Rayzon launches ultra-high-power generation solar modules under L’LIOS Series

Rayzon Solar has introduced its MBB module under the L’LIOS series with mono-PERC modules, glass-to-glass modules, and glass-to-transparent back sheet modules. If we talk about the L’LIOS series mono facial panel, it has some special features. It provides ultra-high-power generation and ultra-high efficiency since it is developed and designed in a world-class manufacturing facility adhering to the certification criteria. Other distinguished features are lower LID/LETID, high compatibility, a lower temperature coefficient, optimised operating temperatures, lower degradation with solar cells sourced from the world’s most well-known solar cell manufacturer, outstanding low light performance, and exceptional PID resistance.
In line with the expansion plan of Rayzon Solar to reach 5 GW of capacity by 2025, Rayzon has installed a 1.2 GW fully automated MBB module production facility at its factory in the outskirts of Surat. The MBB production facility has laser-based cell cutters, tabber-stringer machines with a robotic layup, auto-bussing machines, auto glass loaders, auto back sheet, EVA cutter cum loaders, 3-chamber oil-based laminators, auto-trimming and auto-framing machines, and an automated curing line that possess state-of-the-art production features.
Rayzon’s Multi-busbar (MBB) modules offer several advantages over the polycrystalline modules that have been traditionally used in the DCR landscape. The MBB modules are made using PERC solar cells, which respond to a broader wavelength range of the incident sunlight and can capture more light in the early morning and late evening. Furthermore, PERC cells convert light into electricity more efficiently than traditional poly solar cells. Further, the PERC cells are mono-crystalline cells. They have a lower temperature coefficient, so they are more tolerant to higher operating temperatures and will generate more power than poly cells when operated in hot regions (like Rajasthan). The MBB modules are made using half-cut solar cells so that the cell current is lower than the module current, which helps to reduce the resistive loss in the cell interconnects (as resistive loss is proportional to the square of the current).
“Multi-busbar modules” or “multi-wire modules” are the natural next evolution of the cell-stringing technology, which supports the constant increase in a PV module’s peak power; the same situation that we saw in the past years with the current main industrial technology, starting from the initial 2 BB up to the 5 BB of today. Achieving the highest production capacity and getting the perfect outcome in the finished product is a challenging task, and of course, it requires technological improvement. “Every technological advancement that we implement in production is the result of our R&D team’s efforts to identify the most advantageous and cost-effective solution,” Hardik Kothiya, Director – RAYZON SOLAR PVT LTD, explained during the discussion.
The cell bars are smaller in the MBB cells, while their number is larger (10 or more). Smaller cell bars increase the available silicon area exposed to sunlight. Also, the higher number of busbars reduces the distance between these busbars, thereby reducing the resistance to electron flow and enabling better capture of the electrons generated from sunlight. The additional advantage of the MBB modules is that they are more shade-tolerant, resulting in fewer chances of hot spots under partial shading conditions. Also, these panels are more tolerant to micro-cracks, so cracks generated during field operation will generally not affect the power output of MBB modules as much as in poly modules. Thus, the overall efficiency and reliability of the MBB modules are much higher than those of poly modules, which will translate into higher energy generation over the lifespan of the modules.
