Mobile WebSiteAt 2017 Shanghai Photovoltaic Show, exhibitors are introducing the latest PV panel products to buyers.
As the world's largest photovoltaic power, China's photovoltaic industry in the future will expand the scale into a secondary position, efforts to promote technological progress, cost reduction efficiency. At the same time, it is necessary to fill the development of distributed photovoltaic short board, increase the installed capacity and market size of distributed photovoltaic power generation, develop the PV products suitable for distributed market, give full play to the advantages of distributed photovoltaic power generation, safety and environmental protection and high power generation .
Recently, the world's most influential photovoltaic event SNEC eleventh (2017) International Solar Energy Industry and Photovoltaic Engineering Exhibition in Shanghai came to an end. Exhibition, in the competing release of new products, "distributed" to become the major manufacturers frequently lexical vocabulary. Many people in the industry expect that after the last year's substantial growth, distributed photovoltaic will usher in a real outbreak period, into the centralized and distributed power generation stage of China's PV will be widening.
Technological innovation and efficiency
China PV Industry Association data show that in 2016 China's new PV installed capacity reached 34.54 GW, for four consecutive years ranked first in the world. "If the 'second five' the most important task is to expand the scale, 'thirteen' during the expansion of the scale will be placed in a secondary position." National Energy Board, deputy director of new energy and renewable energy Xingyi Teng revealed that the next step Mainly to promote technological progress, reduce costs, expand the diversified applications, cost reduction, give full play to the role of state subsidies.
In the country to vigorously promote the photovoltaic industry under the background of efficiency, single crystal technology with higher power generation efficiency gradually favored by the manufacturers. The exhibition, GCL-Poly released a new generation of ingot single crystal G3 silicon products, the product based on GCL-Poly's latest single-crystal technology platform, mass production of the whole ingot monocrystalline silicon wafer G3 in the conventional process Under the battery conversion efficiency of up to 19.52%, with "high capacity, high efficiency, low cost, low light failure" and other multiple advantages.
Longji shares also released a single crystal product called Hi-MO2, the product has high power, high power and other highlights, the battery power generation efficiency of more than 21%; the same time, the back of the glass package, to achieve a double-sided light, double Surface power generation, the back can bring up to 25% of the power generation gain, for the power station investors to bring higher returns.
Prior to the main production of high efficiency polycrystalline crystal components of the crystal energy, this exhibition also introduced the market's highest power PERC efficient single crystal components, the N-type double-sided components through the back to absorb reflection and scattered light gain, the actual power generation efficiency can be improved 10% to 30%.
In the single crystal products frequently force at the same time, some manufacturers are constantly innovating the performance of polycrystalline products. "At present, the global PV industry chain is still facing low-end excess capacity problems, but efficient and ultra-efficient production capacity is always scarce." Jin Neng Technology General Manager Yang Liyou told the "Economic Daily" reporter, in order to ease the market demand for efficient photovoltaic products , Jin can continue to enhance the efficiency of polycrystalline technology, reduce manufacturing costs, the third quarter of this year is expected to mass production 280W components. With the widespread use of diamond technology, polycrystalline costs will be further reduced by 5% to 8%.
Distributed photovoltaic prospects
Since China officially launched the domestic PV market, has been committed to promoting the concentration and distributed PV two markets simultaneously, but for various reasons, distributed photovoltaic development seriously lagging behind. Until last year, this market pattern began to change. Data show that last year, distributed installed capacity of photovoltaic power generation than in 2015 increased by 200%.
"At present, China's PV industry market structure and market layout has changed significantly." Trina Solar chairman and chief executive officer Gao Ji Fan said that the new market focus from the western region quickly moved to the central and eastern regions, from the ground power station to distributed , Especially after August last year, the monthly distribution of distributed projects accounted for almost 50% of the total amount of co-grid.
"Solar energy development," thirteen five "plan" clearly pointed out that by the end of 2020, the domestic solar power installed capacity to reach 110 million kilowatts or more, of which distributed photovoltaic installed capacity of more than 60 million kilowatts, the end of 2016 distributed cumulative installed capacity of only 1032 million kilowatt. This means that the next four years, distributed photovoltaic every year more than 10 million kilowatts of market size. At the same time, distributed photovoltaic also has 20 years of national subsidies to support, in the centralized power plant prices continue to cut and discard the power of the case, the distributed advantages obvious.
Based on this, in this year's SNEC show, manufacturers have introduced for the distributed market of photovoltaic products. Jingke Energy put forward the concept of ultra-high reliability, the new 6 new components of the product efficient, durable, beautiful appearance, can be applied to the roof, fence, complement each other, agricultural light complement, agricultural roof and other building integration and Distributed power generation system. "Efficient features especially make new products more suitable for distributed power plants." Crystal Energy CEO Chen Kangping said.
Due to a large installed capacity of industrial and commercial roofs is extremely limited resources, some companies use their own advantages to find a different way to build a variety of forms of distributed power plants. Tongwei Group as the world's largest aquaculture enterprises and domestic major solar cell business, creatively combine the two main business, promote the "fishery one" project.
Tong Huibang Group Vice President Hu Rongzhu said that Jiangsu Nantong Rudong project, for example, a construction of 10 megawatts of photovoltaic power plants, each year about 13 million kilowatts of electricity, 2720 acres of the latter part of the completion of the total installed capacity of up to 80 trillion watt. "Can be power, the next fish can be" and "fishing light one" model brought about by the overall power generation income and farming income, users can improve the overall efficiency of 10 times.
Civil market into a focus
Distributed photovoltaic according to the size of installed capacity can be divided into industrial and commercial distributed, household distribution, due to building standards and quality issues, China's installation of photovoltaic power plants meet the requirements of industrial and commercial roofs accounted for only 20%, which makes nearly two years for roof resources Snatching intensified. At the same time, all over the suburbs and rural areas of the household roof has become a dig to be mine.
The exhibition, Trina Solar, Jingao and other mainstream manufacturers invariably launched a family of photovoltaic power plant system, and the focus of the center of the booth to promote, to consult the residents of the user is also an endless stream. In order to further meet the needs of customers in the home PV market, Crystal Australia will be home products from a single component of the product upgrade to complete sets of home photovoltaic power generation system, an effective solution to the user due to the use of different manufacturers of components, inverters, distribution boxes and other equipment Power station caused by poor matching, low after-sale protection, operation and maintenance costs are high, low power plant revenue problems.
"After 20 years of development, the cost of photovoltaic power generation has dropped to 5% of the original, already have the conditions to the tens of thousands of households." Gao Ji Fan said, according to our survey, China's existing solar household roof can be installed 150 million ), In accordance with the installed capacity of 3 kilowatts per household, the total cost of 30,000 yuan, which is a particularly large market. For the people, in the roof to build a photovoltaic power plant, the annual rate of return can reach about 15%, is a way to increase the family income.
With the unique advantages of thin film technology, Hanergy Group in the civilian market to go further. With its ability to upgrade technology and the huge market demand for mobile solutions, Hannon has introduced portable thin-film solar products for thin-film solar power generation paper, power generation kits, power generation backpacks, and small off-grid power generation systems for different market needs.
"This year is the real first year of the distributed PV market, but also the real first year of the mobile energy market, the development of this market will be much faster than we imagined." Han Hui thin film power generation group vice president Xu Xiaohua that, with the energy Internet and The development of mobile energy, the past, the form of centralized supply of energy will be completely changed. The future, every roof of a building, the roof of each car, and even every bike can generate electricity, you can also trade on the grid. (Economic Daily, China Economic Net reporter Wang Yichen)
