Show series description

The TCL Zhonghuan G11RA-72P series introduces a new level of quality to the large-scale photovoltaics sector, basing its design on breakthrough G11 format silicon wafers. The use of such a large cell surface area allows for achieving unprecedented power density, which directly addresses the problem of high installation costs by reducing the number of required mountings and cabling. A key differentiator of the series is the advanced N-type TOPCon cell technology, which offers outstanding resistance to the LID degradation phenomenon and better efficiency in the diffuse light spectrum. These modules were designed for the most demanding industrial investments and solar farms, where the priority is achieving the lowest cost of energy (LCOE) throughout the entire power plant lifecycle. Compared to standard solutions, the G11RA-72P series is characterized by a significantly better temperature coefficient, which minimizes production drops during summer heat. The solid frame construction and high-transmittance tempered glass ensure maximum mechanical resistance to extreme weather events. It is a smart choice for professionals seeking innovation that combines high module performance with the optimization of profitability for large-scale PV projects.
