Description

[0001] The present invention relates to a photovoltaic (PV) module fixing device, a building-integrated photovoltaic power generation system incorporating the same, a method of constructing a photovoltaic module,

FIELD OF THE INVENTION The present invention relates to a PV module fixing device, a building integrated photovoltaic power generation system incorporating the same, and a method of constructing a PV monolithic building system.

Building Integrated Photovoltaic System (BIPV), which is a building integrated photovoltaic system (BIPV module), is constructed by building PV modules (photovoltaic modules, PV modules) into buildings and increasing their value It is a concept to promote and activate the PV system.

At the same time as BIPV produces electrical energy, it is installed on the outer walls of buildings such as roofs, facades, blinds, and solar collectors.

The construction of the PV module is largely divided into a glass to glass (G2G) system that is coupled between windows and windows, and a glass to tedlar system that is coupled between windows and walls. To construct the PV module, join the frame around the PV (Photovoltaic) module and secure the frame to the building. In some cases, the PV module may be attached to the building with silicon or the like while the frame is omitted.

Since the frame is coupled in the form of wrapping around the PV module, a step is formed between the surface of the PV module and the front surface of the frame by the thickness of the frame. If foreign substances such as dust or snow accumulate on the bottom of the PV module, the solar cell of the PV module is covered. Therefore, the solar light absorption amount of the PV module is significantly lowered.

Also, since the frame is attached to the PV module and the frame is fixed to the building, installation and construction are somewhat complicated. The PV modules installed in this way can not be disconnected in case of abnormal output, which leads to inconveniences in the inspection and maintenance.

On the other hand, when BIPV was installed on the outer wall of the building, it was not in harmony with the building and did not receive much choice from the architects.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Like parts are designated with like reference numerals throughout the specification.

The PV module fixing apparatus according to the embodiment of the present invention can be applied to a PV module with integrated building type which is an embodiment of the present invention. Hereinafter, a PV module with a PV module fixing device will be described.

A building-integrated photovoltaic power generation system according to an embodiment of the present invention will now be described with reference to FIGS. 1 to 5. FIG.

1 is an exploded view of FIG. 1, FIG. 3 is a side view of FIG. 1, and FIG. 4 is an enlarged view of a portion A of FIG. 3 And Fig. 5 is an enlarged view of a portion B in Fig.

Referring to FIGS. 1 to 5, a building integrated photovoltaic power generation system 1 according to the present embodiment includes a PV module 10 and a PV module fixing device 20.

The PV module 10 absorbs sunlight to produce electricity. The detailed structure of the PV module 10 can be applied to the well-known structure of the PV module, and a detailed description of the structure will be omitted.

The PV module fixing device 20 is fixed to a building to support the PV module 10 and includes a base 21, a bracket 22 and a supporting member 23. [

The base 21 has a predetermined width, and an upper flange 211a is formed on the upper side and a lower flange 211b is formed on the lower side. The upper flange 211a and the lower flange 211b are formed along the outer wall of the building.
The module fixing device 20 can be fixed to the outer wall of the building by fixing means such as bolts or rivets passing through the upper flange 211a and the lower flange 211b. The upper flange 211a and the lower flange 211b may be fixed to the window in a welding manner. For example, the PV module fixing device 20 is arranged in the vertical and horizontal directions of the building. The PV module securing apparatus 20 arranged in the left-right direction is arranged in contact with each other and the PV module securing apparatus 20 arranged in the up-and-down direction is disposed on the upper side of the upper side of the PV module securing apparatus 20 The flange 211a and the lower flange 211b are arranged so as to overlap with each other and are fixed by fixing means.

One surface 21a of the base 21 has a first inclined portion 21b and a second inclined portion 21c. The first inclined portion 21b abuts against the PV module 10 and is inclined so that the PV module 10 can be inclined. The inclination of the first inclined portion 21b on one surface 21a of the base 21 may be 5 to 45 degrees with respect to the vertical wall surface. Preferably 30 degrees to 33 degrees. If the inclination angle of the base 21 is less than 5 degrees or more than 45 degrees, the incidence angle of sunlight is not easy and the output of the PV module 10 may be lowered. In addition, the inclination of the first inclined portion 21b on one side 21a of the base 21 may vary according to the incidence angle according to the altitude of the sun.
The second inclined portion 21c connects the first inclined portion 21b and the lower flange 211b.

