Solar Panel Cost in Texas (2026)
Installed solar in Texas runs about $2.20 per watt — roughly 15% below the national average of $2.58/W. With the federal residential tax credit (25D) gone as of 2026, payback here rests on a $0.15/kWh power price and 5.3 daily peak sun hours.
Worked example: a typical $150/month home in Texas
