- This solar cell module is intended to eliminate the need for the inspection operator to confirm the failure in the vicinity of the module by means of communication, but it can only detect abnormalities in the electrical parameter values and is externally affected by the weather. It was difficult to accurately extract only the failed solar cell module by removing the factors.
- Patent Document 3 proposes a solar power generation system that displays that there has been a change when there is a predetermined change or more between past power generation data and current power generation data. This system also compares current power generation data with past power generation data, and has the same problem as that of Patent Document 2.

- the current value of the majority of the solar cell modules or strings is lower than a certain percentage, and even if a fault of the solar cell modules or strings exists, it is a very small part of the whole, and the majority operates normally. Furthermore, we focused on the fact that the influence of external factors such as the weather on the current value of the solar cell module or string does not differ greatly as long as they are present in a certain time.

- the measured current value of each solar cell module or string is a constant ratio from the current value of one solar cell module or string calculated from the total current value of the entire system. If the solar cell module or the string in the lowered state is only extracted as a failure candidate when it is lowered as described above, the failure detection can be achieved by a very simple method.
- the current values to be compared are based on solar modules or strings in almost the same environment at the same time that are almost equally affected by external factors such as weather. Therefore, the failure candidate can be extracted with high accuracy by removing the influence of the external factor without performing any processing.

- the method of the present invention can be used from a small system installed on the roof of a home to a large system with a power generation of 1 megawatt or more, but a very large number of solar cell modules or strings are installed, This is extremely effective in a mega solar system with a power generation amount of 1 megawatt or more, which requires a great deal of labor for the inspection work.
- the number of modules per string is not particularly limited as long as it is plural, and the number of strings in the system is not particularly limited as long as it is also plural. .
- the number of modules per string is preferably 3 to 100, and the number of strings in the system is preferably 100 to 10,000.
- the individual solar cell modules used in the system and the number of modules per string need to be set to be the same in order to make an accurate comparison of current values.
- the cause of the decrease in the power generation amount (current value) of the solar cell module or the string is temporary that can be ignored and permanent that requires repair or replacement.
- Temporary causes include sunshine hours and the presence of clouds, rainy weather, building shadows, regular maintenance, etc.
- permanent causes include solar cell module failure, disconnection, and backflow prevention diode damage , Failure of measuring devices and communication means, bird droppings, etc.
- the power generation amount is reduced due to a permanent cause that truly requires repair or replacement, excluding those in which the power generation amount is reduced due to a temporary cause that can be ignored. Only the solar cell module or string is detected as being defective.
- the present invention is a solar cell module per unit calculated from the total current value of the entire system in which the measured current values of individual solar cell modules or strings are measured at substantially the same environment at the same time.
- the module or string in the reduced state is extracted as a failure candidate.
- the current value is measured either for each solar cell module or for each solar cell string, depending on the unit in which the failure is to be detected.
- measurement is preferably performed for each module, and when the scale is large or it is desired to reduce the number of measuring devices from the viewpoint of cost, measurement is preferably performed for each string.
- the comparison of the current value depends on the unit to be measured, and is performed between the measured current value of one module and the average current value of one module, or the measured current value of one string and the string per string. Between the average current values.
- the average current value per module or the average current value per string is calculated by dividing the measured total current value of the entire photovoltaic power generation system by the number of modules or the number of strings.
- the measured current value of one solar cell module or the current value of one solar cell string is calculated as described above.
- the solar cell module or the solar cell string in the reduced state is extracted as a failure candidate.

Further, when the total current value of the entire system shows zero or an extremely low value, it is difficult to extract a failure candidate, so it is preferable to temporarily stop measurement or comparison.
- the failure candidate solar cell module or string may be extracted based on a comparison result only at a certain time, but in order to improve accuracy, the current value decreases by a certain percentage or more even after a certain period of time. Preferably, only existing modules or strings are extracted as failure candidates.
- the duration of the reduced state of the current value of the module or string required for extraction in this case is preferably 10 minutes or more, 30 minutes or more, 1 hour or more, 3 hours or more, 4 hours or more, 8 hours or more, 1 day or more, It can be 3 days or more and 7 days or more.
