Which of the following describes the structure of a PV array?

The structure of a photovoltaic (PV) array is best described as encompassing cells, panels, and arrays. This is because a PV system consists of multiple layers and components that work together to convert sunlight into electricity.

Solar cells, which are the fundamental building blocks, are assembled into panels. These panels are then combined to form an array. An array is essentially a collection of several panels, allowing for a larger surface area to capture sunlight and generate more electricity than a single panel or cell could provide on its own.

Understanding this structure is crucial because it highlights how solar energy systems are designed to optimize efficiency and power output by scaling the number of cells and panels based on the energy needs and available space. This comprehensive view helps clarify how solar energy systems are implemented in residential, commercial, or utility-scale applications.
