Performance Analysis of Grid-Connected Solar Photovoltaic Systems Using Analytical Methods

Sharanya K

Abstract


The fast growth of solar photovoltaic (PV) power plants connected to the grid necessitates accurate performance verification to ensure that energy production remains effective. One MW grid-connected solar PV system has been studied and this article shows the solar PV system's performance by using indicators such as the Performance Ratio (PR), Capacity Factor (CF), and system efficiency as a whole. The finding of the computations demonstrates that the system is capable of generating around 1400 MWh of energy annually and that the Performance Ratio is 75-80% whereas the Capacity Factor is 15-18%, these levels are very good in comparison with control. This paper also examines the different types of losses that take place in the system, e.g. temperature losses (8-12%), soiling losses (3-6%), inverter losses (2-4%) and wiring losses (1-2%). The study finds temperature and dust to be the two largest factors that negatively impact system performance. Besides cleaning regularly, a modern system design could yield an extra 5-7% of energy production. In brief, this study lays the groundwork for further research to improve the efficiency, reliability, and long-term performance of grid-tied solar PV systems in real operating conditions.
