What is the primary function of a PV module?

The primary function of a PV module is to turn light into electricity. Photovoltaic (PV) modules are specifically designed to convert sunlight directly into electrical energy through the photovoltaic effect. When light photons hit the surface of the solar cells within the module, they excite electrons, allowing them to flow and create direct current (DC) electricity. This process is fundamental to solar energy technology, making PV modules essential components in solar power systems.

Other options involve different functionalities unrelated to the primary purpose of a PV module. Storing electricity is typically managed by batteries or other energy storage systems, while converting AC power to DC power involves inverters, which are distinct devices used in solar energy systems. Additionally, while mounting structures are crucial for supporting PV modules, they do not serve the same function as the modules themselves, which is to generate electricity from sunlight.
