Embodiment Construction

[0046] In the present invention, the same names and the same reference numerals are assigned to structural elements showing the same or similar effects.

[0047] Hereinafter, the solar reflection system of the first embodiment of the present invention will be described in detail.

[0048] Such as figure 1 As shown, the solar reflection system 1 of the first embodiment of the present invention includes a double-sided light-receiving solar cell module M, a frame F and a reflective layer 10 .

[0049] The double-side light-receiving solar cell module M can be constructed by known techniques, and the structure of the double-side light-receiving type solar cell module M itself is not the gist of the present invention, so its description is omitted.

[0050] The double-sided light-receiving solar cell modules M are arranged on the frame F in an oblique manner. The frame F includes: a first frame F1, used to support the edge of the double-sided light-receiving solar cell module M; ...

Abstract

A solar light reflecting system is characterized by including a double-sided light-receiving solar cell module provided on a roof; a frame for arranging the double-sided light-receiving solar cell module provided on the roof; and a reflective layer which is positioned on the rear side of the double-sided light-receiving solar cell module provided on the roof and which is arranged on the bottom surface of the roof, wherein the reflective layer has heat insulation and waterproof functions, and conducts diffuse reflection of 380-1100nm sunlight with the wavelength range of 85% or more that avoidsthe double-sided light-receiving solar cell module to directly enter the bottom surface of the roof or that passes through the double-sided light-receiving solar cell module to enter the bottom surface of the roof to the rear side of the double-sided light-receiving solar cell module.

Description

technical field [0001] This invention relates to solar reflecting systems. Background technique [0002] Generally, solar modules generate power only by receiving light from the front, so there is a limit to increasing power generation. Recently, a double-sided light-receiving type solar cell has been developed that can receive light on both the front surface and the rear surface to generate electricity. [0003] Korean published patent (10-2018-0002015) discloses a backsheet for solar modules to increase the power generation of double-sided light-receiving solar cells. [0004] However, although the backsheet for solar modules has excellent properties, the power generation of double-sided light-receiving solar cells inevitably changes depending on the state of the bottom surface that reflects sunlight. [0005] For example, depending on the situation where the bottom surface is soil, the bottom surface is paved with concrete, the bottom surface is painted with white paint...
