Lightweight MBB technology

Accurate craftsmanship ensures superior performance, with strict control at every step.

Half-cut multi-busbar (MBB) technology

By utilizing round wire ribbons, shading from the ribbons on the photovoltaic cells is reduced, making full use of the reflection principle of the ribbon to increase the conversion efficiency of the modules.

Our advantages

Gentle solution

Lightweight at 2.9 Kg/m², 70% lighter than conventional modules, reducing the load burden on the roof. Its flexibility accommodates a wider range of installation scenarios.

High salt spray resistance

Self-developed polymer material encapsulation and a full-screen borderless design effectively resist salt mist corrosion.

High reliability

Degradation under 2x IEC standard testing is lower than that of regular glass modules; 7000H high temperature and high humidity testing degradation < 8%.

Anti-glare design

Matte surface material and light-trapping pattern design significantly reduce light pollution and enhance response to low-light conditions.

Product advantages

Light weight: lightweight PV modules can weigh as little as 2.9 kg/m², making them easier to handle and install, especially suitable for buildings with limited roof load-bearing capacity.

Easy installation: the lightweight nature simplifies the installation process, requiring minimal training for installers.

Aesthetics: the materials and design of lightweight modules result in a more attractive appearance that does not detract from the building's exterior.

Safety: due to their light weight, they impose lower load requirements on the roof, reducing safety hazards associated with inadequate roof load-bearing capacity.

Customizable design: the shape, size, and color of lightweight PV modules can be adjusted, enabling customized design and production.

Cost-effectiveness: lower transportation costs for lightweight modules and reduced labor installation costs due to easy installation lower overall expenses.

Broad application range: lightweight PV modules are suitable for various applications, including lightweight roof markets, BIPV (Building Integrated Photovoltaics), mobile power, robotics, and outdoor activities.

These advantages of lightweight PV modules make them increasingly valued in the distributed PV market, particularly in scenarios where there are restrictions on roof load-bearing capacity or special aesthetic requirements.
