Alabama solar estimate

Solar Panel Cost in Alabama (2026)

Installed solar in Alabama runs about $2.45 per watt — roughly 5% 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 4.8 daily peak sun hours.

Worked example: a typical $150/month home in Alabama

A $150/month electric bill in Alabama works out to about 12,000 kWh a year. Sizing a cash-purchase system to cover 100% of that:
