A plurality of drain holes 43 are formed at the bottom of the concave line 41 at regular intervals, and rainwater flowing through the concave line 41 is discharged to the farmland. The rainwater receiving plate 4 of the second example is particularly suitable when there is a lot of rain. By providing a plurality of irregularities along the inclination direction, the rainwater flowing on the surface of the rainwater receiving plate 4 is surely discharged from the drain hole 43. Configured to be discharged.

  Furthermore, as shown in FIG. 4, the rainwater receiving plate 4 preferably has a partition member 44 in the recess 41. When there is a lot of rainfall, such as during heavy rains, the falling water from the solar panel 2 may be biased due to a slight inclination of the solar panel 2 or the gantry 3. At that time, the concave ridge 41 is divided into a plurality of parts, so that the rainwater that flows unevenly to the rainwater receiving plate 4 and flows through the concave ridge 41 is blocked by the partition member 44 and overflows to the adjacent concave ridge 41. This makes it possible to drain rainwater evenly to farmland. The rainwater receiving plate 4 shown in FIGS. 1 and 2 is the rainwater receiving plate 4 of the second example shown in FIG.

  Next, a third example of the rainwater receiving plate 4 according to the present invention will be described with reference to FIG. The same components as those in the second example are denoted by the same reference numerals, and differences from the second example will be mainly described below. As shown in FIG. 5, the rainwater receiving plate 4 of the third example is configured such that a plate-like body is continuously bent at a right angle, and a plurality of concave stripes 41 and convex stripes 42 are alternately formed at regular intervals.
