Solar panels for homes and businesses are a popular source of renewable energy. But how do solar panels work?
At the most basic level, solar panels convert sunlight into electricity. They do this using photovoltaic (PV) cells, which are made of non-hazardous semiconductor materials like silicon. When sunlight hits the PV cells, it knocks electrons loose from their atoms, generating a flow of electricity. This electricity can then be used to power your home or business.
One of the key factors that determines the efficiency of a solar panel is the type of PV cell it uses. There are two main types of PV cells: monocrystalline and polycrystalline. Monocrystalline cells are made from a single, pure crystal of silicon, while polycrystalline cells are made from multiple silicon crystals. Monocrystalline cells are generally more efficient at converting sunlight into electricity, but they are also more expensive.
In addition to the PV cells, solar panels also contain a number of other components that help them function. For example, they have a metal frame that holds the PV cells in place and protects them from damage. They also have a layer of glass on top to protect the PV cells from the elements, and a backing material that helps to keep moisture out.
Solar Panel Installation
Once the solar panels have been installed on your roof or in your yard, they are connected to an inverter. The inverter converts the direct current (DC) electricity generated by the PV cells into the alternating current (AC) electricity that is used in most homes and businesses. From there, the electricity can be used to power your lights, appliances, and other electrical devices.
Any excess electricity that is generated by the solar panels can be sent back to the grid through a process called net metering. This allows you to earn credits on your energy bill, essentially getting paid for the excess electricity you generate.
In conclusion, solar panels are a valuable source of renewable energy that can help you save money on your energy bills and reduce your carbon footprint. By using PV cells to convert sunlight into electricity, solar panels are able to provide clean, reliable power to your home or business.
