What is Solar Panel
A solar panel is a device that converts sunlight into electricity using a process called the photovoltaic (PV) effect.
How a Solar Panel Works
Solar panels are made of solar cells, usually from silicon.
-
When sunlight falls on these cells, it excites electrons.
-
This movement of electrons creates direct current (DC) electricity.
-
An inverter converts DC electricity into alternating current (AC), which is used in homes and industries.
