  Solar energy   is   radiant light and heat from the Sun   that is harnessed using a range of ever-evolving technologies such as   solar heating ,   photovoltaics ,   solar thermal energy ,   solar architecture , molten salt power plants and   artificial photosynthesis . [1] [2] It is an essential source of  renewable energy , and its technologies are broadly characterized as either  passive solar  or  active solar  depending on how they capture and distribute solar energy or convert it into  solar power . Active solar techniques include the use of  photovoltaic systems ,  concentrated solar power , and  solar water heating  to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable  thermal mass  or light-dispersing properties, and designing spaces that  naturally circulate air . The large magnitude of solar ener...

Sun based force is the change of energy from daylight into power, either straightforwardly utilizing photovoltaics (PV), by implication utilizing concentrated sunlight based force, or a blend. Concentrated sun oriented force frameworks use focal points or reflects and sun based global positioning frameworks to center a huge territory of daylight into a little pillar. Photovoltaic cells convert light into an electric flow utilizing the photovoltaic effect.[1]  Photovoltaics were at first exclusively utilized as a wellspring of power for little and medium-sized applications, from the number cruncher fueled by a solitary sunlight based cell to far off homes controlled by an off-network housetop PV framework. Business concentrated sunlight based force plants were first evolved during the 1980s. As the expense of sun based power has fallen, the quantity of matrix associated sun oriented PV frameworks has developed into the millions and utility-scale photovoltaic force stations with many...
