In 2017, China's newly installed photovoltaic power generation achieved 53 million kilowatts, an increase of 53% year-on-year, and ranked first in the world for five consecutive years. Among these, it represents high-efficiency, high-reliability, high-yield single-crystal photovoltaic module installed capacity from three. Less than 5% jumped to 36% before the end of the year. China's high-end PV manufacturing is in full swing.
Going into the 'frontier' of energy consumption
In 2017, China’s newly installed capacity reached 53 million kilowatts, and its cumulative installed capacity of photovoltaics reached 130 million kilowatts. What is the picture of such a mass landing on the application side? If we have not seen the amazing array of large-scale ground-based photovoltaic power stations that stand outside the vast highway, we have not felt it. The leader project has given rise to the thriving vitality of coal-mining subsidence areas, or it can not believe that large-scale water and photovoltaic power generation projects such as mountainous land will bring stable benefits to the high land costs. As a result, distributed projects that are increasingly close to urban and rural production and living will allow You appreciate the great changes in energy use over the years.
Today, in the production and construction plants, in public institutions, schools, hospitals and other office space, beside the expressway, in residential villas... more and more roofs, idle spaces are embedded with photovoltaic power generation systems.
According to Wang Bohua, secretary general of the China Photovoltaic Industry Association, “Since 2014, China's PV industry has entered a new round of rapid growth. The new installed capacity market and total cumulative installed capacity have won the first place in the world, and have attracted worldwide attention. Outstanding performance. 'Because of the characteristics of flexibility, adaptability, and outstanding adhesion, solar photovoltaic power generation gradually breaks through the innate bottlenecks in the use of renewable energy sources, from resource-rich areas to the 'frontier' of energy consumption, and The play should be effective.
According to the data released by the National Energy Administration, China's distributed photovoltaic installed capacity reached 19.4 million kilowatts in 2017, with a cumulative installed capacity of 29.6 million kilowatts, accounting for 22.81% of the total installed capacity. Zhejiang, Shandong, and Anhui Provinces have newly installed installed photovoltaic capacity in the three countries. 45.7%.
Mr. Zhang, who lives in Ningjin County, Dezhou, Shandong Province, thinks of air conditioners at home. The refrigerator and the washing machine use electricity at no cost. There is a steady monthly gain of emotion and emotion. In August 2017, Mr. Zhang’s home installed Longji Leye’s double-sided. The 355-Watt module 10-kilowatt power station was successfully connected to the grid. 'Every day I compare the power generated by other photovoltaic power plants and generate 10 kWh of electricity per day. 'It is understood that the use of high-efficiency components with excellent power generation performance is equivalent to the power output of a conventional component in the same village. The gain is as high as 27.66%. In the densely populated and centrally eastern China, distributed photovoltaics demand higher system reliability and economy.
Li Wenxue, the co-director of the China Distributed Energy Innovation Application Alliance, stated: 'Distributed photovoltaics are showing an encouraging trend of explosive growth. Distributed development has extremely high requirements on product quality, installation, and operation and maintenance services. Efficiency, high reliability and reliable photovoltaic products are the foundation of the sustainable development of the market. 'It is understood that due to the oversupply of domestic photovoltaic manufacturing capacity in previous years, a large number of low-quality and inefficient photovoltaic products have flowed into the distributed market.
In August 2017, the aim was to resist the introduction of low-quality, low-efficiency photovoltaic products into the distributed market. The distributed 3.0 elite enterprise alliance was established. Recently, the alliance released the 3.0 core component initiative standards. The standards meet industry requirements. Under the premise, a standard initiative was carried out on the core components of the 3.0 system to provide benchmarks and lessons for the future promotion and application of photovoltaic systems in the market, and to promote efficient and high-quality products into distributed terminals.
Relying on advanced production capacity to achieve leapfrog development
Zhong Baoshen, president of the All-Union New Energy Chamber of Commerce, once predicted that: Photovoltaic power generation or parity access will be achieved by 2020. To ensure affordable access to the Internet, large, high-quality, advanced production capacity assurance is indeed a top priority for photovoltaic development.
In March 2017, TÜV Rheinland simulated the harsh environment of five regions including Cologne, Germany, Datong, China, Kumamoto, Japan, Chennai, India, and Los Angeles, USA. It completed the strict simulation test and completed the PV Module Power Generation Simulation Competition. The power generation test concluded that 60 pieces of Longji Leye single-crystal components confirmed the advancement of single-crystal module productivity with the first actual total power generation data.
Once upon a time, single-crystal components that could not be used for cost-impacting have become a thing of the past. Through the improvement of the industry's upstream processing of silicon materials in the industry, silicon wafer manufacturing has drastically reduced costs, and a path leading to the pursuit of high efficiency has immediately opened up.
From 2015 to 2017, it is not only the period of rapid global photovoltaic growth, but also the leapfrogging phase of China's photovoltaic industry from a single pursuit of scale to efficient transformation and development.
According to statistics, in 2017, the global installed capacity was 102 million kilowatts, the global single crystal accounted for 27%, the domestic installed capacity was 53 million kilowatts, and the domestic single crystal accounted for 36%, which was significantly higher than in the past. According to industry sources, from the domestic single in 2014, The fraction of crystals is less than 5%. In less than three years, the advantages of single crystals continue to show an increase in the proportion, which is affected by the surge of '630' in the first half of 2017. In the event that the supply of single crystal modules is in short supply, To reach 36%, otherwise the proportion of single crystal components will exceed 40% in 2017.
Layout of high-quality advanced production capacity can benefit from the current, more decisive than the future. Under the expansion of production capacity, the continuous refresh of the efficiency of single-crystal batteries and components has become a proof.
In 2017, the conversion efficiency of single-crystal cells reached 23.26%, and the efficiency of the experimental line was leading. The single-crystal double-sided PERC cell has a double-sided rate of 82.65%. In January 2018, the PERC single crystal module conversion efficiency was 20.41%, and the technology leader achieved a perfect score.
As a long-term commitment to monocrystalline product research and development, Longji Leye has a single-crystal silicon wafer production capacity of 15 million kilowatts in 2017. To meet the demand for high-efficiency products in the global market, the wafer production capacity in 2018 will increase to 28 million kilowatts, relying on Lijiang, Yunnan. Chuxiong, Baoshan added 10 million kilowatts of monocrystalline silicon wafer production capacity. It will expand to 36 million kilowatts in 2019, and will expand to more than 40 million kilowatts by 2020. In 2018, single crystal modules will have a capacity of 12 million kilowatts.
