WF21 SLIC Integrated Solar Panels

WF21 Integrated Panels

The WF21 SLIC (SLim Integrated Collector) offers a standard 2.1 square meter that is thinner than most integrated panels on the market at only 92mm. What this means is a flusher looking integrated panel for the end customer and for the installer it means we can get an extra panel onto each panel in order to reduce transport costs. All this while still offering a great looking panel with high output per square meter.

Slimmer Panel Means Flusher Installation

SLIC 21 Features

  • Extremley flat design leads to smaller flashing sheets on the top edge, therby redusicng that surface area of roof required.
  • Small horizontal and vertical gaps with trim in the same colour as the flashing
  • Laser welded, full-surface absorbers made from copper
  • Highly-selective vacuum coating
  • Great appearance as they perfectly fit the available roof space
  • Seamless transition from collector to collector
  • "Riser tube" designed for good stagnation behaviour allows of r better anti-freeze protection and a low pressure drop with no thermal dilation problems
  • Optimum micro-climate inside the case by using timber as an ecological collector material
