How to read Maryland

Maryland's 2025 EIA residential average was 19.53 cents per kWh. BGE, Pepco, Potomac Edison, and Delmarva Power split the state. The solar resource is a Mid-Atlantic figure, about 4.3 peak sun hours statewide in our rounded table, not a desert number. Winters are cloudy. Summer afternoons still drive air conditioning.

Utilities

Baltimore Gas and Electric serves Baltimore and much of central Maryland. Pepco serves Montgomery County and Prince George's County, including Rockville, Bethesda, and Silver Spring. Potomac Edison, a FirstEnergy company, serves Frederick and much of western Maryland. Delmarva Power serves much of the Eastern Shore. SMECO serves southern Maryland. A suburb one county over can be a different company.

Export credits and tariffs

Maryland has required net metering for eligible customer-generators, and it has an in-state solar renewable energy credit market tied to the state renewable portfolio. In 2026 the state also set a successor path for export compensation (House Bill 1532) that is scheduled to change how new systems are credited once a cap is reached or by July 1, 2027, whichever the Public Service Commission implements. Spot credit prices move and are not a wage. A proposal must name the current rider and, if it counts credits, show that those credits are contracted rather than hoped for. This site does not promise that any house will receive them. Sources: Maryland Public Service Commission (psc.state.md.us) and the Maryland Energy Administration.

Climate and roofs

Snow is common and usually temporary on a pitched roof. Tree cover in older neighborhoods cuts more production than a tenth of a sun hour. Coastal Anne Arundel and the Shore see more wind than Frederick. Hail is occasional, not a Front Range pattern.
