Solar Panel Converts Sunlight Into Electricity

Solar panels can come in all shapes and sizes but.

Solar panel converts sunlight into electricity.

Energy can be transferred from one type to another. N for negative the other with a tiny amount of boron p type. Here s how solar panels harvest light converting it into electricity. Solar panels use a curious bit of science called the photovoltaic effect to convert one form of energy into another.

Solar power is arguably the cleanest most reliable form of renewable energy available and it can be used in several forms to help power your home or business solar powered photovoltaic pv panels convert the sun s rays into electricity by exciting electrons in silicon cells using the photons of light from the sun. The job of solar panels is to essentially create the electrical current. Light photons are a form of energy. Photovoltaic solar panels absorb this energy from the sun and convert it into electricity a solar cell is made from two layers of silicon one doped with a tiny amount of added phosphorus n type.

A standard solar panel also known as a solar module consists of a layer of silicon cells a metal frame a glass casing and various wiring to allow current to flow from the silicon cells silicon atomic 14 on the periodic table is a nonmetal with conductive properties that allow it to absorb and convert sunlight into electricity. So how does this relate to solar cells. This electricity can then be used to supply renewable energy to your home or. Solar panels are also considered the life blood of a solar power system because solar panels actually capture the sun s radiation thereby initiating the entire process of converting sunlight into an electrical current.

Solar panels actually comprise many smaller units called photovoltaic cells. With solar cells energy in the atoms of the light photon is transferred to the atoms in the solar cell when the sunlight bumps into a solar panel knocking the electron in the solar cell loose and creating electricity. Andrew stapleton explains how those flat bluish surfaces convert the sun s rays to electrical power. Solar panels convert solar energy into dc electricity usually of 12v which is further utilized for the rest of the circuit.

The number of cells required and their size depend on the load rating.
