Photovoltaic panels from the GCL NT12/66GDF series redefine performance standards thanks to the use of innovative N-type TOPCon cells, which effectively eliminate negative power degradation phenomena over time. The construction based on bifacial double-glass technology ensures that these modules not only generate energy from direct radiation but also effectively utilize light reflected from the ground, significantly increasing investment profitability in challenging lighting conditions. The use of large silicon wafers in the Large-format 210mm format allows for the construction of higher-power systems with fewer mounting components, which realistically reduces the cost of the entire installation. This series is primarily designed for large-scale farms and major commercial projects, where durability and resistance to external factors are key. What distinguishes these panels from the competition is an excellent temperature coefficient and enhanced protection against micro-cracks through the use of double tempered glass. By choosing this solution, investors receive a guarantee of stable energy production for decades, while ensuring the highest level of fire and mechanical safety, placing this series at the technological forefront of the industry.
