Assessment and economic analysis of photovoltaic power generation potential on highway slope: a case study of Guangxi, China.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Highway slope photovoltaic (HSPV) systems represent a significant approach to achieving transportation-energy integration and reducing carbon emissions, as well as a crucial utilization method for renewable energy. Given the complexity of assessing the installable area of photovoltaic (PV) panels on highway slopes across large spatial scales, a regression assessment analysis was conducted using Random Forest. The results demonstrated that as of 2024, the total installable PV area on highway slopes across 14 cities in Guangxi is 0.989 km2. Furthermore, accounting for regional variations in PV system efficiency, the power generation efficiency of HSPV systems in different areas was evaluated by integration of the Analytic Hierarchy Process (AHP) and Entropy Weight Method. Based on these assumptions, the estimated installed capacity of HSPV in Guangxi reaches 155.93 MW, with an annual power generation potential of 169.03 GW · h. After conducting an economic analysis, the project is economically feasible, as evidenced by a net present value > 0, an internal rate of return > 8%, a benefit-cost ratio > 1, and a payback period < 10 years. The proposed integrated framework—combining random forest-based slope-area extrapolation with AHP-entropy efficiency evaluation—remains reliable even without high-resolution imagery, offering replicability and scalability for highway-slope PV assessments. The findings provide actionable guidance for PV siting and economic appraisal in other provinces or linear infrastructures (e.g., railways, transmission corridors).
