Abstract

The energy pile-building integrated photovoltaic/thermal （BIPV/T） system recovers the waste heat from photovoltaic power generation and stores it in the soil around the energy piles

maintaining the soil thermal balance around energy piles while enhancing the photovoltaic efficiency. To promote the application of the system

this study selects four representative cities in China's severely cold and cold regions to explore the system's performance in different regions. By establishing the dynamic system model on TRNSYS platform

the systems in the four cities are designed under the same operation strategies and their performances are compared. The results indicate that due to the highest heating demand for the building in Harbin

the required solar heat storage capacity is the highest for the soil

reaching 130.91 MWh. The BIPV/T collector has the highest electric efficiency and output in Harbin

being 19.31% and 73.29 MWh respectively. The photovoltaic modules in Xining have the highest heat collection efficiency

which is 36.24%. The system exhibits the best energy-saving performance in both Harbin and Xining

with energy savings rates exceeding 96%. Additionally

the system also demonstrates good economic viability during long-term operation. This system promotes the application of renewable energy in buildings and achieve low-carbon emission in the building sector.
