Evaluation of Wind and Solar Energy Potentials over Maiduguri in the Sahelian Climatic Zone of Nigeria

The evaluation of wind and solar energy potential in Maiduguri is essential for addressing energy challenges, supporting sustainable development, and promoting socio-economic growth while mitigating environmental issues. This study analyzes ۳۹ years of meteorological data (۱۹۸۴ to ۲۰۲۲) to evaluate wind energy potential through the Weibull distribution function and estimates solar energy potential by calculating the electrical power generated from a single photovoltaic panel in Maiduguri. The results revealed that the monthly mean wind speed has its highest value to be ۴.۷۸۶۹ 〖ms〗^(-۱), in February and the least to be ۲.۵۴۹۵ 〖ms〗^(-۱), in September. Maiduguri has its highest value of temperature to be ۳۳.۲۱۲۳ ℃ and the lowest to be ۲۳.۰۹۳۶℃. The highest solar radiation in March was observed to be ۲۷۲.۱۰۴۷ 〖Wm〗^(-۲) and the lowest in August as ۲۱۲.۴۱۴۵ 〖Wm〗^(-۲). The wind power density for Maiduguri has its highest value to be ۶۳.۷۷۳۱ 〖Wm〗^(-۲) and its lowest value as ۹.۶۳۴۴ 〖Wm〗^(-۲), which ranged between ۰-۹۹ 〖Wm〗^(-۲)and falls in the class ۱ of the PNL wind classification, suitable for small-scale wind turbines. The most probable wind speed was determined to be ۴.۷۲۷۱ 〖ms〗^(-۱) and the highest monthly maximum energy carrying-wind speed was ۴.۹۳۲۵ 〖ms〗^(-۱). The Weibull statistics' two parameters were discovered to lie between ۸.۱۹۴۶ ≤k ≤ ۲۰.۲۴۸۵ and ۲.۹۹۷۷ ms^(-۱)≤c ≤ ۴.۸۵۴۷ ms^(-۱). The estimated solar PV output power was highest with ۱۸.۶۵۰۵ W in March. The correlation between monthly wind power density and solar radiation in Maiduguri is ۳۸.۱۲%, indicating its potential for simultaneous electric power generation.
