Science How Solar Panel Works

It s an idea that has been around for well over a century.

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. 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. To be more precise a solar panel harnesses the photons emitted from the sun. Ac energy then flows through the home s electrical panel and is distributed accordingly.

This process of fusion releases extreme amounts of energy in the form of heat and light. Solar panels actually comprise many smaller units. 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.

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. In 1839 french scientist edmond becquerel discovered that certain materials would give off sparks of electricity when struck with sunlight. A solar panel works by harnessing light emitted by the sun. In 1839 henri becquerel noted that silver and platinum electrodes.

Solar pv panels are comprised of many small photovoltaic cells photovoltaic meaning they can convert sunlight into electricity.
