As the world's largest PV exhibition, 2017SNEC International Solar Industry and Photovoltaic Engineering Exhibition is currently in hot in Shanghai, and many PV companies are bringing new PV products to the show. The most hot discussion in the photovoltaic industry is the battle between monocrystalline silicon and polycrystalline silicon. At this exhibition, the above debate is still the focus of discussions between photovoltaic companies and industry experts. In the eyes of the industry, behind the fierce competition between monocrystalline silicon and polycrystalline silicon, the price of photovoltaic modules has been greatly reduced, and the cost of photovoltaics has further declined. This will bring about the advance of photovoltaic parity online.
Single crystal and polycrystalline competition intensified
GCL-Poly released a new generation of ingot single crystal G3 wafer products at the Shanghai SNEC International Photovoltaic Exhibition, which opened on April 19th. This product uses ingot technology to produce monocrystalline silicon wafers with high productivity and high efficiency. Multiple advantages such as low cost and low light decay.
According to the introduction of GCL-Poly, the ingot monocrystalline silicon wafer G3 is based on the latest single-single-crystal technology platform of GCL-Poly, and the single crystal area of ​​the silicon wafer can reach more than 99%. Among them, the mass conversion efficiency of the whole-single-crystal monocrystalline silicon wafer G3 under the conventional process can reach 19.52%, and can reach 20.85% under the PERC battery process, and the efficiency of the straight-drawing single crystal silicon wafer with the same process does not exceed 0.5. Percentage points. Compared with the straight-drawing single crystal silicon wafer of the same side length, the whole single crystal silicon wafer has a larger area and the package loss is smaller. The G3 silicon wafer 60-piece module of the ordinary single crystal cell process can reach 280~285 watts, and the PERC process can reach 295~300 watts.
In this regard, Geng Liexie Chief Technology Officer Wan Yuepeng told the "Daily Economic News" reporter, "Ingot monocrystalline silicon wafer G3 through technology upgrade, the conventional polycrystalline high capacity, low light decay and low package loss, As well as the advantages of high conversion efficiency, low dislocation density, and matching high-efficiency battery technology of traditional CZ single crystals, it is expected to become the most competitive high-efficiency photovoltaic product in the future."
In addition, Longji shares also announced new products at the exhibition. The new single crystal product is called Hi-MO2. The product has three highlights of high power, high power generation and low LCOE, which will open a new era of high-efficiency single crystal PERC double-sided power generation technology. Among them, Hi-MO2 is a double-sided power generation product based on single crystal double-sided PERC technology. The power of 72 type components is 360/365W, and the power of 60 type components is 300/305W. The front side of the battery has a power generation efficiency of more than 21%, which is comparable to a single-sided PERC battery. At the same time, the back is made of glass, which realizes double-sided light receiving and double-sided power generation. The back power is not less than 75% compared with the front power. The back of the product can bring up to 25% of the power generation gain (depending on the system design and ground characteristics), which can bring higher profits to power station investors.
At the same time, according to the "Daily Economic News" reporter learned from Jingke Energy, at this exhibition, Jinko Energy launched a PERC high-efficiency single crystal module, MTC double-glass polycrystalline components, MTC high-efficiency polycrystalline components, etc. New product. According to the rough statistics of the reporters of “Daily Economic Newsâ€, more than 10 PV companies have launched new single and polycrystalline products at the exhibition.
It is worth noting that since the PV front runners' plan policy tends to be monocrystalline silicon, after the leader plans to implement it, monocrystalline silicon is rapidly vying for the polysilicon market. Currently, the market for single crystal and polycrystalline is 2:8.
This time, many new single crystal nuclear polycrystalline products were launched at the Shanghai SNEC International Photovoltaic Exhibition. This is tantamount to further aggravating the already fiercely competitive PV module market. "The single crystal is now rising rapidly, but it is also Does not mean that the polycrystalline market will continue to be compressed, because polysilicon companies are also improving the technology of polysilicon, further compressing the cost of polysilicon, thereby reducing the price of polysilicon. At the same time, polysilicon companies are also actively responding to new single crystal products. The impact of crystalline silicon, so the market competition will be very fierce, but the polysilicon market will not be further compressed." Photovoltaic industry insider Tian Dayong told the "Daily Economic News" reporter.
A problem that cannot be ignored is that although the rising trend of single crystal is fierce, the price of single crystal is higher than the price of polycrystalline, which also restricts the momentum of single crystal to some extent. According to the announcement issued by Zhonglai Co., the average contract price of N-type single crystal components reached 3.38 yuan / watt, while in the case of polycrystalline, the new quotation of GCL, the average price of mainstream 270 watt high-efficiency polycrystalline components is 2.8 yuan / watt. . The comparison shows that the price of the single crystal module exceeds the polycrystalline component by 0.5 yuan to 0.6 yuan / watt.
PV parity online or early arrival
Regardless of the fierce competition between single crystal and polycrystalline, one phenomenon that cannot be ignored is that the price of photovoltaic modules will be lowered with competition, and the subsequent decline in photovoltaic costs.
According to China's "13th Five-Year Plan", by 2020, the cumulative installed capacity of photovoltaics will reach 105GW. At the same time, the price level of photovoltaic power generation will drop by 50% on the basis of 2015. “The scale of 105GW will far exceed by 2020, which is an inevitable result. The domestic market has been completely opened, which is for single crystal and polycrystalline enterprises. Providing many opportunities, but single crystal and polycrystalline enterprises should improve technology research and development, and through technology advancement and product innovation, the cost of batteries, components and the entire photovoltaic system will continue to decline, which will help PV affordable Internet access.†General Manager of Jinneng Technology Yang Liyou told the reporter of "Daily Economic News".
In addition, Gao Jifan, chairman of Trina Solar, said in the “Global PV Leaders Dialogue†that with the rapid decline in power generation costs in the photovoltaic industry, we may see that in the next five years, photovoltaic power generation in most parts of the world will go to parity. The energy prices of photovoltaics and solar energy will also drop significantly, and PV prices will be available online by 2020.
In Sun Xingping, president of GCL New Energy, it is necessary to lift the restrictions on non-photovoltaic factors and to form a friendly environment conducive to the development of the photovoltaic industry. Vigorously developing photovoltaic power generation as a green energy has become a consensus of all walks of life in recent years. To achieve parity online access, it requires the efforts of the entire photovoltaic industry, and it also needs to work together with policy innovation.
According to data from China Photovoltaic Industry Association, from 2013 to 2016, China's silicon material cost decreased by 44.4%, component cost decreased by 41.6%, inverter cost decreased by 57.1%, and system bare price decreased by 27%.
In this regard, Wang Bohua, secretary-general of China Photovoltaic Industry Association, told the reporter of "Daily Economic News": "As the cost of components declines, the cost of photovoltaics will continue to decline, although non-photovoltaic costs will affect the process of PV parity online to a certain extent. However, according to the target plan, China's photovoltaic power generation will achieve a cheaper Internet access on the user side in 2020, and achieve a cheaper Internet access on the power generation side in 2025. The current industry production costs are rapidly declining, and now the outlook for affordable Internet access may be realized ahead of schedule."
