Electrical and thermal simulations of a building integrated photovoltaic system are currently undertaken with a transient simulation or at least a steady state program using real experimental data. However predicted results are obtained with electrical and thermal generic models partially adapted in order to present similar results as experimental. Even if several studies increase quality of computation with help of better sky temperature models, better knowledge of irradiance and part global/direct/diffuse, sun path, convective effects, a constant parameter is used in most research to characterise photovoltaic modules, NOCT parameter, taking into account level of integration of PV modules as roofing elements. NOCT provides estimation of PV module temperature rise, evaluated under STC conditions (Standard Test Conditions), in fully ventilated mounting system. Nowadays, NOCT parameter is currently used as an essential parameter for annual predicting energy production, but solution not really suitable for photovoltaic components used as roofing materials. The purpose of this work is to validate a experimental method determining an average PV module temperature according to PV integration system.
