What is the difference between solar module and solar arrays?

Solar Module:

A solar module is also commonly known as a solar panel. It is the basic building block of a solar power system. A solar module consists of multiple solar cells connected together to generate electrical power from sunlight. The solar cells, typically made of crystalline silicon or other materials, convert sunlight into direct current (DC) electricity. The individual solar modules are then combined to form a solar array.

Solar Array:

A solar array is a collection or grouping of multiple solar modules or panels connected together. The purpose of combining multiple modules into an array is to generate a higher electrical output. Solar arrays can vary in size, ranging from small residential installations with just a few panels to large utility-scale installations with thousands of panels. The arrangement of the solar modules in an array can be on the ground, mounted on rooftops, or integrated into solar farms.

In summary:

A solar module refers to a single unit or panel that contains multiple solar cells.

A solar array refers to a collection of multiple solar modules connected together to form a larger system for generating electrical power.
