Abstract：Taking the civil residential model in Jinan area as the research object,comprehensively considering factors such as the presence or absence of photovoltaic panels,different seasons,roof materials,and the presence or absence of air conditioning indoors,multiple working conditions are designed to simulate the temperature distribution under different conditions,and the impact of photovoltaic panels on indoor thermal comfort is evaluated.The results show that in non-air-conditioned rooms in summer,photovoltaic panels can reduce the indoor operating temperature by approximately 3.22℃.In air-conditioned rooms in summer,photovoltaic panels can reduce the indoor operating temperature by approximately 3.54℃.In non-air-conditioned rooms in winter,photovoltaic panels can increase the indoor operating temperature by approximately 1.09℃.In air-conditioned rooms during winter,photovoltaic panels can reduce the indoor operating temperature by approximately 1.14℃.Installing photovoltaic panels on the roof can effectively improve the indoor thermal environment and enhance indoor thermal comfort.
