    ABSTRACT: Planning a photovoltaic (PV) system is complex. Many different factors must be taken into account such as site information, module type and inclination of the modules, level of irradiation, choice of the most suitable inverter, etc. To ease the planning process, computer based tools must be utilized. In this paper, a MATLAB-based modeling tool to design, predict and analyze grid - tied PV systems is presented. This software has a user friendly interface which requires a minimum of data in order to present your optimum system and examine its performance in a clear graphical form. The user can explore different combinations and scenarios to meet the proposed design requirements. Simplicity, accuracy and ability to adapt the designed tool to any updates in both site information and system components would probably make it an excellent tool for educational and research purposes.

    ABSTRACT: The main objective of this project is to design a comprehensive tool that performs technical and economical analysis for building integrated photovoltaic (BIPV). This tool will be used to propose a BIPV villa design for the UAE real-state market. MATLAB-based tool was designed to perform a full technical and economical analysis for grid-tied PV systems. The designed tool carries out number of consecutive technical analysis procedures. A large database that includes various PV modules and inverters is used. The developed tool is flexible and can be easily adapted to changes in PV technologies and weather data worldwide.

    ABSTRACT: Technologies of solar energy offer a clean, renewable and domestic energy source, and are essential components of a sustainable energy future. Conventionally, PV modules used to be located over the roof, but presently and with the advances in photovoltaic technologies a new emerging field of application science the building integrated photovoltaic (BIPV) is taking place worldwide. In this newly emerging field PV cells are incorporated with horizontal and vertical elements of the building envelop such as windows and solar louvers. In this paper a computer modeling tool is developed to predict PV system power generation in typical housing of the United Arab Emirates (UAE). This MATLAB-based tool uses daily weather data for the location in UAE under investigation. A large database that includes various PV modules and inverters was built. Using this tool, 20 degree PV module tilt angle proved to produce the maximum power across the whole year in Al-Ain city - UAE. The results obtained were validated in comparison to other data collected from different cities. Moreover, this tool is flexible and can be easily adapted to changes in PV technologies and weather data.
