Humans in the past had tried to make a use of solar energy. They learned how to collect solar energy during the daylight and use it when it was dark. They found some methods to use it by using glass and mirrors to concentrate and experiment to make fire. In the year 1950, there was an improvement of developing technology to find a way to convert sunlight and make it in a form of electricity by means of the process of PV cells or it is called now solar cell. Around 1958, PV cells were first used on the space satellite called Vanguard which was lifted up. After that time, there are useful uses of solar energy not only to produce for the spaces but also common uses like homes, headquarters and other places and small materials such as hand watches, calculators and etc. In the present, there are four commonly known types of solar technology discovered. The first one is passive solar. This type does not need to use the process of mechanical and electrical materials.
