Analytical Model and Experimental Validation of Optical-Thermal-Electrical Performance of Bifacial Photovoltaic Systems
摘要
Abstract
[Objectives]Bifacial photovoltaic(BPV)can provide rear-side gain and has promising development prospects.However,how to accurately analyze the performance of BPV systems under coupled environmental conditions has become one of the urgent issues to be addressed.To this end,an optical-thermal-electrical-environmental coupling(OTEEC)model is proposed to explore the optical-thermal-electrical performance of BPV panels in real environments.[Methods]Firstly,the propagation path of light in the BPV system is simulated based on the Monte Carlo ray tracing method to obtain the non-uniform irradiation distribution on the front and rear sides of the BPV panel.Then,the system's thermal-electrical performance is calculated using the finite volume method and the discrete integral method,respectively.Finally,the model is validated through experiments and compared with the existing optical-thermal-electrical coupling(OTEC)model.[Results]On both cloudy and sunny days,the maximum relative errors between the irradiation distribution on the front and rear sides of the BPV panel obtained from the OTEEC model and the experimental data are less than 13％.On windless cloudy days and windy sunny days,the maximum relative errors between temperature data and instantaneous electric power obtained from the OTEEC model and the experimental results are less than 11％.Moreover,the calculation accuracy of the OTEEC model is higher than that of the existing OTEC model under both windy and windless conditions.[Conclusions]The OTEEC model has good universality and reliability,provides a scientific basis for the performance enhancement,operation scheduling,and management of BPV systems.关键词
