SunScreen is a photovoltaic noise barrier. Its high acoustic performance reduces noise along road and rail transport network, thanks to its innovative design and absorption capacity.

By using the unused location and structure of the available noise barriers as support for photovoltaic panels, SunScreen makes renewable electricity production competitive, even in urban areas. Every kilometer of barrier corresponds to 1200 photovoltaic panels and provide about 400 kWp of power. SunScreen is addressed to highway private concessionaires and public operators. SunScreen offers them the possibility to increase the environmental and social integration of their project, by reducing noise levels and producing renewable and low-carbon energy.

Implementation Stories

SunScreen by TechSafe Industries
Implemented by VINCI Autoroutes in Tours (France) in 2020

VINCI Autoroutes, a highway concessionaire, was willing to extend a noise barrier to protect the neighborhood near the A10 highway in Tours, in the Central Region of France. The first 100-meter long and 3-meter high wall was installed in 2020 on the edge of the road. Corresponding to 114 photovoltaic panels with capacity of 300 Wp/panel, it enables the production of 34,2 kWc of peak power. The client is intending to extend this concept to many other kilometers of highway.


34,5 mwh annual electricity production & 34 t / year co2 avoided compared to coal power


The environmental benefits

  • 100 meters of photovoltaic noise barrier would enable to avoid 29 tons CO2e over 30 years in France and 441 tons CO2e in Germany
  • Every kilometer of barrier corresponds to 1200 photovoltaic panels and provide about 400 kWp of power

The Financial benefits

  • Total cost of ownership is lower than the alternatives: payback time of 16-24 years (over a mininum 30 years lifetime)
  • Annual maintenance cost < 0,5% of CAPEX
