Where are solar cookers used?
Solar cookers are used in areas as diverse as Chad, Israel, India, and Peru. Solar Architecture. Throughout the course of a day, solar energy is part of the process of thermal convection, or the movement of heat from a warmer space to a cooler one. When the sun rises, it begins to warm objects and material on Earth.
When was photovoltaics invented?
Photovoltaic s is a form of active solar technology that was discovered in 1839 by 19-year-old French physicist Alexandre-Edmond Becquerel. Becquerel discovered that when he placed silver-chloride in an acidic solution and exposed it to sunlight, the platinum electrode s attached to it generated an electric current. This process of generating electricity directly from solar radiation is called the photovoltaic effect, or photovoltaics.

How does solar energy work?
When the sun’s energy in the form of protons hits the surface of a panel, they are absorbed by solar cells, which make up the module. Photons then loosen electrons from the atoms that make up these cells. The free particles are then able to move across the cells, a process that results in the production of direct current (DC) electricity. The generated power from each of the cells is usually small. That is why the many solar cells in a panel are connected in series to help sum up the produced electricity.
