The energy balance of roof integrated hybrid photovoltaic modules
A study on the energy balance and recovery potential of hybrid roof integrated photovoltaic (PV) has been made concentrating on the understanding of the most appropriate module construction materials and the mounting methods. The heat recovery in an inclined air gap together with the electrical performance of PV modules based on operating temperature has been studied in order to establish the optimal balance between electrical output and heat recovery in the system. A simulated hybrid PV roof structure has been constructed using conventional material and purpose built PV modules. Two mounting scenarios have been explored. Firstly where the PV module forms the outer surface of the roof structure with an air gap formed by an adiabatic enclosure behind and secondly, where the PV module is mounted under a cover structure thus the back surface is against the adiabatic barrier and an air gap is left directly above the module surface. Various module production prototypes have been examined to establish the appropriate technology for each option.
