Abstract

Abstract: This paper presents an evaluation of east–west oriented photovoltaic power system. The evaluation is done based on a simplified model for east–west oriented photovoltaic system. This model is developed mathematically then implemented by using Matlab. The model is also validated by a commercial software and experimental data. After that, a comparison between east–west oriented photovoltaico system and south oriented photovoltaic system in terms of cost of energy and technical requirement is conducted. In addition to that, the benefits of using east–west oriented photovoltaic system are discussed in this paper. Results show that the proposed model is accurate in predicting the output power of east–west oriented photovoltaic system. It is also found that east–west oriented photovoltaic system requires less land area. Moreover, it is found that east–west oriented photovoltaic system requires less cost for mounting piles and steel structure, and less costs of the interfacing power substation especially in case of photovoltaic systems slanted at high tilt angle. However, it is found as well that the south oriented photovoltaic system produces more energy than east–west oriented photovoltaic system. It is also found in this research that there is no significant difference between the costs of energy for both systems. Finally it is concluded that for direct grid interfacing east–west oriented PV system can provide smoother power injection to the grid with fewer harmonic and less reverse power. On the other hand, south oriented photovoltaic system is preferred when high power injection is required.
