Parabolic Mirror

Parabolic mirrors (also called parabolic troughs) are not used in Central Europe. They concentrate the direct Solar Radiation on the Absorber, which is placed at the centre of the mirror, and thus can reach very high temperatures. However, most diffuse radiation cannot be concentrated in this way, and for this reason a Flat-Plate Collector or an Evacuated-Tube Collector is more useful in Central Europe.
