With the rapid progress of science and technology, the exploitation capability of human beings on traditional energy sources such as petroleum, coal and the like is rapidly improved. Meanwhile, the demand of the human society for these energy sources is increasing, and the characteristics of environmental pollution and non-renewable energy sources of the traditional energy sources determine that people need to search new clean, green and renewable energy sources to replace the traditional energy sources, and solar energy is one of the energy sources. In order to reduce energy consumption and greenhouse gas emission and adjust energy structures, "million solar roof planning" has occurred as early as 1997, and the goal is to install solar energy systems on 100 million roofs or other possible locations of buildings by 2010, so that the solar energy application technology in the united states is greatly improved. At present, the external dependence of the petroleum in China reaches 51%, the energy shortage brings great hidden trouble to national security, and the severe fluctuation of the international petroleum price also brings great economic loss to China. Therefore, the promotion of new energy policies including solar energy is not only for realizing industrial structure adjustment, promoting economic growth mode transformation and enlarging employment, but also has very important practical significance, and more importantly, long-term social benefit, environmental benefit and economic benefit. Under the strong support of policies of various countries in the world, the rise of new energy industry has become an industrial revolution leading the world to go out of the valley economically, and the development space of related industries is extremely wide.