Table 1 and Table 2 below show the test results showing the output of the PV module according to the inclination of one side of the base.

In Table 1 below, one side of the base is parallel to the wall surface, and one side of the base for the wall is inclined. The above experiment was carried out from July to December by installing it on the outer wall of the building.

In the summer (July to October) where the altitude of the sun is high, there is a large difference in the output of the PV module (10) for the general module and the wall because the inclination of the module for the wall depends on the altitude of the sun . As shown in the above Table 1 and Table 2, monthly total leakage power generation capacity comparison results show that the wall module is 6.36% higher monthly than the general module.

The inside of the base 21 is empty and an opening hole 212 is formed in the first opening 21b on one side 21a to support the edge of the PV module 10. A side surface 213 is formed in a side surface of the base 21 and a plurality of heat dissipation holes 214 are formed in the second inclined portion 211b.
Here, when the PV module 10 is disposed on one side, the opening hole 212 is covered by the PV module 10, and the side hole 213 and the heat dissipation hole 214 are not covered. The heat generated in the PV module 10 may be discharged to the outside of the base 21 through the side openings 213 and the heat dissipation holes 214 through the openings 212. [ In other words, The PV module 10, which generates heat as the air circulates through the opening hole 212, the side hole 213, and the heat dissipation hole 214, may have a heat radiation effect. The power generation efficiency can be further improved by the heat radiation effect.

Meanwhile, a cable (not shown) for connecting the PV module 10, the junction box (not shown), the inverter and the like can pass through the hole 213.

Although the base 21 is shown in a rectangular shape in FIGS. 1 and 2, it may be variously changed depending on the structure of the building and its installation position.

An angle adjusting device (not shown) is installed between the base 21 and the building or between the base 21 and the PV module 10, although the description has been made that the PV module 10 is inclined at one side of the base 21 So that the inclination of the PV module 10 can be adjusted.

The bracket 22 contacts one side (upper end) of the PV module 10 at one side (upper end) of the base 21 and the support member 23 contacts the other end (lower end) of the PV module 10 at the other side Touch the other side (bottom). The bracket 22 and the support member 23 are spaced apart from each other along the longitudinal direction of the base 21.

A plurality of brackets (22) are formed, and a plurality of brackets (22) are arranged with an interval in the longitudinal direction of the base (21). A plurality of support members 23 are also formed and the support members 23 are arranged at intervals in the longitudinal direction of the base 21 in a state of facing the respective brackets 22.

1 and 2, the bracket 22 and the support member 23 are positioned at both ends of the base 21. However, the bracket 22 and the support member 23 may be located at the center of the base 21. [ The number of the brackets 22 and the support members 23 may vary depending on the lengths of the base 21 and the PV module 10. [

The bracket 22 abuts on the upper side of the PV module 10 and the end portion 221 of the bracket 22 is bent in the direction of the supporting member 23 to grasp the upper edge of the PV module 10. The end portion 221 grasps the edge of the PV module 10 without overlapping with the solar cell (not shown) of the PV module 10. The bent portion of the bracket 22 has an elastic force. The bracket 22 presses the PV module 10 in the direction of one surface of the base 21 so that it can be closely contacted.

The support member 23 is supported on the lower side of the PV module 10 and the end portion 231 is bent in the direction of the bracket 22 to elastically grip the lower edge of the PV module 10. A large amount of snow, dust, etc. are not accumulated on the lower side of the PV module 10 because the support members 23 are formed at intervals. Therefore, there is no problem that the efficiency of the solar cell is lowered due to accumulation of snow, dust, and the like.

The bracket 22 and the support member 23 are integrally formed when the base 21 is molded. However, the bracket 22 and the support member 23 may be fixed to one surface of the base 21 by means of rivets, bolts, welding, or the like.

The PV module 10 can be easily installed on the outer wall of the building by the PV module fixing device 20 and the PV module 10 is fixed by the holding of the bracket 22 and the support member 23, The PV module 10 can be easily separated from the PV module fixing device 20 in the event of an output abnormality, thereby facilitating maintenance. Also, since the support member 23 supports the PV module 10 without wrapping it, dust, snow, and the like are not accumulated on the front surface of the PV module 10.

