Maryland solar estimate

Solar Panel Cost in Maryland (2026)

Installed solar in Maryland runs about $2.80 per watt — roughly 9% above the national average of $2.58/W. With the federal residential tax credit (25D) gone as of 2026, payback here rests on a $0.22/kWh power price and 4.5 daily peak sun hours.

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

A $150/month electric bill in Maryland works out to about 8,295 kWh a year. Sizing a cash-purchase system to cover 100% of that:
