2021 global photovoltaic installation map, China ranks first

　　In 2020, global energy demand fell by 4.5%, but despite this, progress in renewable energy technology is still encouraging. Renewable energy has seen strong growth across the board, with solar energy taking the lead, with an installed capacity of 127GW in 2020, the highest annual capacity expansion in history.

　　The above infographic uses data from the International Renewable Energy Agency (IRENA) to map the solar power capacity of various countries in 2021, including solar photovoltaic (PV) and concentrated solar power capacity.

　　China is the undisputed leader in installed solar capacity, with more than 35% of global capacity. More importantly, this country shows no signs of slowing down. The scale of wind and solar projects under development in China is the largest in the world, which will increase its clean energy capacity by another 400,000 MW.

　　Following China is the United States. In the first three months of 2021, the United States installed another 50,000 MW photovoltaic project. Recently, the photovoltaic capacity of the United States exceeded 100,000 MW. In the past ten years, the average annual growth rate of solar energy in the United States was 42%, which is impressive. Policies such as solar investment tax credits provide 26% tax credits for household and commercial solar systems, driving the industry forward.

　　Australia's solar power generation is only a small part of China, but due to its relatively small population, only 26 million, it ranks among the top per capita. The amount of solar radiation on the Australian continent is the highest of all continents. Currently, more than 30% of Australian households have rooftop solar photovoltaic systems.

　　China’s goal is to achieve carbon neutrality by 2060, and China is taking steps to achieve this goal. China seems to have cracked the code of the entire solar supply chain. In 2019, Chinese companies produced 66% of the world's polysilicon, which is the cornerstone of silicon-based photovoltaic modules. In addition, more than three-quarters of solar cells and 72% of global photovoltaic modules come from China.

　　Of the 10 largest solar power plants in the world, 5 are all in China. In summary, this is not surprising. With the transition to carbon neutrality, China may continue to build more power stations.

　　Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate batteries are a perfect substitute for lead-acid batteries, and are the first choice for grid-connected peak shaving, off-grid energy storage, photovoltaic energy storage, UPS, data center and other industries.

　　Solar power generation system with lithium battery energy storage system is a very promising clean energy.
