  Solar energy is the most promptly available source of energy. Solar energy is a thermal energy. It does not belong to anyone and is completely free. It is also one of the most important non-conventional sources of energy because it is non-polluting and helps in reducing the greenhouse effect. When we hang out our clothes to dry in the sun, there we use the energy of the sun. Similarly, solar panels absorb the energy of the sun to provide heat for heating water and for cooking. Such systems are available in the market and they are being used in factories and homes. Solar energy can also be used to meet our electricity necessities. Through in Solar Photovoltaic cells, solar radiation gets converted into DC electricity directly. This electricity can either be stored in the battery or can be used as it is. Solar Photovoltaic cells can be used for many applications such as:

a.       domestic lighting

b.       street lighting

c.       water pumping

d.       desalination of salty water

e.       powering of remote telecommunication repeater stations

This energy is used mainly for Drying/Timber seasoning, Cooking/Heating, Cooling, Distillation, Electricity/Power generation, Cold storage, Refrigeration. These are some of the gadgets and other devices that we can use as a solar device are Solar cooker, concentrating collectors, Flat plate solar cookers, Solar hot water systems, Solar pond, Solar hot air systems, solar stills, Solar Dryers, Solar photovoltaic systems, Solar timber kilns, Power Tower, Solar collectors, Solar pond, Air conditioning, coupled to absorption, Concentrating collectors,  Refrigeration systems. If the means to make efficient use of solar energy could be found, it would reduce our dependence on non-renewable sources of energy and make our environment cleaner.
