Thermal imager photovoltaic panels

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.

What does a thermal image of a solar panel show?

A thermal image of a solar panel, such as the one shown here, reveals defective cells within the panel. Overheating cells can hinder the entire photovoltaic system's performance. The used camera includes a microbolometer detector that generates thermal images with a resolution of 640x480 pixels and a thermal sensitivity of 35mK (0.035 deg C).

Can you use thermal imaging to inspect solar panels?

Thermal imaging can be used to inspect solar panels under load, so no shutdown is required. When used properly, thermal imaging cameras will show accurate temperature differences between cells or within a single cell that allow you to identify faults at an early stage.

What is the best thermal camera to use with solar panels?

We selected 4 of the best thermal cameras to use with solar panels and evaluated them on every aspect from image quality to battery life and software features. Let’s have a look at each product in particular. If you are serious about inspecting your solar panels, then the best camera to use is the Flir E8-XT.

Should you use drone thermal imaging for solar panel inspections?

Using drone thermal imaging for solar panel inspections is an efficient and cost-effective way to identify issues, optimize performance, and maintain the integrity of solar installations. Here's how you can benefit from automated visual inspections on your solar farm:

Does a thermal image indicate a fault in a PV panel?

Considering that the change of the visual image does not necessarily mean the presence of a fault in a PV panel, the thermal image of the PV panel is more favoured in the practice of PV panel condition monitoring (Kandeal et al., 2021a).
