The utility model discloses a passive cooling system for a solar panel. The passive cooling system comprises an over-ground cooling component, an underground heat exchange component, a second connecting pipe and a third connecting pipe. The over-ground cooling component comprises an air inlet pipe, a cold air pipe, cooling plates, a hot air pipe, a heat absorption exhaust pipe and a first connecting pipe, the back of the solar panel is covered by the cooling plates, and air penetrating inner holes are arranged on the cooling plates. Constant temperature characteristics of an underground constant temperature layer and reduction of densely covered gas along with the temperature rise are ingeniously, organically and comprehensively used, so that the solar panel can be cooled without additionally consuming electric energy, passive cooling is realized, the shortcomings of a traditional active cooling mode are effectively overcome, the technical problem unsolved in the solar panel cooling field for a long time is s
