy savings. (2) Solar loan — own the system; pay from energy savings; rates 5–10% APR via GreenSky, Mosaic, or your installer. (3) Solar lease/PPA — $0 down; the solar company may still qualify for a commercial tax credit through 2027 and passes savings to you via rates below your utility bill — more competitive now that the homeowner cash ITC is gone. (4) HELOC — often lowest interest rate (6–8% APR). Avoid loans with "dealer fees" above 2% — these inflate the effective loan amount.
The ITC expiry changed the comparison. Previously, buying solar gave you a $6,468 federal credit (30% of cost) that leasing didn't — making buying clearly superior. In 2026, that credit is gone for new purchases, but solar companies (lease/PPA providers) can still claim a commercial credit through 2027 and may pass savings to you via lower lease rates. If your state has strong incentives (Texas's state credit further benefits purchase), buying/financing still typically produces better 25-year returns. Leasing makes sense for zero upfront cost with still-lower-than-utility rates.
