    • Mature quality
      High-end materials such as Aluminum encasing and especially transparent anti-reflection glass as well as more than 30 years producing collectors make up the pedigree of the EURO L20 MQ, placing it at the top in the collector sector.
    • Long collector rows
      Special absorber geometry enables parallel connection of up to 10 solar collectors side by side.
    • Attractive appearance
      Low construction height and narrow gaps between the collectors make for attractive looking flat roof solutions.
    • Certified racking systems
    • The meticulously designed TRIC racking systems ensure enduring fixture. They have been certified by the internationally
    • operating German Technical Inspection AssociationTÜV and can be used for on-roof or free-standing installation.
  • Installing the solar collector EURO L20 MQ AR:

    • Horizontally
    • On-roof and free-standing

    Technical features of the solar collector EURO L20 MQ AR:

    • Collector frame of aluminum, silver-anodized 
    • Smooth streak-free look of the single absorber, achieved by laser welding
    • Highly transparent sunarc® anti-reflection glass increasing heat yield by up to 10%

    Up to 10% more solar yield with sunarc® anti-reflection glass!

    The special nano structure of the inner and outer surface of sunarc® anti-reflection glass reduces reflection considerably, raising the 91% transmission rate of normal solar glass to 96%. The improvement is especially effective with the slanted irradiation that often occurs during winter months.
