Solar Traffic Route Element


Sealed traffic surfaces such as highways and freeways usually offer unshaded space suitable for electricity production. Previous attempts to install solar panels on roadways were unsuccessful because the disadvantages of such systems were too severe. But why don't we install systems above the roadway in a safe and cost-effective way?

With the Solar Traffic Route Element, sealed surfaces such as expressways and highways can be sensibly opened up for solar energy generation. The universal mounting allows all photovoltaic modules to be installed and offers not only an efficient energy supply but also a reduction in noise emissions and heat protection in summer. 

Proven skeleton construction

The basis for the Solar Traffic Route Element is a steel or concrete structure equipped with special, inclinable mounts for PV modules. In its basic state, the construction is closed and the resulting noise is retained. Rain, snow and heat penetrate to a much lesser extent to the asphalt surface, so that it has a longer service life. Secondary effects in the case of traffic jams are the reduced use of air conditioning and thus a saving in energy and CO2 of the vehicles.

  • Rapid installation
  • Skeleton construction made of structural steel or concrete
  • Inclination of the modules possible
  • Increased fire protection through lightning smoke extraction

Lightning smoke extraction, emergency opening and snow protection

In accordance with the legal requirement, the solar traffic route element makes it possible to continuously adjust the fresh and exhaust air flow to the traffic conditions. In case of fire, the PV modules are immediately tilted so that the fire cannot spread over a large area in the underpass. In parallel, an opening of the side elements ensures a safe escape to the outside area at ground level. This is possible at almost any point.

During the whole year, the Solar Traffic Route Element provides rain protection that prevents aquaplaning. In winter, the tilting arrangement of the PV modules results in high efficiency of electricity production. If snow falls on the structure, it slides off the tilted PV modules. These can thus generate energy again.
