As the global energy landscape undergoes a seismic shift toward carbon neutrality, HJT (Heterojunction Technology) solar panels have emerged as the vanguard of high-efficiency photovoltaic solutions. Unlike traditional PERC (Passivated Emitter and Rear Cell) technology, HJT combines the best features of crystalline silicon and amorphous silicon thin-film technologies. This unique structure results in higher conversion efficiencies, superior temperature coefficients, and exceptional bifaciality. Today, as a leading China OEM HJT solar panel manufacturer, we are at the center of this revolution, providing the global market with modules that redefine performance.
The global commercial and industrial (C&I) sectors are increasingly demanding high-power outputs to maximize the return on investment (ROI) for solar installations. In regions like Europe, North America, and Australia, land and labor costs are high, making the high energy density of HJT panels—often exceeding 700W per module—a critical factor in reducing the Levelized Cost of Energy (LCOE). Our factory specializes in the mass production of N-type HJT modules, leveraging state-of-the-art automation and AI-driven quality control to ensure every panel meets international Tier 1 standards.
HJT cells consistently push the limits of PV efficiency.
-0.24%/°C ensures better performance in hot climates.
Maximize energy gain from both sides of the panel.
Our HJT 2.0 technology utilizes a streamlined manufacturing process that reduces thermal stress on the silicon wafers. This results in a product with significantly lower LID (Light Induced Degradation) and LeTID (Light and elevated Temperature Induced Degradation) than standard p-type panels. For global industrial procurement, this means a reliable 30-year power warranty with linear degradation as low as 0.375% per year.
As a dedicated solar panel factory, we offer extensive OEM and ODM services. Whether you are a local distributor in Brazil looking for cost-effective 550W modules or a utility project manager in the Middle East requiring 750W high-power bifacial modules, our production lines are optimized to meet your specific technical requirements.
The solar industry is currently witnessing a massive transition from "P-type" to "N-type" silicon. Within the N-type category, HJT is gaining significant ground due to its simplified four-step production process, which offers a higher theoretical efficiency ceiling than TOPCon. Major global enterprises are now prioritizing HJT in their procurement strategies for three primary reasons: longevity, power density, and aesthetics (the sleek black appearance of HJT panels is ideal for residential BIPV applications).
Localization and Application Scenarios:
1. Utility-Scale Farms: In deserts and high-albedo environments (like snow or white sand), the 90%+ bifaciality of our HJT panels provides up to 30% more power generation compared to monofacial panels.
2. Floating Solar: HJT modules are naturally resistant to PID (Potential Induced Degradation), making them the perfect choice for high-humidity floating solar projects on reservoirs.
3. Cold Climates: In Northern Europe and Canada, the excellent low-light performance of HJT ensures power generation even during short winter days.
Why choose a China OEM HJT solar manufacturer? China currently hosts the world's most robust photovoltaic supply chain. From high-purity polysilicon to specialized silver-coated copper pastes for HJT electrodes, everything is sourced locally. This vertical integration allows us to provide premium N-type technology at prices that were previously only possible for PERC modules.
Our factory's R&D team is constantly iterating on "Zero-Busbar" (0BB) technology and ultra-thin silicon wafers (down to 120μm), which further reduces costs and improves module flexibility. This technical agility is why global brands partner with us for their OEM needs, ensuring they stay ahead of the technology curve without investing billions in their own manufacturing infrastructure.
We offer a wide range of products for residential, commercial and industrial applications, and utility-scale. We are committed to utilizing the most advanced technologies and maintaining the highest quality standards in the design, manufacturing, and delivery of our solar panels.

Experience in the solar industry since 2005.
Current capacity expanding to 10GW by 2026.
Supplying global markets with high-quality PV.
Wing stands for a well-established Tier 1 manufacturer by BloombergNEF. We are a stable company producing high-quality solar panels in large volumes and with strong warranties. Since its establishment in 2005, Wing has maintained a steady growth trajectory, today employing more than 500 people in China and Europe. Since 2023 Wing Solar is a public company.
When selecting a solar panel factory in China, buyers must look beyond price. Quality assurance (QA) protocols, such as triple EL (Electroluminescence) testing and salt-mist corrosion resistance, are non-negotiable for panels intended to last 30 years. Our factory integrates Industry 4.0 standards, where AI algorithms analyze EL images in real-time to detect micro-cracks invisible to the human eye. This level of precision is why our HJT modules are trusted for mega-utility projects across the APAC and EMEA regions.
Furthermore, sustainability is at the heart of our operations. The production of HJT cells requires lower temperatures (under 200°C) compared to PERC or TOPCon (over 800°C), significantly reducing the carbon footprint of the manufacturing process itself. For corporate clients with strict ESG (Environmental, Social, and Governance) targets, our HJT panels offer the "greenest" way to generate green energy.
In conclusion, the future of solar is N-type, and the peak of N-type is HJT. As a leading manufacturer, we invite global distributors, EPC contractors, and project developers to explore the potential of our HJT modules. From 100W flexible panels for mobile applications to 800W bifacial monsters for the world's largest solar arrays, we have the manufacturing capacity and technical expertise to power your project into the next decade.
