Mirror exposure bench

Methodology

The objective is to monitor the reflectivity of mirrors used in solar thermal technologies, in a real environment, namely a Mediterranean climate with salty atmosphere. 2 types of mirror samples are exposed (from 0.01 m2 to 0.25 m2) on South-oriented tilting frames. Monitoring of the reflectivity and visual inspection of the mirrors.
