Solar Collector EURO L20 AR

The Highest-Yielding Solar Collector

Our EURO L20 AR is a flat plate collector fitted with sunarc® anti-reflection glass. It delivers up to 10% more energy than collectors with conventional solar glass.

The EURO L20 AR is one of Europe’s highest-yielding solar collectors.

Application options of the EURO L20 AR solar collector:

  • Solar hot water preparation and space heating support
  • Single and multi family homes
  • Simple planning and installation of larger systems
  • Outstandingly suited to low sunshine regions

 

Test-winning quality

The top of the range EURO L 20 AR solar collector has impressively demonstrated its performance. It’s a major component of Wagner & Co’s COMBI line SH 1440 AR solar package which has time and again won comparative testing of solar installations by “Stiftung Warentest”, a German consumer testing agency, and in 2010 it was rated “excellent” by the German eco-consumer organization, Ökotest, which focuses mainly on environmental aspects of products.
 

  • Technologically mature 
    A premium product with top ratings in performance, quality and durability. The outcome of more than 30 years experience in developing and producing solar collectors.
  • High-yielding
    The highly transparent sunarc® anti-reflection glass, a laser-welded absorber with optimal heat transfer and the seamless all-round insulation ensure top yields.
  • Durable
    High-end materials like solar safety glass, EPDM rubber glass sealing, aluminum and copper and conscientious workmanship ensure long durability.
  • Allrounder
    The EURO L20 AR solar collector is adaptable to all local needs – fitted vertically or horizontally, on-roof, in-roof, in façade or free-standing. 
  • Fast to rack
    The EURO L20 AR is easy, fast and safe to rack with our TRIC racking system, certified by TÜV, the internationally operating German Technical Inspection Association.
     

 

         


Installing the solar collector EURO L20 AR:

  • Standard up to five collectors in series
  • Vertical or horizontal on-roof, in-roof or stand-alone racking 

EURO L20 AR technical features:

  • Collector frame of aluminum anodized silver or black
  • Environment-friendly and high-performance vacuum coating
  • Homogenous streak-free look thanks to laser welding and single plate absorber surface
  • Highly transparent sunarc® anti-reflection glass increases 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.
