All about Solar Energy

We all know very well that today's life cannot be imagined without power (Energy). As the time is passing the more and more use of energy demand is increasing. Traditionally only conventional source of energy was available to us. But they are limited, offering significant pollution, less efficient. That’s why the world felt the maximum utilization of non conventional energy resources like wind, solar, fossil energy etc. Among all solar energy is considered as best because of some facts like easy and ample availability, pollution free, economical etc. Amount of solar energy solely depends on amount of solar radiation received. This paper will deal with differences between solar energy and solar radiation, solar radiation forecasting and solar radiation estimation. The reader will also come to know about the main use of solar energy as water heating, photovoltaic panels, etc. By going through this paper one can get the idea of various solar radiation measuring instruments like Pyranometer, Pyrheliometer etc. along with all paper will give detailed idea of limitations of conventional energies, future scope and need of non-conventional energy resources with all the advantages of solar energy over all other available non-conventional energies.
