Solar energy is the energy offered by the sun with radiation which is distributed in the environment.
In the world, home of humankind and the third world in the solar system, it is the source of water and wind. The plant on which the animal kingdom, likewise makes use of the energy transforming it into chemical energy throughout photosynthesis. With the exception of nuclear energy, geothermal energy and tidal energy (from the motion of water produced by the tide), It is the source of all energy on Earth.
Throughout numerous processes, solar power should be transformed into another beneficial type of energy for human activity in heat into electrical energy or biomass. Hence the term “solar power” is commonly utilized to describe electrical energy or heat produced from it.
Techniques to directly record a part of this energy are available and are being improved constantly. One can distinguish 3 types of energies:.
* Solar photovoltaic: This refers to electrical energy produced by transforming a part of solar radiation with a photocell (which is an electronic component, exposed to light (photons), produces a voltage). Numerous cells are linked in a solar photovoltaic module. And then, even more modules are organized to form a solar system for specific use or a solar photovoltaic nuclear power plant, which supplies an electrical distribution network. The term “photovoltaic” refers to the physical phenomenon – the photovoltaic effect – or the related innovation.
* Solar thermal is to use heat from solar radiation. It comes in different forms: thermodynamic solar power, hot water and heating, cooling, solar cookers and dryers. Solar power is a thermodynamic method that utilizes solar energy to produce electrical energy.
* Passive Solar Power: The oldest use of solar power is to benefit the direct input of solar radiation and is called passive solar Power. For a structure that benefits from excellent sunshine, it has to consider the solar energy in the architectural design: double facades, orientation to the south and glass surfaces, to name a few. The thermal insulation plays a vital role to enhance the proportion of the readily available passive solar heating and lighting. A home or a building which will certainly have passive solar power contributing to a substantial saving energy. Batteries, fans, lamps garden pumps. Today, practically everything should operate on solar power. Because many individuals carry in their bag a GPS geared up with a solar charger and solar photovoltaic panels on some roofs.
