To what industry standard must solar photovoltaic systems comply?

Solar photovoltaic (PV) systems must comply with NEC standards because the National Electrical Code (NEC) provides the specific regulations governing the installation of electrical systems, including solar PV systems. The NEC outlines safety requirements to ensure that electrical installations minimize hazards associated with fire, shock, and other electrical dangers.

Compliance with NEC standards is crucial as they address wiring methods, grounding, overcurrent protection, and the overall safe operation of the electrical components in a PV system. This ensures that installations are not only functional but also safe for users and the surrounding environment.

While the other options relate to various aspects of safety and environmental protection, they do not specifically address the electrical safety and installation requirements necessary for solar systems. For example, EPA regulations focus on environmental impacts and protection, OSHA guidelines are concerned with workplace safety, and IEEE standards provide technical guidelines that may influence the design and performance of electrical systems but do not dictate installation practices. Therefore, the NEC is the primary source for the standards relevant to solar photovoltaic systems.
