PURPOSE:To slide and drop ice and snow deposited on a light-receiving surface effectively by additionally pasting an upper air-receiving heat absorbing plate on the upper end of the light- receiving surface, also hanging a lower air-receiving heat absorbing plate from the lower end of the light-receiving surface and covering the light-receiving surface between these heat absorbing plates with a unified transparent film when a plurality of bird avoiding bars are studded to the upper end of the light-receiving surface on which a lorge number of solar cells are loaded. CONSTITUTION:A light-receiving surface 2 on which a large number of light-receiving elements 3 are loaded is mounted obliquely to an installation base 1, and a plurality of bird restraining bars 4 are studded to the upper end section of the light-receiving surface. An upper air-receiving heat absorbing plate 11 is pasted additionally to the light-receiving surface, a lower air-receiving heat absorbing plate 14 is hung from the lower end of the light-receiving surface 2, and a transparent film supported by extending wires 12 is pasted on the light-receiving surface 3 while being connected to the heat absorbing plates 11 and 14. Accordingly, the film 13 is vibrated by the force of air while the lower surface of ice and snow laminated on the light- receiving surface 2 is melted by solar heat generted in the heat absorbing plates 11 and 14, and ice and snow are slide and dropped. That is, a seesaw motion is generated in the light-receiving surface 2, coating snow is shaken down, and the efficiency charging is improved. |
