Solar simulator for large building components


© Fraunhofer IBP
Measurement Thermal load tests, spontaneous failure, temperature of building components, g-value (SHGC/total energy transmittance), fitness for purpose, aging behaviour, thermal expansion, fogging of closed glass façades
Standards Alternative method to DIN EN 410, DIN EN 52022-3, DIN EN 4892
Measurement object Façades and roof components with opaque, translucent or transparent partial areas, transparent building components with light-directing elements, sun protection or shading facilities, also in interspace between the panes, glazing with integrated photovoltaics

Technical data

Irradiated area 1 to 8 m²
Effective irradiance 500 to 1200 W/m²
Sun elevation angle 0 to 90°
Quality of radiation Solar-near spectrum, mainly parallel beams, variable diffuse component up to 100 % possible
Installation of the specimens Wall to roof (0 to 90° continuously)

Special features

  • The solar simulator reproduces almost all global radiation loads on building components in their original size and original mounting position. Smaller specimen can be irradiated with higher intensity, e.g., aviation
  • Weather-independent test facility with reproducible boundary conditions


More information

  • For long-term weathering testing and thermal load tests additional solar simulation facilities for sizes between 180 × 260 mm and 4 m² are available.
  • Standard tests according to relevant standards for long-term weathering under combined exposure to UV-A radiation, temperature and condensing humidity or spraying are also possible in seperate test facilities on request.
