Abstract Dust deposition on Photovoltaic (PV) surfaces reduces the amount of radiation received by the solar cell, which decreases the energy output of solar PV systems. In this study, the process of dust deposition on three different photovoltaic parking lot structures, including a mono-pitch canopy, a duo-pitch canopy, and a barrel-arch canopy is numerically investigated for the first time. The results show that a slight variation of the tilt angle has no significant effect on the dust deposition behavior. However, the size of the dust particles has a strong influence on the amount of dust deposition. The tendency for dust deposition is found to increase first for small-sized particles and then to decrease with increasing particle diameter. Duo-pitch electric vehicles parking lots (EVsPLs) provide better performance against dust deposition compared to the other EVsPLs for most particle diameters. Mono-pitch EVsPLs, however, are more effective than the others at lower Reynolds number, Re=143,000, and small-sized particles for . In addition, medium-sized particles, , are found to be more prone to deposit on PV surfaces. The main novelty of the present study is that it offers a new perspective on the selection of the best structure of parking lots depending on environmental conditions, especially in areas with high dust concentration.
Highlights Numerical simulation of turbulent wind flow and dust deposition over PV parking lots. Study the effect of structure, tilt angle, Reynolds number, particle size on soiling. Provide a range of dust particle sizes for adjusting the self-cleaning systems. Introduce the best parking lot based on the performance in environmental conditions.
