Show series description

GCL NT10/72GDF photovoltaic panels are an advanced solution based on N-type TOPCon technology, setting new efficiency standards in large-scale installations. Thanks to the use of N-type cells, these modules are characterized by near-zero light-induced degradation and excellent efficiency in low sunlight. The bifacial dual-glass construction allows for the effective use of light reflected from the ground, which significantly increases total energy generation compared to standard, single-sided counterparts. The use of large silicon wafers translates into system cost optimization, which is crucial for investors seeking a maximum return on investment. This series effectively eliminates the problem of rapid power loss over time, offering exceptional parameter stability over decades of operation. It is a product dedicated primarily to professional photovoltaic farms and large commercial facilities, where every kilowatt-hour of yield and durability in variable weather conditions count. What distinguishes them from the competition is the precise combination of high power density with a low temperature coefficient, which ensures that the modules work stably even during hot days. By choosing the GCL NT10/72GDF series, you gain investment certainty based on innovations that realistically shorten the payback period through higher production in a real-world operating environment.
