Sunoyster Systems has presented the PVbondi lightweight glass-glass module, designed for low-load-bearing roofs.
The system reportedly improves rear ventilation, reduces roof load, and enables faster installation while offering high adhesive strength for flat-roof PV applications.
Germany-based solar tracker developer Sunoyster Systems has presented a new lightweight solar module for rooftop applications at the Smarter E event in Munich, Germany, last week.
The PVbondi module features a power output of 450 W and an efficiency of 22.2%. The glass-glass design incorporates 96 monocrystalline solar cells. It measures 1,780 mm × 1,153 mm × 48 mm, keeping it below the two-square-meter threshold. The datasheet lists a weight of approximately 24 kg and a bifaciality of around 80%.
The module is designed for an operating temperature range of -40 C to 85 C, with a temperature coefficient of 0.29%/C. Sunoyster offers a 15-year product warranty and a 30-year performance warranty for the new product. After 30 years, it is expected to retain 87.4% of its initial output.
