A PV system is relatively simple in concept, but after the NEC requirements are added for safety, the execution of the system requires considerable attention to detail. There are also significant numbers of electrical inspectors that are new to the field of inspecting PV systems.
Like the ever-changing sustainable energy industry, our wiring methods are also evolving. The increase in outdoor installations opens new opportunities for more innovative products to help solve today’s new challenges.
Before we get into the details of conductors, currents, and circuit protection on the AC side of the PV system, let’s step back and try to get a bigger picture of where are some of the dangers or hazards that need to be considered.
Working with electrical systems has inherent risks, and working with Renewal Energy (RE) systems is no exception. This article offers a look into the installer’s world of required electrical safety guidelines and procedures.
