Document Type and Number:
Japanese Patent JP6479645
Kind Code:
A diagnosis system including: a power collection unit configured to couple a plurality of photovoltaic cell arrays, each including photovoltaic cells, in parallel; a control unit; and a monitoring unit, the monitoring unit being configured to: estimate a solar radiation amount and an operating temperature of the photovoltaic cell arrays based on the current value measured by a first ammeter in the control unit and the voltage value measured by the first voltmeter in the control unit by using an expression expressing a relationship between the solar radiation amount, the operating temperature, and a number of photovoltaic cells, and an output current; correct the estimated values so as to match the current values measured by second ammeters in the power collection unit by using the expression; and calculate a theoretical current value of each of the photovoltaic cell arrays based on the corrected values by using the expression.
