Power after 30 years
  • Efficiency of 22.9% matches the TOPCon 700-750W median
  • Power density of 228.6 W/m² matches the TOPCon 700-750W median
  • At -0.29%/°C, hot weather performance is typical for TOPCon 700-750W panels
  • At 36.7 kg, this panel is 1.3 kg lighter than TOPCon 700-750W median (38.0 kg) - easier handling during installation
  • Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof

Show series description

The DAH DHN-66Y18/DG photovoltaic panel series revolutionizes the approach to efficiency through the use of unique, patented Full Screen technology. The lack of a protruding frame at the edges allows water and sediment to flow off freely, which effectively eliminates the problem of dust and mud accumulation at the module boundaries. This innovative solution directly translates to higher energy yield, reducing power losses caused by dirt by up to 15 percent annually compared to traditional designs. The use of advanced N-type TOPCon cells ensures not only higher base efficiency but also significantly better performance in diffused light conditions and lower degradation over time. The robust Bifacial Dual Glass construction enables double-sided energy generation while maintaining the highest resistance to harsh weather conditions, making these modules an ideal choice for modern home installations and professional photovoltaic farms. Thanks to the minimalist front frameless design, the system requires significantly less frequent maintenance, which is a key advantage for investors who value time and money savings. Choosing this series is an investment in technology that realistically solves the problem of edge sediments, offering stable and high power production where standard solutions lose their efficiency.
