How Solar Panels Work
Solar panels convert sunlight into electricity through a process called the photovoltaic effect. Here’s a step-by-step explanation of how this process works:
- Sunlight Absorption: Solar panels are made up of many solar cells, typically made from silicon. When sunlight hits these cells, the energy from the light is absorbed.
- Electron Excitation: The absorbed energy excites electrons in the silicon atoms, causing them to break free from their atoms.
- Electric Current Generation: As the electrons move, they create an electric current. This current is direct current (DC) electricity.
- Inverter Conversion: The DC electricity is then sent to an inverter, which converts it into alternating current (AC) electricity, the type used in homes and businesses.
- Power Usage: The AC electricity is then distributed to your home’s electrical system, powering your appliances and devices.
- Grid Connection: If your system produces more electricity than you use, the excess can be sent back to the grid, often earning you credits or payments.
