Title: Influence of the Orientation of PV Installations Without Energy Storage on Their Operational Efficiency
Keywords: Optimal PV design, PV orientation, Time distribution of PV generation

Abstract: The problem for optimal orientation and inclination of PV modules can be considered completely solved when total annual generation is taken into account. The south orientation and optimal inclination angle, for a given location, are available and the adequacy of the data is statistically proven. Not optimal designs with East/West orientation of PV panels gain increasing popularity. The hourly distribution of the generated energy and significant variation of the electricity price encourages more and more users to prefer a non-canonical arrangement of the panels, which, however, equalizes as much as possible the load diagram of the generated energy. In the present work, a simulation study of the possible benefits of East/West orientation of photovoltaics is presented. Both, residential and commercial installations are considered. The generated energy is simulated and possible benefits are estimated. The profit (or loss) due to the electricity price variation is also studied. The possible match between the generation and load schedules in the case of residential load is shown. The cases when East/West orientation is beneficial compared to the optimal design are determined.
