憑借技術(shù)、產(chǎn)量等優(yōu)勢,過去十幾年,光伏發(fā)電的成本降幅已經(jīng)超過90%,如今在中國西部很多地區(qū),光伏電價已經(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)國家發(fā)展改革委能源研究所等機構(gòu)的預(yù)測, 到2050年,中國近四成的用電量將來自光伏。

到2050年,中國近四成的發(fā)電量來自光伏
在剛剛結(jié)束的領(lǐng)導(dǎo)人氣候峰會上,中國明確表示綠色發(fā)展的關(guān)鍵是“能源的綠色低碳發(fā)展”。光伏發(fā)電碳排放量是化石能源發(fā)電的十分之一到二十分之一,是真正的低碳能源,但光伏發(fā)電目前僅占我國發(fā)電量的3.5%。光伏將逐漸成為未來中國重要的電源之一,為實現(xiàn)“碳達峰”、“碳中和”提供強勁引擎。
在內(nèi)蒙古的達拉特旗,衛(wèi)星發(fā)現(xiàn)了這樣一個變化。

近三年,在庫布齊沙漠上,出現(xiàn)了大片的方格。經(jīng)過確認,這是一排排的光伏板。僅這個駿馬圖案,就是由近20萬塊光伏板組成。目前,整個區(qū)域的數(shù)量超過300萬塊,是全國最大的沙漠集中式光伏發(fā)電基地。而且面積還將擴大,即將啟動的三期項目一旦完工,整個基地的年發(fā)電量可達40億千瓦時,相當于一個經(jīng)濟強縣一年的全社會用電需求。

當放眼全國,中科院空天院利用衛(wèi)星遙感影像,為我們精準提取出了光伏基地的分布情況。地圖上的每一個亮點,就代表一個光伏集中發(fā)電區(qū),截至2019年,這樣的區(qū)域就有2600多個。這讓我國光伏發(fā)電的裝機容量迅速增長。
2011年,中國的裝機容量僅為日本、美國的六成,為歐盟的6%。從2013年起,國家加大節(jié)能減排力度,光伏產(chǎn)業(yè)快速發(fā)展。到2017年,中國的裝機容量就超過了整個歐盟的總和。

光伏的產(chǎn)業(yè)鏈條也持續(xù)優(yōu)化升級, 在光伏板生產(chǎn)的四大環(huán)節(jié)中,中國產(chǎn)量占全球的比重,最低的達到近七成,最高的甚至接近100%。從原創(chuàng)專利的申請數(shù)量來看,中國在2013年就超過日本,成為最大的專利申請國。
憑借技術(shù)、產(chǎn)量等優(yōu)勢,過去十幾年, 光伏發(fā)電的成本降幅已經(jīng)超過90%,如今在中國西部很多地區(qū),光伏電價已經(jīng)低于火電,這為光伏可持續(xù)發(fā)展打下了良好基礎(chǔ)。
我國十幾個已發(fā)布十四五能源規(guī)劃的省份,都明確要大力提升光伏規(guī)模。其中浙江、江蘇等地到2025年的裝機容量,都將增長一半以上。根據(jù)國家發(fā)展改革委能源研究所等機構(gòu)的預(yù)測, 到2050年,中國近四成的用電量將來自光伏。隨著光伏等清潔能源的持續(xù)發(fā)展,中國將在實現(xiàn)“碳達峰”和“碳中和”的路上越走越穩(wěn)。




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.  

 

The picture  

 

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.  

The picture  

 

 

 

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".  

The picture  

 

 

 

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.
