The Photovoltaic Effect and How it Works
The photovoltaic (PV) effect is the process by which solar panels convert sunlight into electricity. When sunlight hits the solar cells in a panel, it excites the electrons, creating an electric current. This current is captured and used as electricity.
The Structure of a Solar Panel
Solar panels are made up of several components that work together to generate power:
1. Solar Cells: The core component, usually made of silicon, where the photovoltaic effect occurs.
2. Glass: Protects the solar cells from environmental factors while allowing sunlight to pass through.
3. Frame: Provides structural support and allows for easy mounting.
4. Backsheet: Protects the underside of the panel.
5. Encapsulant: Holds the cells in place and protects them from moisture and dirt.
6. Junction Box: Houses the electrical connections and diodes.
Different Types of Solar Panels
