To eliminate queer appearance of a photovoltaic generating apparatus mounted on a roof material, in a roof structure having photovoltaic generating panels incorporated therein, to produce stereoscopic effect rich in fanciness on the roof, and to safely and efficiently carry out construction work of the panel.
There is provided a roof structure having photovoltaic generating panels 6 incorporated therein. Longitudinal bars 4 are secured on the upper surface of a roof substrate 3, and lateral bars 5 are secured over the longitudinal bars on which the panels 6 are secured. In this structure, out of the panels 6 adjacently arranged on the roof at an upper portion and lower portion of the lateral bar 5, a photovoltaic generating panel 6a arranged on the upper side has its lower edge positioned above the upper edge of a photovoltaic generating panel 6b arranged on the lower side, whereby a step portion is formed.
