Show series description

The GKA-PRO solar panel series is an advanced solution based on N-type TOPCon technology, which redefines efficiency standards in challenging lighting conditions. Thanks to the use of N-type cells, these modules are characterized by significantly lower light-induced degradation and a better temperature coefficient, which translates into stable energy production even during hot days. The bifacial design used in this series allows for additional energy yield from reflected light reaching the back of the module, making them an ideal choice for ground-mounted installations and commercial carports. An innovative approach to production processes eliminates the PID effect problem, ensuring maximum system lifespan for decades. The GKA-PRO series solves the problem of limited installation space by offering high power density per square meter, allowing for a faster return on investment while maintaining the highest safety standards. Compared to the competition, these panels stand out with an excellent balance between advanced technology and mechanical reliability, confirmed by high resistance to loads from snow and wind. This is an uncompromising choice for investors seeking modern components for building efficient and durable solar power plants that maintain their technical parameters over a long-term horizon.
