- Both of the roofing materials 5 have no solar cell! /, And the shape of the roofing material 6 is the same as that of the normal roofing material 6, so installation on the roof is normal. This can be done in the same way as the construction of roofing material6. That is, referring to FIG. 54, the roofing materials 5 and 6 can be stacked in order from the eaves of the roof to the ridge on the basis of the horizontal piers 12 arranged at equal intervals on the base plate 7. it can.
