Which article would you refer to for guidelines related to solar photovoltaic systems?

The correct reference for guidelines related to solar photovoltaic systems is Article 690 of the National Electrical Code (NEC). This article specifically addresses the installation requirements, equipment, and safety protocols necessary for photovoltaic systems to ensure proper performance and reduce risks associated with electrical hazards. Article 690 includes details on system components such as modules, inverters, wiring methods, and grounding, offering comprehensive guidance for installers and electricians working with solar technology.

By focusing on safety and compliance in photovoltaic installations, Article 690 supports the growing adoption of solar energy while ensuring that systems are reliable and integrate seamlessly with the electrical grid. This makes it the go-to resource for anyone involved in the design, installation, or inspection of solar photovoltaic systems.
