Photovoltaic + rail transit? Jul 05, 2024

Researchers from Germany's Fraunhofer ISE institute are field testing a new module concept "to be integrated into soundproof walls next to roads or railways" so that it can be applied to soundproof walls of new railways (or highways), Renovations and additional projects, etc., this will be a cost-effective design method and a new power generation solution.The research, called PVwins, began in 2020 and has developed five different integrated photovoltaic solutions that are now in the outdoor field testing phase. The team investigated the design, prototyping, manufacturing, and economic potential. and marketability. Will be used in acoustic walls and located in high traffic road and railway areas.


As listed in the figure below, from left to right.

o A combined solution with modules having two independent battery packs for light harvesting at the rear of the noise absorber and on the front (far left) of the same wall

o Transparent microporous sound absorber on the front side of the module

o Traditional photovoltaic modules mounted vertically on an obstacle facing away from the road

o Traditional photovoltaic panels mounted via brackets on top of the noise barrier, one facing east/west and the other facing south

o New cassette-shaped photovoltaic panels for retrofitting road-facing sound absorbers and tilted photovoltaic panels
