Photovoltaic (PV) solar energy system converts sunlight to electricity and referred as one of promising system for production of a renewable energy resources. Tilt angle and orientation have important effect on PV output. Positioning of PV system using tilt angle and orientation, therefore, according to path of radiation of sunlight is very critical to obtain more efficient energy conversion from PV panels. In this study, determination of optimum tilt angle and orientation studied for a grid-connected hybrid wind-PV-battery system. Firstly, general calculations of PV completed using a numerical method as follow: annual solar radiation (Wh/m2), annual energy production using radiation and temperature (Wh/m2), energy production using radiation, temperature and wind speed (Wh/m2). Secondly, cost of electricity for a grid-connected wind-PV-battery hybrid systems ($/year) depending on solar radiation, weather conditions and electricity market data were obtained using numerical method. It founded that optimum tilt angle varied between 26° - 27° for first three scenario and for the last case is 9°. As for orientation, it changed from south to west for all cases. Moreover, it seems that results of this study might be a reference and preliminary study for scientist and researcher/engineers to simplify designing and evaluating PV system.
