The Photovoltaic-thermal (PVT) collector is a single device that combines a photovoltaic module and a solar thermal collector, producing thermal energy and generating electricity simultaneously. PVT collectors produce more energy per unit surface area than side-by-side PV modules and solar thermal collectors. They can be classified into air-type and water-type collectors according to the thermal medium used for collecting heat in the collector. The water-type PVT collector tends to show better thermal performance than the air-type PVT collector. The thermal energy from water-type PVT collectors can be used in buildings for hot water and heating. It is important to understand the overall energy performance of building heating systems that work in conjunction with PVT collectors to demonstrate the potential of their building applications. The aim of this study is to analyze the performance of heating system combined with PVT collectors that are integrated on a building roof. For this study, a 1.5kWp roof-integrated water-type PVT system was installed onto an experimental house and was incorporated into its heating system. The experimental results showed that the total heat gain from the collector is 9.7 kWh, while the average thermal and electrical efficiency levels of the system are 30% and 17%, respectively. It was also found that the heating energy for the house can be reduced by 47%, as the heat gained from roof-integrated PVT system pre-heated the water used for heating system.
