Solar Engineering in Fairfax, VA

Fairfax is the economic center of Fairfax County — the county government seat, corporate headquarters, George Mason University nearby, and dense suburban commercial along the Dulles corridor spillover — with a deep pipeline of office, mixed-use, and institutional development.

What we engineer

Rooftop and ground-mount PV structural analysis — roof load capacity, ASCE 7 wind uplift and snow load checks, ballast and attachment design; full electrical design per NEC Article 690 — string sizing, inverter selection, disconnects, rapid shutdown per 690.12, and single-line diagrams. Battery energy storage systems (NEC 706), carport and canopy structures, and utility interconnection applications included.

Permits that actually pass

AHJs want stamped structural calculations, electrical one-lines, site plans with fire setbacks per IFC 1204/1205, and labeling schedules — we deliver the complete submittal package so your solar permit doesn't stall in corrections.

Backed by licensed PEs

All solar engineering is backed by Apex Grid Engineering: 10+ PEs licensed across 49 states, 20+ engineers, 15+ years of plan sets that pass plan check.
