Solar Energy Introduction In English

There are several components that are involved in tapping the energy from the sun.

Solar energy introduction in english.

Conversion of solar energy. The solar energy is the energy obtained by capturing heat and light from the sun. 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. It is an essential source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending.

Even in sunny parts of the world s temperate regions for instance a collector must have a surface. 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. Scientists have used solar energy to power spaceships since 1958. Solar energy influences earth s climate and weather and sustains life.

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. Every hour the sun beats down with enough power to provide global energy for an entire year. 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. Although solar energy only provides 0 15 of the world s power experts believe that sunlight has the potential to supply 5000 time as much energy as.

However people also harness the sun s energy in many other different ways. The solar inverter is one the most important components of a solar photo voltaic pv system. Let the sunshine in. Solar energy in one form or another is the source of nearly all energy on the earth.

Because the intensity of solar radiation at earth s surface is so low these collectors must be large in area. 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. Tapping solar energy has become a common activity across the globe and the technology is reaching the several ends of the world where it was unheard of a few years back. Photovoltaic cells convert light into an electric current using the photovoltaic effect.

It takes an average of eight minutes for energy to travel from the sun to the earth. Humans like all other animals and plants rely on the sun for warmth and food.
