摘要：
Glazed liquid photovoltaic-thermal collectors with polysiloxane encapsulation of photovoltaic cells have been developed and fabricated to generate both electric and heat energy simultaneously. The purpose of this study is to present the monitoring of the solar domestic hot water system with the new photovoltaic-thermal collector prototypes and compare the results with data simulated by a dynamic mathematical model of glazed liquid photovoltaic-thermal collector. The detailed dynamic model enables the optimization of the construction design and has been implemented into TRNSYS as a new type to allow the system simulations. Experimental measurement of solar domestic hot water system with two glazed photovoltaic-thermal collectors has been done for 6 days. Thermal energy difference for whole measured period of monitoring was less than 1.5% compare to dynamic model. Difference between measured electric energy output and modelled was 8.1%.
