Science How Solar Panel Works

Solar panels actually comprise many smaller units.

Science how solar panel works.

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. Our sun is an incredibly good fusion nuclear reactors and starts by fusing hydrogen into helium.

In 1839 henri becquerel noted that silver and platinum electrodes. 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. The first photovoltaic pv cells made of selenium were. It s an idea that has been around for well over a century.

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. This process of fusion releases extreme amounts of energy in the form of heat and light. Researchers soon discovered that this property called the photoelectric effect could be harnessed. Simply put a solar panel works by allowing photons or particles of light to knock electrons free from atoms generating a flow of electricity.

In 1839 french scientist edmond becquerel discovered that certain materials would give off sparks of electricity when struck with sunlight.
