In the quest for a sustainable future, Trinasolar's 210 Vertex Super Factories stand as a beacon of innovation in the photovoltaic industry. These cutting-edge facilities are not just buildings; they are a glimpse into the future of solar energy, where advanced technology meets unmatched efficiency. These state-of-the-art factories are changing the game in solar module manufacturing, revolutionizing how we harness the power of the sun.

But what sets Trinasolar's 210 Vertex Super Factories apart? Let's dive deeper to explore how they are reshaping the future of solar energy.

The 210 Vertex Super Factory: Where Innovation Meets Efficiency

Trinasolar's 210 Vertex Super Factories marked a significant milestone in the photovoltaic industry when the first three facilities (located in Zhejiang province, as well as Suqian and Yancheng in Jiangsu province, China) completed construction in 2020. These factories are the epicenter of Trinasolar's smart manufacturing of ultra-high power solar modules, leveraging cutting-edge technologies tailored for 210mm-based modules with unparalleled efficiency and precision.

Since then, we have expanded our network of 210 Vertex Super Factories across China and globally. These hubs represent the culmination of years of research and development, making them some of the most advanced photovoltaic manufacturing facilities worldwide. The strategic locations and advanced capabilities of these factories ensure that our customers receive high-quality solar modules, regardless of where they are in the world.

Trinasolar's 210 Vertex Super Factories harness full automation to achieve unprecedented efficiency, precision, and consistency in every stage of solar module production. This level of automation reduces labor requirements by about 25% per gigawatt (GW) compared to previous workshops, paving the way for the efficient production of next-generation solar technology. These benefits carry over to end users through lower costs and shorter delivery timelines, driven by lower production costs and faster manufacturing.

Manufacturing automation is but one piece of the larger picture. To produce cutting-edge solar energy modules, we employ advanced manufacturing techniques developed over decades of research. In 2022, two of our Super Factories in Suqian and Yancheng were recognized as Smart Manufacturing Demonstration Factories by China's Department of Industry and Information Technology of Jiangsu Province, demonstrating our leadership in automation, digitalization, and intelligent manufacturing in the PV industry. These recognitions reflect our commitment to producing high-efficiency solar modules that maximize energy output and durability for customers.

From Silicon to Modules: The Cutting-Edge Production Process at Trinasolar

Step inside the Vertex Super Factory, and you'll find a world of superintelligence and automation. Standing at the forefront is the 210+N 700W+ Super Factory, the latest addition to Trinasolar's array of Super Factories.

Trinasolar's 210+N 700W+ Super Factory is a beacon of advanced solar technology. From the initial silicon crystals to the final solar modules, every step is designed for maximum precision and performance.

Starting Strong: Ensuring Quality from Crystal to Wafer

Precision is crucial because imperfections introduced at any part of the manufacturing process can cause defects, affecting the long-term performance of solar modules. Trinasolar builds quality into each part of the manufacturing process, ensuring precision from the very start.

The manufacturing process begins with silicon crystals, the base materials for all solar modules. The silicon crystals are meticulously pulled and solidified into cylindrical rods to remove any impurities, ensuring a defect-free foundation for solar cells. The silicon rods are then sliced into thin segments, coded with laser precision, and precisely diced into ultra-thin 210 silicon wafers just 30 micrometers (μm) wide. This level of precision ensures consistency and quality across all wafers.

Precision in Automation: The Journey from Wafer to Module

These wafers then undergo a series of automated treatments to form 210 silicon cells:

• Alkaline texturing: Reduces light reflection, which increases light absorption and enhances the overall energy yield.


• Diffusion: Enhances electrical conductivity, ensuring efficient energy flow.


• Atomic layer deposition: Adds, with atomic precision, a layer that increases resistance to environmental erosion, enhancing durability.


• Printing: Integrates electrodes that ensure electrical conduction.


• Sintering: Improves electrical contact between electrodes and the silicon layer, improving energy yield.

210 silicon wafers undergo a series of automated processes to enhance electrical yield and resistance to environmental degradation.

Afterwards, the processed cells are cut using non-destructive cutting techniques, welded into strings, and assembled into the module layout. They are then securely integrated to become one module through overlap welding. With Trinasolar's cutting-edge welding machines, welding is completed at 4,000 pieces per hour, setting an industry-wide speed record. This rapid production capability ensures timely delivery of products to meet market demand, providing you with quicker access to the latest solar technology.

From crystal to module, Trinasolar's 210+N 700W+ Super Factory covers the entire manufacturing process of a solar module.

Rigorous Quality Assurance for Optimal Performance  

As each silicon wafer undergoes meticulous processing, the final stages of production are equally critical. To ensure that every module meets the highest standards, Trinasolar implements rigorous quality assurance protocols.

Post-production, the modules undergo rigorous electroluminescence (EL) testing to identify any micro-cracks or defects that might not be visible to the naked eye, ensuring that every module meets Trinasolar's stringent quality standards before it reaches you. They are then automatically framed before undergoing a meticulous visual inspection by both artificial intelligence and trained professionals to guarantee compliance with stringent quality standards.

Rigorous testing guarantees top performance and durability.

Through the intricate implementation of automation and technologies, the 210+N 700W+ Super Factories significantly improve inspection efficiency and product yield. For our partners, this means receiving solar panels that are not only highly efficient but also built to last, offering peace of mind and a solid return on investment.
