Abstract

A hybrid power and heat generating device (100) comprising: a photovoltaic solar power collector (102) configured to collect solar power from solar radiation received on an active side (103) of the photovoltaic solar power collector; and a heat exchanging unit (104) configured to cool the photovoltaic solar power collector, which heat exchanging unit includes a cooling plate (106; 404; 504; 704) arranged to transfer heat from the photovoltaic solar power collector (102) to a cooling medium. The heat exchanging unit (104) is adapted to transport the cooling medium away from the cooling plate (106; 404; 504; 704) for heat extraction from the cooling medium. The cooling plate (106; 404; 504; 704) is arranged with a gap (110) from a rear side (111) of the photovoltaic solar power collector (102) and the cooling medium is arranged to cool the cooling plate (106; 404; 504; 704) to a temperature which allows water vapor of the ambient air in the gap (110) to condensate into water on the cooling plate (106; 404; 504; 704) in the gap (110). The hybrid power and heat generating device (100) being operable in at least two operation modes; a normal operation mode in which the gap (110) is at least partly filled with condensed water, which condensed water transfers heat from the photovoltaic solar power collector (102) to the cooling plate(106; 404; 504; 704); and a security operation mode in which the gap (110) is filled with air to thereby reduce the heat transfer from the photovoltaic solar collector (102) to the cooling plate (106; 404; 504; 704).
