Multi-Busbar PV String Welding Machine with peak power of 45 kW in compact laser welding equipment featuring advanced control capabilities.

This automated production equipment specializes in string welding PV crystalline silicon solar cells, delivering high production capacity, precision, and compatibility.

Beijing X-Solar Energy Co., Ltd. was founded in 2020 and is headquartered in Beijing. As a science and technology innovative energy enterprise, the company specializes in 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 established its first demonstration factory, Jiangsu X-Solar Green-building Technology Co., Ltd., in Jiangyin CNBM Jetion Industrial Park. Simultaneously, Jiangsu YuanTeng FengSheng Intelligent Manufacturing Technology Co., Ltd., a wholly-owned equipment company, delivered the world's first "three-in-one" automatic production line for the Jiangyin base. This production line is compatible with three product categories: X-Solar Light shadow series (flexible PV modules), X-Solar Light rhyme series (building PV tile modules), and X-Solar Light Curtain series (building PV wall modules), along with customized products.

X-Solar PV series products integrate architectural aesthetics, comply with design specifications, and create energy value, earning widespread recognition and praise from domestic and international customers.

In 2024, the company expanded with regional centers in Shanghai and Guangzhou, established the Hong Kong X-Solar Future Energy Research Institute, and set up overseas sales companies in Australia, Italy, Germany, Saudi Arabia, and Argentina. The company has launched a global布局 to provide sustainable energy products and services worldwide, contributing to "carbon neutrality and carbon peak" goals.

It achieves series connection of battery cells by precisely positioning photovoltaic battery cells with multiple busbars through high-precision mechanical transmission cooperating with the welding system, using appropriate welding processes (such as infrared welding, laser welding, etc.) to weld busbars onto the main grid lines of the battery cells.

Multi-busbar technology reduces current transmission distance on the battery cell surface, decreases resistance loss, improves photoelectric conversion efficiency, and increases module power output.

Common methods include infrared welding (uniform heating, relatively fast welding speed) and laser welding (high precision, good welding strength, but higher equipment cost). Different processes suit different production requirement scenarios.

Precisely control parameters such as welding temperature, pressure, and time; regularly calibrate welding equipment; ensure battery cells and busbars have clean, flat surfaces; and use qualified quality materials.

Check all equipment part connections, electrical system for faults, transmission part operation smoothness, clean welding work area, and confirm welding materials (busbars, etc.) are fully prepared.

Check alarm prompt information and determine if the problem stems from electrical faults, mechanical faults, or abnormal welding parameters according to the equipment operation manual. If resolvable, follow manual steps. If not, contact professional maintenance personnel immediately.

Optimize welding parameters to reduce welding time, perform regular equipment maintenance to minimize shutdowns, arrange production batches reasonably, and improve operator proficiency.

Different models and configurations have varying production capacities. Generally, thousands of battery cells can be welded per hour. Specific capacity depends on equipment design specification parameters.

Regularly clean surface and internal dust/debris, lubricate transmission parts, check welding head wear condition, calibrate welding parameters, and inspect electrical line connections for looseness.

Recommend comprehensive maintenance every 1 to 3 months based on equipment usage frequency to ensure all performance aspects remain optimal for stable operation.

Conduct appearance inspections for welding joint firmness and issues like poor welding or detachment. Use professional electrical testing equipment to detect whether electrical performance indicators such as series resistance meet standards.

Analyze defect causes. If due to process parameters, adjust parameters promptly. If material-related, replace with qualified materials. Mark defective products, store separately, and handle according to relevant rework or scrapping procedures.
