Abstract

A reflector for solar thermal power generation includes a light collecting mirror attached to a self-supporting base material. The light collecting mirror includes at least: a flexible supporting body; and a light/heat reflective layer provided on at least one side of the supporting body. The self-supporting base material has any one of configurations A and B below: A: the base material includes a pair of metallic plates and an intermediate layer provided between the metallic plates, the intermediate layer being a layer having a hollow structure or a layer composed of a resin material; and B: the base material is composed of a resin material layer having a hollow structure.

Claims

1. A reflector for solar thermal power generation, comprising:

a light collecting mirror attached to a self-supporting base material, the light collecting mirror including at least;

a flexible supporting body; and

a light/heat reflective layer provided on at least one side of the supporting body, wherein

the self-supporting base material has any one of configurations A and B below;

A;

the base material includes a pair of metallic plates and an intermediate layer provided between the metallic plates, the intermediate layer being a layer having a honeycomb structure or a layer composed of a resin material; and

B;

the base material is composed of a resin material layer having a hollow structure.

2. The reflector for solar thermal power generation according to claim 1, wherein the hollow structure is a honeycomb structure or a bubble structure of resin foam.

3. The reflector for solar thermal power generation according to claim 1, wherein the base material has a curved shape.
