Abstract
Through a power cable from a power collection box, a power conversion device receives DC power. The power conversion device converts the received DC power into AC power and transmits it to a power system. A plurality of air lead-in tubes are laid in parallel. Each of the air lead-in tubes includes a heat exchange part, an opening part, and a lead-in part. The heat exchange part is buried in a ground at a ground surface on a back surface of a solar cell panel. The opening part is exposed to the ground surface. The lead-in part is an opening that communicates with an interior of a building in which the power conversion device is installed. The air lead-in tubes are constructed to draw air in the heat exchange part from the lead-in part by using a sucking mechanism.
