The Electrician-Led Solar Company for Northern Virginia

Yes. AJ Long Electric designs and installs residential solar in Northern Virginia: the array, the inverter, the interconnection, and any panel, battery, or EV charger work in the same job. A master electrician is on site for every solar project.

A typical 8 to 12 kW rooftop system installs for $19,000–$34,000 cash, which is $2.40–$2.85/W. That price covers modules, racking, inverter, and interconnection labor. Fairfax County waives the residential solar permit fee, so there is no permit fee line on the proposal. A panel upgrade, when the house needs one, is itemized at the published $3,500–$7,500 range.

Yes. The bill review, the site visit, and the written proposal are free. There is no fee for the visit or the written price.

Many Northern Virginia homes on 100A or 150A service do, and some 200A panels need a main breaker or busbar change to accept the backfeed. We run the load calculation and the 120 percent busbar check during the site review. If the panel needs work, it is priced in the same proposal at the published $3,500–$7,500 range, not as a change order later.

No. That is the point. Solar companies subcontract the electrical to a contractor like us. AJ Long Electric is the electrical contractor, so the panel, the heavy-up, the interconnection, and the array are installed by one crew under one license with a master electrician on site.

Yes. The State Corporation Commission's final order on April 30, 2026 kept Dominion's one-to-one net metering credit and left SREC ownership with the customer. New net metering customers pay a $1 per month administrative fee. NOVEC runs its own net metering program, and we file the interconnection for either utility.

Your meter runs both ways. Every kilowatt-hour the array exports during the day earns a kilowatt-hour credit against what you pull at night, and the credit carries forward month to month. The utility is set by your address, not your city name, so we confirm Dominion or NOVEC from your bill and file the interconnection paperwork for you.

No. Fairfax County Land Development Services waives the permit fee for residential solar, and the county exempts the solar equipment from property tax for five years. The City of Fairfax exempts it for ten years. We pull the permit and schedule the inspection either way.

No for residential systems. Section 25D does not apply to systems installed after December 31, 2025, and our proposals do not subtract a credit you cannot claim. Rental and business-owned systems may qualify for the commercial Section 48E credit if placed in service by December 31, 2027; confirm with a CPA. AJ Long Electric does not provide tax advice. Read the IRS page or ask a tax professional.

Yes, and it is the best time to do it. The array, the battery, the EV circuit, and the panel share one load calculation and one permit, so designing them together avoids a second visit and a second panel change. Battery and EV work are itemized on the same proposal.

Not on its own. A standard grid-tied array shuts off when the grid goes down so it cannot back-feed line workers. Add a battery and transfer equipment, and the circuits you choose stay on while the array recharges the battery during the day. That is why we design the battery with the array instead of adding it later.

We quote cash and loan. The published band, $19,000–$34,000 for a typical 8 to 12 kW system, is the cash installed price. A loan proposal shows that same installed price plus the lender's terms, so you can see the dealer fee and the interest instead of a monthly payment that hides them.

A master electrician is on site for every solar project. Led by a master electrician, with our own crew on the racking and the electrical. No sales rep and no subcontractor.

No. This is a residential service for Northern Virginia homes. Light commercial electrical is a separate service.
