10 questions about Trina Solar's Vertex modules
Q: What is the recommended Vertex model?
A: Based on the 210mm Vertex technology platform, Trina Solar has developed 400W, 500W, 550W, 600W and 670W options. The 400W and 500W modules are those specifically designed for distributed application scenarios. . The former is also known as Vertex S and described as "Small in Size, Big in Power". There are three types of Vertex S 400W modules: with silver frame, black frame and full black. There are two types of 500W Vertex modules: single glass and double sided glass.
Q: What are the specifications of the Vertex 400W / 500W series modules in terms of size, weight and efficiency?
A: The table below shows the specific performance parameters of each and their comparison with conventional 166mm modules. It is clear that Vertex modules are more efficient. Module current is best optimized with main flux inverters.
Q: Why is the Vertex module more efficient than the conventional 166mm module?
A: The actual efficiency of P-type PERC cells is basically the same. The conventional 166mm module uses monocrystalline cells with rounded corners, while the 210mm module from Trina Solar uses square cells with high-density interconnect technology, which means that the gap between the cells is narrower. In this way, it is possible to achieve greater energy production within the same area.
Q: Does a 210mm wide wafer necessarily mean a large module?
A: This is a misconception. Large silicon wafers do not automatically mean large or high-current modules. Trina Solar has separately developed the 210mm Vertex 400W / 500W series for application in distributed scenarios. These two options are based on advanced technologies such as high-density cell interconnection, which allows them to be similar in size to conventional 166-60P (375W) and 166-72P (455W) modules, but with higher power. Vertex 400W and 500W modules achieve an excellent balance in terms of module size, weight, efficiency and ease of on-site installation
Q: The high current modules of the Vertex 400W / 500W series? Can conventional inverters be compatible with them?
A: No, they are not high current modules. Trina Solar adopts a tri-cut design, dividing 210mm cells into three, which effectively reduces the current to the maximum power point. . The current parameters of the two modules are detailed in the following table.
The table above clearly shows that the 210mm Vertex 400W and 500W series modules are both much lower in current than the maximum allowable input value of conventional inverters. Therefore, there is no need to worry about fit or compatibility issues, and no updates or changes are required. Both modules are fully compatible with all traditional inverters.
Q: Can the 210mm Vertex 400W / 500W series modules reduce logistics and storage costs compared to conventional 166mm modules?
A: The table below shows the logistics aspect comparison of 210mm Vertex 400 / 500W series modules and conventional 166 modules. It is clear that the cost of logistics and storage of 210mm Vertex modules is significantly lower. This provides installers and distributors with significant reductions in relocation and storage costs, reducing the cost of renting and relocating the crane from ground to roof, saving time and improving efficiency.
D: Vertex S modules use a 30mm frame. Is there any risk with the carrying capacity? Is the mechanical load performance of a 30mm frame lower than that of a 35mm frame?
A: The compatibility of the mechanical load of the module depends mainly on the material and design of the frame, rather than just the dimensions of the frame. In fact, the optimized 30mm frame design of the Vertex S module increases the thickness of the frame and expands the frame cavity to distribute the high strength bearing material, which means that the mechanical loading performance of the module is greatly improved. The maximum load on the front of a Vertex S module can reach 6000Pa and the maximum load on the rear 4000Pa, which is much higher than the respective 5400Pa and 2400Pa with conventional modules.
Q: Are there any issues with rack installation for 210mm Vertex 400W / 500W Series Modules? Does the 500W series module need 3 beams and 6 briquettes?
A: The superior mechanical load performance of the two modules has already been mentioned and there are no further installation difficulties than conventional modules. They are very easy to install. Therefore, when special mounting methods are used, such as a four-point long edge method or a four-point short edge method, a higher load can be provided, and the mounting methods are more varied and convenient. The relevant mounting methods have already been tested in Trina Solar's laboratory and in practice a more flexible design can be achieved, as described in the Trina installation manual. In general, it is not necessary to use 3 beams and 6 briquettes for the 500W series modules. The need for additional clamps to ensure the modules' ability to withstand the load can be determined based on local weather conditions.
Q: What are the advantages of Vertex 400W / 500W 210mm series modules over conventional 166 modules in terms of BOS cost?
A: As distributed photovoltaic power generation gradually enters the subsidized era, lower BOS costs and more power generation are needed to ensure the same returns. Vertex 400W / 500W 210mm series modules have better module efficiency than conventional 166mm modules, which can significantly increase power by 25-50W and achieve greater installed capacity on the same roof area. Increasing installed capacity can significantly reduce the cost per watt of trackers, cables, network connected cabinets (boxes) and installation accessories and achieve lower BOS costs. According to calculations by numerous design institutes and installers based on real-life cases, the reduction in BOS costs provided by the 210mm Vertex modules can reach more than 1 US cent per watt.
Q: How should the core value of 210mm Vertex 400W / 500W series modules be summarized?
A: The core values āācan be summarized as follows:
Small size, big power: Compared with similar size modules, the power can be greatly increased by 30 ~ 60W.
More installed capacity, more power generation: more installed capacity and power generation are achieved on the same roof.
Lower Costs, Higher Returns: Higher project returns are achieved with lower system costs.
Powerful technology: Based on the Trina Solar Vertex technology platform, many industry leading technologies have been and will be developed.
