Harnessing Solar Energy in Ewekoro, Ogun State: Opportunities and Economic Impact
Subject area: Physical Sciences and Environment · Area of research: Solar Power
Abstract
This study investigates the solar energy potential of Ewekoro, a rapidly industrializing region in Ogun State, Nigeria, with a view toward assessing its viability for sustainable power generation and its broader economic implications. Utilizing high-resolution ERA5 satellite data from 2014 to 2023, Essential solar radiation metrics, encompassing shortwave radiation in both all-sky and clear-sky scenarios (ssrd, ssrc, ssrdc) and thermal radiation (str, strd, strdc), were examined to assess the feasibility of photovoltaic (PV) energy harvesting. Research indicates that Ewekoro receives an average of 1.64 MJ/m?/day of all-sky solar radiation (ssrd) and 2.36 MJ/m?/day under clear-sky circumstances (ssrdc), confirming its appropriateness for solar systems. The results revealed consistently favorable solar radiation values, with average daily shortwave radiation exceeding 1.5 MJ/m??surpassing the minimum threshold required for basic PV system viability. Time-series analyses, boxplots, and histograms affirmed the stability and reliability of solar energy availability in the region, even under varying sky conditions. Further, the study explores the economic prospects of deploying decentralized solar power in Ewekoro, particularly in reducing dependence on fossil fuels, stimulating job creation, and powering industrial and rural communities. The local cement and mining industries stand to benefit immensely from the integration of solar technologies, enhancing productivity and cost-efficiency while minimizing environmental impact. Additionally, stable clear-sky radiation profiles and thermal moderation patterns indicate favorable conditions for long-term solar infrastructure with minimal performance degradation. By aligning with Sustainable Development Goals (SDG 7 and SDG 13), this research supports policy recommendations that promote investment in solar energy infrastructure, public-private partnerships, and energy access equity in underserved areas. The findings serve as a strategic roadmap for energy diversification and economic transformation in Ogun State and beyond.
