How Do Solar Panels Convert Sunlight Into Electricity

Solar cells convert the energy of photons from the sun into electricity.

How do solar panels convert sunlight into electricity.

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. Here s how solar panels harvest light converting it into electricity. The process of converting energy from the sun into electricity is called solar energy or solar power which even our ancestors used for their benefit namely to produce fire. 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.

Solar energy is leading the green revolution. The sun is an intense powerhouse outputting in the region of 10 decillion that s a 1 followed by 34 zeroes joules of. 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. When an electric circuit is formed across the top and the bottom of the cell current will.

In 2015 around half a million solar panels were installed daily around the world. Photovoltaic simply means they convert sunlight into electricity many cells linked together make up a solar panel. Nowadays many countries put their money in research of this source of energy relating to the production of electricity which is an integral part of our everyday life. But pv systems cost a lot of.

This causes a voltage to form between the top and the bottom layers of the cell. Your solar contractor knows the details and they know which types of panels to use in a given application. Solar panels actually comprise many smaller units called photovoltaic cells. Andrew stapleton explains how those flat bluish surfaces convert the sun s rays to electrical power.

If you re considering installing a solar photovoltaic pv system on your home you don t need to know how the pv cells work. Solar panels can come in all shapes and sizes but. When the photon hits the top of the cell electrons will be attracted to the surface of the cell.
