Title:
SOLAR CELL MODULE DETERIORATION DIAGNOSIS SYSTEM
Document Type and Number:
Japanese Patent JP2018082602
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fault diagnosis method accurately identifying a fault location of a solar cell module and having high identification efficiency without information on the solar cell module having no faulty part, and the like.SOLUTION: A solar cell module 1 for deterioration diagnosis and a power conditioner 2 are disconnected, constant voltage power supply 3 applies a voltage to a solar cell module 1 side, the solar cell module 1 is caused to generate electroluminescence emission, the electroluminescence emission is photographed by a near infrared camera 4 mounted on an unmanned aircraft 7 that flies by a transceiver 8, the photographed electroluminescence emission is stored in an electronic computer 5, and deterioration situation of the solar cell module 1 is identified by an image analysis program 6 in the electronic computer 5. In a case of a small-scale photovoltaic power generation facility in which photographing from a vehicle for high lift work or the like, an operator on the vehicle for high lift work performs photographing on the vehicle for high lift work without using the unmanned aircraft 7.SELECTED DRAWING: Figure 1
