The solar angle worth knowing · as of August 2026
Level 2 home and workplace charging in Ashburn, permitted and code-compliant. If you have solar, an EV is the best load-shifting tool you own: charging from your own midday production converts power that would export at credited one-for-one at retail against your own annual usage into power you avoid buying at the applicable residential retail rate, confirmed against your own bill. Cost is driven by your panel capacity and the cable route, not the charger.

Local charging reality
Charging reality in Ashburn
Charging economics in Ashburn are the simplest in our territory, because under retail net metering it makes little practical difference whether the car charges from the roof at noon or the grid at midnight. The exported kilowatt-hour and the imported one are valued the same, which removes the load-shifting argument entirely.
What matters instead is capacity, and this is where Ashburn households run into the ceiling. A charger is a substantial continuous load, and adding one is the most common reason a household here wants more array than the current standby threshold comfortably allows. That is the point at which the 15 kW AC question stops being theoretical.
Written for Ashburn specifically.
Solar + EV

A load calculation, the route from your panel, an electrical permit through Loudoun County and the inspection. We tell you up front whether your panel needs an upgrade.
Cost
What drives EV charger cost in Ashburn
The distance from your panel to where the car parks, spare panel capacity for a 40 to 60 amp circuit, and any trenching. 37% of homes here are detached, so most have a garage or driveway run.
Ashburn specifics
What to expect here
Local constraints that come up on Ashburn charger installs.
- 01
Permit and inspection required
Loudoun County treats hard-wired charging as electrical work.
- 02
Service panel capacity
A dedicated 40 to 60 amp circuit needs room. Load management sometimes avoids a full upgrade at lower cost.
- 03
Enclosure rating
Heat and driving rain still rule out under-specified outdoor enclosures, even without salt exposure.
- 04
Visibility and approval
Loudoun County has adopted a solar equipment tax exemption, and the terms are worth knowing before you apply: the amount and duration are tied to the system’s nameplate capacity in DC watts, the equipment must be certified by the county as used primarily for collecting or generating energy, and the county will not process an application until the system is operating and has passed all required permits. Under SB 504 a Virginia association may impose only reasonable restrictions on rooftop solar, unreasonable being a cost increase above 5% or a generation loss above 10%.
- 05
The route to the car
Panel beside the parking spot is the cheap case. A detached garage needing a trench is the expensive one. This drives price more than the charger does.
- 06
Workplace charging
For businesses, load sharing and who pays for the power matter more than hardware. See commercial.
- 07
What you pay to charge here
Dominion Energy Virginia bills at the applicable residential retail rate, confirmed against your own bill and credits exported solar at credited one-for-one at retail against your own annual usage (August 2026); NOVEC serves some Loudoun County addresses, so confirm the account. With exports credited at retail, when the car charges matters less for the bill than how much it adds to your annual usage.
- 08
Charging through an outage
Four genuine seasons, with summer cooling peaks aligned to peak production and lower winter output. Retail net metering smooths that across the year in a way an export-credit state cannot, which is the main reason a Loudoun system behaves better than its latitude suggests.

Ashburn EV charging FAQ
EV charger questions from Ashburn drivers
Should I charge my EV during the day or overnight in Ashburn?
If you have solar, daytime charging is usually better under current rates. Dominion Energy Virginia credits exported power at credited one-for-one at retail against your own annual usage while you buy power at the applicable residential retail rate, confirmed against your own bill, so charging from your own midday production converts low-value export into high-value self-consumption.
Do I need a permit for an EV charger in Loudoun County?
Yes, hard-wired EV charging equipment is electrical work requiring a permit and inspection in Loudoun County, and it must meet the National Electrical Code as adopted in Virginia. We pull the permit and handle the inspection.
How much solar does EV charger installation in Ashburn need to cover my car?
A typical EV uses roughly 3,000 to 4,000 kWh a year. Each kW of panels here makes about 1,221 kWh a year, so about 2 to 3 kW of extra solar covers it. Dominion Energy households paid about 14.1¢ per kWh on average in 2024.
Do I need a permit for EV charger installation in Ashburn?
A hardwired Level 2 charger needs an electrical permit through Loudoun County. We pull it and book the inspection.
Is EV charger installation in Ashburn worth it with solar?
Usually. Charging at midday uses power Dominion Energy would credit at credited one-for-one at retail against your own annual usage instead of exporting it. Dominion Energy households paid about 14.1¢ per kWh on average in 2024.
