Most of Gaithersburg sits on Pepco, but a slice of upper Montgomery County runs on Potomac Edison instead, and the two utilities price power differently enough to change your payback math. We confirm which one actually serves your address before we quote anything, then design around Maryland’s § 7-306 net metering law, which credits your export at full retail value.
Montgomery County’s Department of Permitting Services runs eSolar, a SolarAPP+-integrated system that can clear an eligible residential solar permit in minutes instead of the standard five-business-day review most jurisdictions still use. NEDES files that paperwork, handles your interconnection application, and installs everything from a rooftop array to a Tesla Powerwall, without you ever having to chase down a permit office yourself.
