Solar Energy And Its Applications

The pollution is increasing day by day, so it is our responsibility to reduce it and save the world. Every body is talking about “Go Green” and taking steps towards it. We must prefer the energy resources that reduce the pollution and are renewable. A very easy choice for it is using solar energy. Solar energy is extracted from sunlight i.e. sunlight is converted into energy. There are various ways of using solar energy. It can be in the form of Solar cells or Solar heating or Solar lighting and many more.

Solar cells (sometimes referred to as Photovoltaic cells) convert sunlight into electricity and are combinely used to as solar panels that are very efficient and effective way of using electricity. They absorb sunlight and their reaction with silicon material present in it produces electricity in the form of direct current(DC). Later on, it is converted into alternate current(AC), that is normally used for domestic purposes. In a sunny day, a solar panel of just single square meter can produce power to light a 100w bulb.

solar heating, a source of clean energy are considered as an awesome option for the heating purpose. It can either be heating up your houses or heating the water. It is helpful in many ways like reducing pollution caused from coal, oil or gas used for heating purpose earlier. This is a renewable source of energy and, one does not need to fear for its extinction. It can be used in two ways: direct system and Indirect system. Direct system work for domestic purpose to heat the home's water supply. Indirect system work by using fluid of low-freezing point to collect solar energy. These are mainly used in for industrial purpose to heat the water tank.

solar lighting is mainly used to light up the streets or your own pathway or landscape or the spotlights. These lights come in different sizes, colors, materials and types. They simply require direct sunlight. They are also capable of running with rechargeable batteries, but require to recharge during the day through sunlight. They are quite inexpensive and can be afforded easily.
