Earthing Conductor Selection for Utility-Scale Solar Farms

Design

The solar farm earthing system is an important component of the renewable energy infrastructure. Its purpose is twofold: to safeguard personnel and equipment during electrical faults and lightning strikes, and to optimize the performance of the solar photovoltaic (PV) array.

Solar farms cover large areas; thus, their electrical earthing systems are potentially both expensive to build and maintain. Choosing the most suitable conductor material for a solar PV farm earth grid affects performance and safety, and depends on various factors, including budget, electrical performance requirements, and site-specific conditions.
