BBC Radio 4 interview with Prof Ralph Gottschalg


Prof Ralph Gottschalg gave an interview to BBC Radio 4 discussing the benefits of photovoltaic systems on industrial buildings. In this context he mentioned that the installation of east-west facing systems would be extremely beneficial as it generates for longer times of the day and allows to pack more modules onto a roof without causing shading. While it is true that these systems produce a little bit less energy per unit (around 10%), there are significant cost savings associated with such an installation that it may overall be preferential to install this way.
