NEC Requirements for Solar in New York
All solar installations must comply with NEC Article 690 — Solar PV Systems. Key requirements:
NEC 690.8 — Circuit Sizing: PV conductors must carry at least 125% of maximum circuit current. For a 10A string, conductors must be rated for 12.5A minimum.
NEC 690.12 — Rapid Shutdown: Module-level shutdown must reduce voltage to 80V or less within 30 seconds. Critical for firefighter safety.
NEC 690.31 — Wiring Methods: USE-2 or PV Wire within the array; approved wiring methods (EMT, rigid conduit, MC cable) for building penetrations.
NEC 310.15 — Ampacity Derating: Conductors in conduit must be derated per Table 310.15(B)(3)(a). Account for seasonal temperature variations when sizing conductors. Use our Wire Size Calculator and Derating Calculator for proper sizing.
Solar Wire Sizing for New York
Panel strings to combiner box: Typically 10 AWG USE-2 or PV Wire for runs up to 100 feet. Use our Solar Wire Size Calculator to verify.
DC main run to inverter: Usually 6 AWG or 4 AWG THWN-2 in conduit. Keep DC voltage drop under 1.5% with our Voltage Drop Calculator.
AC from inverter to panel: A 7.6kW inverter on 240V draws ~32A, requiring a 40A breaker and 8 AWG copper minimum. Verify with our Breaker Size Calculator.
Environmental Impact
A 56.80 kW system in New York offsets approximately 32.8 metric tons of CO₂ per year, equivalent to planting 547 trees annually. New York grid carbon intensity: 0.55 lbs CO₂/kWh.
