Abstract: The present thesis, aims to create simulation models, for the determination and analysis of the generated electricity, from integrated thin film photovoltaics on the roof of a building.

Replacing the building materials of a building envelope, such as facades and roof, with modern photovoltaic elements, constitutes a rising photovoltaic technology. At the same time, building integrated photovoltaics function as sources of electricity and building materials, offering savings in electricity costs, reducing the use of fossil fuels and upgrading the architectural structure of the building.

The completion of the model was carried out through the software program of TRNSYS (Transient Systems Simulation Tool), which defined the technical and constructive characteristics of the building, as well as the basic parts that make up the installation of a photovoltaic system.

 Then, a sensitivity analysis of the integrated CIGS thin-film photovoltaic panels was performed, setting the inclination of the frames at different degrees, in order to study the rate of influence and the efficiency of the photovoltaic system. In addition, the application of a different type of photovoltaic cell, CdTe was examined in order to study the efficiency of the generated electricity, modifying successively, the angle of inclination of the photovoltaic panel. From the scenarios applied for the two categories of thin film photovoltaic cells, the most efficient ones were selected and used in their further comparison, regarding the saving of electricity costs and production costs of the specific photovoltaic technology, with the ultimate goal of finding the best building integrated photovoltaic thin film solar cell technology.
