Test roofs and façade test stands

Operational tests under real weather and atmospheric conditions are an integral part of our technology development. They complement the standardized and controlled tests in the laboratory and, especially in combination with hardware-in-the-loop test benches, offer the opportunity to examine the behaviour of components as part of a system.

The ISFH has various outdoor test areas:

  • Hardware-in-the-loop outdoor test stand for large-format, solar thermal and photovoltaic façades (up to 50 m²)
  • Two trackable outdoor test stands with 20 m² usable area
  • Test roofs with 400 m² usable area for usability tests on solar collectors and systems as well as performance tests on collectors up to 180 °C
  • Outdoor test stand for photovoltaic modules (90° and 45° orientation)
