Recently, research and prototype development activities have been increasing to develop liquid-type photovoltaic thermal systems (L-PVTs) by combining the photovoltaic and solar thermal systems among the renewable energy systems using solar energy. In a previous study, curtain wall-type L-PVTs (CW.L-PVTs) have been proposed, which are suitable for installation using the CW method on the outer walls of buildings where the installation area is limited. The present study used the following methods to comparatively analyze the energy production between different module arrangement methods of the CW.L-PVTs to determine the arrangement method that facilitates excellent energy production efficiency. First, we analyzed the structure of CW.L-PVTs proposed to facilitate easy application to the CW method. Second, the module arrangements and the variables of the coolant channel based on them were set, and the environmental variables for the TRNSYS18 energy analysis were set. Third, we conducted the energy analysis to comparatively analyze the electric and thermal energy production of each module based on the arrangement method and the module’s surface temperature based on the outdoor temperature and solar irradiation. As a result, an arrangement method showing the highest energy production efficiency was derived.
