摘要

Geo-dimensional analysis plays a vital role in modern energy planning by identifying suitable locations for renewable energy deployment, particularly for solar power. This study applies a multi-attribute decision-making framework using Geographic Information Systems, Analytic Hierarchy Process, and Weighted Linear Combination to evaluate solar site suitability across the Economic Community of West African States (ECOWAS). The spatial criteria were weighed and integrated to produce suitability maps. The results revealed that solar radiation in the region ranges from 3.31 to 6.73 kWh/m2/day, with approximately 84% of the ECOWAS land deemed moderately to highly suitable for solar photovoltaic (PV) installation. Niger (99.35%), Mali (96.08%), and Burkina Faso (93.36%) exhibited the highest suitabilities. These findings highlight the potential for expanding the solar energy infrastructure to improve electricity access, support sustainable development, and mitigate climate change impacts.
