That is, according to the integrated management system of the photovoltaic device, when the temperature of the solar cell module constituting the specific photovoltaic device rises and does not produce proper power, the control server detects this and operates the cooling device to spray water. As a result, water sprayed from the cooling device lowers the temperature of the solar cell module so that proper power production is possible.

In addition, it is possible to integrate and manage a large number of photovoltaic devices that are difficult to access due to geographically separated installations, and when abnormal operation occurs in a specific photovoltaic device, the management personnel detects abnormalities of the photovoltaic devices at the remote site.

It can be confirmed immediately so that quick response is possible.

In the integrated management system of the photovoltaic device, not only an operation signal generator for generating an operation signal related to the operation of the photovoltaic device is provided for each photovoltaic device, but also a plurality of photovoltaic devices. Since the module abnormal operation indicator which is connected to the solar cell module of the solar cell module and displays the abnormal operation status of the solar cell module has to be installed, the overall component is increased and the wiring error or unnecessary power consumption during the actual use is increased.
