Solid all-round for its segment
The Suntech Ultra T 1.0 series is a photovoltaic module lineup engineered for investors seeking maximum energy yield from limited installation space. The panels use N-type TOPCon half-cut cells, delivering higher conversion efficiency and reduced power losses from shading effects and resistance. Thanks to multi busbar technology, current collection and optical utilization across the cell surface are improved, resulting in more stable energy output across varying irradiance conditions. Ultra T 1.0 modules are bifacial, double-glass panels, generating additional energy from reflected light hitting the rear side - a solution particularly attractive for utility-scale solar farms and installations on bright, reflective surfaces, where it meaningfully lowers the project's LCOE. The series also stands out for its very low power degradation, achieved through zero LID and reduced LeTID and PID effects, ensuring stable energy production over decades. The reinforced aluminum frame construction provides high resistance to mechanical loads from snow and wind, making this series a solid choice for both rooftop and ground-mounted installations in demanding climate conditions.
Ranking
Signals from the data
Utility-scale, commercial and shaded-installations.
- 23.3% module efficiency - 0.9pp better than the TOPCon 650-700W median of 22.4%
- Power density of 232.5 W/m² packs 8.8 W/m² more into the same footprint vs TOPCon 650-700W median (223.7 W/m²)
- Temperature coefficient of -0.29%/°C matches the TOPCon 650-700W median
- 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces
- Ranked #1057 out of 14129 panels for efficiency in the database
