     Solar overview of solar energy is a variety of renewable energy the most important basic energy, biomass energy, wind energy, ocean energy, hydropower and so from solar, broadly speaking, more than solar contain a variety of renewable energy. Solar energy as a renewable energy refers to direct solar energy conversion and utilization. The solar radiation is converted into thermal energy use belong known as solar thermal power solar thermal technology, re-use heat to generate electricity by converting device, also fall into this technology; conversion devices, solar radiation is converted into electrical energy use belongs to solar power generation technology, photoelectric conversion devices typically use the principle of the photovoltaic effect of semiconductor devices, photovoltaic conversion, also known as solar photovoltaic technology. In the 1950s, the field of solar energy utilization of the two major technological breakthrough: First, in 1954 the United States at Bell Labs developed the 6 percent utility-type monocrystalline silicon cells, the second is the 1955 Israel Tabor selective absorbing surface concept and theory and the successful development of selective solar absorbing coating. These two technological breakthroughs for utilization of solar energy into the modern period of development laid the technical foundation. Since the 1970s, in view of the limited supply of conventional energy sources and environmental pressures increase in the world, many countries set off the development and utilization of solar and renewable energy boom. In 1973, the United States developed a sunlight power generation scheme of the government level, in 1980 and formally photovoltaic included in the public electricity supply planning, invested a total of more than 800 million U.S. dollars. In 1992, the U.S. government issued a new photovoltaic program to develop the ambitious development goals. Japan in the 1970s formulated the "Project Sunshine", 1993 "Project Moonlight" (energy efficiency programs), "Environment Programme", "Sunshine" merged into "New Sunshine Program". Germany and other European Union countries and some developing countries have also formulated the development plan. Since the 1990s, the United Nations convened a series of leaders to participate in the Summit discussion and development of the World Solar strategic planning, the International Solar Energy Convention, the establishment of the International Solar Energy Fund to promote the global solar and renewable energy development and utilization. Development and utilization of solar and renewable energy to become a major theme of the international community and common action, the countries to develop sustainable development strategies. Than 20 years, the utilization of solar energy technology research and development, commercial production, market development have gained rapid development, becoming one of the world fast and stable development of new industries.
