Method for increasing power generation efficiency by solar panels, materials for agriculture or photovoltaics, weed control materials and agricultural multi-materials composed thereof, and method for cultivating crops using the materials

Abstract

To provide an agricultural or photovoltaic material capable of enhancing photovoltaic power generation efficiency in a field photovoltaic power generation solar sharing agricultural method and the like, suppressing light deterioration when the material is used as a weed-proof sheet, and assisting growth of crops by high reflectivity when the material is used as a mulch material.SOLUTION: An agricultural or photovoltaic material 1 is configured so that, on a surface of a substrate 2, gravel-shaped reflectors 31 are arranged in a layer state. The material is configured so that the plurality of gravel-shaped reflectors 31 provided on the surface of the substrate 2 reflects light radiated from an upper side of the substrate, so as to radiate the reflectance to an object which exists above the substrate. The reflectance is radiated to a rear surface of a double surface power generation type solar panel and crops, thereby increasing a power generation amount of the solar panel and promoting growth of the crops.SELECTED DRAWING: Figure 1
