The theoretical model of light-electricity energy characteristic driven by distributed photovoltaic energy is put forward. The energy transfer characteristics and flow in photovoltaic energy system and ice storage system are analyzed, and the energy and temperature of each component are obtained. Loss, and experimental verification of the theoretical model. The results show that the theoretical calculation results of the external cooling power of the system are in good agreement with the experimental data. The established model can better reflect the energy transfer characteristics of the ice-storage air-conditioning system and the energy consumption of each component. The photoelectric conversion efficiency of the distributed photovoltaic energy system is 13.28%, the system energy utilization rate is 7.02%, the utilization rate is 38.51%, the external cooling is 176.51W and the cooling output is 358.61W.
