Solar Module Tongwei TWMNH-66HD605W

The Tongwei TWMNH-66HD605W uses 132 monocrystalline N-Type Half-Cut cells. N-Type silicon shows less light-induced degradation than classic P-Type cells, so performance remains more stable over the years. The halved cells reduce internal resistance losses and improve behavior in partial shading.

A bifacial module converts light on both sides into electricity. If light—reflected from a bright surface, snow, or gravel—hits the rear side, it generates additional yield. This requires elevated mounting with a distance from the ground so that the rear side is freely exposed to light.

With average solar irradiation, a 605 Wp module in Austria delivers around 580 to 660 kWh per year, and potentially more with the bifacial rear side and suitable ground. At an electricity price of 25 ct/kWh, this corresponds to savings of approximately 145 to 165 Euros per module per year.

For a typical annual consumption of 4500 to 5500 kWh, about 8 to 12 of these 605 Wp modules are suitable, resulting in approximately 4.8 to 7.3 kWp. The exact number depends on roof orientation, tilt, shading, and the desired self-consumption rate.

Yes. The module is designed for a surface load of up to 5.4 kPa and is certified according to IEC 61215 and IEC 61730, which covers wind and snow loads as well as mechanical stress tests. The hardened ARC glass and aluminum frame are therefore also suitable for regions with heavy snowfall.

Tongwei is a global manufacturer in the photovoltaic value chain and is one of the largest producers of solar cells and modules. The company manufactures high-quality monocrystalline modules for residential and commercial installations.
