Science How Solar Panel Works

To be more precise a solar panel harnesses the photons emitted from the sun.

Science how solar panel works.

Solar pv panels are comprised of many small photovoltaic cells photovoltaic meaning they can convert sunlight into electricity. Solar panels work by absorbing sunlight with photovoltaic cells generating direct current dc energy and then converting it to usable alternating current ac energy with the help of inverter technology. Simply put a solar panel works by allowing photons or particles of light to knock electrons free from atoms generating a flow of electricity. A solar panel works by harnessing light emitted by the sun.

This process of fusion releases extreme amounts of energy in the form of heat and light. Our sun is an incredibly good fusion nuclear reactors and starts by fusing hydrogen into helium. In 1839 french scientist edmond becquerel discovered that certain materials would give off sparks of electricity when struck with sunlight. The first photovoltaic pv cells made of selenium were.

Solar panels actually comprise many smaller units. Solar panels generate electrical current by exploiting a phenomenon first described more than a century ago by a french physicist. Ac energy then flows through the home s electrical panel and is distributed accordingly. Solar photovoltaic pv panels are based on a high tech but remarkably simple technology that converts sunlight directly to electricity.

These cells are made of semi conductive materials most often silicon a material that can conduct electricity while maintaining the electrical imbalance needed to create an electric field.
