The lack of fossil fuel resources on one hand and increasing efficiency and reducing the costs of using renewable resources on the other hand have led to a significant increase in the use of these resources in recent years. The most important of these sources is solar energy. Photovoltaic-thermal (PVT) systems are a type of solar system that produces electricity and heat simultaneously. In this article, a photovoltaic-thermal (PVT) system has been compared with a solar water heating (SWH). Two systems with almost identical equipment have been modeled using TRNSYS (v18). The modeling results show that although the heat obtained in the thermal photovoltaic system is slightly less, the electrical energy produced by it is more than this difference in heat production. Also, due to the higher intrinsic value of electricity than heat, the use of these systems has more technical and economic justification.
