Solar Panels

  • Solar modules are designed in Consistent with IEC 61215 Standards
  • Manufactured with proven materials and tested to ensure the stable output power
  • Each 18 and 36 cells series one bypass diode is installed to avoid “hot spot” effect
  • SiN/TiO2 Films deposited on the front surface by PECVD acts as anti-reflection coating and gives a uniform dark blue appearance.
  • Cells are laminated between high transmissivity low – iron 3.2mm tempered glass and sheet of TPT meterial by two sheets of EVA to prevent moisture penetrating into the module.
  • Heavy duty anodized aluminum frame provides high wind resistance and convenient mounting access.
  • Water -proof versatile junction box provides flexibility of connection.
  • Insulation> 100 MW Voltage Standoff: AC2000V DC3000V
  • Wind Bearing > 120Km/h System Voltage 1000V
  • Impact Resistance – Height Impact Test: 225gsteel ball drop from height of 100cm
