This study analyzed the effect of climatic variation on PV systems' performance and economic viability in four climatic zones of Nigeria (warm desert, warm semi-arid, tropical savanna, and monsoon climate). Performance ratio was found to be high in monsoon and tropical savanna climate due to the influence of cool-moist air from the ocean, low temperature, and increased cloud cover in the region. Meanwhile, the least performance ratio was noticed in the warm desert and warm semi-arid climate due to the dusty wind from the Sahara desert, relatively high temperature, and low precipitation in the region. In order to assess the cost-effectiveness and profitability of the solar project in Nigeria, the Levelized cost of electricity (LCOE), net present value (NPV), internal rate of return (IRR), and payback period (PP) were employed. The average LCOE across the climatic zones is 0.21 $/kWh, which is lower compared to the 0.25 $/kWh grid tariff. The average NPV and IRR are found to be $31,164 and 22%, respectively, making the project economically feasible. However, the payback period was found to be ranging from 3.7 to 5.2 years. Finally, the analysis has proven that solar PV technology is economically viable and profitable in Nigeria.

尼日利亚不同气候区的光伏系统的性能和经济可行性

这项研究分析了尼日利亚四个气候区(温暖的沙漠,温暖的半干旱,热带稀树草原和季风气候)中气候变化对光伏系统性能和经济活力的影响。由于来自海洋的凉爽空气,低温和该地区云量的增加,在季风和热带稀树草原气候中发现性能比很高。同时,由于来自撒哈拉沙漠的沙尘风,相对较高的温度和该地区的低降水量,在温暖的沙漠和温暖的半干旱气候中,性能比最低。为了评估尼日利亚太阳能项目的成本效益和盈利能力,采用了平均电费(LCOE),净现值(NPV),内部收益率(IRR)和投资回收期(PP)。气候区域的平均LCOE为0.21美元/千瓦时,低于0.25美元/千瓦时的电网电价。平均净现值和内部收益率分别为31,164美元和22%,这使该项目在经济上可行。但是,投资回收期为3.7年至5.2年。最后,分析证明了太阳能光伏技术在尼日利亚经济上可行并具有盈利能力。
