The Optimal Choice for Perovskite Modules: QC Solar's New Junction Boxes

In the surging tide of the global transformation，clean energy is leading the sustainable development of society at an unprecedented pace. As a rising star in the photovoltaic industry， perovskite photovoltaic modules，with their outstanding photoelectric conversion efficiency, are regarded as an important indicator for future development.

However, due to the ultra-high open-circuit voltage and relatively small short-circuit current of perovskite modules, as well as the requirements for the installation methods of junction boxes in special module formats, the traditional Schottky diode and junction box structures are no longer fully applicable. Therefore, in order to precisely meet the booming demands in this field, QC Solar (301278.sz), relying on its profound industry experience and innovative technologies, has launched a series of junction box products specifically tailored for perovskite photovoltaic modules, safeguarding the future of green energy.

1.3Q Positive and Negative Electrode Integrated Junction Box: Flexible and with Excellent Performance

The 3Q junction box features a unique design of "one panel, one box" and a horizontal wire outlet structure (cables). It simultaneously provides both horizontal and vertical busbar dual wire outlet modes, flexibly adapting to various installation methods. It has built-in module diodes customized for perovskite modules, achieving precise matching and excellent performance. Meanwhile, this platform is compatible with traditional Schottky diodes ranging from 18A to 35A, fully meeting the diverse needs of customers.

2.091721-B Junction Box: Innovative Connection and Cost Optimization

Great wisdom lies within this small box! The 091721-B junction box adopts a streamlined design of "one panel, one box" and the wire outlet on the same side. The potting area of the 091721 - B junction box has undergone optimized innovation, significantly reducing the potting cost. Its low-profile and expandable exterior design enables it to meet the requirements of the vast majority of thin-film modules and also satisfies the high waterproof design requirements of perovskite.

3.102021 Junction Box: High Efficiency, Safety and Wide Applicability

The 102021 junction box offers two connection methods, namely spring crimping and welding, aiming to be as compatible as possible with various manufacturers. The side-pressed sealing waterproof ring enables the box body to easily meet the waterproof requirements without the need for potting, making it easier to install and reducing costs.

151943 Junction Box: Convenient Installation and Reliable Performance
The 151943 junction box adopts an integrated slender box body structure design of "one panel, one box". It is not only convenient for installation but also easy to hide behind the modules, achieving a perfect combination of aesthetics and practicality. It has three built-in bypass modules, which meets the structural design of installing several busbars in one box body, enhances the reliability of electrical connections, reduces losses, and provides an efficient and reliable solution.

5.BIPV Perovskite Junction Box: The Perfect Fusion of Aesthetics and Efficiency

The BIPV junction box is specifically designed for Building Integrated Photovoltaic (BIPV) systems. It offers two versions with different sizes, namely “one panel, one box” and “one panel, three boxes”, which not only meet the demands of different application scenarios but also ensure the simple and beautiful appearance of solar panels. It adopts advanced mechanical clamping connection technology, making the installation process more convenient and efficient. Whether it is a commercial building or a residential building, the BIPV junction box can easily integrate into them, adding a touch of green to green buildings.

Safe and Stable, with Outstanding Performance
From the very beginning of the design, QC Solar's junction boxes have regarded safety and stability as top priorities. The fool-proof and anti-fault designs of the upper cover and diodes effectively prevent misoperations during the installation process, ensuring the stable operation of the system. To perfectly match the performance parameters of perovskite photovoltaic modules, module and axial diodes with rated current meeting 10A and reverse withstand voltage greater than 1000V are selected. The products have obtained both TUV and UL certifications, facilitating global access. This provides a powerful guarantee for the efficient and safe operation of the system.

Global Layout, Quality Commitment
Relying on leading process technologies and forward-looking design concepts, our products not only inject new vitality into the solar market but also achieve stable production on a global scale. We have established a complete sales and service network in multiple production bases and Country, ensuring that we can meet market demands in a timeIy manner and provide global users with high-quality solar solutions and technical support.
