Photovoltaic panel - Suntech 445W B Grade, 144-CELL Half-cut Monocrystalline

IMPORTANT: ALL PANELS ARE SOLD IN PIECES (31 pcs.)!!!

Suntech Ultra S is a high-quality monofacial half-cell solar panel designed for maximum efficiency, long service life and durability in harsh outdoor conditions. This series provides excellent low-light performance, low operating temperature and reduced current distribution losses - the result of advanced manufacturing technology and current sorting. Ultra S is suitable for rooftop and ground-mounted PV installations - for both residential and commercial projects.

Main advantages

• High conversion efficiency. Thanks to the innovative cell architecture and half-cell technology, Ultra S panels offer a module efficiency of up to around 21.1% (for the higher variants), which increases the energy yield per square meter.
• Excellent low-light performance. Current sorting technology reduces losses during cloudy weather, dawn and dusk, which increases actual energy yield in different weather conditions.
• Wide temperature range. The panels operate effectively at temperatures from -40 °C to +85 °C, with favorable temperature coefficients for power and voltage, which ensures stable operation under high loads.
• Mechanical resistance. With high wind and snow resistance values (up to 3800 Pa/5400 Pa in some variants), the panels are suitable for installation on roofs and outdoor spaces even in harsh weather conditions.
• Long life and warranty. The manufacturer provides a 12-year product warranty and a significant power output guarantee (e.g. 10 years – 93.05%, 25 years – 84.8%), ensuring long-term reliability and profitability.
