Photovoltaic systems Design and Cost Effectiveness Assessment for the telecommunication sites

Abstract

Renewable energy is one of the most promising technologies used to generate electricity, especially for developing countries going through phases of instability in the network. Telecommunication systems should be emphasized because of their impact on development. Consequently, the energy supply plays an important part of any communication system. It is essential to select the power source option that has the low cost and long life. This paper presents a practical design and implementation of an on-grid PV system for the local telecommunication companies in Benghazi, the companies started using solar-powered systems at many of their sites in order to guarantee continuous services. The study starts by classifying the sites according to the load size into four types: 200W, 500W, 700W and 1000W and the PV system components sizing are evaluated for each type. The hybrid system option has been chosen to guarantee continuous power supply to the load. It is concluded that the use of photovoltaic systems at telecommunication sites accomplished not just technological success but also an economical one. This study can be used for research, teaching, as well as for the telecommunication companies as an initial assessment for future grid connected PV systems installation.
