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. ## Notable figures - Efficiency of 23.2% matches the \*\*TOPCon 600-650W\*\* median - Power density of 232.3 W/m² packs 4.6 W/m² more into the same footprint vs \*\*TOPCon 600-650W\*\* median (227.7 W/m²) - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 600-650W\*\* median - At 31.5 kg, this panel is 1.3 kg lighter than \*\*TOPCon 600-650W\*\* median (32.8 kg) - easier handling during installation - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface ## Questions ### 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. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/STP580-600S-C72-Nsh-9a725436216c.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +50 W, lighter, +2.0 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +45 W, lighter, +1.8 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -40 W, lighter, +1.6 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +40 W, lighter, +1.6 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -45 W, lighter, +1.4 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +35 W, lighter, +1.4 pp | | [Suntech STP530S-C72/Pmh+](https://comparepv.com/panel/suntech-stp530s-c72-pmh) | 530 W | -70 W, hotter, -2.7 pp | | [Suntech STP535S-C72/Pmh+](https://comparepv.com/panel/suntech-stp535s-c72-pmh) | 535 W | -65 W, hotter, -2.5 pp | | [Suntech STP540S-C72/Pmh+](https://comparepv.com/panel/suntech-stp540s-c72-pmh) | 540 W | -60 W, hotter, -2.3 pp | | [Suntech STP545S-C72/Pmh+](https://comparepv.com/panel/suntech-stp545s-c72-pmh) | 545 W | -55 W, hotter, -2.1 pp | | [Suntech STP545S-C72/Nmh+](https://comparepv.com/panel/wuxi-suntech-power-co-ltd-stp545s-c72-nmh) | 545 W | -55 W, hotter, -2.1 pp | | [Suntech STP550S-C72/Pmh+](https://comparepv.com/panel/suntech-stp550s-c72-pmh) | 550 W | -50 W, hotter, -1.9 pp | | [Suntech STP550S-C72/Nmh+](https://comparepv.com/panel/wuxi-suntech-power-co-ltd-stp550s-c72-nmh) | 550 W | -50 W, hotter, -1.9 pp | | [Suntech STP555S-C72/Pmh+](https://comparepv.com/panel/suntech-stp555s-c72-pmh) | 555 W | -45 W, hotter, -1.7 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +30 W, cooler, +1.2 pp | --- Source: https://comparepv.com/panel/suntech-stp600s-c72-nsh Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
