It's a science and technology innovative energy enterprises with the main business of future cell R&D, flexible photovoltaic modules, building photovoltaic module production, high-end equipment manufacturing, production line delivery, and AI-CITY wisdom energy management services.
In July 2023, the company's first demonstration factory, Jiangsu X-Solar Green-building Technology Co., Ltd., was established in Jiangyin CNBM Jetion Industrial Park. Meanwhile, Jiangsu YuanTeng FengSheng Intelligent Manufacturing Technology Co., Ltd., a wholly-owned equipment company of the company, delivered the world's first "three-in-one" automatic production line for Jiangyin base. The production line can be compatible with the production of three categories: X-Solar Light shadow series (flexible PV modules), X-Solar Light rhyme series (building PVtile modules), X-Solar Light Curtain series (building PV wall modules), and customized products. X-Solar PV series products have the advantages of integrating architectural aesthetics, complying with design specifications and creating energy value, which have been widely recognized and praised by customers in domestic and overseas.
In 2024, the company has added two regional centers in Shanghai and Guangzhou of China, and set up the Hong Kong X-Solar Future Energy Research Institute, and overseas sales companies in Australia, Italy, Germany, Saudi Arabia and Argentina. The company has launched a global layout to provide sustainable energy products and services to many countries, and has contributed to the "carbon neutrality and carbon peak".

Related to the basic principle of the equipment
1. Question: What is the working principle of the multi-busbar photovoltaic string welder?
Answer: It mainly realizes the series connection of battery cells by precisely positioning the photovoltaic battery cells with multiple busbars through high-precision mechanical transmission cooperating with the welding system, and then using appropriate welding processes (such as infrared welding, laser welding, etc.) to weld the busbars onto the main grid lines of the battery cells.
2. Question: What are the advantages of adopting the multi-busbar technology compared with the traditional one?
Answer: The multi-busbar can reduce the current transmission distance on the surface of the battery cell, decrease the resistance loss, improve the photoelectric conversion efficiency of the battery cell, and then increase the power output of the module.
Related to the welding process
1. Question: What are the commonly used welding methods and what are their characteristics?
Answer: Commonly used ones include infrared welding, which features uniform heating and relatively fast welding speed; laser welding has high precision and good welding strength, but the equipment cost is relatively high. Different processes are suitable for different production requirement scenarios.
2. Question: How to ensure the stability of welding quality?
Answer: It is necessary to precisely control parameters such as welding temperature, pressure, and welding time, regularly calibrate the welding equipment, and at the same time ensure that the surfaces of the battery cells and busbars are clean and flat, and the materials are of qualified quality.
Related to the equipment operation
1. Question: What preparatory work needs to be done before starting the equipment?
Answer: It is necessary to check whether the connections of all parts of the equipment are normal, whether there are faults in the electrical system, whether the transmission parts can operate smoothly, clean the welding work area, and confirm that the welding materials (busbars, etc.) are fully prepared.
2. Question: What should be done if a fault alarm occurs during the operation process?
Answer: First, check the alarm prompt information, and judge whether the problem is caused by electrical faults, mechanical faults or abnormal welding parameters, etc. according to the equipment operation manual. If it can be solved by yourself, handle it according to the steps in the manual. If it cannot be solved, contact professional maintenance personnel in time.
Related to production efficiency
1. Question: How to improve the production efficiency of the multi-busbar photovoltaic string welder?
Answer: Optimize the welding parameters to reduce the welding time, do a good job in the daily maintenance of the equipment to ensure few shutdowns due to failures, arrange production batches reasonably, and improve the proficiency of operators, all of which will help improve the efficiency.
2. Question: What is the maximum production capacity that the equipment can reach?
Answer: Different models and configurations of multi-busbar photovoltaic string welders have different production capacities. Generally, thousands of battery cells can be welded per hour. The specific situation depends on the design specification parameters of the equipment.
Related to maintenance
1. Question: What maintenance work needs to be done for the equipment on a daily basis?
Answer: It is necessary to regularly clean the dust and debris on the surface and inside of the equipment, add lubricating oil to the transmission parts, check the wear condition of the welding heads, calibrate the welding parameters, and check whether the connections of electrical lines are loose.
2. Question: How often is it more appropriate to conduct a comprehensive maintenance and overhaul?
Answer: It is recommended to conduct a comprehensive maintenance and overhaul every 1 to 3 months according to the usage frequency of the equipment to ensure that all aspects of the equipment's performance are good and it can operate stably.
Related to product quality
1. Question: How to test the quality of the products after welding?
Answer: You can conduct appearance inspections to see whether the welding joints are firm and whether there are problems such as poor welding or detachment. Professional electrical testing equipment can also be used to detect whether the electrical performance indicators such as the series resistance after welding meet the standards.
2. Question: How to handle the defective products after welding?
Answer: Analyze the causes of the defects. If it is a problem of process parameters, adjust the parameters in time. If it is a problem of materials, replace the qualified materials. Mark the defective products, store them separately, and handle them according to the relevant procedures for rework or scrapping.
