Performance and Reliability Analysis of an Off-Grid Pv Mini-Grid System in Rural Tropical Africa Using Actual Data : A Case Study in Southern Ethiopia
Highlights• A real-time performance analysis of a 375 kWp off-grid PV mini-grid is carried out• The average on-site PV module and overall system efficiencies are 9.85% and 8.76%• The average daily capture losses and system losses are 2.75kWh/kWp and 0.40kWh/kWp• The mini-grid operates at a temperature-corrected performance ratio (PR corr ) of 42%• The power supply from the PV mini-grid could not satisfy the daily load/demand
