  • At 23.0% efficiency, this panel is on par with typical Back Contact 450-500W modules
  • Power density of 230.3 W/m² is 4.9 W/m² below Back Contact 450-500W median (235.2 W/m²) - needs more roof space
  • Temperature coefficient of -0.26%/°C matches the Back Contact 450-500W median
  • In the top 12% for efficiency among all Back Contact panels

Show series description

The Gokin GK-3-54HGb solar panel series is an advanced solution based on N-type TOPCon technology, which redefines performance standards in difficult lighting conditions. Thanks to the bifacial glass-glass construction, these modules not only exhibit increased mechanical resistance but, above all, generate additional energy yield from reflected radiation. The problem of rapid power degradation and performance drops at high temperatures is eliminated here through low temperature coefficients and better stability of N-type cells. The use of a bifacial structure makes these panels an ideal choice for ground-mounted installations and modern carports, where every additional kilowatt of energy is crucial for the profitability of the investment. Gokin GK-3-54HGb stands out from the competition with exceptional Dual Glass durability, which significantly extends the system's lifespan and protects the cells against micro-cracks or chemical corrosion. This product is aimed at investors looking for maximum reliability and a quick return on capital in demanding commercial and domestic projects. The aesthetic finish and high power density allow for the efficient use of limited roof space while maintaining the highest technical parameters for decades of operation.
