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".

FAQ
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.
