Wherein the data collecting section includes a measuring section for measuring the temperature of the solar cell module and a data transmitting section for receiving and transmitting information about the temperature of the solar cell module from the measuring section, A deterioration diagnosis unit for extracting information about a temperature of the solar cell module from the temperature data transmitted from the data server, And a failure determination unit for determining whether or not a failure has occurred, and for transmitting information on the failure to the data server.
The measuring unit measures the output voltage and current of the solar cell module in real time and transmits the information to the data transmitting unit. The data transmitting unit transmits information about the output voltage and the current received from the measuring unit to the data server The data server may store information on the output voltage and the current and transmit the information to the data management unit.
If the information on the critical temperature value received from the deterioration diagnosis unit continues, the data server interrupts the power generation of the solar generator at the same time as a fire alarm is sounded. If the information less than the critical temperature value lasts for 2 to 3 minutes The fire alarm can be canceled and the power generation interruption of the solar generator can be canceled.
The data server transmits to the data management unit information on the power generation amount of the solar power generator, the output voltage of the solar cell module, the current, and the temperature, and when an emergency occurs, This can alert the administrator.

Solar generators generally include various configurations such as a solar cell module, a power conditioner, and an inverter. The solar cell module is a power generation means for converting solar energy into electric energy. It can be installed in a place where a large-scale solar generator such as a power plant or an industrial complex is required in addition to a small-scale solar generator of 3 kW or less for household use. Such solar cell modules are modularized by connecting solar cells of semiconductor materials in series and in parallel, and various types of solar cells such as crystalline silicon solar cells, polycrystalline silicon solar cells, and thin film silicon solar cells can be used have.

If the information about the temperature above the critical temperature value is continuously extracted and determined to be faulty, and the information below the critical temperature value is received, the fire alarm is canceled and the power generation interruption of the solar generator is also canceled.
At this time, the temperature may be measured sporadically due to the surrounding situation. Therefore, it is determined that the temperature is lower than the critical temperature value for about 2 to 3 minutes after the fault is detected. It is desirable to release the power generation interruption and the power generation interruption of the photovoltaic generator. This is because it corresponds to the secondary reference value for the failure judgment. The reason why the primary reference value and the secondary reference value are provided for determining the failure is that it is preferable that the criterion for the risk situation judgment be strictly controlled.
