Today in Pakistan we are facing shortage of almost every basic need of life like water, gas, and especially electricity. It is the worst conditions we are facing now a days. Since summer season is longer than winter in Pakistan. So it means we can get more and more sunlight. Solar Energy Systems will be more successful in Pakistan than any European country because thankfully we can have more sunlight than Europe. Many scientists and engineers from all over the world are working in this field.  We've used the Sun for drying clothes and food for thousands of years, but only recently have we been able to use it for generating power. The Sun is 150 million Kilometres away, and amazingly powerful. Just the tiny fraction of the Sun's energy that hits the Earth (around a hundredth of a millionth of a percent) is enough to meet all our power needs many times over. In fact, every minute, enough energy arrives at the Earth to meet our demands for a whole year - if only we could harness it properly and preserve it.
