With the progress of the manufacturing technology of solar cells and their modules, the photoelectric conversion efficiency of monocrystalline silicon cells is close to 30%, and the solar photovoltaic system is constantly upgraded, from a small independent power generation system to a large-scale solar power station system, solar power generation technology has become mature. In this field of technology, Europe, the United States, Japan and other countries in the forefront of the world, solar photovoltaic technology is more advanced, a wide range of applications, the goal of photovoltaic power generation has been to urban development, began to vigorously promote the roof of the sun grid power plan. China’s solar photovoltaic industry, due to the state’s attention to the development of new energy, has increased the investment of funds, a number of scientific research institutes in the utilization and research of solar energy has achieved fruitful results, in the development and application of solar energy products have taken a substantial step, laying a foundation for promoting the solar photovoltaic industry to the market. Although there has been great development of photovoltaic products of our country, compared with the similar products in foreign countries, its quality and technical performance are backward, it is difficult to compete with foreign products.
Domestic photovoltaic products are mainly produced in western China, and most of them are small private enterprises. Single variety, small production scale, backward means, and more stay in the workshop production, backward technology; Standards and technical specifications are not sound and do not match; Lack of necessary testing equipment, lack of process regulation supervision; Backward technical route, generally based on analog electronic circuit, product performance is unstable, poor quality; Single function affects the overall quality of the system. Therefore, it is urgent for the development of photovoltaic industry to increase capital investment, develop a variety of varieties, expand the scope of application and form large-scale production. Although Chinese photovoltaic products are relatively backward in product design and technology methods, it also has unique advantages of development, such as low product cost, direct product identification, convenient and practical, can achieve many functions by general technology means, to meet the market needs at the present stage, and the unit performance price is relatively lower than that of foreign similar products, consumers easy to accept. This is also the favorable conditions for cultivating the market at this stage.
