How Solar Panels Convert Sunlight

N type p type diffuse direct radiation how solar work the first step is to understand the different types of solar radiation.

How solar panels convert sunlight.

Simply put solar panels convert sunlight to electricity. Solar panel efficiency is a measurement of how much of the sun s energy a certain panel can convert into usable electricity. Traditional solar panels are made with silicon crystals. Combined these components harness radiant light from the sun convert it into electricity and transmit it into homes and businesses to power electrical devices like lights and appliances and provide heating and cooling via the electrical currents they create.

A basic cell is around 1 100th of an inch thick with a wide range of surface areas. This is done by capturing the electrical current generated when sunshine interacts with the solar cells in the panel and is transferred through the wiring and busbars to be converted into ac alternating current energy. Just like a sandwich it s the filling which is the most interesting part this is where photons from the sun are converted into usable electricity. The panel s photovoltaic cells allow particles of light also known as photons to knock electrons off of atoms which creates electricity.

Solar photovoltaic systems often called solar pv for short are made up of a number of components the biggest and most important being the solar panels solar inverters mounting platforms and cabling infrastructure. Simply put a solar panel works by allowing photons or particles of light to knock electrons free from atoms generating a flow of electricity. The filling of a solar cell consists of two. A typical life span is over 25 years and there are cells in place that have produced electricity reliably for over 40 years.

The components of a solar panel solar panels are made of dozens to hundreds of solar cells or photovoltaic cells which is what converts the sunlight to energy. Site admin jan 14 2017. This energy is radiated outwards towards everything and eventually. But at the heart of each system is a simple conversion process.

Photovoltaic is a term that describes the act of turning sunlight into energy. The sun is a giant star that emits energy all the time. A photovoltaic cell changes light into electricity. It creates an electrical current with sunlight.

Here s how solar panels harvest light converting it into electricity. Silicon is a very special material. Solar panels use a curious bit of science called the photovoltaic effect to convert one form of energy into another.
