Solar energy is generated through the use of photovoltaic (PV) cells, which convert sunlight into electricity. Here's how it works:
-
Sunlight hits the PV cells: When sunlight hits the PV cells on a solar panel, it knocks electrons loose from their atoms.
-
Electrons flow through the PV cells: The movement of these electrons generates an electric current.
-
The current is directed through wires: The electric current is directed through wires to an inverter, which converts the direct current (DC) into alternating current (AC). AC is the type of electricity that is used in homes and businesses.
-
The AC electricity is used or stored: The AC electricity can be used to power homes and businesses, or it can be stored in a battery for later use.
Solar panels are typically installed on rooftops or in fields, and are connected to the electrical grid. When the solar panels generate more electricity than is being used, the excess electricity is sent back to the grid, and the homeowner or business owner is credited for the excess energy. When there is not enough sunlight to generate electricity, homes and businesses can draw from the grid as needed.
By using solar energy, we can reduce our reliance on fossil fuels and help combat climate change. Solar energy is a clean, renewable source of electricity that can be used to power homes and businesses.
