The Influence of the Building Integrated Photovoltaic Panels Position on the Conversion Efficiency

The paper presents the analysis of the efficiency of a photovoltaic system integrated in buildings, located in Iasi city. Generally, the position of the panels is fixed and the conversion efficiency is studied depending on the intensity of solar radiation and the operating temperature of the photovoltaic cells. The numerical model of the system and the functioning parameters determination is realized with TRNSYS software. The case study is done for variable position of the photovoltaic panel, such as horizontal and vertical-south. The results are presented in terms of the produced energy and photovoltaic panel efficiency, for annually, monthly and daily time interval.
