Can a single conductor cable be installed in a solar array?

The 2020 and 2017 editions of the NEC have some direction on the support and management of exposed cables. Article 690 of the NEC, Solar Photovoltaic Systems, allows single conductor cable USE-2 and PV Wire to be installed in exposed locations within the array [NEC 690.31(C)(1)].

What are the requirements for solar wire management?

Solar wire management must comply with National Electrical Code (NEC) requirements and industry safety standards to ensure safe installation and operation. NEC Article 690 provides comprehensive requirements for photovoltaic systems, including specific wire management provisions:

What type of cable should a solar system use?

Solar systems use two distinct cable types: ⚠️ Critical: Never use standard THWN wire for DC solar circuits. It lacks UV resistance and proper outdoor ratings required by NEC 690.31. Use only solar-rated PV wire or USE-2 cable for panel connections. 1. System Current Calculate maximum current your wire must carry:

Do solar PV systems need safe DC cable management?

As of the 2020 revision of the NEC (NEC 2020), all references to safe DC cable management in solar PV systems have been moved into section 690. Since many of the existing systems were installed under earlier versions of the NEC, it is important to understand requirements from earlier versions in order to assess existing arrays.
