AJ Long Electric provides professional residential solar installation services in Alexandria, VA. Our licensed electricians have served Alexandria City for over four decades, delivering safe, code-compliant electrical work for homeowners and businesses. With deep experience across every type of residential electrical project, we bring both technical expertise and local knowledge to every job we complete in the Alexandria area. In Alexandria specifically, we most often work on pre-1960 Old Town row houses, Del Ray bungalows and Beverley Hills ranches, where weak grounding-electrode systems and 100A panels are common — a backdrop that shapes how we approach residential solar installation here.
In neighborhoods like Old Town, Del Ray, Carlyle, Eisenhower Valley, Seminary Hill, near landmarks such as King Street, Old Town Waterfront, George Washington Masonic Memorial, we have completed countless residential solar installation projects. Our familiarity with local building codes, inspection requirements, and the common electrical challenges found in Alexandria City homes ensures your project is completed correctly the first time. On the ground in Alexandria, the issue we run into most is grounding upgrades required before SPD or panel work in Old Town and Del Ray. Because the work is permitted through the Alexandria Department of Code Administration, we pull the permit, schedule the inspection, and verify grounding to NEC 250 before we close out — and Alexandria City charges its own permit fees, which we itemize up front.

Listed modules, inverters, and interconnection — not a referral to a solar-only shop.
The panel, EV circuit, battery, and array are planned together so the can is not full the day the solar shows up.
A load calculation decides whether the existing service can accept generation plus the house load.
Permit, inspection, and interconnection steps for the serving utility are confirmed before equipment is ordered.
The federal 25D 30% residential credit ended for new expenditures after December 31, 2025. We do not sell a credit we cannot deliver.
AJ Long Electric installs residential solar. The array, the interconnection, and the electrical system behind it are one project: service capacity, busbar rating, grounding, inverter or backfeed connection, and how the system will share a panel with an EV charger or a home battery. We confirm the roof and electrical conditions, write the scope, pull the electrical permit path, and coordinate utility interconnection for the address. Panel upgrades, Level 2 charging, and wall-pack batteries are quoted in the same visit when they belong in the design. Roofing or structural work outside our electrical and array scope is identified in the proposal instead of buried in a later change order. In Alexandria, we have seen how historic preservation compliance for pre-1850 structures affects homeowners. That is why we take the time to assess your entire electrical system and recommend solutions that address both immediate needs and long-term reliability. Every residential solar installation project we complete in Alexandria City includes a thorough inspection, detailed documentation, and our commitment to your complete satisfaction.

Permit fees, scope, and existing-condition surprises affect final pricing. Verify current requirements with the Alexandria Department of Code Administration and review the NFPA 70 (National Electrical Code).
Roof, service size, busbar, existing EV or battery loads, and the interconnection method are documented.
Array, electrical, panel or battery work, and any excluded roofing or structural items are itemized.
Electrical permit and interconnection requirements are confirmed for the address before equipment is ordered.
Approved array and electrical scope is installed to the listed equipment instructions.
We coordinate the electrical inspection and the utility permission-to-operate steps in the defined scope.
Yes. We install residential solar and the electrical interconnection that makes it legal: panel capacity, grounding, inverter or backfeed connection, permit path, and utility coordination for the address. Roofing or structural work outside that scope is called out in the written proposal.
Array pricing is quoted per project after a site and electrical review — roof, service size, inverter type, and whether a panel upgrade or battery is in the same job. A 200-amp panel upgrade that the array requires typically falls in the $3,500-$7,500 band and is itemized separately.
The Section 25D residential clean energy credit ended for new qualifying expenditures after December 31, 2025. AJ Long Electric does not provide tax advice. Confirm any remaining commercial or third-party-owned credit path with a qualified tax professional.
Yes. That is the point. One load calculation, one permit path, one crew that already does the panel and the charger. Solar-ready panel work is the electrical preparation inside that job when the array is staged.
No. This offer is residential. Light-commercial electrical is a separate service and does not include large commercial arrays.
Alexandria homes are mostly pre-1960 Old Town row houses, Del Ray bungalows and Beverley Hills ranches, so we frequently encounter weak grounding-electrode systems and 100A panels. The most common situation we address is grounding upgrades required before SPD or panel work in Old Town and Del Ray. Permits for this work go through the Alexandria Department of Code Administration, and Alexandria City charges its own permit fees, which we itemize up front. That local knowledge means AJ Long Electric arrives prepared for the conditions specific to Alexandria rather than treating it like any other Alexandria City job.
