China's Level of the Tech of FPV Systems in the World

What is the level of the technology of floating PV systems in the world?

Britain was the first country to study floating photovoltaic power stations, but they have not been commercially available. In the United States, floating photovoltaic plants with a capacity of 12.5MW were not connected to the grid until 2016.

The technology of the floating photovoltaic system has been advancing in Asia and Japan. In recent years, South Korea, India, the United States, Australia, Brazil and other countries are also focusing on floating photovoltaic systems.

The reason is simple. It is because that water is cheaper than that of land. The floating photovoltaic systems on the water are better marketed. In addition, the protection of water resources is one of its advantages.

Due to its early start, Japan is the country with the largest number of actual applications of floating photovoltaic power stations in the world. However, limited by various factors, the unit capacity is always small, which is one of its major complaints.

The technology level of photovoltaic systems in our country leads the world, but floating photovoltaic systems start late. However, it develops rapidly. At present, the largest floating photovoltaic station in the world has been built in China. It is connected to the grid to generate power.

The world's largest floating photovoltaic system is located in Dezhou, Shandong Province, which is named the Dingzhuang Reservoir photovoltaic system project. Dezhou Dingzhuang Reservoir system project, with an investment of about 819 million yuan, has a total capacity of 320 MW and the first phase construction of 200 MW. Upon completion, it will become the largest single floating photovoltaic system in the world.

The data shows that the 200 MW photovoltaic system project of Dingzhuang water reservoir in Dezhou adopts the world's largest standard square array - 4 MW and 8 MW square array.

The high-density polyethylene floating box + the scaffolding floating photovoltaic system is adopted, and the converging box, single crystal silicon double glass battery module and cluster inverter are fixed on the floating body.

This kind of floating photovoltaic is suitable for deep water. It is not destructive to the water body. It is environmental. It can save the basic cost, and the construction cycle is short.

When the project is fully completed, it will generate about 221 million KWH of electricity annually, with significant economic and social benefits.

According to the statistics of Shandong Dezhou Power Grid's peak power load of 4.437 million kW in 2020, one floating photovoltaic power station can solve about 1/15 of the power problems of the Dezhou power grid under the ideal peak power generation condition, which is quite remarkable!

Internationally, Europe's largest floating photovoltaic power plant was recently connected to the grid. Located on an abandoned sand mining lake in the Netherlands, the plant has a capacity of about 27.3 megawatts. It is currently the largest floating photovoltaic power project outside China.

In Japan, the construction of floating photovoltaic power stations started earlier, but they are often affected by natural disasters such as typhoons. Recently, Japan announced the completion of the reconstruction of the largest floating photovoltaic power plant after the disaster, the Yamakura 13.7MW floating photovoltaic power plant in Japan. However, commercial operations have not resumed yet.

Other countries in Asia have also moved aggressively into floating PV, with Singapore starting construction on a 60-megawatt floating PV plant in a reservoir, which is expected to be completed in 2021.

By 2024, the cumulative installed capacity of the floating PV plants worldwide is expected to reach about 4,100 megawatts, according to the agency. Although the floating photovoltaic system accounts for only a small part of its installed capacity of it, it is believed that the reduction of related component costs, and the accumulation of design, construction and operation experience, the floating photovoltaic system will soon enter the fast lane of development with the development of the industry.

After all, as long as you have a small pond, who wouldn't want to throw a "board" into the water and generate electricity?
