“…Projections suggest that the global installed capacity for solar PV systems could reach 1.4 terawatts (TW) by 2030 [2]. Under the background of an intensified energy crisis and initiatives for low-carbon energy, PV power emerges as one of the most feasible alternates because of its flexible installation sites like rooftops [3,4], desert areas [5], mountainous areas [6], and coastal waters [7].…”

Slope leveling is essential for the successful implementation of ground-mounted centralized photovoltaic (PV) plants, but currently, there is a lack of optimization methods available. To address this issue, a linear programming approach has been proposed to optimize PV slope leveling. This method involves dividing the field into blocks and grids and using hyperbolic paraboloids to simulate the design surface. By programming in MATLAB, the globally optimal solution for PV slope leveling can be calculated. Engineering case studies have demonstrated that this optimization method can achieve significant cut-and-fill volume savings ranging from 58% to 78%, when compared to the traditional segmented plane method. Additionally, the effectiveness of the optimization method improves with larger site areas and more complex terrains. A parameter analysis considering slope ratio, grid size, and block size reveals that grid size has a minimal impact on cut-and-fill volume, while slope ratio and block size have a significant influence. For typical PV projects, the recommended ranges of slope ratio, grid size, and block size are 3–7%, 5–20 m, and 30–50 m, respectively, for slope leveling design. In summary, the proposed linear optimization method provides an optimal slope leveling scheme for ground-mounted centralized PV plants, with convenient operation and fast computation.

Solar energy utilization in the transportation sector is important for reducing fossil fuel consumption and achieving the grant goal of carbon neutrality. The photovoltaic noise barriers (PVNB) are recognized as a potential alternative for electric vehicle charging. This study aims to evaluate the power generation capabilities of both monofacial photovoltaic noise barriers (mono‐PVNB) and bifacial photovoltaic noise barriers (bi‐PVNB) when applied along roads with different directions and shading conditions. Results show that the daily yields of bi‐PVNB facing west, southwest, south, and southeast are 754, 819, 1101, and 894 Wh, respectively. In contrast, the daily yields of mono‐PVNB are 459, 711, 968, and 764 Wh. The bifacial gains are, respectively, 64, 15, 14, and 17%. The influence of partial shading on PV power generation is tested, and sharp decrease is observed when horizontal shading reaches 20% and vertical shading reaches 40%. In summary, the bi‐PVNB shows satisfactory power generation ability with different orientation and shading conditions. Under Shenzhen climate, the annual power generation of bi‐PVNB along east–west, north–south, southeast–northwest, and southwest–northeast direction roads are predicted to be 304, 325, 342, and 335 MWh per kilometer.
