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.
