The report indicates that highway photovoltaic noise barriers ( PVNBs) or highway solar sound barriers represent the combination of noise barrier systems and photovoltaic systems to mitigate traffic noise while simultaneously producing renewable energy.
This beneficial side effect of solar panels has become a great interest for many manufacturers to the point that they've started manufacturing photovoltaic noise barriers along highways to serve two objectives: reduce noise and harness solar energy from places with low solar obstacles.
Researchers at Germany's Fraunhofer Institute for Solar Energy Systems ISE (Fraunhofer ISE) are field-testing new module concepts to integrate into noise barrier walls alongside roadways or railways.
The research team developed five different integrated PV solutions for use in sound-absorbing walls, typically located in populated areas with busy roads and railway lines. They investigated the design, prototyping, manufacturing, economic potential and marketability.
