The frame 220, which can mount the solar module, may be connected to the clamp 210 as a single unit or a combined unit. In addition, the form in which the clamp 210 surrounds the verandah railing 100 may be a form in which the clamp 210 is fastened by the integral clamp 210, or a form in which the clamp 210 'is separated into two and both ends are coupled to each other.

The fastening portion of the clamp 210 is coupled using bolts, nuts, or the like. On the clamping surface of the clamp 210, the connection portions 230 having different polarities are disposed on the same surface on both sides, and both connection portions 230 are electrically connected when fastened.

Here, the connection portions 230 may be arranged correspondingly to a plurality of positions on both sides of the fastening surfaces of the clamps so as to detect the change of the fastening state due to a short circuit and determine the strength of the connection portions 230. The connection portions 230 are mounted on the flexible substrates 231 and 232 , And attached to the clamping surface 211, 212 of the clamp 210.

The alarm unit 240 (not shown) may be installed in a plurality of positions in the form of a light emitting device in a position where detection of the fastening state change and strength can be easily recognized from the outside. The clamping state change intensity can be displayed by changing the luminescent color depending on the degree of the clamping state change or by using a blinking pattern or the like.

The connection state monitoring unit 250 may detect a short circuit of the connection unit 230 when the sensing unit 251 detects that the connection unit 230 is short-circuited and the connection state monitoring unit 250 may detect the connection state of the connection unit 230 based on the short- A control unit 253 for controlling the display of the alarm unit 240 according to the determination result, a transmission unit 254 for transmitting the information to the user and the manager terminal, And a power supply unit 255 receiving power and supplying the power to the alarm unit 240 and the connection unit 230.

A method of real-time monitoring of the state where the solar module shelf 200 of the present invention constructed as described above is fastened to the verandah railing 100 will be described in detail.

The clamp 210 clamping the solar module shelf 200 and the verandah railing 100 may be damaged due to durability and warping due to a certain period of time or an external impact such as wind or vibration A phenomenon may occur.

The phenomenon in which the clamp 210 is opened usually proceeds from the outside to the inside, and it can proceed slowly or progress rapidly depending on the installation period or the strength of the impact.

If the phenomenon that the clamp 210 is opened slowly progresses, the connection portion 230 located outside of the clamping surface may be dropped and the current may be short-circuited.

When the phenomenon of the clamp 210 opening rapidly progresses, a plurality of connection portions 230 may be sequentially or simultaneously short-circuited.

When the clamping state monitoring unit 250 senses a short-circuit of the current flowing in the connection unit 230 due to the expansion of the clamp 210, the connection state monitoring unit 250 senses the position or the number of the short- The strength is judged. Controls the light emission pattern of the display unit according to the determined intensity of change, and simultaneously transmits the information to the occupant and the photovoltaic module facility manager by wire or wirelessly.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be understood that various modifications and changes may be made without departing from the scope of the appended claims.
