In order to improve the utilization efficiency of solar energy by traditional collector-heat storage walls in cold regions

this study takes a village house in Xinjiang Shihezi region as the research object

builds a set of photovoltaic collector-heat storage wall system

and tests the thermoelectric performance of the photovoltaic collector-heat storage wall system in the village house in cold regions under the winter climate. The results show that compared with the traditional collector-heat storage wall

the heat collection effect of the PV collector-heat storage wall system is obviously better than that of the traditional one

the average heat gain of the room of the PV collector-heat storage wall system is 51.41 W/m

and that of the room of the traditional collector-heat storage wall is 47.32 W/m

and the average heat gain of the room of the PV collector-heat storage wall system is 4.09 W/m higher than that of the traditional collector-heat storage wall

which is the same as that of the traditional collector-heat storage wall. 4.09 W/m; the electric efficiency of the PV collector-heat storage wall system fluctuates between 6% and 11%

the energy efficiency fluctuates between 7% and 26%

and the exergy efficiency fluctuates between 5% and 11%. The results of the experimental research in this paper have certain guiding significance for the application of photovoltaic collector-thermal storage wall system in the severe cold region.
