Infra-red thermal camera for solar panel inspections

The photos show the real example of testing results using the infra-red thermal camera.  From top to bottom:

1) One section of the solar panel is poorly connected inside the junction box. The whole section generates less power and overheats.

2) Junction box overheating. The overheating of the junction box due to poor cable connection inside. It causes the over heating of the solar cells above the box and causing poor power performance.

3) The dirt from birds excrement. The panel itself is 100%. However the dirt covers a particular cell that does not work properly and overheats extremely. As a result the performance of the whole solar panel will decrease. The panels must be clean from this kind of dirt!

4) A defective cell. There is no visible reason of the malfunction. Only the thermal-camera is able to discover this kind of manufacturing defect.
