<p>PROBLEM TO BE SOLVED: To provide a solar battery module which is not deformed even if wind pressure or another external force is applied thereto, does not bring about problems in terms of disaster prevention in case of a fire, and contributes to effective utilization of resources. SOLUTION: The solar battery module is constituted of a solar battery panel 11 and a heat insulating member 12 arranged on a rear surface of the solar battery panel 11, wherein the heat insulating member 12 is formed of lightweight concrete containing expanded resin beads. Further, 50 vol.% or more of the expanded resin beads contained in the lightweight concrete are formed of recycled expanded resin beads which are prepared from recycled resin foam waste.</p> |
