In 2018, after the explosion of distributed photovoltaic, it will erupt again

我国太阳能资源丰富,20世纪80年代,我国科研人员根据各地接受太阳总辐射量的多少,将全国划分为如下五类地区。

In the first, second and third categories, the annual sunshine hours are more than 2200h, and the total annual solar radiation is more than 5016MJ/m2. It is a region rich in or relatively rich in solar energy resources in China, with a large area, accounting for more than two-thirds of the total area of the country. Four or five types of areas, although the conditions of solar energy resources are poor, but there are also certain USES, some of which are possible to develop and utilize.



From the perspective of the whole country, China is a country with abundant solar energy resources, and has the advantageous conditions to develop solar energy utilization. In recent years, China's photovoltaic power industry has made rapid progress with the support of national policies, among which distributed photovoltaic power generation has skyrocketed.



Rapid development of photovoltaic power generation distributed photovoltaic explosion



In 2017, China installed 53.06GW of new photovoltaic power generation, 18.52GW more than the previous year, with a growth rate of 53.62 percent. By the end of 2017, China had installed 130.25GW of photovoltaic power generation capacity, compared with the previous target of only 105GW in the 13th five-year plan for solar energy. According to the current development trend, it is expected that China's cumulative pv power generation capacity will reach 250GW by the end of 2020.



Despite the rapid development of China's photovoltaic power generation industry in recent years, there are also problems in the photovoltaic market, such as the reduction of online electricity price, the elimination of light power supply, and the expansion of renewable energy subsidy gap, etc. These problems are also difficult to solve in the short term along with the development of ground power stations. At the same time, the ground power station mainly depends on the leader plan to pull, its own loading capacity has been relatively limited. In this series of factors, China's distributed photovoltaic power generation explosion.



According to the data of the analysis report on the market outlook and investment strategy planning of China's photovoltaic power industry from 2018 to 2023 by the forward-looking industry research institute, China's distributed pv installed capacity will increase by 19.44GW in 2017, up by 15.21GW from the previous year, up by 3.7 times, accounting for 36.64% of the total installed capacity, up by 24.39 percentage points compared with 2016, and reaching a new record high. In addition, the new distributed installed capacity in 2017 is not only 4.7 times that of 2016, 14 times that of 2015, 9.5 times that of 2014 and 24.3 times that of 2013, but also far more than the accumulated installed capacity (10.32GW) at the end of 2016. Therefore, it can be said that 2017 is the first year of China's distributed photovoltaic development.



Photovoltaic power generation subsidies to reverse slope distributed photovoltaic benefits strong



On January 1, 2017, the benchmark online electricity price of newly-built photovoltaic power stations in China's first to third resource zones was adjusted to 0.65 yuan, 0.75 yuan and 0.85 yuan per kilowatt-hour respectively, down 0.15 yuan, 0.13 yuan and 0.13 yuan from 2016. Distributed photovoltaic power generation projects maintain a electricity price of 0.42 yuan per KWH.



In December 2017, the national development and reform commission according to the photovoltaic industry technology progress and cost reduction, lower after January 1, 2018 of photovoltaic power station a feed-in tariff, benchmarking Ⅰ, Ⅱ, Ⅲ resource area benchmarking feed-in tariff adjustment respectively per kilowatt hour 0.55 yuan, 0.65 yuan and 0.75 yuan. For distributed photovoltaic power generation projects that are put into operation after January 1, 2018 and adopt the mode of "self-use and residual Internet", the total electricity measurement subsidy standard is reduced by 0.05 yuan, i.e., the subsidy standard is adjusted to 0.37 yuan per KWH.



Compared with the reduction of subsidies for concentrated power stations on the ground, the growth rate tends to decline, and the distributed photovoltaic project remains strong. The subsidy will not decline in 2017, and the decrease in 2018 is far lower than that of concentrated power stations on the ground.



Policies to stimulate the development of distributed photovoltaic will accelerate



In the 13th five-year plan for energy development, it is proposed that the installed capacity of distributed photovoltaic should reach 60GW by 2020. According to the 13th five-year plan for energy development, China's annual installed capacity of distributed photovoltaic will exceed 10GW from 2018 to 2020.



In April 2018, the state energy administration issued the "distributed generation management measures" and "distributed photovoltaic power generation project management measures", which strengthened the management of photovoltaic projects and reduced the subsidy amount. If the final approach is not changed, distributed photovoltaic will have a similar "surge" of projects like wind power in 2015 in 2018.
