OPTIMAL SOLAR CABLE SELECTION FOR PHOTOVOLTAIC SYSTEMS

Abstract

This paper presents a novel method for selecting
optimal solar cable capacity for grid-connected solar
Photovoltaic (PV) systems. The optimization method
proposed in this paper is formulated that takes into
consideration the cost of losses and solar cable
investment cost throughout the technical lifespan of the
cable. In addition, the effect of using actual field data
of different time resolution irradiation data on the
calculation of energy losses are also presented and
discussed in this paper. The key findings of the paper
suggest that oversizing the solar cable for PV system
plays an important role in losses reduction and at the
same time provide monetary savings in the long run.
