Understanding Solar Panels and Their Functionality

The video tutorial explains how solar panels convert light into electricity using the photovoltaic effect. It covers the construction of solar cells, including the PN junction and electrodes, and how they are assembled into modules and systems. The tutorial also discusses energy storage with batteries and inverters, the efficiency of different solar cell types, and the physics behind the photovoltaic effect. Additionally, it touches on practical applications and considerations for solar panel installation.

What is the primary function of solar panels?
