Solar energy We know that the main soure of energy is sunlight for humanbeing and for the world.we can use it in our daily life. We also use many types of electronics device in our life like computer,mobile,light etc.....We operate all those things by electricity which produce from generator or power station which is run by natural gas or oil,or urenium plant which is costly.If we use our sunlight instead of urenium or oil we can save our stored energy for our world. so our main consern is to save our stored energy. If we can convert our sunlight into electricity we can use the energy.So we need a such converter that can convert the light or heat energy to electric energy.In this case we can use led(lighting emmiting diode) which can convert the light into electric.then we store it into a battary. then..........................................?
