– How do solar panels work?
Photovoltaic cells, also known as solar cells, are the basic building blocks of solar panels. Solar panels work by converting sunlight into electricity through a process called the photovoltaic effect. This means that when sunlight hits the photovoltaic cells, it causes them to release electrons, which in turn creates an electric current.
The photovoltaic cells in a solar panel are typically made of silicon or other materials that have semiconducting properties. These cells are arranged in a grid-like pattern on the surface of the panel and are connected together using thin metal wires. When sunlight hits the cells, it causes the electrons to become excited and move around, creating a voltage difference between the cells.
The voltage difference created by the photovoltaic cells is channeled through the wires and into an inverter, which converts the DC (direct current) electricity produced by the cells into AC (alternating current) electricity that can be used to power homes and businesses. The AC electricity is then sent through a meter and distributed to the electrical grid.
Solar panels are most effective when they are placed in areas with plenty of sunlight, such as rooftops or open fields. They can be mounted on a variety of surfaces, including asphalt shingles, metal roofs, and flat roofs. Because they generate electricity using only the energy from the sun, solar panels are a clean and renewable source of energy that can reduce the carbon footprint of homes and businesses.
In conclusion, solar panels work by converting sunlight into electricity through the photovoltaic effect. The photovoltaic cells in a solar panel are made of semiconducting materials and are arranged in a grid-like pattern on the surface of the panel.
