Abstract: A roof system utilizing a solar cell comprising a first modular roof member composed of a plurality of first light collecting plate segments each of which having a solar cell embedded therein, the first light collecting plate segments being aligned in one direction and in the other direction perpendicular to the one direction; and a second modular roof member composed of a plurality of second light collecting plate segments each of which is equal in size to the first light collecting plate segment, the second light collecting plate segments being aligned in one direction and in the other direction perpendicular to the one direction, the number of the second light collecting plate segments in one direction being larger by one than that of the first light collecting plate segments.

Abstract: A roof mounted light transmitting frame has a pair of longitudinal sash members. A light-transmitting sheet support sash member is mounted obliquely along the inner surface of each longitudinal sash member such that the distance between its front end and the lower edge of the longitudinal sash member is larger than the distance between its rear end and the lower edge of the longitudinal sash member. A lower horizontal sash member with a vertical support member is mounted between front ends of the light-transmitting sheet support sash members. An upper horizontal sash member is mounted between rear ends of the light-transmitting sheet support sash members. A light-transmitting sheet is mounted between the light-transmitting sheet support sash members, and the upper and lower horizontal sash members. A recess is longitudinally formed on the lower horizontal sash member to receive an upper horizontal sash member of the next frame.

Abstract: A roof mounted solar collector structure has cross-pieces arranged at regular intervals parallel to the eaves line on overlying roof members which enclose a part of the roof structure. Connecting members are mounted orthogonally on the cross-pieces at regular intervals. Solar energy collection members are laid between the connecting members. Support members are mounted at peripheral edges of an enclosed part of the roof to cover upper side and outside surfaces of the crosspieces. A lower end of each support member contacts an upper side of the overlying roof members. Receiving portions formed at outside lower ends of the connecting members are in close proximity to side edges of the enclosed part of the roof and receive one of the support members.

Abstract: A roof apparatus includes a plurality of light collecting members, each having a pair of left and right vertical members, an upper horizontal member, a lower horizontal member, and a transparent plate. The upper horizontal members are disposed at a ridge side end of the vertical members, the lower horizontal members are disposed at an eaves side end of the vertical members, and the transparent plate is disposed on the inner periphery of the vertical members, the upper horizontal member, and the lower horizontal member. The light collecting members are connected in a slope direction of the roof, and the lower horizontal member has a transparent plate holding piece, a transparent plate contact wall, and a cover piece. The transparent plate holding piece is adapted to hold an eaves side end of the transparent plate. The transparent plate contact wall has a thickness which is smaller than the thickness of the transparent plate.
