The Ultra T 1.0 series brings together N-type TOPCon cells and half-cut cell technology, reducing resistive losses and improving performance stability under demanding irradiance conditions. Built as a framed, double-glass bifacial module, it offers strong mechanical rigidity and resistance to snow and wind loads, making it a solid choice for commercial and industrial installations where long-term durability matters most. Thanks to multi busbar technology, the panels make better use of incoming light and collect current more efficiently, boosting the reliability of the entire string. The use of bifacial cells allows the module to capture additional light reflected from the ground, increasing energy yield without expanding the installation footprint - a real advantage wherever roof or ground space is limited. A zero-LID design combined with ultra-low LeTID degradation keeps power loss to a minimum in the early years of operation, while strong PID resistance reduces the risk of losses caused by electrical stress within the module. The Ultra T 1.0 series suits investors looking for a balance between performance, durability, and a lower LCOE across the full lifecycle of the installation.

About the Ultra T 1.0 series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What makes the Suntech Ultra T 1.0 series different from standard PERC panels?
Ultra T 1.0 uses N-type TOPCon half-cut cells, which are more efficient and less prone to degradation than conventional PERC cells. This results in higher conversion efficiency, better performance at high temperatures and in low-light conditions, and a maximum power output of up to 600 Wp - meaning fewer panels are needed to reach the same system capacity.
Are Suntech Ultra T 1.0 panels bifacial, and how much extra energy can they generate?
Yes, Ultra T 1.0 modules are bifacial in a double-glass construction, meaning the rear side also generates power from reflected light. Depending on the ground surface (light gravel, white EPDM roofing, etc.), this can add anywhere from a few to over ten percent more energy yield without increasing the installation footprint, making it especially cost-effective for ground-mount and flat-roof commercial projects.
What warranty comes with the Suntech Ultra T 1.0 series?
The Ultra T 1.0 series is backed by a 15-year product warranty and a 30-year linear power warranty. This means the module is guaranteed to retain a significant share of its rated output even after three decades of operation, backed by Suntech's status as a tier 1 manufacturer headquartered in China with established service and replacement support.
Does the multi busbar technology in the Ultra T 1.0 actually improve performance?
Yes, a denser busbar grid distributes current more evenly across the cell surface and reduces resistive losses, particularly in cases of micro-cracks or partial shading. In practice, this translates into higher and more consistent energy output over the module's lifetime, not just improved figures under standard STC test conditions.
Are Suntech Ultra T 1.0 panels suitable for industrial and utility-scale solar farms?
Yes, the double-glass framed construction provides high structural rigidity and strong resistance to snow and wind loads, which matters on large industrial rooftops and ground-mount installations. The high per-module power output (up to 600 Wp) combined with bifacial technology also lowers the cost per watt, improving the economics of commercial and utility-scale projects.
Do Ultra T 1.0 panels lose power in their first years of operation due to LID?
Not to a meaningful degree - the N-type TOPCon cells used in the Ultra T 1.0 series feature zero LID effect and very low LeTID degradation, resulting in minimal power loss in the first year. High PID resistance further limits losses from potential-induced degradation, allowing the panel to maintain stable performance over many years of service.
