<P>PROBLEM TO BE SOLVED: To provide a structure capable of selecting the presence or absence of shading in a structure that shade crops through solar cells. <P>SOLUTION: In a structure for cultivating crops inside a cultivating house 100, a sheet 130 with flexible solar cells is located. The seat 130 has a portion without solar cells and is configured to be movable above a cultivating bed 121 by winding and rewinding apparatuses 131, 132. In shading crops, the sheet 130 is moved so that the solar cells are positioned above the crops for shading and photovoltaic power generation. In applying sunshine to crops, the sheet 130 is moved to prevent shading by the solar cells. <P>COPYRIGHT: (C)2012,JPO&INPIT |
