Application

  • Suitable for both new builds and the renovation of existing PREFA roofs.
  • The solar panel clamps are used to attach the solar panels directly to the double locked seams and there is no need for the roof covering to be penetrated by screws.

Description

The photovoltaic system for PREFALZ roofs is a combination of glass/glass PV panels with particular developed seam clamps and solar panel clamps in one piece, which are attached directly to the double-locked seams seams. Thus, the PREFALZ solar panels enable installation parallel to the roof with a low installation height.

The clear PREFALZ lines are harmoniously continued, which preserves the characteristic look of the roofing trays. The PREFALZ solar panel is 100% compatible with the PREFALZ roof system. Adapted to the 500 and 650 seam widths, the glass/glass PV panel is attached to the seams, which preserves the appearance of the double-lock standing seam trays.

The PREFALZ solar panels can be installed on new PREFALZ roofs as well as retrofitted to existing PREFALZ roofs at any time.

Features and benefits:

  • Parallel to the roof, maintains characteristics of the system, low build-up, adapted to the tray width of the PREFALZ application.
  • Resistant - robust, durable glass/glass PV panel with the latest TOPCon cell technology.
  • No roof penetration - the solar panels are attached directly to the double-locked seams with panel clamps, and there is no need for the roof covering to be penetrated by screws, etc.
  • Two-in-one, seam and panel clamp in one product, easy and fast installation due to the few components required.
  • Solar panels can be installed on new PREFALZ roofs as well as retrofitted to existing PREFALZ roofs.
  • Independent, economical and sustainable.
  • The sun is always available as an energy source, and the self-produced energy can be used directly, fed into the grid or stored.
  • CO2-friendly production facility.
  • The PREFALZ solar panel is developed and produced in Austria to a high standard and is 100% compatible with PREFA’s complete system.
