Solar panels are devices that are designed to absorb the sun's energy and convert it into electricity. They do this by using photovoltaic cells, which are made from a special type of material called silicon. When sunlight hits the cells, it knocks loose electrons from the silicon atoms, creating an electrical current. This current is then sent to an inverter, which converts it into usable electricity that can be used to power your home or business.
Here's a more detailed breakdown of how solar panels work:
Photons (particles of sunlight) strike the solar panel and are absorbed by the photovoltaic cells.
The energy from the photons is transferred to the electrons in the silicon atoms, which become excited and start moving around.
The excited electrons are captured by electrodes and conducted through wires as an electric current.
The electric current flows to an inverter, which converts it from direct current (DC) to alternating current (AC). This is the type of electricity that is used in homes and businesses.
The AC electricity is then sent to the electrical panel, where it can be used to power appliances and other devices. Any excess electricity that is generated can be sent back to the grid or stored in a battery for later use.
Overall, solar panels are a clean, renewable, and efficient way to generate electricity and reduce our reliance on fossil fuels.
