In addition to large-scale grid-connected power generation and off-grid applications, solar energy can also be stored by pumping, superconducting, batteries, hydrogen generation and other means. Solar energy + storage can almost meet China's future stable energy needs.Solar energy is the cleanest, safest and reliable energy in the future. Developed countries are taking the development and utilization of solar energy as the main content of energy revolution for long-term planning. Photovoltaic industry is increasingly becoming another explosive industry following the IT and microelectronics industries in the world.The best way to utilize solar energy is photovoltaic conversion, which uses the photovoltaic effect to generate direct electricity from the sun's light shining onto silicon materials.The photovoltaic industry chain formed by the application and development of silicon materials is called the photovoltaic industry, which includes the production of high-purity polysilicon raw materials, solar cells, solar cell components and related production equipment.The Ministry of Industry and Information Technology released data on August 19, 2015 that the photovoltaic industry in China increased by 30% year on year in the first half of the year.At the same time, product prices have steadily risen, business operations have generally improved, the top 4 domestic polysilicon enterprises have achieved full production, the average gross margin of the top 10 component enterprises exceeds 15%, and the average net profit margin of the 29 component enterprises on the announcement list of standards for photovoltaic manufacturing industry has increased by 6.5% year on year.
