In its efforts to attain climate neutrality, the Ministry of Transport Baden-Württemberg wants to extend the use of photovoltaic systems (PV) to noise control structures (NCS). To this end, the potential of this concept must be analyzed, taking into account legal requirements and technical feasibility. Further relevant aspects also need to be considered, such as planning, orientation, shade, installation and maintenance, connectivity and nearby energy consumers, e.g. proximity to urban settlements, charging stations. Ensuring or even enhancing the acoustic function is, of course, still of primary importance.
