Key takeaways:
Nuuko displayed its TOPCon modules for residential, C&I, and utility-scale applications with power outputs ranging from 430 W to 720 W
The portfolio includes modules based on M10, G12R, and G12 wafer formats, all featuring dual-glass construction and 80±5% bifaciality
All showcased modules carry a 12-year product warranty and a 30-year power performance warranty with 1% first-year degradation and 0.4% annual degradation thereafter
Nuuko Power, an integrated PV and storage solution provider based in China, showcased its range of products at SNEC and Intersolar Europe 2026. The company presented modules for residential, commercial & industrial (C&I), and utility-scale applications from its TOPCon portfolio.
For residential applications in Europe, it promoted a module with a maximum rated power of 430 W and 23% efficiency. The product consists of 108 half-cells, measures 1,722 × 1,134 × 30 mm, and weighs 24.5 kg. Its dimensions are notably under 2 m2, which also makes it suitable for balcony solar applications in Europe.
For utility and C&I applications, the company displayed 3 TOPCon modules. First among these is NKM575-595-144BDM10, which – as the name indicates – uses 144 half-cut cells based on the M10 wafer size and delivers a maximum of 595 W and 23% efficiency. It measures 2,278 × 1,134 × 30 mm. The slightly larger NKM610-635-132BDR12 model, measuring 2,382 × 1,134 × 30 mm, offers a maximum power of 635 W and 23.5% efficiency. This module is based on 132 half-cells of G12R wafer format and weighs 32.5 kg. The largest among all is NKM700-720-132BG12, based on G12 wafers, and delivers a maximum power of 720 W at 23.2% efficiency. The module uses 132 half-cells, measures 2,384 × 1,303 × 33 mm, and weighs 37 kg.
All the modules displayed by Nuuko use a dual-glass construction with 2 mm glass and feature a bifaciality of 80±5%. Similar to other mainstream TOPCon modules, the company also offers power performance warranties with 1% degradation in the first year and 0.4% annual linear degradation until 30 years. All the modules come with a 12-year product warranty.
