Photovoltaics Noise Barrier: Acoustic and Energetic Study

Abstract In the light of global warming, renewables such as solar photovoltaics (PV) are important to decrease greenhouse gas emissions. An important issue regarding implementation of solar panels on large scale, is the limited available area. Therefore, it can be interesting to combine PV with alternative applications, as a ways of not requiring "additional" space. One example is a photovoltaic noise barrier (PVNB), where a noise barrier located along a highway or railway is used as substructure for PV modules. Even though PVNB is not a novel concept, in this paper it is studied the best shape of the barrier to optimize the acoustic and energy properties
