On August 8th, 2020, a new generation of high-power modules developed by Suntech was officially launched. This is the masterpiece of Suntech to meet the competition of high energy density in modules, marks a new era of ultra-high-performance PV products.

 

Suntech’s new high-power modules equipped with advanced technologies include heterojunction (HJT) modules and Ultra S/V/X series, covering large format silicon wafers of all sizes (166, 182, and 210mm). This series is equipped with mainstream technologies such as half-cut cells, multi-busbar, and bifacial technologies. The output power can reach up to 605W+ and module efficiency can be up to 21.3%. Suntech’s new product development team had the needs of customers in mind: while ensuring maximized reliability of modules, the design of the module structure is user-friendly. Compared with mainstream products of the same specifications in the market, the weight of new products is reduced by more than 1/5, which breaks the technical barriers of ultra-high power and weight reduction, reducing more electricity costs even more (LCOE).

 

Suntech’s heterojunction module: innovation of new HJT technology, ultra-performance and higher efficiency

Suntech’s heterojunction PV module is based on an N-type heterojunction cell design, with a cell conversion efficiency of 24%, 1% more efficient compared with the PERC cell, resulting in a high module conversion efficiency of 21。4% and higher power of 435w。 It is estimated that 158。75mm heterojunction PV modules can be mass-produced in 2020 Q4, and the cell size can be upgraded synchronously later。

 

The Pmax temperature coefficient of Suntech’s heterojunction module is only - 0。268% / , about 40% lower than that of conventional silicon modules。 In high temperature conditions, it can increase power generation by 10-15%, compared with conventional PERC modules。 In addition, Suntech’s heterojunction PV module adopts a bifacial design, with the bifacial ratio up to 90%。 The backside increases the maximum power generation capacity by 30%, which brings with it a higher rate of return on power generation for customers。

 

 

Ultra VCreate the milestone of V, upgrade to high energy density

Based on large format 182mm silicon wafers, Suntech’s Ultra V modules optimize the layout profoundly and adopt high-density cell interconnect technology which shorten the distance between the cells, decrease the invalid power generation area greatly, and improve the energy density of the modules when module efficiency reaches to 21.3%. The combination of mature half-cut cell, multi-busbar technologies, auxiliary materials such as a flexible special ribbon and a highly reflective backsheet can improve the utilization rate of the sunlight, the module power can also be improved significantly, with the highest being 590W.

 

Suntech has a particularly optimized module structure design and owns the exclusive patent. The module weighs 24.4KG, 15% lower than the products of the same specification in the market but with greatly improved mechanical load capacity. When the load reaches +5400 / -2400Pa, the maximum stress of module structure is reduced by 23% compared with conventional structure design, the maximum deformation is reduced by 37%, thus avoiding the risk of micro crack loss and improving the reliability of modules.

 

Suntech Ultra V Series also released a bifacial layout, reducing the weight of the module while ensuring the load capacity. Besides double-glass packaging, it is also compatible with transparent backsheets when needed in project locations, which not only has the features of ultra-high light transmittance and excellent anti-PID performance, but can also effectively reduce the weight by more than 30% compared with the double-glass module. It can also work with the tracing bracket and decrease LCOE effectively.

 

The layout of the Ultra V module can better match the size of the container, so the utilization rate of the container reaches 83.2%. Compared with conventional products with the same power, the Ultra V module reduces transportation cost by 5%, land cost by 5.4%, effectively controls BOS cost, and reduces LCOE by 2.6-2.8%, which can provide customers with higher ROI.

 

 

Ultra XUnlimited imagination of X, discover new possibilities for high-power modules

Suntech Ultra X products adopt large format 210mm silicon wafers and PERC mono cells which increases the light receiving area by 80。5% compared with products of conventional formats。 At the same time, Suntech adopts high-density cell interconnect technology which shortens distance between the cells, decreases the invalid power generation area, and improves the energy density of the module, leading to a module efficiency of up to 21。3%。

 

Suntech’s non-destructive cutting technology made it possible for effectively avoiding the damage of cutting surfaces, realizing the optimal 1/3-cut design, effectively reducing the current loss and the risk of hot spots. By virtue of the multi-busbar technology, the transverse propagation path of the current can be decreased by 50%, resistance loss can be reduced effectively, while realizing the maximum power output and the reliability of the module. While ensuring the reliability of the welding process between cells, Suntech’s upgraded high efficiency ribbon brings more second-time refection of oblique light, which increases the power generation by 1.57% when the highest power exceeds 600W+. 

 

Suntech has a particularly optimized structure design and owns this exclusive patent。 Compared to mainstream products of the same specification, the weight of the module is 26。9KG, reduced by more than 1/5 suiting the transportation standard and reducing the labor cost of installation by 15%。 It also has super mechanical load capacity。 When the load reaches +5400 / -2400Pa, the maximum stress of the module structure is reduced by 23% compared with conventional structure designs。 The maximum deformation is reduced by 37%, thus avoiding the risk of micro crack loss and improving the reliability of modules。

 

Suntech’s innovative user-friendly design ensures that the module size is fully optimized which fully matches the container size while the transportation cost is reduced by 5% compared with the traditional module. Fully compatible with mainstream system designs, Suntech’s Ultra X products match the terminals better and can save the EPC cost by more than 1.2%, save the cost of land by 4% and BOS by 2.7%, ultimately realizing lower LCOE and higher return on investment of customers.

 

 

Ultra SBreak unknown S, Refresh the experience of high efficiency

Suntech Ultra S modules apply large format 166mm silicon wafers, integrated with mature half-cell, multi-busbar technology, whose mass production power can be up to 450W when conversion efficiency can be up to 20.6%. Suntech launched large format modules of 78 cells, whose highest power exceeds 490W. Higher module power can effectively reduce the installation area of the system, which can save the labor cost of installing PV systems and the cost of brackets, maximizing the economic advantage and output power of the PV system. Taking the 120MW project in southern Australia for example, the use of Ultra S 450W modules can decrease LCOE by more than 6% compared with conventional mono PERC half-cell 375W modules.

 

Suntech Ultra S module products have passed IEC certification, and the simultaneous released products of monofacial and bifacial layout have achieved high-performance mass production. Based on different project types and locations, the products of bifacial layout can be equipped with glass or transparent backsheets. By using direct light on the positive side of the module and reflected and scattered light on the back side, the power generation of the module can be greatly increased. According to different ground conditions, the backside generates electricity up to 25%. The 30-year warranty of power of Suntech double-glass modules can fully guarantee the project profits.

 

Furthermore, Suntech has launched such differentiated products such as shingling, slotting and cast mono modules, which provides more options for the technology development of the PV industry.

- Suntech’s cast mono bifacial double glass module adopts 166 right-angle cast mono cells, with high conversion efficiency comparable to conventional mono cells, and a low-cost advantage compared with poly cells. With nine-busbar technology, the module power can reach up to 450W; the backside power generation can be increased by 25% with mature bifacial technology; the tracking bracket can be used to effectively reduce LCOE.

- Suntech’s shingled module uses conducting resin to replace the traditional metal welding tape, which greatly reduces the electrical resistivity。 The non-busbar design reduces the shielding on the cell surface, with a more exquisite appearance; the fine lossless cutting technology reduces the risk of cell cracking, and the module power can reach up to 465W。
