Solar + EV charging
Solar and EV Charger Installation in Northern Virginia
The array and the Level 2 charger from the electricians who already do both. One panel, one load calculation, one crew, one warranty, and a charger that runs on the power your roof makes.
A 10 kW array plus a Level 2 charger runs $25,200–$32,000 installed, cash. A master electrician is on site for every solar project.

Answer first
Solar and the EV charger share one panel
An EV charger is the biggest new load most homes ever add, and a solar array is the biggest new source. AJ Long Electric designs both on the same panel and the same load calculation, so the charger circuit, the backfeed breaker, and any heavy-up are one job instead of three contractors.
- A 10 kW array at $24,000–$28,500 plus a Level 2 charger install at $1,200–$3,500 is a typical $25,200–$32,000 project.
- Long, outdoor, or detached charger runs go up to $4,500 and are priced after the site visit.
- A SPAN Panel or a load-managed charger lets the charger and a heat pump share a 200A service without a heavy-up.
Cost
What solar plus an EV charger costs in Northern Virginia
Two published bands, added together. A typical 10 kW array installs for $24,000–$28,500 at $2.40–$2.85/W, and a Level 2 charger installs for $1,200–$3,500 in a typical garage. A heavy-up, a long or detached charger run, and roof work are itemized separately.

Why an electrician
Why one crew for solar and the EV charger
Solar companies subcontract the electrical. We are the electrical. Here is what that changes for a charger.
- 01 / load
We run one load calculation for both
The charger adds 40 to 60 amps of new load and the array adds backfeed on the busbar. We run the load calculation once, with both on it, before anything is ordered.
- 02 / panel
We already do the panel and the heavy-up
Many Northern Virginia homes on 100A or 150A service need a heavy-up before a charger and an array. That is our core trade, priced in the same proposal at the published $3,500–$7,500 range.
- 03 / route
We price the charger route on the site visit
A garage charger installs for $1,200–$3,500. Long, outdoor, or detached runs go up to $4,500, and we walk the route before the number goes in writing.
- 04 / management
Smart load management when the service is tight
A SPAN Panel or a load-managed charger lets the charger and a heat pump share a 200A service. We install both, so the rule is set for the equipment you actually have.

Straight answers
Frequently asked questions
Can I add solar and an EV charger at the same time?
Yes, and it is the best time to do it. One load calculation, one panel, one permit, and one crew. The charger circuit goes in while the array is being installed.
Does solar mean my EV charger does not need a panel review?
No. The array adds backfeed and the charger adds load, and the panel has to carry both. We check the busbar, the breaker space, and the service size before either goes in, and a heavy-up is priced in the same proposal when the house needs it.
What does solar plus EV charging cost?
A typical 10 kW array at $24,000–$28,500 plus a Level 2 charger install at $1,200–$3,500 comes to $25,200–$32,000 installed. Long, outdoor, or detached charger runs go up to $4,500.
Will the charger run on solar power?
During the day, yes. The array feeds the house first, and the charger is the biggest load in it. At night the charger draws from the grid, and Dominion's one-to-one net metering credits the daytime export against it on the bill.
Who is on site for the installation?
A master electrician is on site for every solar project. The charger circuit, the panel, and the array are one electrical design and one crew.
