In recent years there has been growing interest in Hybrid Photovoltaic/Thermal (PV/T) systems for different applications that require hot water and electricity. The hybrid system integrates the features of photovoltaic and solar thermal systems in one combined and more efficient component, reducing material, installation and maintenance costs and also the installation space. Moreover, the electricity production of a hybrid PV system can be significantly higher than that of a standard PV module, because the cell temperatures change according to the amount of heat removed by the heat exchanger installed below the panel and this directly influences the panel efficiency. The water used in the heat exchanger will be heated to the desired temperature for consumption, which will be controlled according to the water flow. Based on these considerations, the aim of this paper is to calculate and analyze the optimal installation of a PV/T system for a low-income residence, according to the demand for electricity and hot water in different Brazilian cities. Simulations of water-based PV/T systems for domestic application were performed with TRNSYS software followed by a detailed energetic analysis. The parameters used in the software were developed from theoretical equations.
