Solar Energy Information In English

Solar energy is light heat and other forms of energy given off by the sun.

Solar energy information in english.

It is an essential source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending. Because the intensity of solar radiation at earth s surface is so low these collectors must be large in area. Solar energy is the transformation of heat the energy that comes from the sun it has been used for thousands of years in many different ways by people all over the world. The oldest uses of solar energy is for heating cooking and drying today it is also used to make electricity where other power supplies are not there such as in places far away from where people live and in outer space.

Passive solar 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. Even in sunny parts of the world s temperate regions for instance a collector must have a surface. The solar energy is the energy obtained by capturing heat and light from the sun. Among the most common devices used to capture solar energy and convert it to thermal energy are flat plate collectors which are used for solar heating applications.

The demand for solar energy is more and more and at present we are producing using solar energy for a number of reasons. Photovoltaic cells convert light into an electric current using the photovoltaic effect. Solar power is the conversion of energy from sunlight into electricity either directly using photovoltaics pv indirectly using concentrated solar power or a combination concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight into a small beam. Conversion of solar energy.

As of 2011 the technology produced less than one tenth of one percent of global energy demand. Solar energy is the only free clean source of energy. Solar energy does not create pollution or waste and is ecologically suitable. Solar energy can be transformed directly indirectly into any other forms of energy.

Solar energy can be collected and used to heat buildings and to make electricity.
