In the first half, China's PV industry continues to move forward. National Energy Bureau released data show that as of the end of June, China's total installed capacity of photovoltaic reached 101.82 million kilowatts, for the first time among the "billion kilowatts" ranks. Among them, the first half of the country's new photovoltaic power generation capacity of 24.4 million kilowatts, an increase of 9%.
In the first half, China's photovoltaic industry is not only fast, but also a lot of Aspect.
Aspects of a Middle East household with distributed photovoltaic blowout development
Data show that the first half of this year, China's new distributed PV installed capacity of 7.11 million kilowatts, an increase of 2.9 times. Among them, households with distributed PV installed the most rapid growth, an increase of more than 7 times.
It is understood that the first half of China's distributed photovoltaic installed capacity is mainly concentrated in Zhejiang, Shandong, Anhui, three provinces in the first half of the new installed capacity of 1.25 million kilowatts, 1.23 million kilowatts, 1.38 million kilowatts, an increase of more than 2 times , The three provinces total distributed photovoltaic installed capacity accounted for 54.2% of the country. Which accounted for a large proportion of distributed photovoltaic use.
Industry experts, the first half of the household use of distributed photovoltaic development is fast, there are three main reasons. First, the distributed PV subsidies remain unchanged. Second, compared to industrial and commercial roof resources, family roof resources are relatively rich. In addition, relative to the commercial and commercial roof photovoltaic, household use of distributed photovoltaic has a simple installation, the advantages of small investment.
As the rapid development of distributed photovoltaic provinces in recent years, Zhejiang's development results for all to see. Data show that as of the end of June, Zhejiang Province, the cumulative distribution of photovoltaic installed capacity of 3.33 million kilowatts, ranking first in the country.
Zhejiang rapid development of distributed photovoltaic, thanks to the introduction of local governments to encourage the relevant policies. Zhejiang Province, Zhejiang Province, Zhejiang Province, Wenzhou, Huzhou, Jiaxing, Shaoxing, Jinhua, Quzhou and other six local governments have also introduced family roof PV policy, in the organization of security, technical requirements, Market management, financial subsidies and other aspects of support for family roof photovoltaic construction.
Similarly, the rapid development of distributed photovoltaic in Shandong is also inseparable from the strong support of the policy. In December last year, Shandong Province Development and Reform Commission issued the "Shandong Province energy long-term development plan" proposed the use of industrial parks, commercial areas, public buildings and other roof, the implementation of "tens of millions of roof" distributed photovoltaic power generation project.
In addition, as the central and eastern provinces, Anhui in the first half of the new distributed photovoltaic installed capacity of the country's first, the rapid development of distributed PV infrastructure is the main reason.
State Network Anhui Electric Power Company to provide data show that from January to June this year, Anhui new grid households and village-level PV Poverty-Stricken Power Station 1.247 million kilowatts, is the PVP project over the years the total capacity of 3.3 times the network, Anhui Poverty Alleviation Poverty Alleviation at the beginning of the year 4 times the plan, accounting for about 46% of the total grid capacity of the PV system.
In order to promote the development of distributed photovoltaic, the "solar energy development" thirteen five "plan" put forward, in the solar energy resources, power grid access to good conditions in rural areas and small towns, to promote residential roof photovoltaic projects, combined with new urbanization Construction, the transformation of the old town, the new rural construction, relocation and other unified planning and construction of roof photovoltaic projects. Driven by a number of favorable policies, the second half of this year, household distributed photovoltaic will also maintain a rapid growth. The industry is expected this year, new distributed photovoltaic will exceed 10 million kilowatts.
Aspect 2 North West part of the rate of discarded light down nearly 10%
State Energy Bureau released data show that the first half of the national electricity consumption of 3.7 billion kwh, abandoned light rate fell 4.5 percentage points, abandoned light mainly occurred in Xinjiang and Gansu. Among them, Xinjiang (including Corps) abandoned photovoltaic power of 1.7 billion kwh, discarded light rate of 26%, down 6 percentage points; Gansu abandoned power of 970 million kwh, abandoned light rate of 22%, down nearly 10 percentage points. Qinghai, Ningxia is down to 10% or less.
The first half of the problem of light abandoned, there are three main reasons. First, the impact of electricity supply and demand, the first half of the year rate of electricity to achieve a certain degree of growth, which is the most important reason. Second, good policy guidance, abandon the light issue into the government report, from the national level to promote problem solving. Third, the implementation of thermal power plant peaking, so that conventional energy into a spare, the original part of the space to move to the new energy.
CIC released data show that the first half of this year, the whole society electricity consumption grew 6.3%, an increase of 3.6 percentage points year on year growth, continued the second half of 2016 since the rapid growth momentum. Of which the secondary industry electricity consumption increased by 6.1%, driving the whole society electricity consumption increased by 4.4 percentage points, is the main driving force for the growth of electricity consumption.
Aspect three technical progress prompted power generation costs continue to decline
In recent years, China's photovoltaic industry, technological progress is very large. It is understood that the current Trina Solar 6-inch full-back electrode solar cell efficiency of 24.13%; black silicon technology, PERC technology to become the mainstream of the current battery technology companies; major enterprises to accelerate the layout of the N-type battery; HIT battery to accelerate the industry Automation and intelligent transformation of components. In the first half, single, polycrystalline efficient battery efficiency increased to 21% and 19% or more.
Technological progress directly promote the decline in production costs of photovoltaic products. Data show that in the first half, polysilicon production costs fell to 9 dollars / kg or less; silicon production costs fell to 6 cents / watt; component processing costs in 12 cents / watt. The past two years, the cost of photovoltaic components has dropped by nearly 25%, photovoltaic power generation is now available with the economy.
If the "second Five-Year" photovoltaic industry's most important task is to expand the scale, then the "three five" during the unilateral expansion of the scale will be placed in a secondary position, the most important is to promote technological progress, reduce electricity costs, Application.
Obviously, with the continuous progress of technology, the future cost of photovoltaic power generation will continue to decline.
In addition, according to the International Renewable Energy Agency (IRENA) predicted that by 2025, large-scale photovoltaic power plant initial investment costs will drop to 6757 ~ 7371 yuan / kW. While the roof of photovoltaic investment costs are expected to drop to 9828 ~ 12286 yuan / kW. The average cost of photovoltaic power generation will drop to 0.37 ~ 0.92 yuan / kWh.
