Solar power is nothing but the energy from the Sun in the form of radiated sunlight, heat and light. Energy from the sun has many features like free global distribution, pollution free nature and availability in abundance. Earth continuously receives incoming solar energy (insolation) on its surface. Average atmospheric conditions (clouds, dust, and pollutants) reduce the actual amount of solar power travelling through the atmosphere by 22% due to reflection and 5% due to other absorption. The atmospheric conditions not only reduce the quantity of energy reaching the earth’s surface, but also diffuse some of the incoming light. The remaining is still a vast amount of energy that is available to be utilized and put to good work.
Sunlight is also absorbed by the oceans and land masses to a great extent. The total solar energy absorbed by Earth’s atmosphere, oceans, and land masses immense per year. This amount increases day by day as much solar power plants are being set up in many countries to further absorb such energy and store them. The sun rays travels to the earth at the speed of 2, 98,000 miles per second. In one hour more sunlight falls on the earth than what is used by the entire population in one year. Think about it. Or at least out scientists did and now they have invented a number of equipments that run on these solar power.
Solar power is the conversion of sunlight into electricity by photovoltaic, concentrating solar devices or through various experimental technologies. Solar power uses technologies that convert sunlight into electricity and even thermal or mechanical power.
Benefits derived from the use of solar power is plenty. Some of them are that there’s no Fuel usage and thereby low running costs; it is modular in nature; there’s a guaranteed long-life and reliability on solar energy. Also the equipments needed to run solar energy on are very low maintenance and cost effective in the long run too. The most major benefit is that solar energy helps give clean energy, which doesn’t pollute the environment and also avoids Green House Gas Emissions. In a way usage of Solar PV systems can drastically reduce global warming.
Solar power is basically produced by collecting sunlight and converting it into electricity. It’s as simple as it sounds. All you have to do is buy a solar panel. Solar panels are large flat panels made up of many individual solar cells. These absorb the sun rays effectively from even remote locations. Normally it’s installed on rooftops or backyards so that it receives ample direct sunlight.
And nowadays the prices of solar photo-voltaic cell panels are reducing so much that every household can afford one easily. Many policy changes are being made to make solar power generation attractive on a smaller scale. This initiative has taken the world by storm because the governments of all countries are now looking forward to having a less polluted environment. Usage of solar power is the answer to all environmental woes. This will make many homes and commercial establishments free from the need to source power from the various power utilities.
