Organic photovoltaic (OPV) modules integrated in buildings offer many advantages over conventional PV solutions thanks to high level of integration which combines aesthetics and functionality. Whilst the benefits of the technology are clear, their thermal operation in outdoor environments is essential in order to assess their technical potential in the building industry since, as building element, their thermal behavior affects thermal comfort, electricity generation and service lifetime. This work focuses on the thermal behavior of light-weight and flexible OPV modules mounted as building elements. An experimental set-up with PV modules installed on the faces of a cube is used to test the modules at different orientations working during 2 years at outdoor operating conditions. Faiman model is used to assess the PV module temperature. The determination of empirical parameters gives an accuracy in the range of 3.0 and 4.5 ºC depending on the tilt and orientation. A strong visual degradation mainly due to delamination is observed in those faces which receive higher levels of solar irradiation along the day.
