Patent ID: 8851067

Claim:
A solar panel comprising a first conduit adapted to comprise a heat carrying medium for heat transfer between the solar panel and a surrounding environment, whereby the solar panel comprises a chemical heat pump comprising an active substance and a volatile liquid, which can be absorbed by the substance at a first temperature and be desorbed by the substance at a second higher temperature, and the chemical heat pump comprises: a first part having a longitudinal direction and comprising a reactor part, which comprises the active substance and is adapted to be heated and be cooled by an external medium, whereby the first part is positioned to be heated by sunlight, when radiation from the sun shines at the solar panel for charging of the chemical heat pump, an evaporator/condenser part comprising volatile liquid in condensed form and being adapted to be heated and cooled by an external medium, and a passage for the gas phase of the volatile liquid, connecting the reactor part and the evaporator/condenser part with each other, the chemical heat pump is designed as a hermitically sealed unit tube and the first conduit extends over the first part in the longitudinal direction of the first part in heat conducting contact with the unit tube in the first part, and a second part of the unit tube comprises the evaporator/condenser part of the chemical heat pump, the second part of the unit tube being placed in direct proximity to the first part, in particular so that it is placed behind the first part as seen in the direction of the rays from the sun.
