6 FAQs about [Principle of infrared imaging of photovoltaic panels]

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 infrared images can be obtained from a photovoltaic power plant?

Infrared images can be get by equipped drones of photovoltaic (PV) power plants , which can be used to analyze abnormal situation of the PV panel. However, infrared images are easily affected by external factors during the imaging process.

What are the advantages of infrared (IR) imaging for PV modules?

g techniques, which identify faults and problems developing with PV modules.The use o infrared (IR) imaging for the evaluation of PV modules has many advantages. First of all, a great number of failures developed on PV modules can be detected

What is infrared and electroluminescence imaging for PV field applications?

of infrared (IR) and electroluminescence (EL) imaging for PV field applications. This document shall help to identify, record and assess the most common failures of PV modules and components in the field. The editors of the document are Ulrike Jahn and Magnus Herz, TÜV Rheinland, Germany (DEU).

How do PV panels differ from infrared thermal imaging?

In contrast to infrared thermal imaging detection in PV panels, the detection of electronic components differs due to their complex and intricate structures. Often, external excitation is required to induce heating for these electronic components.

Can thermal imaging be used to identify a solar PV module?

One of the significant challenges is the fault identification of the solar PV module, since a vast power plant condition monitoring of individual panels is cumbersome. This paper attempts to identify the panel using a thermal imaging system and processes the thermal images using the image processing technique.