On the other hand, various colors can be painted on the surface of the fixing device 20 according to the color of the building. By the coloring of the fixing device 20, the building-integrated photovoltaic power generation system can be harmonized with the building to be installed naturally.

Still another embodiment of the present invention has most of the components of the embodiment described with reference to Figs. However, as shown in Figs. 6 and 7, the structure of the support member 23 is different. The end portion 231 of the support member 23 according to the present embodiment is not bent. At the end portion 231, a protrusion 232 protruding upward to catch the lower edge of the PV module 10 is formed. Since the upper surface of the projection 232 is inclined, snow, dust and the like can flow down without accumulation. Therefore, it is possible to prevent problems caused by accumulation of snow, dust, and the like. However, the protrusion 232 may be omitted. In other respects, the configuration of the embodiment of Figs. 1 to 5 may be applied as it is.

Yet another embodiment of the present invention has most of the components of the embodiment described with reference to Figs. However, as shown in Figs. 8 and 9, the buffer member 30 is further included. The cushioning member 30 is disposed at the bracket 22 and the support member 23 where the PV module 10 contacts. The cushioning member (30) fixes the PV module (10) so as not to slip, and elastically supports the PV module (10). Also, the surface of the PV module 10 is prevented from being damaged by the impact generated by the contact between the PV module 10, the bracket 22, and the support member 23. In other respects, the configuration of the embodiment of Figs. 1 to 7 can be applied as it is.

Yet another embodiment of the present invention has most of the components of the embodiment described with reference to Figs. However, as shown in FIGS. 10 and 11, it may further include the departure-avoiding portion 40. The departure prevention portion 40 prevents the PV module 10 from escaping from the support member 23. The release preventing portion 40 includes a housing 41, a spring 42, and a ball 43.

The support member 23 has a hole 23a penetrating through the upper and lower portions thereof and a housing 41 is coupled to the hole 23a.

The housing 41 is screwed to the support member 23. The inside of the housing 41 is empty and one side is open. One surface of the housing 41 is located on the same plane as the upper surface of the support member 23. So that one surface of the housing 41 is not caught by the PV module 10 placed on the support member 23.

A spring 42 is disposed inside the housing 41.

The ball 43 is disposed inside the housing 41 and is supported by the spring 42. At least a part of the ball 43 is protruded outside the housing 41 by the elastic force of the spring 42. The protruding portion of the ball 43 is brought into contact with the side surface of the PV module 10 so that the PE module 10 is not separated from the support member 23.

On the other hand, the opening diameter of one surface of the housing 41 is formed to be smaller than the diameter of the ball 43 so that the ball 43 does not separate from the housing 41. Thus, the ball 43 can be caught in the opening of the housing 41. When the ball 43 is pressed, the spring 42 can be compressed and flow into the housing 41. The engagement of the PV module 10 is released and the PV module 10 can be separated from the support member 23. In other respects, the configuration of the embodiment of Figs. 1 to 9 can be applied as it is.

Yet another embodiment of the present invention has most of the components of the embodiment described with reference to Figs. However, as shown in Fig. 12, the length of the bracket 22 is the same as the length of the base 21 in the longitudinal direction. The bracket 22 abuts the upper end of the PV module 10 by more than 1/2. The support member 23 is also formed so as to correspond to the bracket 22. The supporting member 23 contacts with the lower end of the PV module 10 by at least 1/2.

However, the bracket 22 and the support member 23 may be formed to be smaller than the length of the base 21 in the longitudinal direction. 12, the bracket 22 and the support member 23 correspond to each other, but any one of the bracket 22 and the support member 23 is the same as the longitudinal length of the base 21 And the other may be arranged in plural and arranged along the longitudinal direction of the base 21.

In other respects, the configuration of the embodiment of Figs. 1 to 11 may be applied as it is.

Yet another embodiment of the present invention has most of the components of the embodiment described with reference to Figs. However, an adhesive may be applied between one side of the PV module 10 and the support member 23 to fix the PV module 10. The other side of the PV module 10 can be more firmly fixed to the PV module fixing device 20 by the adhesive and the supporting member 23. [ In other respects, the configuration of the embodiment of Figs. 1 to 12 may be applied as it is.

Next, a method of constructing a PV system with integrated buildings will be described.

Referring again to FIGS. 1 to 3, the method for constructing a PV module of a building incorporates a PV module fixing device preparation step, a PV module placement step, and a fixing device mounting step.
