A test stand is to be developed from an existing proof of concept for measuring the luminance of PV modules using a foto camera. Compared to existing solutions for determining luminance using the bidirectional reflectance distribution function (BRDF), the test stand has three main advantages: Firstly, the measurements can be made in the laboratory and outdoors (on a built installation); sec-ondly, the test equipment is inexpensive; and thirdly, very shallow angles (up to approx. 88°) can also be measured. The test stand consists of a profile spotlight, a photo camera with RAW data ex-port option, a mechanical module holder and software based on Matlab or Python, which is yet to be developed in this project. This test bench is used to measure a reduced form of the BRDF.
