On January 16, Dongfang Huan Sheng Co., Ltd. released its efficient shingled module products.
It is reported that this is the first high efficiency shingwa components product release, component conversion rate as high as 19.6%, is the world's highest conversion rate of P-type components, is the future of photovoltaic advanced technology leader.
Eastern Ring Sheng is located in Yixing Economic and Technological Development Zone, Jiangsu Province, China Eastern Electric Group Co., Ltd., Tianjin Central Semiconductor Co., Ltd. co-funded the establishment of photovoltaic products manufacturing enterprises.Since August 2015 since its establishment, has created a highly efficient single crystal PERC Battery and efficient shingling components two outstanding photovoltaic product line.
It is reported that the traditional components using tin-coated copper tape to complete the electrical connection between the cells, the chip space can not make full use of sunlight.Traditional components using series circuit design, internal resistance larger components, high power loss.Traditional components output power and Power generation has some limitations.
The launch of the efficient shing Wah components products, is based on the efficient single-crystal PERC battery technology, the use of advanced shingwa technology, bid farewell to the traditional components of the traditional welding methods, with parallel circuit design and no main gate battery design, more High efficiency, high reliability, high power generation, lower system costs, long-term warranty outstanding features, component power breakthrough 400W.
Specifically, efficient stacking technology has four major advantages.
① high efficiency
High efficiency shingled assembly by slicing 6 pieces of conventional cells, and then forming a long string together in series, after the six battery strings in parallel design, reducing the internal resistance of the assembly, reducing the power consumption within the assembly while passing The innovative array arrangement reduces the conventional chip spacing and increases the light-receiving area. The conversion efficiency of single-crystal PERC high efficiency shingled modules can reach more than 19%, 13% more power than the conventional single crystal PERC modules. The leading technology leader base Claim.
② more power generation
High-efficiency shingles with no-to-shingled and shielded battery connections ensure ample current paths, reduce component power dissipation and generate more power than conventional components at the same life cycle. Parallel shunt designs reduce power to shingles It has a linear relationship with shaded area and performs better under partially shaded conditions than other conventional components. It is more suitable for high-latitude areas, land-intensive projects, and distributed systems.
③ high reliability
The unique flexible connections of the shingles minimize the possibility of cracking of the cells due to component transport and field installation and control the crack propagation. The ribbon-less design effectively circumvents the maximum failure factor of conventional components - ribbon Layering and corrosion, making the components have good performance in various reliability experiments.Currently ring Sheng components decay rate below 2.5%, with an average annual decay rate of less than 0.55%, with 25 years of product cycle up to 84.3 %.
④ low cost
High-efficiency shingling modules help to realize the photovoltaic 'electricity grid parity' during the 13th Five-Year Plan period, which can save 10% of the DC system cost in the installation of power stations. In addition, the shingled components are also suitable for the future thinning of silicon and large silicon wafers Photovoltaic reduction strategy laid the foundation for victory, leading the future of photovoltaic innovation!
Xu Hailiang, Vice President of TÜV SÜD Greater China Smart Power and Photovoltaic Department, announced at the press conference that the shingled components passed the certification and pointed out that the conversion rate of the products of the East Huan Sheng efficient shingled components was as high as 19.6%, providing 25-year power guarantee commitment and one- TÜV SÜD certification, the future leader in advanced photovoltaic technology!
Dongfang Huan Sheng chairman Lin Guangping said that the end of 2017, Dongfang Huan Sheng PERC single crystal cell production capacity exceeded the GW level, while efficient shing Wah assembly line three production lines, with 750MW capacity, the first 51MW products have been sold Overseas, and will quickly reach an annual output of 5GW efficient production of shingled components.
Wang Si-cheng, researcher of the Energy Research Institute of National Development and Reform Commission and Wang Bohua, secretary-general of China Photovoltaic Industry Association, also made a professional interpretation of Dongfang Huan Sheng efficient shingled module products, including Guodian, Huadian, Huaneng, Three Gorges, Construction, China can build, Shanghai Electric Power, Mongolia Group, also participated in the power generation group conference.
