Middle of its segment, modest efficiency
The Suntech Ultra V series redefines performance standards through the use of large-scale M10 silicon wafers and advanced Half-Cut technology. This design effectively solves the problem of power losses resulting from internal resistance, which translates into higher yields even in difficult lighting conditions. A key differentiator is the innovative high-density cell interconnect, which minimizes gaps between them, maximizing the module's active area without drastically increasing its dimensions. Thanks to the use of Multi-Busbar technology, the panels show less susceptibility to micro-cracks and conduct current more efficiently. This series was designed for commercial investments and photovoltaic farms, where low LCOE cost of energy and operational stability at high temperatures are of key importance. Solid construction and optimized mechanical stress distribution make the Ultra V outperform the competition in terms of resistance to extreme weather events. Choosing this line is a guarantee of safety for projects requiring the highest reliability and fast return on investment, while maintaining excellent aesthetics.

Bottom 1% of the TOPCon 500-550 W segment, against a median of 22.74%. Ranked 10,842nd in the whole database.
Bottom 2% of the TOPCon 500-550 W segment, against a median of 227.4. Ranked 10,842nd in the whole database.
Bottom 3% of the TOPCon 500-550 W segment, against a median of 52.4. Ranked 12,370th in the whole database.
- Efficiency of 20.7% is 2.0pp below the TOPCon 500-550W median (22.7%)
- At 207.1 W/m², this panel generates 20.3 W/m² less per unit area than TOPCon 500-550W median (227.4 W/m²)
- -0.34%/°C temperature coefficient - 0.05pp worse than TOPCon 500-550W median (-0.29%/°C), expect higher hot weather losses
- At 32.0 kg (5.0 kg above TOPCon 500-550W median of 27.0 kg), requires checking roof load capacity
- Bifacial design (70% factor) captures reflected light - adds 4-10% yield on ground-mount or white roof
