Show series description

Tongwei TWMNH-48HW Series are monofacial dual-glass modules featuring a black frame, engineered for stable performance in real rooftop and commercial installations – where durability, aesthetics, and predictable yield matter. The application of N-type cells in a half-cell configuration helps minimize module losses and improves performance under partial shading, effectively simplifying the design of complex roof geometry systems.

The series' key feature is its focus on reliability: the glass-to-glass construction enhances resistance to atmospheric conditions and long-term loads, while Tongwei’s production technologies, such as 0BB (908 Technology) with ultra-multiple connections, boost resistance to micro-cracks and material fatigue. Furthermore, TPE and precise screen printing are optimized for better current conduction and repeatable quality.

This is an excellent choice for investors seeking to combine high manufacturing standards with easy integration into modern PV systems – from residential homes to C&I projects.

Panels from the same series differ mainly in power output while having identical dimensions. Learn why →
