In general, a louver window refers to a window in which a plurality of shading wings installed horizontally within a frame are spaced apart along the vertical direction, and the shading wings are tilted through manipulation of a lever to provide light and shading.

Regarding such a louver window, an application has previously been filed under Republic of Korea Patent Publication No. 2016-0131565 (publication date 2016.11.16).

Meanwhile, due to recent environmental pollution and fossil energy depletion issues, the development of environmentally friendly alternative energy sources and future energy diversification have emerged as international issues.

In particular, in accordance with the United Nations Framework Convention on Climate Change (1994), the Kyoto Protocol (1997), and the Paris Agreement (2015), countries around the world are reorganizing new and renewable energy-related laws and policies to actively supply renewable energy in accordance with the mid- to long-term greenhouse gas emission reduction obligations. is being promoted. In particular, in environments where it is difficult to increase the rate of new and renewable energy generation, such as urban areas (solar power generation, a representative new and renewable energy power source, requires large amounts of land), the importance/effectiveness of solar power generation systems attached to the exterior walls of buildings is increasing. This is the situation.

Against this background, solar cells utilizing solar energy are attracting attention as a powerful alternative energy source for the future, and as solar cells become cheaper, the size of the related global market is rapidly increasing.

However, solar power generation using such solar cells is mostly installed through a separate structure on the roof of a house or the railing of an apartment veranda. Therefore, additional installation costs are required for solar power generation, and the aesthetics of the building may be damaged by these solar power generation structures.

In addition, the conventional railing-type solar power generation method has problems such as the structure protruding outside the building, which may cause safety problems, and is usually installed at a fixed angle, causing light pollution to adjacent buildings.

In order to solve this problem, a louver assembly equipped with solar cell panels (solar modules) that can be more easily connected in series without the wiring of multiple solar cell modules being exposed to the outside is patented in Korea Registered Patent No. 10- It is disclosed through No. 2247681, “Louver assembly on which a solar cell panel can be mounted.”

Looking at the configuration of the prior art with reference to FIGS. 1 and 2, the solar cell panel unit 100 has a pair of terminal units 111 provided at both ends, and a pair of terminal units to be electrically connected to each terminal unit. A plurality of solar cell module units 10 including a first electrode terminal 270 and a pair of first caps 200 mounted on the solar cell panel unit to surround each first electrode terminal; a plurality of second caps 30 including a second electrode terminal 310 to be electrically connected to the first electrode terminal and a terminal housing 312 surrounding at least a portion of the second electrode terminal; A frame portion 50 on which a plurality of second caps are each rotatably mounted along the longitudinal direction; When a plurality of solar cell module units 10 are mounted within the frame unit, a pair of third electrode terminals for electrically connecting the second electrode terminals 310 of two adjacent solar cell module units 10 are provided. The solar cell panel unit 100 includes a solar cell panel 110 provided to produce electricity and a blade frame 120 on which the solar cell panel is mounted, and the solar cell panel 110 includes a solar cell panel 110 configured to produce electricity. , glass, one or more encapsulants, solar cells, and a backsheet.

However, the above-described prior art uses a first gasket, a first electrode terminal, a first cap, a second electrode terminal, and a terminal housing to electrically and mechanically connect the frame portion 50 and the solar cell module portion 10. , the assembly process was complicated because a large number of components, including the second cap and third electrode terminal, had to be organically combined with each other.

This caused the problem of low productivity as it took a lot of time to assemble the product, and there was a problem of increased manufacturing costs due to the use of multiple parts and increased risks due to parts management.

In addition, the prior art used three electrode terminals, so a large number of electrical contacts were unavoidable, which caused a problem in that the connection resistance between electrodes increased, causing a decrease in solar power generation efficiency.

Above all, according to the national standard for solar power generation modules installed on the exterior wall of a building (KS C 8577, the solar power generation system louver of the present invention corresponds to this), the insulation resistance of the entire system louver assembly is stipulated to be above a certain level. As the number of electrical contacts increases, the risk of leakage current increases, and when leakage current occurs, the probability of safety accidents such as fire and electric shock increases rapidly.
