Solar energy works on a very simple concept. A solar heating system comes with solar panels and they are typically installed on top of the house and sunniest spot. Solar power needs the sun's direct light to work. The plates derive energy from the sun and then store it. Here it is converted into usable form of energy by a battery operated device and then supplied to the house through the regular wiring system.
Life has become impossible without the use of batteries. They are in all major electric appliances and products that we have today. A battery works on the mechanism of electrochemical changes. This involves change of chemical energy into electrical energy.
