Solar Energy Introduction Wikipedia

Many solar cookers currently in use are relatively inexpensive low tech devices although some are as powerful or as expensive as traditional stoves and advanced large scale solar cookers can cook for hundreds of people.

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. 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. The design of a solar vehicle is severely limited by the amount of energy input into the car. 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.

A pv module is an assembly of photo voltaic cells mounted in a framework for installation. Most solar cars have been built for the purpose of solar car races. Swhs are widely used for residential and some industrial applications. Solar energy introduction solar energy is the energy obtained by capturing heat and light from the sun.

This energy is transported to the sun s surface then released into space mainly in the form of radiant light energy. A device that stores energy is generally called an accumulator or battery energy comes in multiple forms including radiation chemical gravitational potential electrical potential electricity elevated temperature latent heat and kinetic energy storage involves converting energy from forms that are. Energy the sun is the source of energy for most of life on earth. Energy storage is the capture of energy produced at one time for use at a later time.

It is an essential source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending. A solar cooker is a device which uses the energy of direct sunlight to heat cook or pasteurize drink and other food materials. Energy from the sun is referred to as solar energy.

It derives its energy mainly from nuclear fusion in its core converting mass to energy as protons are combined to form helium. Photo voltaic cells use sunlight as a source of energy and generate direct current electricity a collection of pv modules is called a pv panel and a system of panels is an array. 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. Solar cars combine technology typically used in the aerospace bicycle alternative energy and automotive industries.

The term solar panel is used colloquially for a photo voltaic pv module.
