Therefore, this study proposes a potential assessment method for expressway slope photovoltaics (ESPV) using a GIS-based DEM of the expressways, implementing the method to Fujian Province, China and evaluating the social, economic, and environmental benefits comprehensively. The main purposes of this study are listed as follows:
The analysis revealed that a total of 3123 km of expressways in Fujian Province are deemed suitable for PV development. Among these, 3006 km of expressways are suitable for installing PV panels on one side, while 117 km of expressways are suitable for installing PV panels on both sides.
Analysis of the distribution of PV potential across different slope angles (Fig. 4 b) reveals that the PV potential in Xiamen and Zhangzhou is primarily concentrated on slopes with angles less than 9°, accounting for 73.91 % and 70.04 % of the total PV potential on expressway slopes in these cities, respectively.
Normalized productions for the first year of each slope direction: (a) South-facing Slope; (b) East-facing Slope or West-facing Slope; (c) Southeast-facing Slope or Southwest-facing Slope. In this study, the conversion efficiency of PV power generation is assumed to be 18.14 % (Ashok Kumar et al., 2020).
