Description

Building Integrated Photovoltaic Module Assembly Having Externally Exposed Surface Washing Structure}

The present invention relates to a building-integrated solar module assembly, and more specifically, to a building-integrated solar module assembly that includes a configuration that allows easy cleaning of externally exposed surfaces.

Solar power generation is a power generation method that directly converts sunlight into electrical energy using multiple solar modules. It is free from air pollution, noise, heat, and vibration, is easy to maintain, and has a long lifespan, making it a new generation method. It is gaining attention as an energy source. Because these solar power generation devices are capable of small-scale power generation, they were mainly operated by the government or local governments in the past, but individuals and companies are gradually constructing and operating solar power generation devices.

However, due to the realistic problem of limited effective space in urban areas where many people live, many solar power generation devices are constructed and installed on the roofs of buildings or rooftops. Recently, solar power generation devices have evolved from simply being used for power generation to BIPV (Building Integrated Photovoltaic System) so that they can also function as building exterior materials. Representative examples include laying a frame along the bottom of the rooftop. There is a method of installing multiple solar panels.

However, in the case of the BIPV solar power generation method, multiple solar cell panels are installed along the roof, rooftop, and walls of the building, so when it rains, rainwater flowing along the surface of the solar cell panel flows concentrated in a specific direction on the rooftop. , During this process, serious rainwater stagnation occurred in certain areas. In this case, stagnant rainwater destroyed the waterproofing layer or penetrated into the concrete surface, causing the building to lose its waterproofing ability.

To solve this problem, as shown in FIG. 1, a structure in which drainage channels 3 and 6 are installed inside the BIPV solar cell panel assembly to drain rainwater to the outside was developed.

However, in the case of the BIPV solar cell panel assembly according to the prior art, although it is provided with drainage channels 3 and 6 inside, there is a problem in that foreign substances are adsorbed or deposited on the surface of the solar cell panel exposed to the outside, reducing power generation efficiency. .

To solve this problem, cleaning work is performed using cranes, but there is a problem of high maintenance costs, such as the cost of mobilizing crane equipment and the time and manpower required for cleaning work.

Therefore, there is a need for a technology that can solve the problems caused by the prior art mentioned above.
