6 FAQs about [Photovoltaic panel hot spot sample image]
Can photovoltaic panels detect hot-spot faults?
The research on hot-spot fault detection of photovoltaic panels can be roughly divided into two directions: using the electrical characteristics of photovoltaic panels and using the infrared image characteristics of photovoltaic panels [ 7, 8 ].
How do PV hotspots affect the physical and thermal image?
The physical and thermal image of a PV module is affected by hotspots; the thermal image is captured using a FLIR i5 thermal imaging camera, which has a thermal sensitivity of ± 1 \ (^\circ \) C. There are currently undergoing investigations on how PV hotspots occur in PV modules.
What are hot spots in PV panels?
By inductive analysis, hot spots of PV panels can be divided into three classes in shape: round, linear, and square ones, which can represent various hot spots of PV panels common in the field operation of PV power stations. Fig. 2 shows the three typical types of hot spots in PV panels.
How to detect hot spot defects in infrared image PV panels?
Aiming at the problem of difficult operation and maintenance of PV power plants in complex backgrounds and combined with image processing technology, a method for detecting hot spot defects in infrared image PV panels that combines segmentation and detection, Deeplab-YOLO, is proposed.
Can a new model be used for real-time photovoltaic panel hot-spot fault detection?
A comprehensive comparison of the accuracy, detection speed, and model parameters of each model showed that the indicators of the new model are superior to other detection models; thus, the new model is more suitable to be deployed on the UAV platform for real-time photovoltaic panel hot-spot fault detection.
Do you need a detection system for hot spots of PV panels?
