Notes from the database
  • Efficiency of 15.5% is 6.3pp below the database median (21.8%)
  • Power density of 155.1 W/m² is 63.0 W/m² below database median (218.1 W/m²) - needs more roof space
  • Temperature coefficient of -0.39%/°C is 0.09pp worse than database median (-0.30%/°C) - higher losses in summer heat
  • At 5.7 kg, this panel is 20.8 kg lighter than database median (26.5 kg) - easier handling during installation
  • #13717 for efficiency, #13579 for temperature performance out of 14005 panels
