On July 10, Dongfang Risheng announced that the groundbreaking ceremony for the annual production of 5GW high-efficiency photovoltaic module manufacturing base project was held in Yiwu, Zhejiang. It is understood that the project will mainly produce single-double glass PERC battery components, and it is expected that monocrystalline battery components will be assembled. The package power can reach up to 400W, which is one of the highest power products in the industry. This will provide an advanced technology path to promote the cost of photovoltaic power generation and accelerate the price of photovoltaic power generation.
It is reported that the manufacturing base will be located in Yiwu Information Optoelectronics High-tech Industrial Park. The total project area is about 300 mu, and the construction period is 3 years. It will be divided into two phases for construction. Among them, the first phase 2GW project design plan will consider the follow-up technology development. Route, keep the production line to meet the large market fluctuations, and mass produce various PV modules that meet the requirements.
At the beginning of the project design, Dongfang Risheng will continue to promote the industry to achieve cost reduction and efficiency through diversified technology combination. After comprehensive consideration, the company will focus on double glass 5BB/6BB high power single and double glass lightweight components, low current and high power. Components, high-reaction and high-efficiency double-sided power generation components technology, MBB high-power generation low-cost components and MBB multi-chip ultra-efficient component technology several major technical routes.
According to the person in charge of Dongfang Risheng, more MBB main-gate batteries can realize a shorter current transmission path for MBB high-power generation and low-cost component technology, and further reduce the packaging cost of the battery components while improving the power of the battery components. In the early stage, considering the upgrade and compatibility of equipment, it can be realized only by simple modification; for MBB multi-chip ultra-efficient component technology, the company will further upgrade based on the above technology, mainly for ultra-efficient bases and projects with ultra-high power requirements. Solution products, to achieve 'lower cost + increase efficiency' two in one.
Due to the comprehensive consideration of the subsequent technological development, Yiwu high-efficiency component manufacturing base will also increase compatibility in equipment development, in which the whole line is compatible with single and double glass components, single and double-sided components, 156 batteries, 165 batteries and other products. Production, welding machine compatible with 5/6/MBB battery welding. The whole workshop realizes intelligent information management. Through the use of information MES integration technology, the data can be truly reliable and analyzable. It is expected that the per capita annual production capacity will reach 5MW or more after the completion of this workshop. Higher than the current industry average of 1.7MW.
Since the introduction of the New Deal, both the upstream and the downstream of the industry have faced certain pressures. The industry as a whole has also scaled from the scale, the speed, the price to the quality, the technology, the efficiency, and accelerated the realization of affordable Internet access. Based on this, Dongfang Risheng said The implementation of Yiwu high-efficiency battery module manufacturing base will further promote the development and production of upstream crystalline silicon solar cells and the production and promotion of downstream solar terminal applications. At the same time, this will also help to enhance the core competitiveness of the domestic solar photovoltaic industry. Conducive to the integration and efficiency of technology research and development and production resources, enhance China's initiative in the development of the global solar photovoltaic industry.
