For PV equipment located in environments conducive to moisture, what additional safety concern must be taken into account?

In environments where solar photovoltaic (PV) equipment is exposed to moisture, corrosion resistance is a crucial consideration. Moisture can lead to the deterioration of various components, including wiring, connectors, and metal structures, which can weaken the integrity and performance of the system over time. Corrosion can create issues such as electrical failures, reduced efficiency, and ultimately, the failure of the PV system.

By ensuring that components are suitable for environments prone to moisture—such as being treated with coatings or made from corrosion-resistant materials—the likelihood of corrosion-related problems can be significantly reduced. This is critical for maintaining the longevity and reliability of the PV installation, thus ensuring it operates effectively in the long term.

While grounding requirements, flame retardancy, and electromagnetic interference are all important safety aspects in general electrical installations, they do not specifically address the direct effects of moisture on the integrity and functionality of PV equipment as corrosion resistance does. Therefore, focusing on corrosion resistance is key to ensuring that the system can withstand environmental challenges posed by moisture.
