Thermometer measures photovoltaic panels and shows red

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.

How is temperature measured on a solar panel?

The temperature at three points is measured using the FBG sensor. This three-point measurement is selected based on the pre-measurement experiments conducted on the same panel with more diagonal locations. Researchers can vary the number of sensor locations based on the solar panel type and size.

How to identify a solar photovoltaic panel?

identify the panel using a thermal imaging system and processes the thermal images using the image processing technique. An spots. Similarly, the new and aged solar photovoltaic panels were compared in the image processing technique since any fault in the panel has been recorded as hot spots.

What should a thermographer look for in a solar panel?

Viewing angle and position. The viewing angle and position are important for good thermographic measurement. The camera must be well aligned with the solar panel. Horizontal alignment 60-90°, and the vertical alignment should be close to the angle of solar radiation. Note the thermographer’s shadow aligned with the sun in Fig. 12.

How does temperature affect solar photovoltaic (PV) performance?

Solar photovoltaic (PV) performance is affected by increased panel temperature. Maintaining an optimal PV panel temperature is essential for sustaining performance and maximizing the productive life of solar PV panels. Current temperature sensors possess a long response time and low resolution and accuracy.

How do I perform a solar thermography inspection?

For good thermography inspections select a clear, dry day. Measure solar radiation with an appropriate light meter to make sure that the solar radiation is at or above 650 W/m2. In direct sunlight solar panels work at full capacity and damaged solar cells will show clearly on the infrared image.
