Title:
A solar energy power generation system and a diagnosing method of a solar cell module
Document Type and Number:
Japanese Patent JP6096099
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a photovoltaic power generation system and the like for appropriately diagnosing whether abnormality occurs to a solar battery module.SOLUTION: A photovoltaic power generation system S includes solar battery modules 11 to 16, sensor modules 21 to 26 and a power conditioner 30. The power conditioner 30 can implement maximum power point tracking including hill climbing and scanning. If it is determined that a current value of the solar battery module 11 is equal to or higher than a predetermined threshold during implementation of the hill climbing, the sensor module 21 diagnoses the solar battery module 11 during implementation of the scanning after determination.
