The sun is not only a source of light; it is also crucial for all living creatures because it gives warmth and energy vital for various biological functions. Solar energy is converted into electricity with photovoltaic solar panels lined with solar cells that receive and convert the sun's rays into energy. The photovoltaic effect was discovered by Alexandre-Edmond Becquerel who discovered the physical process of converting sunlight into electricity. Meanwhile, William Grylls Adams in 1876 found a way to generate electric currents by exposing selenium to light.
Solar energy is considered a green energy source because it can be harnessed with little or no pollution. All you need is a photovoltaic system comprised of an array of solar panels, an inverter, interconnection wiring, and a battery. Together, they store energy in batteries that can be tapped for a number of uses.

This modern movement espouses reduced and wiser consumption of natural resources.
