The building-integrated photovoltaic module of the present invention is configured as shown in FIG. 1 and is installed on the roofs of houses and apartments, buildings and factories by being combined in front and rear, left and right, and configured to perform self-generation by collecting sunlight. As a collecting device, it is configured to be easily coupled to a sloped roof.

In the building-integrated photovoltaic module (BIPV module) of the present invention, a plurality of solar cells 10 provided between frames coupled to four surfaces collect sunlight.

Here, the BIPV system (Building Integrated Photovoltaic System) is a power generation system that uses solar light by installing panels on the building envelope. It is also used as a design element to reduce construction costs and increase the value of buildings.

In addition, the building-integrated photovoltaic module is wired to facilitate electrical connection of solar cells, and is a module compressed with fillers and glass to protect it from the external environment. occurs, so a plurality is connected in series for a desired voltage or current value.

In this case, since the solar cell 10 has the same basic concept as a small photovoltaic module used in battlefield electronics, it will be collectively referred to as the solar cell 10 hereinafter.

In particular, in the present invention, it should be configured to simultaneously satisfy lighting and power generation efficiency due to the specificity of the installation location adjacent to the building, such as a roof. To this end, in the present invention, a high-efficiency back contact cell (IBC cell; Integrated Back Contact cell) is applied so that excellent lighting and high power generation efficiency can be satisfied at the same time.

Compared to the conventional front electrode cell, the back electrode cell applied to the present invention can improve the light penetration of sunlight incident from the front since the electrode connecting the individual cells is located on the rear.

In addition, the applicant of the present application has developed a technique for significantly spaced apart cells compared to the prior art in order to increase the lighting properties, and applied this to the present invention.

That is, the front electrode cell has a cell interval of only about 2 mm, and when used as it is, almost no light is transmitted to the rear side, so light penetration is extremely deteriorated.

To this end, in the present invention, a high-efficiency solar cell is used, and at the same time, the electrode is placed on the back side to minimize the area where sunlight is blocked by the electrode, and the distance between each cell is about 20 to 50 mm, so that lighting and power generation efficiency are simultaneously achieved. configured to satisfy.

On the other hand, the building-integrated photovoltaic module (BIPV module) to which the back electrode cell of the present invention is applied is composed of a frame that can be connected in front and rear, left and right, and is detachably coupled to the roof, and a plurality of solar cells 10 provided between the frames collect sunlight.

The building-integrated photovoltaic module is connected to a micro-inverter (not shown) with wires to convert the collected sunlight into electrical energy. The micro-inverter installed in the present invention is used for individual or multiple unit installations. , Since these individual unit modules have low voltage, it is impossible to use the existing residential inverter that controls the power of 3KW, and a micro inverter, which is a voltage-to-current converter implemented to control the power of 300 to 400W, which is a small capacity, is used. .

At this time, since the power output varies depending on the installation state of the building-integrated photovoltaic module, the micro-inverter of the present invention is individually installed within a range of 300 to 400W in power output per unit module.

The building-integrated photovoltaic module of the present invention is composed of four frames that surround a plurality of solar cells 10 in front and rear and left and right, and by these frames, a plurality of modules are easily combined in front and rear and left and right to be installed on the roof.

A front frame 20 and a rear frame 30 are coupled to the front and rear surfaces of the solar cell 10, a left frame 40 and a right frame 50 are coupled to the left and right sides of the solar cell 10, respectively, and a cover frame to the right frame 50. 60 is combined.

A module in which solar cells 10 coupled to the inside are configured as one, or a larger number of solar cells 10 are combined in front, back, left and right. It can be cut by adding or subtracting the length as needed so that it can be applied to.

The front frame 20 has a stepped support part 21 formed in an 'a' shape in the longitudinal direction on the front surface, and a plurality of installation holes 22 for fixing the modules coupled in the front and rear to each other or to the roof in the support part 21 is formed, and a fixing groove 23 is formed in the longitudinal direction on the rear side of the installation hole 22.

As shown in FIG. 2, elastic parts 41 and 51 are respectively formed on the upper sides of the left frame 40 and the right frame 50, and a solar cell 10 is inserted together with a protective cover 11 between the elastic parts 41 and 51 and the frame. It is fixed.

In addition, as shown in FIG. 3, a cover frame 60 is coupled to the right frame 50 by a plurality of bolts 62, and an elastic part 61 protrudes upward from the module on the upper side of the cover frame 60 in a substantially 'c' shape. are formed symmetrically.

In this way, the building-integrated solar module of the present invention composed of four frames coupled to the outside of the solar cell 10 can be coupled back and forth by connecting the front frame 20 and the rear frame 30 to each other as shown in FIGS. 4 and 5 .

That is, by inserting and fixing the fixing part 31 of the rear frame 30 into the fixing groove 23 of the front frame 20, a plurality of modules can be combined in front and rear. will have the same height.

Wires drawn from the plurality of solar cells 10 pass through the lower space of the coupled support 21 and are connected to the micro inverter, thereby preventing the wires from being exposed to the outside and impairing aesthetics.

As described above, the plurality of BIP modules coupled back and forth can be combined left and right by connecting the left frame 40 and the cover frame 60 to each other as shown in FIGS. 6 and 7 again.

That is, by fixing the elastic part 61 of the cover frame 60 on the upper side of the left frame 40, a plurality of modules can be coupled left and right. It is integrally coupled to the roof material constituting the roof using a coupling means.

On the other hand, as shown in FIG. 8, by configuring the building-integrated photovoltaic module of the present invention to replace the coupling plate 70, which is a roofing material, it is possible to more easily construct and maintain the module installed on the roof.

To this end, a plurality of coupling portions 71 formed in a '┏' shape are formed on the left side of the coupling plate 70, and a second coupling portion 72 formed in a ring shape is formed on the right side.

The coupling plate 70 is a roof material coupled to the roof in plurality, and is connected by fixing the second coupling portion 72 of the other coupling plate 70 to the upper side of the first coupling portion 71 .

By combining the building-integrated photovoltaic module of the present invention between the coupling plates 70 to replace the roof material, not only can solar power be generated, but also the module installed on the roof can be more easily constructed.

As a result, a plurality of modules can be connected left and right.

The plurality of modules coupled in this way can be connected back and forth by attaching another coupling plate 70 to the front and rear surfaces of the coupling plate 70 and using the fixing groove 23 of the front frame 20 and the fixing part 31 of the rear frame 30.

In addition, although one BIP module is shown fixed between the two coupling plates 70 in the drawing, it is not limited thereto, and a plurality of BIP modules are connected left and right between the two coupling plates 70 as shown in FIG. It goes without saying that a roof may be formed.

Therefore, a plurality of building-integrated photovoltaic modules are integrally coupled to the roof of a building by combining a plurality of modules front and rear, left and right, on the bonding plate 70 used as a roofing material.

The present invention can collect sunlight as much as possible to increase power generation efficiency by easily combining the building-integrated solar module to which the high-efficiency back electrode cell is applied in front and rear and left and right by a simple structure frame, as well as to increase the production cost and installation cost. can be saved, and there is no worry of failure, so maintenance is more easy.
