|Abstract:||This paper presents a method for the calculation of the carbon footprint of hybrid PV/T modules. PV/T modules produce heat in addition to electricity compared to conventional photovoltaic modules which only produce electricity. The electric and thermal yields of the PV/T system depend on the tempera-ture difference between the ambient temperature and the heat sink. The PV/T system is compared to a conventional system based on a combination of a conventional photovoltaic module and a solar thermal collector for different temperature differences between the ambient temperature and the heat sink. The operation of the PV/T system and the conventional system are analysed for three different locations in different climatic regions of Switzerland. The PV/T system has a higher electric yield compared to an equivalent conventional system consist-ing of a conventional photovoltaic module and solar thermal collector due to the optimised operating temperature of the photovoltaic cell in the PV/T system. The advantage of the PV/T modules compared to a system with separated photovoltaic and solar thermal systems is most pronounced in the region north of the Alps. PV/T modules are suitable particularly for locations where a borehole with a geothermal probe with low outlet temperatures is available.|
