Physical models for the design of photovoltaic/thermal collector systems

摘要

Solar photovoltaic thermal (PV/T) systems have the capacity to become a key actor in the world's energy transition. The design of such systems requires the implementation and development of physical models, which can predict their thermal and electrical performances. In this paper, some of the main models for designing PV/T systems are developed. In fact, various configurations of equivalent-circuit models are presented to perform the electrical behavior of PV/T systems. Further, a Quasi-Steady Thermal Model (QSTM) is developed to forecast thermal performances. All reported models are validated based on the literature results. The efficiency analysis of developed models demonstrates that the good choice of equivalent-circuit model is substantial and varies according to the climatic changes. Limitations of certain electrical models have also been outlined and discussed. This work could be a guideline to researchers for the physical modelling of PV/T systems.
