Power after 30 years
  • At 23.3% efficiency, this panel is on par with typical TOPCon 700-750W modules
  • At 233.4 W/m² power density, this panel generates 4.6 W/m² more per unit area than TOPCon 700-750W median (228.8 W/m²)
  • Temperature coefficient of -0.29%/°C matches the TOPCon 700-750W median
  • Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof
  • In the top 6% for efficiency among all TOPCon panels
