<P>PROBLEM TO BE SOLVED: To provide a solar energy generation diagnostic system which conducts more reliable failure diagnosis. <P>SOLUTION: Power generation information, solar insolation information, and temperature information are obtained (S100), and these pieces of information are recorded (S110). A predicted power generation amount is calculated by using an actual insolation amount obtained based on the insolation information and a panel temperature obtained based on the temperature information (S120 to S140). Further, the actual power generation amount is calculated based on the power generation information (S150). When the error between the actual power generation amount and the predicted power generation amount becomes a certain value or more, the diagnostic system displays the diagnosis of the system failure of the solar energy generation system (S160:YES, S170). Furthermore, the diagnostic system adjusts a design coefficient, which is obtained by quantifying power generation loss factors, by using a loss coefficient obtained by SV method, the rating capacity of PCS 20, and the deterioration correction coefficient which is preset according to a type of the solar cell (S130). <P>COPYRIGHT: (C)2012,JPO&INPIT |
