The development of new energy is one of the strategies all over the world. Countries are scrambling to promote the application of photovoltaic power generation. Since the beginning of this century, the proportion of photovoltaic grid-connected power generation has become the new development trend of photovoltaic power generation. What’s more, grid-connected photovoltaic power generation is also the fastest growing technology in the entire renewable energy technology and has become the world's most concerned technology for the development of new energy. Solar energy will be an important way to address future human demand and reduce greenhouse gas emissions.

Before entering the 21st century, the sun energy has been widely used. In 2004, the German government has completed the goal of building 100,000 solar power roofs. The Italian government strongly supports the development of solar cell power generation, and its goal is to build 10,000 solar power roofs. The Japanese government has installed 7,000 rooftop solar power systems. In recent years, the world's solar photovoltaic technology and photovoltaic industry have developed rapidly. The world's photovoltaic industry has developed rapidly with an average annual growth rate of 31.2%. In 2017, the global photovoltaic cell output was 4 million kilowatts. In the next few years, the global photovoltaic cell output will be more than five times that of 2017. This shows that the development of the world's photovoltaic industry has great room for development.

Major countries in the world are working hard to increase the production scale and application scale of solar power generation equipment because solar cells will reduce the cost by 20% per doubling from the production of 10MWM. Establishing a large-scale MW-scale solar power station can not only reduce costs, but also solve power supply and environmental problems in the desert and island areas, and provide power for ecological management in desert areas and seawater desalination in islands to improve the ecological environment. Now the world has more than 10 MW-class solar power stations, the largest one of which has a capacity of 6.45MW.Sino east is one of the top solar companies in the world.
