Infrared Imaging as a PV Characterization Tool - Self Study
About this course
The use of infrared images is a well-known technique for building inspections and electrical trouble shooting. It is also very useful in diagnosing the health of PV modules working in the field.
Other than monitoring the overall array energy generation, IR imaging is one of the few techniques available to get detailed information on the health of PV modules after they are installed. This information can be critical in identifying both performance and safety issues. Many potential problems can be found and rectified before they significantly impact performance or generate an unsafe condition. A broad range of defects, including those related to manufacturing and workmanship details can be identified, if you know what to look for.
IR imaging is a powerful tool to access the health of modules while that operate in the array. It should be a routine part of all PV quality acceptance programs, as well as annual operations and maintenance programs.

Infrared Imaging as a PV Characterization Tool
This lecture reviews the IR imaging technique as it applies to PV modules and discusses equipment, weather conditions, and array operating conditions. Approximately half of the lecture is devoted to real-world examples of IR images of defective modules. Participants will receive guidance on how to interpret IR images in order to determine what requires immediate attention versus what may be normal and expected for a functioning solar array.
