Where we install solar around Washington, DC
Washington is home base, and the rules change every time you cross a line. DC, Maryland, Virginia and New Jersey each credit solar differently, so the same system can pay back very differently a few miles apart. Here is where we work and what changes in each place.

Short answer
EvoGen Solar installs and services solar across Washington, DC, the nearby Maryland suburbs in Montgomery and Prince George's counties, Northern Virginia from Arlington and Alexandria to Fairfax County, and Camden County, NJ, around our Berlin head office. The DC office on 14th Street NW handles the District and the inner suburbs.
Washington, DC
The District, from rowhouse roofs to historic blocks
Most of our work is inside the District, where DC SRECs make solar pay faster than anywhere nearby. Rowhouse flat roofs behind parapets are the everyday job; historic districts such as Capitol Hill, Georgetown and Kalorama add a preservation review we plan for from the start. Our service office sits on 14th Street NW in 16th Street Heights, central to most of the city.
Neighborhood pages cover the differences that matter: Capitol Hill and Anacostia for historic review, Georgetown for the Old Georgetown Board, Petworth and Columbia Heights for rowhouse roofs, and Brookland for pitched roofs under trees.
The District's most owner-occupied neighborhoods get their own pages too: Chevy Chase, American University Park and Spring Valley west of Rock Creek Park; Shepherd Park, Brightwood and 16th Street Heights, home of our office, in upper Northwest; Michigan Park, Woodridge and Riggs Park in Northeast; and Hillcrest east of the river.
Maryland suburbs
Montgomery and Prince George's counties
Across the line in Montgomery County, including Bethesda and Takoma Park, and in Prince George's County, College Park and Hyattsville, Maryland's rules apply: full retail net metering open to new customers until July 1, 2027, Maryland SRECs worth far less than DC's, and county programs such as the Green Bank and Prince George's tax credit.
Northern Virginia
Arlington, Alexandria, Falls Church and Fairfax
In Arlington, Alexandria, Falls Church, Fairfax County and the City of Fairfax, Dominion is the utility for most homes, with NOVEC in western Fairfax County. Virginia kept one-to-one net metering in its April 2026 order and exempts residential systems from property and sales tax.
South Jersey
Camden County, around our head office
Our head office is in Berlin, and we install across Camden County, where New Jersey pays fixed SREC-II credits for 15 years and keeps one-to-one net metering.
Area pages
Pick your county or city
