Technology and certificates


Our modules show high energy yield in low as well as in high irradiation areas. High kWh/kWp performance is obtained through:

  • High shunt resistance for improved performance at low irradiation and low series resistance for improved performance at high irradiation
  • Pre-sorting according to PMPP and IMPP minimizing module mismatch losses
  • EVA foil with very low yellowing index (due to degradation processes EVA foil can gradually turn from transparent to yellow colour reducing the amount of incident light)
  • High EVA gel content contributes to outstanding long-term performance
  • Whole spectrum highly transparent glass, produced by specialized company
  • High quality cells with narrow electrical sorting, minimal interconnection losses and uniform colour appearance
  • Low reflection, high transparency, ornamented and tempered solar glass certified to be used even near airfields
  • Module sorting on average nominal power
