Power after 30 years
  • Efficiency of 22.2% is 0.6pp below the N-type 600-650W median (22.8%)
  • Power density of 221.8 W/m² is 5.9 W/m² below N-type 600-650W median (227.7 W/m²) - needs more roof space
  • At -0.30%/°C, hot weather performance is typical for N-type 600-650W panels
  • At 34.3 kg (1.8 kg above N-type 600-650W median of 32.5 kg), requires checking roof load capacity
  • Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface

Show series description

The DAS-DH156NA series are advanced bifacial modules that set efficiency standards through the use of N-type cells in TOPCon technology. This solution effectively eliminates light-induced degradation, guaranteeing investors stable energy production for decades. The bifacial double-glass design allows for the efficient use of reflected radiation, which, combined with high cell efficiency, drastically increases the total energy yield, especially on ground-mounted farms and light-colored roofs. These models are characterized by an exceptionally low temperature coefficient, allowing them to maintain high efficiency even in full sun and at high ambient temperatures. The robust double-glass construction provides enhanced mechanical resistance to harsh weather conditions, protecting the installation from micro-cracks and chemical corrosion. The DAS-DH156NA series is primarily dedicated to large commercial projects and photovoltaic farms, where achieving the lowest LCOE is crucial. It stands out from the competition with its excellent low-light performance and significantly slower power degradation over time, making it one of the most predictable and safe components for modern energy in Poland.
