A typical solar module, or solar panel, usually consists of 60 or 72 solar cells. The number of cells within a solar module is crucial because it directly determines the module's power output and efficiency.

Modules with 60 cells are commonly found in residential applications, while those with 72 cells are more prevalent in commercial setups, providing higher power outputs. Each solar cell is generally designed to output approximately 0.5 volts, and with the added number of cells, the overall voltage and efficiency of the module increase, making them effective for converting sunlight into electricity at a larger scale.

By understanding the standard configurations of solar cells in a module, one can better assess the capabilities and applications of different solar panel types in energy systems.
