MBB (Multi-Busbar) + Half-Cell Technology

Utilizing a multi-busbar (MBB) half-cell monocrystalline cell design, this technology effectively reduces the internal operating current of the module, significantly reduces hot spot effects and line losses, improves overall output power, and enhances the module’s power generation performance under shading conditions.

High PID Resistant

Through the synergistic optimization of advanced battery technology and high-quality encapsulation materials, the module possesses excellent resistance to potential-induced degradation (PID), maintaining stable power generation efficiency over a long period even in harsh environments such as high temperature and high humidity.

Current Sorting Process

Precise current sorting and grouping of solar cells before shipment reduces mismatch losses between modules to less than 2%, maximizing system-level output and increasing the overall power generation of the array.

Ultra-Strong Mechanical Load Certification

Certified through extended wind and snow load tests:
Wind Load: 2400 Pascal
Snow Load: 5400 Pascal
Easily withstands extreme climates and harsh installation environments, ensuring structural safety throughout the power plant’s entire lifecycle.

1500V High Voltage System Compatible

The backplane and junction box fully support 1500V DC system voltage, which can reduce the number of strings, reduce the amount of DC side cables and combiner equipment, and effectively save BOS (System Balancing) costs.

Positive Tolerance Delivery Commitment

We commit to delivery with a positive tolerance of 0~+5W. The actual output power of each batch of components will not be lower than the nominal value, providing a certain guarantee for the return on investment of the project.
