Abstract

This study establishes a light-thermal-electrical model for mono-facial and bifacial photovoltaic noise barriers (PVNB), and its accuracy is validated with experimental data. The model is used to assess the PV power generation potential of road noise barriers in the cities of Beijing, Shanghai, and Guangzhou. Results show that the total install capacities of PVNB on highways and major roads in Beijing, Shanghai, and Guangzhou are 1421.52, 1391.29, and 1939.20 MW, respectively, with annual power generation reaching 762.07, 732.86, and 1039.54 GW·h. The PV power generation costs for the three cities are 0.66, 0.67, and 0.66 CNY/(kW·h), respectively, approaching grid parity.
