Abstract

Kenyan government set a goal to attain universal electricity access by 2022 to achieve economic and productive sector ambitions outlined in Vision 2030. This paper proposed to determine the performance of solar PV mini grids by investigating the technical, economic, and environmental parameters that indicate sustainability based on an actual mini grid. Solar energy resource information was gathered using equipment specific remote monitoring portal and mini grid operator documents. Technical parameters were investigated while economic tools were deployed to evaluate the performance of the project. Technical evaluation deduced that the mini grid had a performance ratio (PR) of 60.46% and capacity factor (CF)of 12.55%. Economic analysis showed that the mini grid had a high Internal Rate of Return to guarantee a payback period not erceeding 7 years factoring in minimal operation ampersand maintenance. Environmental impacts analysis of the mini grid demonstrated the benefits in avoided GHG emissions. The study concladed that solar mini grids could maintain economically reasonable performance within 20 years lifespan

太阳能微型电网的技术、经济和环境性能:以伦巴岛微型电网为例

肯尼亚政府设定了到2022年实现普遍供电的目标，以实现2030年愿景中概述的经济和生产部门的雄心壮志。本文提出通过研究太阳能光伏微型电网的技术、经济和环境参数来确定其性能，这些参数表明基于实际的微型电网的可持续性。利用设备专用远程监控门户和微型电网运营商文件收集太阳能资源信息。研究了技术参数，同时采用了经济工具来评估项目的绩效。技术评价结果表明，该微型电网的性能比(PR)为60.46%，容量系数(CF)为12.55%。经济分析表明，考虑到最小的运行和维护费用，微型电网具有较高的内部收益率，保证投资回收期不超过7年。对微电网的环境影响分析表明了微电网在避免温室气体排放方面的效益。研究得出结论，太阳能微型电网在20年的使用寿命内可以保持经济合理的性能
