Science how solar panel works.

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. Researchers soon discovered that this property called the photoelectric effect could be harnessed. This process of fusion releases extreme amounts of energy in the form of heat and light. In 1839 henri becquerel noted that silver and platinum electrodes.

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. Solar photovoltaic pv panels are based on a high tech but remarkably simple technology that converts sunlight directly to electricity. Solar panels actually comprise many smaller units.

To be more precise a solar panel harnesses the photons emitted from the sun. Solar panels generate electrical current by exploiting a phenomenon first described more than a century ago by a french physicist. It s an idea that has been around for well over a century. Simply put a solar panel works by allowing photons or particles of light to knock electrons free from atoms generating a flow of 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.
