Smart Electrical Panel Installation
SPAN Panel and Leviton Load Center installed by the electricians who already do your panel, EV charger, battery, and solar. See every circuit from your phone, and let an EV charger and a heat pump share a 200A service.
$7,500–$9,500 for a SPAN Panel and $3,000–$5,000 for a Leviton Load Center, installed. Free quote, no commissioned sales team.

The direct answer
AJ Long Electric installs SPAN Panel and Leviton Load Center smart panels in Northern Virginia, Maryland, and DC. A smart panel is a listed load center that meters every circuit and, with smart breakers, controls them from an app, so an EV charger, a heat pump, and a battery can share the service you already have. A SPAN Panel installs for $7,500–$9,500 and a Leviton Load Center for $3,000–$5,000.
- SPAN Panel: $7,500–$9,500 installed, a full panel replacement with per-circuit control.
- Leviton Load Center: $3,000–$5,000 installed, a new load center with smart breakers on the circuits you choose.
- A smart panel manages load. It does not add capacity. When the load calculation calls for a heavy-up, it is priced in the same proposal at the published $3,500–$7,500 range.
Cost
What a smart panel costs
A SPAN Panel installs for $7,500–$9,500. A Leviton Load Center installs for $3,000–$5,000. Both are installed prices for the panel, the breakers, migrating your circuits, labeling, and the app setup. Two things keep the number down: no commissioned sales team and no subcontracted electrical.
A heavy-up, when the load calculation calls for one, is priced at the published $3,500–$7,500 range in the same proposal. EV charger, battery, and solar work are itemized too.

Why an electrician
Why hire an electrician for a smart panel
A smart panel is still a panel. Here is what that changes.
- 01 / panel
We already do the panel
A SPAN Panel is a full panel replacement and a Leviton Load Center is a new load center. Panel work is our core trade, with 30 years of Fairfax County inspections behind it.
- 02 / loads
We design the loads with the panel
The EV charger, the heat pump, the battery, and the array all land in this box. We install all of them, so the load-management rules are set for the equipment you actually have.
- 03 / capacity
We tell you when you need a heavy-up instead
Load management stretches a 200A service. It does not fix a damaged or undersized one. The load calculation decides, and a heavy-up is priced in the same proposal at the published $3,500–$7,500 range when the house needs it.
- 04 / handoff
We set up the app before we leave
Every circuit is labeled in the panel and in the app, and the load-management rules are set with you on the day of the install.
Equipment
Smart panels we design around
Listed load centers with manufacturer warranties and local support. The final platform is set in your written proposal.
- SPAN Panel
- Whole-panel replacement with per-circuit metering and control, and backup circuit selection built in for a battery.
- Leviton Load Center
- A new load center with Leviton smart breakers on the circuits you want to monitor or control.

How it works
From your panel photo to a labeled smart panel
Five steps. We handle the permit, the inspection, and the app.
- 01
Free quote from a panel photo
Send a photo of your panel and the loads you want to manage to get a preliminary recommendation and price.
- 02
Site and electrical review
A licensed electrician checks the service size, the enclosure, the breakers, equipment compatibility, and the loads you plan to add.
- 03
Written proposal
SPAN or Leviton, price, and scope in writing, with any heavy-up, EV, battery, or solar work itemized.
- 04
Permit and installation
We pull the permit, replace the panel or set the new load center, and migrate and label every circuit.
- 05
Inspection and app setup
We meet the inspector, then set the load-management rules and the app with you.
Straight answers
Frequently asked questions
What is a smart electrical panel?
A listed load center that meters every circuit and, with smart breakers, controls them from an app. A SPAN Panel replaces the whole panel. A Leviton Load Center is a new panel with Leviton smart breakers on the circuits you choose.
How much does a smart panel cost?
$7,500-$9,500 SPAN-class; $3,000-$5,000 Leviton-class, installed. The difference is a full SPAN Panel replacement versus a Leviton Load Center with smart breakers where you want them. A heavy-up, when the load calculation calls for one, is itemized at the published $3,500-$7,500 range.
Do I need a smart panel for solar or a battery?
No. A conventional panel with the right bus rating and backfeed space handles solar, and a backed-up-load panel handles a battery. A smart panel earns its place when you want circuit-level control, automatic backup circuit selection, or an EV charger sharing a tight 200A service.
Is SPAN the only option?
No. SPAN Panel is the whole-panel option. Leviton Load Center with smart breakers is the other listed path at a lower price. We recommend from your existing panel and the features you actually want.
