<p>PROBLEM TO BE SOLVED: To melt a snowfall of a roof by using solar heat even when the outside air temperature is low.SOLUTION: A solar heat collection part 101A collects the solar heat. The solar heat collection part 101A includes a metal plate 120A for excellently transmitting the heat. A metal plate 120B for excellently transmitting the heat is arranged along it under an inclined roof sheet metal 111. The metal plate 120A abd the metal plate 120B are respectively a part of a metal plate 120, and are integrally formed by bending one metal plate. A planar heating element 115 is arranged under the metal plate 120B, and generates heat when a power source is ON. The metal plate 120 transmits the solar heat collected by the solar heat collection part 101A and the heat generated by the planar heating element 115 to the roof sheet metal 111.</p> |
