According to data released by the National Energy Administration on the 7th, in the first half of this year, the newly added distributed photovoltaic power generation capacity of the country was 990,000 kilowatts, which exceeded the new grid-connected capacity of distributed photovoltaics in 2013. According to the analysis, under the policy “warm wind”, China's distributed photovoltaic power generation will usher in the development of “spring”.
The western part of China has good lighting conditions and does not use vast land. It is suitable for the development of centralized large-scale photovoltaic power plants, but its demand for power subsidies is high, and the local electricity demand is small, and it is difficult to absorb locally. In the eastern and central regions with large demand for electricity, the development of distributed photovoltaic power generation is easy to consume on the spot, and the demand for electricity subsidies is low. Compared with photovoltaic power plants, the same subsidy funds can support more photovoltaic power generation projects.
In 2013, China issued a number of “Opinions on Promoting the Healthy Development of the Photovoltaic Industry”, and proposed to vigorously develop the distributed photovoltaic power generation market, giving priority to supporting the construction of large-scale distributed photovoltaic power generation systems in industrial and commercial enterprises and industrial parks with high electricity prices. Support the promotion of small distributed photovoltaic power generation systems in schools, hospitals, party and government organs, institutions, and residential community buildings.
The development potential of distributed photovoltaics in China is very large. According to estimates by the National Energy Administration, about 300 million kilowatts of photovoltaic power can be installed in buildings across the country, and 80 million kilowatts can be installed in industrial parks above the provincial level. The state has also imposed policy tilt on distributed PV. At the beginning of this year, the National Energy Administration proposed a total of 14 million kilowatts of new PV power generation records for the whole year, of which 8 million kilowatts were allocated for distributed photovoltaics.
From the data point of view, although the new grid-connected capacity of distributed photovoltaics in the first half of the year has increased significantly, the scale and expectations of 990,000 kilowatts still fall. An authoritative department official told reporters that considering the factors such as filing size management and grid-connected processes, the new grid-connected capacity in the second half of the year will be much higher than the first half.
But at the same time, the road to distributed spring power generation “spring” is not smooth. Experts analyzed that distributed photovoltaic power generation also faces the practical problems that need to be solved, such as difficult roof implementation, difficult loan financing, difficult access to the grid, and difficulty in recovering electricity bills.
Among them, roof resources are the first “gateway” on the road of distributed PV development. At the national distributed photovoltaic power generation on-site exchange meeting held recently, Wu Shengfeng, director of the Zhejiang Provincial Energy Bureau, said that most of the existing roofs of enterprises in Zhejiang Province did not take into account the requirements of photovoltaic power generation, and there were problems with load-bearing, leak-proof and security. . At the same time, the large-scale enterprise with a roof of 100,000 square meters can save up to 700,000 yuan in electricity price through the sale of the roof. Many companies are reluctant to provide roofs without considering social responsibility and government push, measuring gains and losses. Due to the lack of coercion, it is difficult to implement the roof of photovoltaic power generation projects.
In the face of the difficult problem to be solved, the “Jiaxing Model” was launched as a typical experience at this national conference. Xiao Peisheng, Mayor of Jiaxing City, said that in order to fully develop and utilize the roof resources, Jiaxing City stipulates that enterprises and roofs with new buildings with a roof area of more than 1,000 square meters and new buildings with an annual comprehensive energy consumption of more than 3,000 tons of standard coal Industrial enterprises with an area of more than 5,000 square meters will simultaneously design and simultaneously build rooftop photovoltaic power generation according to the standard of photovoltaic building integration. At the same time, Jiaxing Photovoltaic High-tech Zone also unified storage and storage of roof resources, signed installation agreements with roof owners in advance, unified roof lease and electricity price concessions and contract energy policy management standards, and achieved overall mastery of roof resources in the park.
In addition to industrial and commercial enterprises, residential communities are also important positions for distributed photovoltaics. Zheng Muchun, director of the Jiangxi Provincial Energy Bureau, suggested that the state should formulate professional policies and technical standards for residential photovoltaic power generation as soon as possible, and should further clarify the preferential tax policies for distributed photovoltaic power generation subsidies.
Wu Xinxiong, deputy director of the National Development and Reform Commission and director of the National Energy Administration, said that the National Energy Administration will study and adjust the PV power plant and distributed PV subsidy policies to promote cost reduction and subsidy efficiency. Local governments must play a leading role. All parties should cooperate closely to promote greater development of distributed photovoltaic power generation and ensure that the grid-connected capacity of new photovoltaic power generation is more than 13 million kilowatts.
