Abstract
Combined heat and power (CHP) systems are increasingly being considered for residential use in developed countries due to their reduced losses, high efficiency and ability to enhance grid security. This research investigates the energy, exergy and environmental analysis of a CHP system that uses both solar panels and fuel cells. Input data was obtained by analyzing the consumption pattern of a residential building in Tehran and the solar irradiance of the city. The study includes the extraction of individual energy and exergy efficiency diagrams for the solar panel, as well as their integration with the overall system. The results indicate that the system's efficiency is at its maximum when the fuel cell is introduced into the operating circuit. Additionally, the study examines exhaust emissions from the CHP system and compares them with the current practice of using the grid network and boiler. The findings reveal that the use of CHP systems can reduce environmental pollutants and pollutant emissions by up to 33 percent.
