Abstract: The photovoltaic noise barrier (PVNB), a solar noise barrier, is an innovative integration of transportation and renewable energy. It is primarily installed alongside roads near acoustic environmental protection targets in proximity to traffic lanes. PVNBs serve the dual purpose of reducing noise pollution and harnessing solar energy. The electricity generated is used for traffic lights, surveillance, and even feeding into the power grid. This helps to reduce pollution and carbon emissions and improve energy efficiency. This paper provides a comprehensive review of the current research and practical applications of PVNBs, focusing on their unique features. It systematically addresses challenges and proposes solutions concerning optimal site selection, safety standards, noise attenuation effectiveness, power generation efficiency, durability, operational maintenance, and collaborative efforts across various departments. Additionally, this paper highlights the importance of conducting advanced research into glare mechanisms, improving site selection processes, optimizing design strategies, enhancing management and maintenance systems, and conducting comprehensive life-cycle cost–benefit analyses. This research aims to offer scientific insights for designing and deploying PVNBs, thereby fostering the progressive adoption and application of distributed photovoltaics in transportation infrastructures.
