Solar in Bethesda, MD goes through Montgomery County's eSolar program, with a building permit and a separate electrical permit. Financing can run through the Montgomery County Green Bank, a publicly chartered nonprofit that supports residential solar and storage. Standard Maryland SRECs traded near $40 in 2026, so systems are sized mainly for bill savings.
Permits for a Bethesda home
Bethesda homes are permitted by Montgomery County's Department of Permitting Services. Residential rooftop systems use the county's eSolar path with SolarAPP+, which pairs the building permit for the attachment with a separate electrical permit for the connection.
Townhouses four stories and taller are treated as commercial structures and use the commercial solar permit instead. We check the building type before design so the application goes in on the right path.

Financing through the county Green Bank
The Montgomery County Green Bank is a publicly chartered nonprofit that supports residential solar, geothermal and battery storage, offers Access Solar financing for income-qualified homeowners, and arranges preferred loan pricing with partner lenders.
It also finances larger local projects: the Green Bank provided about $184,000 toward a 90.64 kW rooftop system at Bethesda United Methodist Church. We can work with your financing choice and supply the system details lenders ask for.
