憑借技術(shù)、產(chǎn)量等優(yōu)勢(shì)，過(guò)去十幾年，光伏發(fā)電的成本降幅已經(jīng)超過(guò)90%，如今在中國(guó)西部很多地區(qū)，光伏電價(jià)已經(jīng)低于火電，這為光伏可持續(xù)發(fā)展打下了良好基礎(chǔ)。根據(jù)國(guó)家發(fā)展改革委能源研究所等機(jī)構(gòu)的預(yù)測(cè)， 到2050年，中國(guó)近四成的用電量將來(lái)自光伏。

With the advantages of technology and output, the cost of photovoltaic power generation has dropped by more than 90% in the past decade. Now, in many areas of western China, the price of photovoltaic power has been lower than that of thermal power, which has laid a good foundation for the sustainable development of photovoltaic.   By 2050, nearly 40 percent of China's electricity consumption will come from photovoltaics, according to the Energy Research Institute of the National Development and Reform Commission and other institutions.

By 2050, nearly 40% of China's electricity generation will come from photovoltaics  

At the just-concluded climate summit, China made it clear that the key to green development is "green and low-carbon development of energy".  The carbon emission of photovoltaic power generation is one-tenth to one-twentieth of fossil energy power generation, which is a real low-carbon energy. However, photovoltaic power generation only accounts for 3.5% of China's electricity generation at present.  Pv will gradually become one of the important power sources in China in the future, providing a strong engine for achieving "carbon peak" and "carbon neutrality".  

One such change was detected in Dalat Banner, Inner Mongolia.  

The picture  

In the last three years, large squares have appeared in the Kubuqi Desert.  It was confirmed that these were rows and rows of photovoltaic panels.  The horse pattern alone is made up of nearly 200,000 photovoltaic panels.  At present, the whole area has more than 3 million pieces, making it the largest desert concentrated photovoltaic power generation base in China.  And the area will be expanded. Once the third phase of the project is completed, the annual power generation capacity of the whole base will reach 4 billion kilowatt hours, equivalent to the electricity demand of the whole society in an economically strong county in a year.

Thousands of miles away in Datong, Shanxi Province, former coal mining subsidence areas have also been transformed into photovoltaic bases.

In Huainan, Anhui Province, and Jiangyan, Jiangsu Province, local photovoltaic panels provide good shading for fish farming, realizing "complementary fishing light".

When looking at the whole country, the Space Institute of Chinese Academy of Sciences used satellite remote sensing images to accurately extract the distribution of photovoltaic bases for us.   Each bright spot on the map represents a concentrated photovoltaic power generation zone, and as of 2019, there were more than 2,600 such zones.  This makes the installed capacity of photovoltaic power generation in China grow rapidly.  

In 2011, China's installed capacity was only 60% of that of Japan and the United States, and 6% of that of the European Union.  Since 2013, the state has intensified energy conservation and emission reduction efforts, and the photovoltaic industry has developed rapidly.  By 2017, China had more installed capacity than the entire European Union combined.  

The picture  

The photovoltaic industrial chain is also continuously optimized and upgraded. In the four major links of photovoltaic panel production, China's output accounts for nearly 70% of the world's total, and the highest is even close to 100%.   In 2013, China overtook Japan to become the largest patent applicant country in terms of the number of original patents filed.  

With the advantages of technology and output, the cost of photovoltaic power generation has dropped by more than 90% in the past decade. Now, in many areas of western China, the price of photovoltaic power has been lower than that of thermal power, which has laid a good foundation for the sustainable development of photovoltaic.  

More than a dozen provinces in China have issued the 14th five-year energy plan, and have made it clear that they want to greatly improve the scale of photovoltaic.   Zhejiang, Jiangsu and other places to 2025 installed capacity, will increase by more than half.  By 2050, nearly 40 percent of China's electricity consumption will come from photovoltaics, according to the Energy Research Institute of the National Development and Reform Commission and other institutions.  With the continuous development of photovoltaic and other clean energy sources, China will be steadily on the road to achieving carbon peak and carbon neutrality.
