Electrician in Great Falls, VA
Battery Backup, Multi-EV & Span Smart Panel Specialists • Tesla & ChargePoint Certified • Master Electrician Led
Great Falls electrical work is in a category of its own. The lots are large — frequently half an acre, often more, sometimes well above that. The homes are large to match. The garages frequently hold three or more vehicles. The driveways are long enough to make sub-feeder routing a real engineering question, not a casual one. And the household electrical demands are genuinely complex: multi-EV charging, EcoFlow battery backup, geothermal or heat pump HVAC, pool electrical with bonding done correctly, exterior landscape lighting on substantial outdoor footprints, well pump circuits where municipal water does not reach, and the kind of integrated home energy ecosystem that the Span smart panel was designed to manage. Rojas Electric is one of the few contractors in Northern Virginia certified for the components that Great Falls homeowners actually buy — Tesla Wall Connectors, ChargePoint, and Span smart panels — and our master electrician personally designs and scopes the larger Great Falls projects from the first call. (For homeowners adding rooftop solar, we handle the complete electrical integration — disconnect, panel work, conduit, and connection — and coordinate directly with your solar panel installer.)

About Great Falls, VA — Semi-Rural Affluent Living on Large Lots
Great Falls is an unincorporated census-designated place in northwestern Fairfax County, with a 2020 Census population of approximately 16,000. The community sits along the Potomac River north of Tysons and McLean, anchored by the historic Great Falls Park and the village center at the intersection of Georgetown Pike and Walker Road. Great Falls is one of the most affluent communities in Fairfax County and one of the highest-income communities in the United States, with a residential character defined by larger lots, mature tree cover, an absence of dense development, and a deliberate preservation of the area's semi-rural feel despite proximity to one of the most economically active corridors in the country.
For electrical work, what makes Great Falls distinct is the combination of lot size, home size, and electrical demand. A typical Great Falls residential lot is half an acre or larger, with substantial setbacks, mature landscaping, and frequently outbuildings — detached garages, pool houses, guest cottages, ADUs, workshops, and exterior landscape lighting systems. The homes themselves run from substantial older estates dating to the 1950s and earlier (in the historic core), through the 1970s and 1980s buildout that filled in much of the community, to the steady stream of newer construction and tear-down rebuilds that produce 6,000 to 10,000+ square foot homes with electrical demand to match.
The electrical conversations in Great Falls are rarely about whether to add a single EV charger — they are about how to integrate two or three EVs alongside an EcoFlow battery backup system, geothermal HVAC, pool equipment, well pump where applicable, exterior landscape lighting, and a Span smart panel managing all of it. These are not generic suburban projects. They are whole-home electrical designs that benefit from an electrician who has done several of them and knows the integration details. Rojas Electric does not install rooftop solar panels themselves — that is your solar installer's scope — but we handle every electrical aspect of integrating a solar system into your home: the solar disconnect, panel work, conduit, connection at the panel, and Dominion Energy interconnection coordination.

