As shown in Figures 1 and 2, the solar power generation device 101 that prevents freezing by a heating cable according to an embodiment of the present invention may include panel closing caps 150 and 170.

The panel closing caps 150 and 170 may cover the border between the solar panels 110 to provide airtightness.

The panel closing caps 150 and 170 may be composed of a vertical panel closing cap 150 that airtightens the vertical gap of the plurality of solar panels 110 and a horizontal panel closing cap 170 that airtightens the horizontal gap. .

The vertical panel finishing cap 150 covers the upper edge of the solar panel 110 mounted on the panel support 130 along the longitudinal direction of the panel support 130 and can be airtight. It can be fixedly installed by being fastened to the panel support 130 by a fastening member.

Cap protrusions 151 may be formed on both sides of the vertical panel finishing cap 150 to support both edges of the solar panel 110, respectively.

The vertical panel closing cap 150 can be airtight by covering the vertical gap of the solar panels 110 located on both sides in the horizontal direction, and each solar panel 110 is installed on both sides of the bottom of the vertical panel closing cap 150. ) and the vertical panel finishing cap 150, and at the same time, a cable groove 152 in which a heating cable 155 for heating by heat is installed can be formed.

The horizontal panel finishing cap 170 can be airtight by covering the gap between the solar panels 110 that occurs between the strings ST in the vertical direction on the panel stand 130.

Here, if the vertical panel finishing cap 150 is continuous from one side of the roof to the other side in the vertical direction, the horizontal panel finishing cap 170 may be divided into multiple pieces and installed in the horizontal direction, and the horizontal panel finishing cap 170 may be installed horizontally. If it continues from one side of the roof to the other side in the direction, a plurality of vertical panel finishing caps 150 may be divided and installed in the vertical direction.

The horizontal panel finishing cap 170 may be installed by being inserted into and fixed to a gap between solar panels 110 arranged in the vertical direction.

A cap fitting portion 171 that is forcefully fitted between the solar panels 110 may be formed to protrude at the lower center of the horizontal panel finishing cap 170, and a cap fitting portion 171 may be formed at the lower portion of the cap fitting portion 171. ) is formed so that the cap fitting portion 171 is forcefully fitted between the solar panels 110, and the engaging portion is caught at the bottom of the solar panel 110, causing the solar panel ( It is possible to prevent the horizontal panel finishing cap 170 from coming off at 110).

On the bottom of both sides of the horizontal panel finishing cap 170, there is a heating cable 155 that seals and heats the space between the horizontal panel finishing cap 170 and the solar panel 110 airtightened by the horizontal panel finishing cap 170. Each of the installed cable grooves 172 may be formed.

At this time, the cable groove 172 is located at a position facing the panel frame 111 in the vertical panel finishing cap 170, so that the heating cable 155 heats the panel frame 111 to heat the solar panel 110. The ice occurring on the panel frame 111 can be removed by melting it with heat.

The heating cable 155 installed on the panel finishing caps 150 and 170 supports the solar panel by elastic force to ensure airtightness, and at the same time, when the solar panel 110 is shaken by vibration, the horizontal panel finishing cap 170 and the vertical panel The finishing cap 150 may directly contact the solar panel 110 to prevent the solar panel 110 from being damaged.

This heating cable 155 is installed entirely in the panel array, generates heat by electricity, and can prevent freezing by melting snow on the solar panel 110.

The heating cable 155 is installed on the panel finishing caps 150 and 170 to heat the solar panel 110, thereby melting and removing ice caused by snow.

Here, the panel frame 111, which protects the edge of the solar panel 110, is made of metal, so heat conduction to the outside occurs faster than other parts of the solar panel 110, so when it snows, the solar panel ( In 110), freezing occurs relatively more on the panel frame 111 than on other parts, and due to this freezing, snow cannot flow down from the solar panel 110, which is installed at an angle, and snow is prevented from flowing down from each part where the panel frame 111 is located. Because it accumulates, snow accumulates on the solar panel 110.

Accordingly, the heating cable 115 heats the edge portion of the solar panel 110, that is, the panel frame 111, thereby melting the ice occurring on the panel frame 111 and moving the snow on the solar panel 110 to the slope. By allowing it to flow downward, snow can be quickly removed.

Meanwhile, the heating cable 155 is installed on the horizontal panel finishing cap 170 and the vertical panel finishing cap 150 and are electrically connected to each other in series or parallel, or one heating cable 155 is connected to the horizontal panel finishing cap (155). 170) and the vertical panel finishing cap 150 can all be installed in the panel array in a zigzag shape.

The heating cable 155 may include a heating wire 155a that is heated by electricity, and an elastic sheath 155b made of an elastic material that surrounds the heating wire 155a to protect the heating wire and make it airtight.

