Abstract

The existing solar power generation panel installed on the roof of a smart farm has problems that an amount of light transmitted into the greenhouse is significantly reduced and the transmitted light is also not uniform, and thus an area where the solar power generation panels are installed is shaded and a shadow occurs. For these reasons, an installation distribution rate of solar power generation panels installed on the roofs of smart farms is very low. A solar power generation system for smart farms includes a three-dimensional (3D) optical filter window with a function of selectively transmitting light of wavelengths applicable to smart farms, and a solar power generation module provided to protrude above an optical filter of the optical filter window to increase solar power use efficiency. Since shading occurs when a solar power generation panel is used in a smart farm to affect cultivation, there is a problem in that the solar power generation panel cannot be used on the roof of a smart farm. However, according to the above-described configuration of the present invention, the optical filter window equipped with a dichroic light filter is used to solve this problem so that there is an effect of operating a smart farm more economically.

First claim

What is claimed is:

1 . A solar power generation system provided with a three-dimensional (3D)-shaped optical filter window for a smart farm, the solar power generation system comprising:
an optical filter window provided on a roof of a smart farm and configured to transmit light of selected wavelengths and reflect light of other wavelengths; and a solar power generation module provided to protrude above an optical filter of the optical filter along the edge of the optical filter window, wherein a horizontal or vertical folding portion is introduced into the optical filter window, and the optical filter window uses the reflected light of other wavelengths for power generation in the solar power generation module provided to protrude above the optical filter of the optical filter window.

2 . A solar power generation system provided with a three-dimensional (3D)-shaped optical filter window for a smart farm, the solar power generation system comprising:
an optical filter window provided on a roof of a smart farm and configured to transmit light of selected wavelengths and reflect light of other wavelengths; and a solar power generation module provided to protrude above an optical filter of the optical filter along the edge of the optical filter window, wherein a dichroic optical filter has a 3D shape having various shapes such as waves that are the same or that narrow and widen in a horizontal or vertical direction using a flexible substrate, and thus constant transmission of sunlight of selected wavelengths required for smart farm cultivation is maintained, and a direction in which light of other wavelengths is reflected is directed to the solar power generation module provided to protrude above the optical filter of the optical filter window so that solar power generation efficiency of the solar power generation module is improved.

3 . A solar power generation system provided with a three-dimensional (3D)-shaped optical filter window for a smart farm, the solar power generation system comprising:
an optical filter window provided on a roof of a smart farm and configured to transmit light of selected wavelengths and reflect light of other wavelengths; and a solar power generation module provided to protrude above an optical filter of the optical filter along the edge of the optical filter window, wherein cut lines are formed on the optical filter window in a predetermined pattern and the optical filter window is folded and formed in a 3D shape of a triangular or quadrangular shape, and thus constant transmission of sunlight of selected wavelengths required for smart farm cultivation is maintained, and a direction in which light of other wavelengths is reflected is directed to the solar power generation module provided to protrude above the optical filter of the optical filter window so that solar power generation efficiency of the solar power generation module is improved.

4 . The solar power generation system of claim 1 , wherein the optical filter window includes a dichroic optical filter.

5 . The solar power generation system of claim 2 , wherein the optical filter window includes a dichroic optical filter.

6 . The solar power generation system of claim 3 , wherein the optical filter window includes a dichroic optical filter.
