Working of a 100 Watt Solar Panel
The working process of a solar panel is based on the photovoltaic effect, which converts sunlight into electricity.
Here is a simple explanation of how a 100W solar panel works:
- Sunlight hits the solar cells
Solar panels contain silicon photovoltaic cells that absorb sunlight. - Electrons start moving
When sunlight particles (photons) strike the silicon cells, they energize electrons and create an electric current. - Direct current (DC) electricity is generated
The electricity generated by the panel is in DC form. - Electricity passes through an inverter
A solar inverter converts DC electricity into AC electricity. - Power is used for appliances
AC electricity can then power household appliances such as lights, fans, or chargers.
This process allows solar panels to generate electricity without fuel, noise, or pollution.