Here, since the heating cable 155 has an elastic sheath 155b, it is positioned between the horizontal panel closing cap 170 and the solar panel 110 and between the vertical panel closing cap 150 and the solar panel 110. Airtightness can be achieved only by the elastic force of the elastic shell (155b) without installing an airtight seal.

The heating cable 155 may be a constant power heating cable with no change in output value as the heating wire 155a is designed in a parallel circuit structure, and the elastic outer shell 155b may be formed of an elastic material such as silicone, urethane, rubber, etc. .

As shown in FIG. 1, the solar power generation device 101 that prevents freezing by using a heating cable according to an embodiment of the present invention may include an anti-icing control unit 210.

This anti-icing control unit 210 can prevent freezing of the solar panel 110 through the heating cable 155, which is heated by supplying electricity to the heating cable 155 when it snows.

The anti-icing control unit 210 may be installed on the connection panel 200 that collects electricity generated from a plurality of strings (ST), and the anti-icing control unit 210 includes a snow detection unit 213 and a power generation measurement unit 211. may include.

The anti-icing control unit 210 may operate the heating cable 155 based on the information provided by the snow detection unit 213.

The snow detection unit 213 can detect snowfall, and the snow detection unit 213 can measure the amount of snow and provide the detected information to the anti-icing control unit 210.

The snow detection unit 213 includes a temperature sensor and can determine whether snowfall is detected and provide the temperature measured by the temperature sensor to the anti-icing control unit.

The snow detection unit 213 can be implemented by a known snow detection module, and the snow detection unit 213 can detect snow in the form of measuring the amount of power generated by the string (ST) of the solar panel 110. It may be possible.

For example, when the power generation amount in winter is significantly reduced compared to the previous power generation amount, the snow detection unit 213 determines that snow has occurred on the solar panel 110 and provides the information that snow has occurred to the anti-icing control unit 210. can do.

The anti-icing control unit 213 can operate the heating cable 155 based on only one information of whether snowfall is detected by the snow detection unit 213 or a temperature below a preset temperature.

However, in order to accurately operate the heating cable 155, the anti-icing control unit 210 detects snowfall in the snow detection unit 213 and lowers the preset temperature at which freezing may occur (for example, -1°C or lower). It is desirable to configure the heating cable 155 to operate only when the furnace temperature is measured.

The anti-icing control unit 210 may include a power generation measurement unit 211.

The power generation measurement unit 211 can measure the power generation output for each string (ST) in the panel array installed on the roof and provide the power output to the anti-icing control unit 210.

The power generation measurement unit 211 can measure the voltage or current of the power generation measured in each string (ST) and provide it to the anti-icing control unit 210, and the anti-icing control unit 210 measures the power generation amount measurement unit 211. The heater cable 155 can be operated by providing electricity from the string (ST) with the highest power generation among the plurality of strings (ST) to the heater cable (155).

If the heater cable 155 is supplied from the string (ST) without the power generation measurement unit 211, the electricity generated in the string (ST) located relatively at the top of the roof among the plurality of strings (ST) is connected to the heater cable (155). ) can be provided.

Here, the string (ST), which is usually located at the top of the roof, has the highest power generation because snow flows down and the top of the solar panel 110 is partially exposed even if snow is covered by the wind, so the power generation measurement unit 211 If the amount of power generation cannot be measured through , only electricity from the string (ST) located at the top may be provided to the heater cable 155.

In addition, when the anti-icing control unit 210 determines that snow has formed on the solar panel 110, it quickly supplies power to the heater cable 155 through a zero relay that can immediately switch power supply in a known power unapplied state. This can prevent freezing.

Meanwhile, the anti-icing control unit 210 may not be configured separately, but may be integrated with the known string optima 230 described above.

When it snows in winter, the solar power generation device 101, which prevents freezing by means of a heating cable according to an embodiment of the present invention configured as described above, receives information about the snowfall detected by the snowfall detection unit 213 and the snowfall detection unit 213. The temperature measured by the temperature sensor is transmitted to the anti-icing control unit 210.

The anti-icing control unit 210 supplies electricity to the heating cable 155 when snow is detected by the snow detection unit 211 and the temperature measured by the temperature sensor is below the preset temperature. The supplied electricity compares the power generation of each string (ST) transmitted from the power generation measuring unit 211, and transmits the electricity of the string (ST) with the highest power generation to the heating cable (155).

When electricity is supplied to the heating cable 155, the heating cable 155 is heated, melting ice formed on the solar panel 110, or preventing ice from forming from the beginning when it snows, thus preventing the solar panel 110 from forming. The power generation amount of (110) can be increased.

The panel stand 130 may include a panel seating part 131, a stand drain part 132, a guide wing part 133, and a stand hook part 136.

