The production of PV modules requires 1 kWh of electricity per watt and 45 kWh of power generation over the life cycle

"China's photovoltaic industry is one that contributes to the global energy transition. At the 24th East Asia and West Pacific Power Industry Association Conference held recently, Li Zhenguo, President of LONGi Green Energy Technology Co., Ltd., said.

According to reports, the industry has made a calculation that in the production process of photovoltaic modules per watt, that is, from ore to industrial silicon, polysilicon, rods, slices, and production modules, the power consumption of the glass used is 0.4 kilowatt-hours of electricity (one watt module). In general, it can be used for 25 to 30 years of life, and the whole life cycle can generate 45 kWh of electricity.

"Although 0.4 kilowatt-hour is a small number compared to its power generation capacity, if 400GW of photovoltaic modules are produced this year, it will actually consume a lot of electricity, about 160 billion kilowatt-hours, which is equivalent to the power generation of two Three Gorges hydropower stations. I think China's photovoltaic manufacturing industry has left energy consumption in our country, and even its corresponding carbon emissions have been left in China. From this perspective, China's photovoltaic industry has contributed to the global energy transition. ”

As the most dynamic and promising region in the world, the Asia-Pacific region has the largest energy demand and the fastest growth of renewable energy in the world, with electricity demand in the Asia-Pacific region increasing by 200% in the past 20 years. However, the situation is still very serious, as the Asia-Pacific region is still overly reliant on coal for power generation, accounting for 57%, accounting for more than half of the world's carbon emissions, and the comprehensive decarbonization of the Asia-Pacific region is still a long way to go.

It is worth noting that the photovoltaic industry is particularly unique. It can be seen that the power generation of the whole life cycle of a photovoltaic module is amplified by more than 100 times compared with the electricity consumed in the production of this watt module through the amplification of sunlight. Moreover, its clean and low-carbon not only caters to the trend of sustainable development, but also supports the goal of carbon neutrality.

Different from the distribution of energy sources such as coal and oil, the sun shines on the earth and can shine to any corner of the world, so from the perspective of energy security and energy equality, sunlight is the most equal, and everyone can use it. In addition, after more than ten years of development, major breakthroughs have been made in solar energy conversion efficiency technology, and the cost of photovoltaic power generation has been reduced by about 90%, making photovoltaic the cheapest power source in most countries and regions in the world.

Li Zhenguo said that today, China's photovoltaic industry manufacturing accounts for about 80% of the world's production capacity, and photovoltaic exports support the process of energy transition in the Asia-Pacific region and even the world.
