On April 25, a seminar on Re-empowering countermeasures and introduction cases for the solar power generation industry hosted by Enabiz Inc. (Enabiz Inc.) was launched online. Employers and industry experts from around the world discussed and shared how to re-empowering solar power generation facilities through Increasing power generation, reducing maintenance costs and increasing power trading revenue. Zhejiang WINHITECH New Energy Co., Ltd. ("WINHITECH") was invited to participate in this online meeting. At the forum, Delia Di, Overseas Sales Director of WINHITECH, shared the latest HJT technology with the experts and guests present, and published a report titled "The Necessity of HJT Industrialization". Delia Di said that With the industrial upgrading of the global green energy market and the continuous reduction in the cost of N-type modules, HJT technology continues to show great advantages in the photovoltaic market with its high-efficiency, low attenuation and low-cost potential. BNEF predicts that the permeability of HJT modules will exceed 30% in 2025. Compared with TOPCon and PERC technologies, the current mainstream 210-type HJT has better performance in terms of BOS (balanced system cost), module cost and other costs, making it absolutely superior in levelized cost of electricity (LCOE) in the power system.  As one of the global promoters of HJT technology, WINHITECH has always focused on technological innovation and quality management. Currently, it has built green energy products and comprehensive energy solutions and services based on high-efficiency monocrystalline cells and high-efficiency HJT modules. There are more than 100 users around the world including Japan, Germany, the Netherlands, and Malaysia. The world's four major production bases and five factories will reach an industry-leading production capacity of 30GW of cells and 15GW of modules in the next three years.

The outdoor empirical data of WINHITECH‘s’ HJT modules in the first quarter of 2024 was officially released. Data provided by the National Photovoltaic Quality Testing Center (CPVT), a third-party authoritative organization, shows that when operating in an environment with an average temperature of 10.8°C, compared with TOPCon modules, the cumulative gain in power generation per watt of WINHITECH's 210HJT-66 module has reached 2.14%. As the ambient temperature gradually increases, the power generation gain of HJT modules will reach more than 4%, which is an obvious advantage. HJT modules rely on their advanced technological advantages such as excellent low attenuation rate, ultra-low temperature rising loss, significantly high bifaciality , and excellent low irradiance performance. They have been tested on outdoor empirical test platforms of multiple authoritative institutions. , all demonstrating the excellent power generation capabilities of heterojunctions. This demonstration project is located at the CPVT Yinchuan base, using WINHITECH's 210HJT-66 module and the industry's leading company TOPCon module. Installation angle is 40°, the lowest point of the module is 1 meter from the ground, and the ground is ordinary sand. Data collected from late January 2024 shows that the single-watt power generation gain of WINHITECH's 210HJT-66 module compared to TOPCon modules is gradually increasing, the single-watt power generation gain has reached 2.14%. The advanced technical advantages of HJT modules such as high bifaciality, low temperature coefficient, excellent low irradiance performance and low attenuation rate are all conducive to the excellent power generation capabilities of heterojunction modules. Through a combination of empirical data and basic theory analysis, HJT’s gain over TOPCon mainly comes from two aspects: 1.Gain of high bifaciality Considering various outdoor installation scenarios, there are no special restrictions on the installation conditions. Conventional 3 beams are used for shielding installation on conventional sandy ground. Through actual data measurement, WINHITECH's 210HJT-66 module has bifaciality 10% higher than that of TOPCon modules. The occlusion of the back beam results in a 50% gain loss. The overall bifaciality advantage brings a power generation gain of 0.5%~1.0 %. According to calculations, if choose the cement floor + no blocking method on the back, the bifaciality gain can reach 2.0%~3.0%. Back beam shielding verification: When three beams are blocked, only about 50% of the power on the back of the module remains. Therefore, when designing and calculating costs for actual power stations, installation methods with little or no obstruction on the back can be considered to give full play to the advantages of HJT’s ultra-high bifaciality. 