Title:
DETERMINATION DEVICE AND DETERMINATION METHOD
Document Type and Number:
Japanese Patent JP2023009783
Kind Code:
A
Abstract:
To easily detect distortion occurring on a panel surface of a power generation unit in a photovoltaic power generation system at low cost.SOLUTION: A determination device is used in a photovoltaic power generation system including a power generation unit including a solar cell panel, and includes an acquisition unit that acquires measurement information indicating a measurement result of the output current of the power generation unit, and a determination unit for calculating a statistical value which is a value in at least any one of a first time zone, a second time zone and a third time zone in a time order per day based on the measurement information acquired by the acquisition unit, the value being based on the output current of a target power generation unit which is the power generation unit to be determined, and the determination unit performing determination processing for determining distortion of the surface of the solar cell panel in the target power generation unit based on the calculated statistical value.SELECTED DRAWING: Figure 7
