| Popis: | Photovoltaic&ndash thermal collector generates electrical and thermal energy simultaneously from the same area. In this paper performance analysis of a potentially very promising application of a glazed photovoltaic&ndash thermal collector for domestic hot water preparation in multifamily building is presented. Solar system in multifamily building can be installed on the roof or integrated in the faç ade of the building. The aim of this simulation study is to show difference of thermal and electrical performance between faç ade and roof installation of a glazed photovoltaic-thermal collectors at three European locations. Subsequently, this study shows benefit of photovoltaic-thermal collector installation in comparison with side-by-side installation of conventional system. For the purpose of simulation study, mathematical model of glazed photovoltaic-thermal collector has been experimentally validated and implemented into TRNSYS. A solar domestic hot water system with photovoltaic&ndash thermal collectors generates more electrical and thermal energy in comparison with a conventional system across the whole of Europe for a particular installation in a multifamily building. The specific thermal yield of the photovoltaic&ndash thermal system ranges between 352 and 582 kWh/m2. The photovoltaic&ndash thermal system electric yield ranges between 63 and 149 kWh/m2. The increase in electricity production by the photovoltaic&ndash thermal system varies from 19% to 32% in comparison with a conventional side-by-side system. The increase in thermal yield differs between the faç ade and roof alternatives. Photovoltaic-thermal system installation on the roof has higher thermal yield than conventional system and the increase of thermal yield ranges from 37% to 53%. The increase in thermal yield of faç ade photovoltaic-thermal system is significantly higher in comparison with a conventional system and ranges from 71% to 81%. |
