Hereinafter, a monitoring method for a solar panel according to the present disclosure will be described in detail with reference to FIGS. 1 to 8.

4 is a flowchart illustrating a monitoring method for a solar panel according to a first embodiment of the present specification.

First, the sensing unit 810 detects (or measures) voltages or currents respectively received at a plurality of input terminals included in the plurality of connection panels 200. Here, the input terminal forms one channel and receives (or receives) a voltage or current output from a plurality of solar cell modules or one solar cell module connected in series. At this time, the plurality of solar cell modules or one solar cell module connected in series, each of the unique identification information is set, form a group.

For example, as illustrated in FIG. 5, the detector 810 may include a first-first input terminal 211 and a first-second input terminal 212 included in the first connection panel 210, and The voltage or current input to the 2-1 input terminal 221 and the 2-2 input terminal 222 included in the second connection panel 220 are respectively sensed. Here, the first-first input terminal 211 included in the first connection panel 210 is connected to the first group 511 and the first-second input terminal included in the first connection panel 210. 212 is connected to the second group 512, and the 2-1 input terminal 221 included in the second connection panel 220 is connected to the third group 513, and the second connection panel The second-2 input terminal 222 included in the 220 is connected to the fourth group 514. In this case, each of the first group 511, the second group 512, the third group 513, and the fourth group 514 includes a plurality of solar cell modules 100 connected in series, respectively (S410). ).

Thereafter, the controller 830 compares the voltages or currents of the plurality of input terminals sensed by the sensing unit 810 with the voltages or currents of the input terminals adjacent to the corresponding input terminals, respectively.

For example, the controller 830 may be configured to transfer a voltage (for example, 250V) of the 1-2 input terminal 212 detected by the sensing unit 810 to the adjacent 1-1 input terminal 211. ) Is compared with the voltage (for example, 290V) and / or the voltage (for example, 300V) of the 2-1 input terminal 221 (S420).

Then, the control unit 830, as a result of the comparison, the voltage or current of any input terminal included in the plurality of input terminals is within a preset error range for the voltage or current of the input terminal adjacent to the arbitrary input terminal. When not present, it is determined that there is an error (or an error) in at least one solar cell module among the plurality of solar cell modules included in the specific group connected to the corresponding arbitrary input terminal, and generates an alarm signal. Here, the alarm signal is not only a video signal and an audio signal, but also a signal (or a control signal for vibrating the monitoring system 800 for solar panels or any terminal) for notifying an event occurrence by vibration. Error message (or error information) including information on the group in which the generated solar cell module is included.

That is, the control unit 830, as a result of the comparison, the voltage or current of the arbitrary input terminal is "voltage / current of the adjacent input terminal-a predetermined error" and "voltage / current of the adjacent input terminal + preset When not within the range of " error ".

For example, as a result of the comparison, the controller 830 determines that the voltage of the first-first input terminal 211 (for example, 250 V) of the first-second input terminal 212 is adjacent to each other. For example, an error range preset for 290V (for example, 275.5V to 304.5V for an error of 5%) and / or a voltage of the adjacent 2-1 input terminal 221 (for example, 300V). ) Is not included within the preset error range (eg, 285V to 315V for 5% error), and thus is included in the second group 512 connected to the 1-2 input terminal 212. It is determined that there is an abnormality in at least one solar cell module of the plurality of solar cell modules, and generates an alarm signal.

In addition, when the voltage or current of any input terminal included in the plurality of input terminals is not within a preset error range for the voltage or current of an input terminal adjacent to the arbitrary input terminal. (Or at the time of generating the alarm signal), based on the geographic arrangement of the entire grouped plurality of solar cell module 100 stored in advance in the storage unit 820 contained in a specific group connected to the corresponding arbitrary input terminal The location of the solar cell module is checked, and additional information including information (or location information) about the grouped solar cell module in which the identified abnormality occurs is generated (S430).

Thereafter, the controller 830 outputs the generated alarm signal through the display unit 840 and / or the voice output unit 850.

In this case, the controller 830 outputs the generated additional information through the display unit 840 and / or the voice output unit 850 or through the communication unit 860 to collect the information 700. And / or to the terminal number / email of the pre-registered administrator.

For example, the control unit 830 transmits the generated alarm signal to the terminal of the pre-registered manager through the communication unit 860 (S440).

As described above, instead of a method in which the controller 830 compares output voltages / currents of a plurality of grouped solar cell modules adjacent to each other, voltages or currents of the plurality of input terminals sensed by the sensing unit 810. May be compared with a preset reference value, and the alarm signal may be generated when a voltage or current of a specific input terminal among the plurality of input terminals does not exist within a tolerance range of the reference value.
