The GCL-NT12/66GDF series features advanced modules based on N-type TOPCon technology that set new performance standards in variable weather conditions. The use of bifacial cells enables efficient energy generation from both sides of the panel, significantly increasing total energy yield, especially in installations on surfaces with high light reflectance. The robust glass-glass construction guarantees exceptional resistance to potential-induced degradation (PID) and protects cells from micro-cracks, which translates into long-term financial stability for the investment. Thanks to a low temperature coefficient, these panels operate with high efficiency even on hot days, effectively minimizing power losses. They solve the key problem of limited installation space by offering impressive energy density per square meter. This product is primarily dedicated to professional photovoltaic farms and large commercial systems where the lowest levelized cost of energy (LCOE) is the priority. What sets them apart from competing solutions is high efficiency in low sunlight and excellent sealing, which protects the system against corrosion and moisture. Choosing this series means maximizing gains from bifaciality while maintaining top-class fire safety and full reliability in harsh operating environments.
