-0.370 %/°C temperature coefficient

Bottom 6% of the 300-500 W band, against a median of -0.300. Ranked 13,081st in the whole database.

Notes from the database
  • At 204.8 W/m², this panel generates 13.3 W/m² less per unit area than database median (218.1 W/m²)
  • Temperature coefficient of -0.37%/°C is 0.07pp worse than database median (-0.30%/°C) - higher losses in summer heat
  • Weight of 21.4 kg (5.1 kg below database median of 26.5 kg) allows easier transport and roof mounting
  • Ranked #13999 out of 14005 panels for efficiency in the database
