Solar Panel Assessment Using Thermal Imaging Camera

Posted · Add Comment

Thermal imaging camera captures the radiation intensity in the infrared region of the spectrum and converts it to visible image. Infrared energy from an object is focused by optics onto the infrared detector, which translates the data collected from detector into an image which can be viewed on the screen. Thermal imaging cameras are used for monitoring and diagnosing solar panels. They identify the problems at an early stage, which can be rectified and hence will save us from more costly repair before the problem became more serious.

Thermal Imaging cameras are an established tool in research and development sector for evaluation of solar cells and panels. Usually high performance cameras with cooled detectors are used in laboratory work. However, these are not just restricted the field of research. Uncooled thermal image cameras are used for quality check of solar panels before installation and also regular maintenance check ups once the panel has been installed.

In order not to draw false conclusions you need to hold the thermal imaging camera under a correct angle when inspecting solar panels.
