Off-grid communities in Ghana face challenges in accessing reliable energy sources, necessitating robust system designs to ensure continuous power supply. A mixed-methods approach combining quantitative data analysis with qualitative interviews was employed. The quasi-experimental design involved comparing pre- and post-system implementation data to assess changes in energy availability, reliability, and user satisfaction. The analysis revealed a significant increase (p<0. 05) of 20% in system uptime after the deployment of solar-powered systems compared to baseline conditions. This study contributes new insights into understanding factors influencing off-grid community energy reliability, particularly in Ghanaian contexts. Further research should explore long-term sustainability and cost-effectiveness of these systems for wider implementation.
