The yield from the system used in this study during the first year of operation is 1,128 kWh or on average 3.11 kWh per day. In terms of array and final yields, these are 3.83 kWh/kWp and 3.46 kWh/kWp respectively. The PV array and system efficiencies are found to be 5.93% and 5.35%, respectively. The average PR for the entire monitored duration ranges between 82 to 90.3% with an average is about 85%. It is also found that the efficiency of the inverter ranges from 89.2 to 93.8% with an annual conversion efficiency of about 90.2%
