In the recent years with the rise in energy costs as well as destructive effects of the energy sources on nature, the people feel a need for another possibility. In many developing countries natural resources such as the sun are becoming much more trendy. The history of solar technology dates back thousands of years. During the 7th Century, B.C glass and mirrors were used to concentrate the sun’s heat in order to make fire.The walls and floors of buildings were designed in ways that would conserve solar heat during the day and release it during the night to keep warm. Werner von Siemens found that the discovery can not be available in the near future but it is true that light could convert directly to electricity. Afterwards, Gerald Pearson, Daryl Chapin and Calvin Fuller discover a silicon solar cell which can provide enough electricity to run tiny electrical devices. First commercial solar cells were available in 1956. With spending 300 dollars you could get a 1-watt solar cell. As times goes on this technology expanded much more. These days the Solar energy can be seen in railroads, homes, solar products such as power banks and especially remote areas.
