[the largest photovoltaic production base in the world starts in Shaanxi] the annual 100GW single crystal silicon wafer and 50GW single crystal battery project officially started in Jinghe Xincheng, Xixian New District, Shaanxi Province on June 15. With a total investment of about 45.2 billion yuan and covering an area of 3081 mu, the project is currently the photovoltaic production base with the largest construction scale, the highest production capacity and the most advanced technology in the world, and will lead to 15000 jobs when completed. The single crystal battery with an annual output of 50GW can generate about 133 billion kilowatt-hours of electricity per year, reduce the consumption of 48 million tons of standard coal, and then reduce carbon dioxide emissions by 103 million tons, which is equivalent to an increase of 4.22 million mu of afforestation.
