Abstract

This paper presents the performance analysis of a 23 MWp photovoltaic solar power plant installed in Diass, Senegal. The solar photovoltaic power plant is composed of 85608 polycrystalline PV modules and 8 transformer stations (TS). Each TS consists of 4 inverters, several DC BOX and 2 transformers. The environmental and performance data of the plant used in this work were recorded throughout the year 2020. The performance parameters evaluated in this work are array yield, reference yield, final yield, array capture losses, system losses, performance ratio and capacity factor. The results of this study have been compared to other work carried out around the world. The results show that the performance depends on the climatic conditions of the on-site installation and the technologies used.

Key words:  Performance analysis, power plant, performance data, environment data, PV plant, grid connected.
