This paper presents the first year (2014) performance analysis of a 276 kWp grid-connected roof-type solar PV plant located at the campus of Al-Ahliyya Amman University in Jordan, using monitored data. The plant is installed on 3000 m2-roof of Arena building at the University campus. The array consists of 1176 modules with two orientations 10° and 15°. The PV array is configured in a way that the system includes 14 panels in parallel with 14 inverters. The plant is equipped with a monitoring system which is connected to the internet and gives the data on a daily basis. The study shows that the actual and estimated specific energy productions are 1639kWh/kWp-year, and 1726 kWh/kWp-year, respectively. The annual capacity factor and performance ratio are found to be 18.7% and 87.5%, respectively. The actual energy production is found to be 452406 kWh/year, whereas the estimated annual energy production is found to be 476467 kWh as calculated using the software PVsyst V6.32. The measured and estimated yields are in close agreement to each other with a relative error of about 5%. It is found that the maximum actual yields in July and minimum in January. Compared to PV plants worldwide, and particularly in detail to a PV plant in Syria, the analysed plant (the AAU plant) has an excellent overall performance.