What Working on a Great Falls Home Actually Requires
-
Great Falls homes lose power more often than the inner-ring suburbs — heavier tree cover, more overhead service, and longer feeder runs to homes set back from the main roads. For most Great Falls households, an EcoFlow battery backup system paired with a Span smart panel is the right backup configuration: silent operation, automatic transfer to battery within milliseconds, fuel-free, exhaust-free, and intelligent about which circuits stay on during an extended outage. The Span panel automatically sheds non-essential loads (HVAC, EV charging, electric water heater) so essential circuits — refrigerator, internet, well pump, lighting, home office, medical equipment — extend runtime from hours into days. We install these as integrated systems, not as a battery plus a panel plus crossed fingers.
-
Great Falls households are increasingly two- and three-EV households. We install single chargers, dual chargers with smart load management (both chargers share an available amperage pool rather than fighting for it), and pre-wired circuits for future expansion. As certified Tesla Wall Connector and ChargePoint installers, our installations are eligible for full manufacturer warranty support.
-
A typical Great Falls renovation list includes induction cooking, two or three EV chargers, a heat pump conversion, a finished basement with theater, a hot tub or sauna, a battery backup system, and potentially pool electrical and exterior landscape lighting. The original 200-amp service rarely supports all of that. 200-amp to 400-amp service upgrades are routine for Great Falls homes — coordinated with Dominion Energy and handled start to finish.
-
Pool electrical has specific bonding and GFCI requirements that an unfamiliar electrician will miss. Pump and heater circuits require GFCI protection. Pool lighting requires low-voltage transformer installation with proper isolation. The pool equipment perimeter requires equipotential bonding to prevent a shock hazard. We install pool electrical correctly to the current code.
-
Some Great Falls homes are on well water rather than municipal supply. Well pump circuits require dedicated wiring, often with surface-mounted disconnect at the well head. Loss of power to the well pump means loss of water service — which makes the well pump a high-priority backup circuit on any battery system we design.
-
For Great Falls homeowners adding rooftop solar, we handle every electrical aspect of the integration: solar disconnect, panel upgrades when needed, conduit runs from the array to the inverter, inverter-to-panel connection, and Dominion Energy interconnection coordination. The solar panels themselves are installed by your solar installer — we coordinate directly with them on scheduling and the integration handoff.
-
For Great Falls homeowners who want indefinite runtime through extended multi-day outages and already have or plan a standby generator, we install the electrical components — transfer switch, panel wiring, and connections — coordinated with the generator supplier or gas line contractor for the fuel side. Battery backup is our primary recommendation for the typical Great Falls outage profile, but for households that need indefinite runtime, generator electrical work is part of our scope.
Before Engaging Multiple Contractors for an Integrated System
If you are planning battery backup + multi-EV charging + Span smart panel — and possibly future solar — the electrical integration between components is where things go wrong. Hiring a battery installer, an EV charger installer, and a separate electrician for the panel work, then hoping they coordinate, is the path that produces years of "the system was supposed to work this way but doesn't." Engaging a single licensed electrical contractor who is certified across the components and designs the electrical architecture as a single system from the start is the path that actually delivers. We do this regularly for Great Falls homes. (When solar is part of the plan, we coordinate directly with your solar installer on the electrical handoff.)
Permitting in Great Falls
Great Falls is unincorporated within Fairfax County, so all electrical permits are pulled through Fairfax County. Battery backup, EV chargers, panel work, pool electrical, hot tub wiring, subpanel installations, and solar electrical integration all require Fairfax County permits. Larger Great Falls projects often involve Dominion Energy coordination for service upgrades — we handle that as well. Rojas Electric runs the full permit and utility coordination process on every applicable project.

Learn MoreWhat Makes Rojas Electric Different in Great Falls
01. We Design Integrated Electrical Systems, Not Bolt-Ons
Battery backup, multi-EV charging, and a solar panel are an integrated system, not three separate purchases. We design the electrical architecture on paper before any equipment is ordered — load calculations, panel sizing, backup circuit prioritization, EV load management strategy, and the integration handoffs with your solar installer if rooftop solar is part of the plan. The result is a system that works as advertised from day one.
02. Large-Lot Experience Is the Default
Subpanels in detached garages 150 feet from the main panel. Underground feeders sized for the run distance and the actual load. Landscape lighting circuits across half-acre lots. Pool electrical with bonding done to code. These are routine projects for us, not special cases.
03. Certified for the Equipment Great Falls Actually Buys
Tesla Wall Connector, ChargePoint, Span — three of the most common Great Falls purchases. Each certification matters for warranty support and for the integration depth available with the manufacturer's app and supporting infrastructure.
04. Master Electrician Personally Scopes Larger Projects
The owner, Diego Rojas, is a master electrician who personally walks through the larger Great Falls energy system designs — confirming load calculations, advising on system sizing, and ensuring the integration plan is correct before any contracts are signed. This is not delegated to a sales team.
