How much does solar panels cost in Baltimore, MD?

An 8 kW solar system in Baltimore runs about $21,000 to $29,400 before incentives, and Maryland backs it up with more than most states. Baltimore gets about 4.4 peak sun hours a day, which is modest, but BGE's rates of about $0.19 per kWh, Maryland net metering, a state solar grant, and a working SREC market make the payback math better than the sun alone would suggest. Rowhome roofs are the local complication.

What's different in Baltimore

Start with the numbers. At 4.4 peak sun hours, an 8 kW array in Baltimore makes a good deal less than the same system in Phoenix, but every kilowatt-hour offsets BGE power at about $0.19 per kWh, which is above the national average. Maryland net metering means BGE credits exports at retail, so a battery is not needed to make the economics work; it is for outages, which ice storms cause often enough that some homeowners add one anyway. Ask the installer to model production month by month, because Baltimore's hazy, humid summers cut output more than a clear-sky estimate implies.

Incentives stack here. Maryland offers a state solar grant, exempts solar equipment from sales tax, and runs an SREC market where you sell certificates for each megawatt-hour you produce, and that SREC income continues for years after the system is paid off. Amounts and eligibility change, so confirm the current grant terms with the state and ask the installer who registers the system for SRECs and what they charge. The federal credit ended after 2025, so these Maryland programs carry more of the load than they used to.

Roofs are the Baltimore problem. Rowhomes in the city have flat roofs, often with limited unshaded area, and need ballasted or tilt racks, which adds cost and trims capacity; a rowhome array is often 3 to 5 kW rather than 8. Suburban homes in Baltimore County and Howard County have more roof but also mature trees, so shade analysis matters. Baltimore City and Baltimore, Anne Arundel, and Howard counties each permit solar and interconnection goes through BGE. There is no instant-permit fast track here, so ask the installer for a realistic timeline from signing to permission to operate.
