A solar power generation system that performs solar power generation by mounting it on the roof of a house includes a solar power generation module 1 whose minimum unit is illustrated in FIG. The solar power generation module 1 is obtained by laminating a solar cell with tempered glass to have weather resistance. This photovoltaic power generation module 1 constitutes a photovoltaic power generation array 3 shown in FIG. 5, which is an assembly in which a predetermined number of photovoltaic modules are connected in series and parallel to obtain a specified voltage. As shown in FIG. 6, the photovoltaic array 3 has rail members 9 arranged side by side on a waterproof sheet 7 laid on a roof panel 5, and the individual photovoltaic modules 1 are fixed to the rail members 9 to make the roof.

[0003] However, in the above-mentioned conventional solar power generation roof structure, the width of the solar power generation module and the roof panel (width in the longitudinal direction of the purlin) are formed to be the same. Since the mounting position of the rail material did not match the joint part of the roof panel, the rail material could not be fixed to the rafters at the joint part, so the rail material had to be directly nailed to the panel surface of the roof panel It was also assumed that this would not be the case, which was a factor in reducing the mounting strength of the photovoltaic power generation array. Further, even when the width of the photovoltaic module and the roof panel are formed to be the same, when the joint portion 13 of the roof panel does not match the mounting position of the rail member 9 as shown in FIG. Has a problem that the mounting strength of the photovoltaic power generation array is reduced. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a photovoltaic power generation roof structure capable of mounting a photovoltaic power generation array on a roof panel with sufficient mounting strength. [0004] To achieve the above object, a photovoltaic roof structure according to the present invention comprises: a roof panel forming a roof surface by joining a plurality of sheets in a longitudinal direction of a purlin; A rail material to be jointed to the joint portion of the roof panel in a joint direction, and the width in the longitudinal direction is formed to be the same as the width of the roof panel, and both ends in the width direction are placed on a pair of adjacent rail materials. Comprising a photovoltaic module , wherein the rail material sandwiches the joint of the joint portion
Position both sides at half pitch of the width of the roof panel
Fixed to the roof panel offset from each other,
The module is made up of adjacent thick sections formed on the rail material.
The joint between the solar power generation modules is filled with a dry type water stopping material . In the photovoltaic roof structure thus constructed, the roof panel and the photovoltaic module are formed to have the same width, the joints of the two coincide, and the rail material is fixed to the joint of the roof panel. The photovoltaic module can be supported at the joint of the roof panel. Both sides of the rail member are fixed to the roof panel while being shifted from each other at a half pitch of the roof panel width, so that interference of the driving and fixing means from both sides can be avoided. The joint between adjacent photovoltaic modules is filled with a dry-type water blocking material, and the surface of the photovoltaic module serves as a flow path for rainwater.
