PURPOSE:To improve the performance and external appearance, by arranging a solar cell module and a ventilation device on the ridge of a roof to be slanting at the right and left sides and exhausting the heat within the solar cell module to the outside and containing the support members and wiring materials in the inside. CONSTITUTION:One of slanting faces is applied for a solar face 1' and the other slanting face is applied for a louver type ventilation face 2' and the support base 3 and wires of the solar cell module 1 and the ventilation device 2 are contained so as not to be exposed to the outside. As the rear space (a) of module 1 is prevented well from rain and the solar light is obstructed, the rear structure of module and the wiring materials are not required to apply a special protective treatment. Accordingly, the heat in the module is easily removed from the ventilation face 2' and hence the energy conversion efficiency of the solar cells does not decrease. And a ventilation face is provided on the surface as well if necessary and the solar face and the ventilation face are alternately provided to lessen the variation of the ventilation efficiency and the generated power. In this way, the design is improved and also the conversion efficiency is improved. |
