6 FAQs about [Photovoltaic panel ir test]
Why is IR imaging used in PV power plants?
1. Introduction Thermography, also called infrared (IR) imaging, has been a frequently used tool for years to detect faulty or underperforming modules and strings in PV power plants. IR is so attractive because the images are taken during operation in a non-contact and non-destructive way without interfering with the electrical system.
How to detect PV module anomalies in IR images?
Detection of PV module anomalies Similar to the PV module detection, many existing works identify anomalous PV modules in IR images with classic image processing techniques. The most popular one is binary thresholding of image intensities, which segments hot regions of PV modules corresponding to thermal anomalies [ 91, 92, 97, 102, 104, 109 ].
Why is infrared imaging important for PV module evaluation?
