This 10 AWG (approximately 5.3 mm²) UL listed solar PV cable wire is suitable for North American photovoltaic systems requiring NEC Article 690 compliant DC wiring at higher current ratings. 10 AWG is the standard specification for commercial solar string cables in the US market where module string Isc values approach or exceed 15A, and for parallel-connected module string wiring using DC optimisers or module-level power electronics (MLPE).
The red and black colour options meet NEC 690.31 DC circuit colour requirements, while the UL listing confirms compliance with the safety and performance requirements of the American market authority. The XLPE jacket provides sunlight resistance per UL 4703, direct burial rating, and the flexibility needed for routing through solar racking edge clips and conduit systems on commercial installations. Rated 1500V DC; 90°C conductor temperature in free air.

10 AWG (5.3 mm²) is recommended over 12 AWG (3.3 mm²) when string one-way length exceeds 15 m, or when module string Isc exceeds 12A. For commercial flat-roof and ground-mount installations with row spacings over 10 m, 10 AWG significantly reduces voltage drop losses — the additional cable cost is typically recovered within 3–5 years through improved energy yield.
