Photovoltaic power generation in the west is still serious. Last year, the average light rejection rate reached 20%.

In the first half of last year, due to the rush to install the “6·30” policy, China’s PV installed capacity showed explosive growth, which also brought a brilliant semi-annual report to major PV companies. On February 5 this year, the 2016 National Photovoltaic Power Statistics released by the National Energy Administration showed that by the end of 2016, the newly installed capacity of China's photovoltaic power generation was 34.54GW, and the cumulative installed capacity was 77.42GW. The newly added and cumulative installed capacity were the first in the world. .

It is worth mentioning that distributed photovoltaics increased rapidly last year. The data shows that the installed capacity of the new year last year was 4.24GW, which was 200% higher than the 1.39GW added in 2015.

However, the "Daily Economic News" reporter noted that although the installed capacity has grown rapidly, due to the western power limit, the problem of abandoned light in 2016 is still a difficult problem in the development of photovoltaic power plants.

Last year installed capacity exceeded 34GW

With the support of national policies for the photovoltaic industry, photovoltaic power plants are also developing rapidly in China. On February 5, the 2016 National Photovoltaic Power Statistics released by the National Energy Administration showed that by the end of 2016, the newly installed capacity of China's photovoltaic power generation was 34.54GW, and the cumulative installed capacity was 77.42GW. The newly added and cumulative installed capacity were the first in the world.

In fact, at the end of 2015, China's cumulative installed capacity of photovoltaic power generation reached 43.18 GW, which is therefore more than Germany, becoming the country with the largest installed capacity of photovoltaic power generation in the world.

It is worth noting that since 2013, the newly installed capacity of photovoltaic power generation in China has exceeded 10 GW for four consecutive years, ranking first in the world.

In this regard, photovoltaic industry expert Zhao Yuwen told the reporter of "Daily Economic News" that "last year's '6·30' policy stimulated the rush of photovoltaic enterprises, which once triggered the climax of the installed capacity of photovoltaic power stations, so it appeared last year. The installed capacity exceeds 34GW, which is inseparable from the stimulus of the '6·30' policy."

It is worth noting that distributed PV has grown at a faster rate last year. According to statistics, the newly installed capacity of the whole year was 4.24GW, which was 200% higher than the 1.39GW newly added in 2015, and the cumulative installed capacity of distributed PV was 10.32GW.

It should be noted that in 2016, provinces including Zhejiang and Jiangsu increased their subsidies for distributed PV, which also increased the installed capacity of distributed PV in these provinces.

Statistics from the National Energy Administration show that the top five provinces in distributed PV installations are Zhejiang (0.86GW), Shandong (0.75GW), Jiangsu (0.53GW), Anhui (0.46GW) and Jiangxi (0.31GW).

In response to the rapid growth of distributed PV, Liao Wei, a vice president of a photovoltaic company in Jiangsu, told the reporter of “Daily Economic News” that “distributed photovoltaics have been eye-catching in the past year, which is due to the favorable policies of the national government for distributed photovoltaics, especially the provinces. The increase in subsidies in the city has greatly promoted the role of photovoltaics. In the second half of the year, PV companies began to compete for rooftop PV resources across the country. Distributed PV has grown at a faster rate last year. We expect distributed PV in 2017. Continue to accelerate in the year and enter the golden period of rapid development."

This is also true. According to the latest “Eleventh Five-Year Plan for Power Development” (2016~2020) issued by the National Energy Administration and the National Development and Reform Commission, in 2020, the scale of solar power generation will reach 110GW or more, including distributed photovoltaic 60GW and photovoltaic power plants. 45GW, 5GW of solar thermal power generation, photovoltaic power generation strives to achieve user side parity online. According to the calculation of Lianxun Securities, the compound growth rate of distributed PV during the “13th Five-Year Plan” period will be as high as 58.17%.

The problem of abandoned light is still serious

Due to the large amount of land resources and abundant sunshine resources in the western region, it is particularly suitable for the construction of photovoltaic power stations. However, a problem that cannot be ignored is that the industrial base in the western region is poor, the digestive capacity is limited, and due to the problem of grid connection, it is caused. The electricity is difficult to transport out, so the phenomenon of photovoltaic power generation in the west is particularly serious. This phenomenon has not changed in 2016.

According to the statistics of the National Energy Administration, in the first half of 2016, the problem of light abandonment in the northwestern region was severe, and the amount of discarded photovoltaics reached 3.28 billion kWh, and the light rejection rate was 19.7%. Among them, Xinjiang and Gansu photovoltaic power generation operations are more difficult, and the light rejection rates are 32.4% and 32.1% respectively. In the first quarter of last year, Xinjiang’s light rejection rate even reached 52%. Throughout 2016, the average light rejection rate in the western region reached 20%.

In fact, in order to solve the problem of abandoned light in the west, in 2016, the scale of photovoltaic power generation has already shifted to the central and eastern regions. In the new PV installations last year, the Northwest region was 9.74 GW, accounting for only 28% of the country; the Northwest region was 24.8 GW, accounting for 72% of the country. Among them, there are 9 provinces with more than 1 million kilowatts of installed capacity in the central and eastern regions, namely Shandong (3.22GW), Henan (2.44GW), Anhui (2.25GW), Hebei (2.03GW), and Jiangxi (1.85GW). Shanxi 1.83GW, Zhejiang 1.75GW, Hubei (1.38GW), Jiangsu (1.23GW).

In this regard, Zhao Yuwen told the reporter of "Daily Economic News" that "the transfer to the central and eastern regions will reduce the rate of light loss to a certain extent, but it will not solve the problem fundamentally. The future western region is still the important development of China's photovoltaic power plants. In the region, solving the grid-connected problem of photovoltaic power generation and letting the power generated by the western photovoltaic power station be transported out is a problem that local governments and photovoltaic enterprises need to solve. Otherwise, the problem of abandoned light is still a problem that plagues the development of photovoltaic power plants."
