Photovoltaic noise barrier (PVNB) technology combines noise control measures with renewable energy generation. In this study, it is aimed to develop an integrated design method that embeds solar energy technology in noise protection structures. The method is exemplified in an existing settlement located on the side of the road with heavy traffic.
When the alternative selected as a result of the TOPSIS method is compared with the current situation, it is predicted that the number of receiving points affected by noise will decrease by 44% and annual electricity generation will be 524,804 kWh. The study provides a useful framework for planning photovoltaic noise barrier installations.
Zhong et al. (2021) built a framework to calculate solar potential on existing and planned noise barriers based on feature extraction of street-view images. The study assumed that the PV panels would be installed on the side surface of noise barriers, namely the vertical built-on configuration.
Photovoltaic noise barrier (PVNB) is an integrated infrastructure that combine solar panels with noise barriers to collect solar energy and reduce noise. This study performed multi-criteria analysis of PVNBs in terms of energy, economic, and environmental impacts.
Besides increased biodiversity on the roof and higher solar energy harvesting efficiency during hot periods, such panels are also pre- dicted to increase noise shielding. With increasing inclination angle and especially when there are no gaps between the bottom of the panels and the green roof, positive effects become more pro- nounced.
Solar panels on green roofs were found to significantly decrease sound pressure levels at the shielded building facade, up to 5 dBA on top of the insertion loss of granular substrates. Polyurethane foam slabs as green roof substrates provide relevant shielding when placed on a series of hollow trapezium-like cores of sufficient height.
Photovoltaic effect
The photovoltaic effect is a process that generates voltage or electric current in a photovoltaic cell when it is exposed to sunlight. It is this effect that makes solar panels useful, as it is how the cells within the panel convert sunlight to electrical energy. The photovoltaic effect was first discovered in 1839 by Edmond Becquerel. When doing experiments involving wet cells, he noted that ...
