Abstract

TECHNICAL PERFORMANCE AND FINANCIAL ANALYSIS OF A SMALL GRID-CONNECTED PV SYSTEM IN EGYPT

E. T. El Shenawy*, Aiat Hegazy and M. Abdellatef

ABSTRACT

Photovoltaic (PV) is one of the important technologies which can efficiently use the solar energy in generating electricity and can be considered the most promising solution for the electric energy shortage in the future. PV systems can supply electricity either for isolated loads (stand-alone) or directly coupled to the electric networks (grid- connected). The present paper demonstrates the technical performance and financial analysis of a 2-kW grid-connected PV system installed in Cairo, Egypt. It gives the details of system components, installation and operation. The paper also illustrates the measured input and output parameters of the system for one year of operation such as solar irradiation, surface temperatures of the PV modules and produced electrical energy. A financial analysis based on payback period is carried out for evaluating the feasibility of these systems in Egyptian climates. The results showed that the annual average daily electrical energy produced by the system is 9.85 kWh/day, where the total annual generated one is about 3.37 MWh/year. The financial analysis showed that the payback period of the grid-connected PV system is about 8.2 years, which indicates the great benefits from these systems during the long lifetime.
