How Does Solar Energy Work ?
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. |

However, the solar system that includes the plate and the battery operated device can cost up to ten thousand dollars including installation. The solar thermal plates use the energy directly from the sun and heat the water in the tubes that carry it all over the house. So you get hot water any time you want. The special type of tubing is called solar thermal collectors. The tubing also keeps the water hot for a longer period of time.
Another method of using solar power is through photovoltaic cells. These cells are combined with the solar panels. The solar energy, when it absorbs heat from the sun, excites these cells and produces electricity. The only step that takes place using batteries is conversion of the solar energy into usable energy. In the nights, the stored solar energy is used. However, how much energy depends on how sunny the day was. It does not have to be ridiculously hot for solar panels to work. The sun has to be out and the solar energy panels are capable of generating electricity by attracting heat.
