• Performance model for (C)PVT collectors is presented.
• Electrical and thermal power outputs are parameterized in analogy to quasi dynamic model.
• Comprehensive description is enabled based solely on standard measurement data.
• Exemplary application of the model is demonstrated.
• Implementation into standardization of (C)PVT collectors is recommended.
A performance model is presented that enables yield predictions of hybrid photovoltaic and thermal (PVT) collectors. It applies for both non-concentrating (PVT) and concentrating (CPVT) systems. The model is based on considerations on energy balance, heat transfer and the dependence of the photovoltaic efficiency on absorber temperature. Similar to the quasi dynamic model for thermal collectors, linear parameterizations of both electrical and thermal power outputs are derived. The respective linear coefficients are obtained from multi-linear regression on solely standard measurement data.The model is applied to measurement data of a CPVT collector to exemplify the procedure and to validate the model. Good agreement of empirically determined collector coefficients with expectations from known parameters is achieved.
