Models of photovoltaic (PV) module electrical characteristics are well developed, because of the precise knowledge of the physics of semiconductor behaviour. The PV cell current-voltage characteristic is well known, and used in many models of array output. However, in many practical cases such as building-integrated photovoltaics, a model of power output only is required. Current-voltage revious researchers on which particular model should be used. This contrasts with the case of the diode model for I-V characteristics. In this work, an ef. ciency model of power output will be developed based on an adaptation of the established PV. fill factor method, and attempts are made to ground the irradiance and temperature characteristics in established theory in order to make a general PV power ef. ciency model. The model is validated using measured data from a 39.5-kW building-integrated PV array.
