  "textContent": "Through a power cable 12 from a power collection box 10, a power conversion device 3 receives direct current power. The power conversion device 3 converts the received direct current power into alternate current power and transmits it to a power system (not shown). A plurality of air lead-in tubes 20 are laid in parallel. Each of the air lead-in tubes 20 includes a \"heat exchange part\", an \"opening part\", and a \"lead-in part\". The \"heat exchange part\" is buried in a ground 60 at aground surface on a back surface of a solar cell panel 4. The \"opening part\" is exposed to the ground surface. The \"lead-in part\" is an opening that communicates with an interior of a building 2 in which the power conversion device 3 is installed. The air lead-in tubes 20 are constructed so as to draw air in the heat exchange part from the \"lead-in part\" by using sucking means. As the sucking means, a lead-in fan 22 for circulating air inside the air lead-in tube 20 is provided.",
