Description
575W Tongwei Solar N-Type Bifacial | TWMND-72HD
MAIN FEATURES
N-Type Half-Cell Technology: the 575W Tongwei TWMND-72HD solar panel incorporates N-Type monocrystalline half-cut cells, a configuration designed to reduce electrical losses and maintain stable power generation throughout the module’s service life.
Bifacial Dual-Glass Design: its construction allows the module to harness both the solar radiation received on the front side and the reflected radiation reaching the rear side. The bifacial gain will depend on the albedo, installation height and site characteristics.
High Power and Efficiency: with a nominal power output of 575W and a module efficiency of 22.3%, this panel optimises the available surface area and reduces the number of modules required in commercial and industrial photovoltaic installations and utility-scale projects.
Low Power Degradation: the manufacturer specifies a maximum degradation of 1% during the first year and 0.4% per year from the second to the thirtieth year, maintaining at least 87.4% of the original power output at the end of year 30.
Mechanical Strength: the module is designed to withstand loads of up to 5,400 Pa on the front side and 2,400 Pa on the rear side, providing a robust construction suitable for demanding environmental conditions.