The panel seating portion 131 may be formed to face each other on both upper sides of the panel support 130 to seat the solar panel 110, and the panel seating portion 131 is located on the edge of the solar panel 110. The frame 111 of the solar panel 110 may be seated on the panel mounting portion 131.

The panel support 130 may include a vertical vibration transmission unit 138.

This vertical vibration transmission unit 138 can prevent vibration occurring in the longitudinal direction (front and rear directions) of the roof by transmitting it to the elastic support 140.

The vertical vibration transmission unit 138 may be installed in the support insertion part 137 into which the upper end of the elastic support 140 is inserted, and the vertical vibration transmission unit 138 uses fastening members such as bolts, nuts, rivets, or screws. The panel stand 130 may be configured to pass through and fasten the stand hook portion 136 on one side in the horizontal direction.

Here, the vertical vibration transmission portion 138 may be formed in the form of a plate connecting a pair of pedestal hook portions 136 facing each other to the support insertion portion 137 and formed integrally with the panel pedestal 130. Since the panel stand 130 is manufactured continuously by drawing or injection, it is preferable to install a pair of stand hook portions 136 through the fastening member.

The vertical vibration transmission unit 138 supports the panel support 130 in a direction perpendicular to the longitudinal direction of the elastic support 140 inserted into the support insertion part 137, thereby forming a vertical vibration transmission unit during vibration in the longitudinal direction. As (138) is supported on the elastic supporter 140, vibration can be prevented by the elastic force of the elastic supporter 140.

At this time, the upper part of the elastic support 140 inserted into the support insertion part 137 has a transmission groove 145 into which the vertical vibration transmission part 138 is inserted in a direction perpendicular to the longitudinal direction of the elastic support 140. can be formed.

A plurality of vertical vibration transmission units 138 may be installed on the panel stand 130 side by side at preset intervals along the longitudinal direction of the panel stand 130.

As shown in Figures 5 to 7, the building-integrated solar power generation roof structure 100 equipped with a solar power generation device that prevents freezing by a heating cable according to an embodiment of the present invention includes an elastic support 140. It can be included.

This elastic support 140 is located between the panel support 130 and the fixing clip 120 to prevent vibration transmitted from the panel support 130 or the base support 180 by the elastic force of the elastic support 140. A plurality of elastic supports 140 may be installed spaced apart along the longitudinal direction of the panel stand 130, or may be formed to have a length corresponding to the panel stand 130 to support the panel stand 130.

The elastic support 140 may be made of a material having elasticity, such as natural or synthetic rubber, urethane, silicone, or synthetic resin.

The elastic support 140 may include an insertion protrusion 141 and a buffer support 143.

The insertion protrusion 141 may be inserted and coupled to the support insertion portion 137 formed on the panel support by protruding from the upper part of the central portion of the elastic support 140.

A transmission unit groove 145 that is inserted and spanned may be formed in each portion where the vertical vibration transmission unit 138 is located.

Here, the vertical vibration transmission unit 138 is inserted into the transmission groove 145 in a direction perpendicular to the longitudinal direction of the elastic support 140 (transverse direction). Therefore, when vibration in the longitudinal direction (front-back direction) occurs, the vertical vibration transmission unit 138 is caught in the transmission groove 145 and is prevented from vibrating by the elastic force of the elastic support 140, thereby improving earthquake resistance.

Meanwhile, the buffer support 143 may be formed to protrude from both sides of the elastic support 140. When vibration is applied to the elastic support 140, the buffer support 143 repeats compression and expansion due to elastic deformation. When doing so, the clip buffering portion 123 formed on the fixing clip 120 can be pressed and released to increase elasticity, thereby improving vibration resistance.

For example, when a vibration greater than the elastic force that can prevent the elastic support 140 from vibrating occurs, both sides of the elastic support 140 are supported by the clip buffer 123 and are not suppressed by the clip buffer 123. Therefore, by elastically deforming the clip buffer 123 together with the elastic support 140, it is possible to improve vibration resistance by increasing vibration cushioning, and the elastic support 140 is an elastic body and the clip buffer 123 is a metal. Because of this, the vibration isolation can be further improved by the different elastic forces between the different types.

The buffer support portion 143 is in close contact with the clip buffer portion 123, so that even if the elastic support body 140 is elastically deformed by a small amount of pressure, the clip buffer portion 123 can be elastically deformed by pressing the inner circumference of the clip buffer portion 123. It may be formed in a shape having an outwardly convex curved surface corresponding to the curved surface of .

Here, since the shock absorber 143 has an outwardly convex shape, when the elastic support 140 is compressed by vibration, the shock absorber 143, which has relatively weak strength, is more easily elastically deformed, and the clip shock absorber ( 123) can be elastically deformed in the clip buffer 123 by pressing it.
