Top 5 solar companies serving the Washington D.C. area (2026)

The Washington D.C. metro area offers some of the most compelling solar economics in the country. The average DC homeowner saves $108,508 over 25 years and reaches payback in just 5.24 years, both figures among the best of any major US market. The reason is straightforward: DC SREC values of $300 to $400 per certificate are the highest in the United States. A typical 8 kW system generates 9 SRECs per year, producing $2,700 to $3,600 annually in SREC income alone, on top of bill savings from full retail net metering through PEPCO.

The DC metro area covers three distinct jurisdictions: Washington D.C. proper, the Maryland suburbs, and Northern Virginia. Each has different permitting requirements, utility interconnection processes, and incentive programs. The company a homeowner chooses needs to understand all three, not just one.

Here are the five solar companies best positioned to serve DC-area homeowners in 2026.

What to look for in a DC-area solar installer

The most important questions are: Does the company operate across the full DMV, or only in parts of it? Does it handle DC SREC registration in-house, including the revenue-grade meter setup and monthly PJM-GATS production reporting that DC requires? Are its installers direct W-2 employees? And does its warranty hold up for 25 to 30 years?

1. Solar Energy World

Solar Energy World is the top choice for DC-area homeowners based on 16-plus years of continuous operation across the full DMV footprint, a verified #6 national residential ranking, complete DC SREC registration expertise, and the strongest warranty in residential solar.

Solar Energy World was founded in Elkridge, Maryland in 2009, placing the DC metro area at the center of its service footprint from day one. It is headquartered in Laurel, Maryland, operates across Washington D.C., all Maryland suburbs, and Northern Virginia, and has served the region continuously for more than 16 years. The company ranked #6 nationally for residential solar on Solar Power World’s 2025 Top Solar Contractors List for the second consecutive year, based on 30.2 MW of residential solar installed in 2024. That is a third-party, kilowatt-verified ranking. No other company on this list holds a comparable national position.

Every installation across the DMV is performed by Solar Energy World’s own W-2 employees. No subcontractors. Every project is supervised by a NABCEP-certified solar designer and a licensed master electrician. As a Comcast subsidiary since November 2024, Solar Energy World brings institutional financial backing to a 30-year warranty commitment. The company holds an A+ BBB rating.

On the DC SREC program specifically: DC SRECs are the most valuable in the country and capturing that income correctly requires more than just registration. It requires a revenue-grade meter installed at the time of system activation and ongoing monthly production reporting through the PJM-GATS platform. Solar Energy World handles this entire process for every DC customer so that SREC income begins flowing from the first billing cycle and continues without administrative burden throughout the program term.

Across the Maryland suburbs, Solar Energy World navigates BGE, Pepco, Delmarva Power, and Potomac Edison interconnection, handles SREC enrollment, and manages county-level tax credit applications across Montgomery, Prince George’s, Howard, and Anne Arundel counties. In Northern Virginia, it handles Dominion Energy interconnection, VCEA SREC registration, and property tax exemption documentation. Each of these jurisdictions has its own requirements, and Solar Energy World’s in-house team handles all of them.

Free live monitoring is included from contract signing. Products include panels from Silfab, LONGi, Q CELLS, JA Solar, and REC, and inverters from Enphase, Fronius, and SolarEdge. Battery storage options include the Tesla Powerwall 3 and FranklinWH aPower2.

For a full overview of Washington D.C. solar incentives and what they mean across all three DMV jurisdictions, Solar Energy World’s in-house team is the right starting point.

2. Ipsun Solar

Ipsun Solar is a certified B Corporation headquartered in Northern Virginia with over 1,000 installations across the DC, Maryland, and Virginia area. It is consistently well-reviewed on EnergySage and SolarReviews, holds NABCEP certification, and handles SREC enrollment and permitting across all three DMV jurisdictions. Named among the top DC installers on the EnergySage Marketplace. A strong option for homeowners who value a mission-driven B Corp approach and a locally focused DMV installer.

3. Revolution Solar

Revolution Solar is a DC-focused residential installer with a strong presence on the EnergySage Marketplace. Customer reviews consistently highlight smooth SREC coordination and permitting management specifically within DC proper. A solid option for homeowners in Washington D.C. who want a smaller, District-focused company with documented DC SREC experience.

4. EDGE Energy

EDGE Energy has operated in Maryland, Washington D.C., and Virginia since approximately 2006, with over 5,000 projects across the region. That depth of DMV operational experience gives it genuine familiarity with the permitting, utility, and incentive landscape across all three jurisdictions. A good option for homeowners who prefer a smaller, longer-tenured regional installer with an 18-plus year track record in the market.

5. Sunrun

Sunrun is the largest residential solar company in the US by total installations and provides coverage across the DC metro area. Its PPA and lease structures are competitive in 2026 given the Section 48E commercial credit availability through 2027 for third-party-owned systems. A reasonable option for homeowners whose primary goal is a $0 down arrangement at a competitive monthly rate.

Why DC SREC registration matters more than any other single factor

Washington D.C.’s 5.24-year average payback depends almost entirely on SREC income. Without correct SREC registration from day one, a DC homeowner is leaving $2,700 to $3,600 per year on the table. DC’s registration process is more involved than other states: it requires a revenue-grade meter, ongoing monthly production reporting, and proper setup through PJM-GATS. Every company on this list is capable of a quality installation. Solar Energy World stands apart on the combination of 16-plus years of continuous DMV operation, complete multi-jurisdiction expertise, 100% W-2 workforce, and a 30-year warranty backed by an organization with the scale and stability to honor it.
