The invention relates to a device for heating and/or cooling a chamber (9). The device comprises at least one frame (4), at least one first light passage device (1) and at least one second light passage device (2). The fast light passage device (1) and the second light passage device (2) are arranged on the frame (4). Furthermore, at least one first intermediate chamber (3) is formed between the first light passage device (1) and the second light passage device (2). At least one thermally conductive medium is arranged in the first intermediate chamber (3). At least one heating and/or cooling element (5) is arranged on the frame (4) such that it is in contact with the thermally conductive medium arranged in the intermediate chamber (3), the device having at least one current supply unit (8) which is powered by solar energy and which is connected to the heating and/or cooling element (5).
