Abstract:
PROBLEM TO BE SOLVED: To provide a roof with solar battery capable of minimizing the difference in illuminance between a pair of roof surfaces and ensuring the light receiving surface without remarkably increasing the height of a building. SOLUTION: A plurality of flat solar battery panels 20 is arranged on a plurality of roof surfaces 13-15. One adjacent roof surface 15 is extended obliquely down from a boundary line 11, and the gradient of the roof surface 15 is set more gentle than that of the roof surface 14. According to this, the light receiving area of the roof surface 15 can be sufficiently ensured even if the roof surface 15 is arranged on the north side. When the right receiving area of the roof surface 15 arranged on the north side with the boundary line 11 of the roof surfaces 14 and 15 as the ridge is set larger than that of the roof surface 14 arranged on the south side, the difference in illuminance between the roof surfaces 14 and 15 is minimized, and the light receiving area can be sufficiently ensured without increasing the height of the building 1.
