Solar, battery and EV services in Washington, DC
Thirty-three services, grouped by the job you need done. Each page explains the work, the DC permits and incentives that affect it, and what moves the price.
Answered 24/7 for Washington, DC and nearby Maryland and Virginia
Our 33 solar and storage services in Washington, DC fall into five groups: home solar, batteries and EV charging, repair and service, planning and paperwork, and commercial and multifamily. If you are not sure where to start, a site assessment covers roof, shade, panel and usage in one visit.
Home solar: rooftop, rowhouse, canopy and yard arrays
Most DC homes fall into one of two roof types. Pitched shingle and metal roofs take flush-mounted panels on rails; flat rowhouse roofs take low-tilt racks that sit behind the parapet. Where the roof is shaded or too small, a roof-deck pergola, an alley carport or a yard array can carry the panels instead.
Older systems have their own options: add panels when your use grows, or repower early-generation arrays with modern panels on the same roof area.
Whichever roof you have, DC historic districts add a review step when panels would be visible from the street, and we plan the layout with that in mind from the first sketch.

Batteries, EV chargers and the panel behind them
Storage and charging live or die on the electrical panel. Many older DC houses still run on small services, so every battery or charger job starts with a load calculation.
Sometimes the answer is a full service upgrade. Often it is a smaller fix, such as load management, a smart panel or a supply-side solar connection, that costs less and avoids waiting on utility work.
Batteries in DC are mostly bought for backup, since net metering already credits exported solar, and chargers are sized to how far you actually drive.

Repair and service for systems already on the roof
Panels rarely fail outright. What fails is a connector, an inverter, a mount flashing or the monitoring connection, and production slides before anyone notices.
These services cover systems we built and systems we did not, including arrays whose installer has closed. Roof work under panels, pigeons in the gap and dirty low-tilt arrays are all part of this group.
Most repair visits start with the monitoring data, so the crew arrives knowing which string, panel or inverter to look at first.

Planning, permits and the paperwork that pays
In the District, the paperwork decides both the timeline and the income. Permits, historic review and Pepco interconnection set when a system can run, and SREC registration decides whether it earns certificates once it does.
This group also covers the checks that come before any purchase: a site assessment, an energy audit, or an inspection when a house with solar is changing hands.
These jobs are where certificate income is won or lost, because a DC system has to be registered before it creates a single SREC.

Commercial and multifamily solar
Larger buildings bring structural review, multiple meters, tenants, boards and parking lots into the design. A canopy over a surface lot or a garage top deck can make power where the roof cannot.
Storage and EV charging for businesses are sized from interval data and parking patterns, not rules of thumb, so each project starts with a look at how the site actually runs.
Commercial work is phased so tenants, deliveries and parking keep running while the crew builds.

How we work
One crew from the roof to the paperwork
The same team that checks your roof files the permits, installs the system, deals with Pepco and registers the SRECs. That matters in DC, where a missed filing can leave a working array earning nothing.
We also stay after the install. Monitoring, cleaning, repairs and roof-work removal keep a system producing for its whole life, whoever built it.
Questions about our services
A site assessment. It tells you whether the roof, shade and electrical panel suit solar before any design or price.
Yes. Repairs, inverters, cleaning, monitoring, removal for roof work and SREC paperwork all apply to any installer's system.
Often. A maintenance visit can include cleaning, and a reroof is a good time to repower or add a battery.
Yes. A battery can charge from the grid for backup, and solar can be added later.
New systems, expansions, repowering and battery additions all change the interconnection, so each needs a Pepco filing.
Yes. Commercial roofs, carports, EV charging, storage and multifamily roofs each have their own page here.