2.Temperature coefficient gain The temperature coefficient of WINHITECH's 210HJT-66 module is -0.24%/℃, while that of TOPCon modules is -0.29%/℃. The power loss of HJT at high temperatures is about 0.05%/℃ lower than that of TOPCon modules. Therefore, the higher the ambient temperature, the greater the single-watt power generation gain of HJT modules relative to TOPCon modules. According to monitoring data in February, the average ambient temperature was only 4.7°C. The internal temperature of the module is mainly affected by the internal current of the module. When the irradiance increases, the ambient temperature increases from 1.2°C to 7.6°C, and the module temperature increases from 6.7°C to 30.5°C. Therefore, when the modules are working normally, the modules are at a relatively high operating temperature. When the module temperature reaches 60°C, the temperature coefficient gain can reach 1.75%. In summary, based on the actual data collected in the first quarter, HJT modules have a single-watt gain of 2.14% compared to TOPCon modules. The increase in temperature brings lower power loss, and the overall power generation advantage will reach 4%. by overlay installation method,  increasing the gain of backside power, the overall advantage will reach 5%. WINHITECH is committed to in-depth research into the actual outdoor performance of HJT modules under diverse geographical and climatic conditions, and provides actual data for customers to select products. The company has established strategic partnerships with many well-known third-party institutions such as CPVT, CTC and CHINA HUANENG. We jointly launched outdoor demonstration projects in different representative regions such as Yinchuan, Hainan, and Jiayuguan. In addition, WINHITECH is actively planning to build outdoor demonstration power stations in more challenging areas such as Yantai (marine environment) and Chonburi, Thailand (equatorial climate) to cover a wider range of special climate areas. Through demonstration projects, WINHITECH will systematically collect and analyze data related to power generation and climate conditions, comprehensively evaluate the actual performance of products in different climate environments, and fully grasp the performance indicators and uniqueness of HJT modules. The company will continue to promote technological innovation and product optimization to ensure that HJT modules can achieve optimal power generation efficiency in various environments and bring greater benefits to customers.

Use actual power generation data to prove HJT, and help terminals better understand the product in the process of reducing costs and increasing efficiency. " Zhang Xiong, executive deputy general manager of Raymysolar: "The market price war is becoming more and more fierce, and the advantages of heterojunction's high power generation have been buried by public opinion. Empirical data should be released on a large scale to make the market aware of the high power generation of heterojunction. At the same time, we will gather the clubs to jointly reduce costs and work together to reduce costs in multiple links to gradually increase market share.” Zhang Jinjian, Vice Chairman and Chief Operating Officer of AKCOME : “The advantage of the alliance is that we advance together and retreat together. Therefore, we can formulate a unified price line that can maintain the development of the enterprise and have a competitive advantage in the market, and expand the proportion of installed capacity. , improve terminal recognition and then gradually make cost-effective products to increase corporate profit margins.” Chu Yifan, Chairman of OW SOLAR: “Concentrate on the role of the alliance to promote cost reduction and increase efficiency,  support everyone’s ideas and plans for unified publicity, unified price lines, and collaborative cost reduction. Monthly meetings among alliance members can also ensure that these tasks are advanced in an orderly manner. We are very confident about the future of HJT technology.” Zhao Xuewen, Chairman of Photovoltaic New Energy: "Industrial competition is not only fierce, but also trapped in a whirlpool of homogeneity. Heterostructures are harmonious but different, and low-carbon, high-efficiency are the core advantages. If the propaganda caliber can be unified and lowered in the mainstream such as 0BB Working together in this technical direction, I believe we can create a differentiated path to advancement. Ni Zhichun, general manager of WINHITECH: "We all know that heterojunction has leading comprehensive advantages, such as high efficiency, low temperature coefficient, low degradation, long-term stability, etc. We have actually realized these advantages in research and development as an enterprise. This is why we are so firmly committed to this track. We hope that with the help of the alliance, more customers can experience the advantages of heterojunction technology.” At the end of the roundtable, the club members reached a consensus on the trend of cost reduction and efficiency improvement, and enriched their in-depth and multi-faceted understanding of specific issues, which will greatly facilitate subsequent more effective cost reduction and efficiency enhancement actions and fully highlight the high-efficiency advantages of heterojunction technology.
