Noise barrier Tullnerfeld

The world's first traction current photovoltaic system was installed on a noise barrier at Tullnerfeld railway station.

An innovation in the rail sector

In this innovative project, conventional panels were installed on stilts with a substructure that allows different angles of inclination. In addition, new types of flexible photovoltaic modules, which are glued directly to the noise barrier, are used. The project is also considered a pilot and test project where different angles of inclination can be set to find the best compromise between efficiency, space requirements and costs. Experience is also being gained with regard to the effects of vibration and brake dust on the photovoltaic modules.

Bonded versus elevated

The installation of elevated modules is more costly than bonding alone, as it requires more space. With bonding, the entire surface of the noise barrier can be used and this is visually less disturbing than protruding elevated modules. However, more space is needed to generate the same amount of electricity.

Our contribution to the environment

By feeding directly into the catenary, existing renewable energy resources are used directly where consumption occurs. The 50 Hz grid is thus relieved and, in addition, losses for transformation and transport can be avoided.
