6 FAQs about [GEM photovoltaic hot spot]

What is a hot spot in a PV module?

In a photovoltaic (PV) module, a hot spot describes an over proportional heating of a single solar cell or a cell part compared to the surrounding cells. It is a typical degradation mode in PV modules. Hot spots can origin, if one solar cell, or just a part of it, produces less carrier compared to the other cells connected in series.

What are hot spots in PV panels?

By inductive analysis, hot spots of PV panels can be divided into three classes in shape: round, linear, and square ones, which can represent various hot spots of PV panels common in the field operation of PV power stations. Fig. 2 shows the three typical types of hot spots in PV panels.

How do PV hotspots affect the physical and thermal image?

The physical and thermal image of a PV module is affected by hotspots; the thermal image is captured using a FLIR i5 thermal imaging camera, which has a thermal sensitivity of ± 1 \ (^\circ \) C. There are currently undergoing investigations on how PV hotspots occur in PV modules.

Why do PV module hotspots go unnoticed?

More often than not these hotspots go unnoticed due to small changes in the module's current-voltage characteristics: which makes thermal imaging a very crucial part of the PV module health monitoring and fault diagnostic.

Does localised heating cause hotspot formation?

Abstract: Localised heating within a solar cell gives rise to hotspot formation, which further leads to module damage and system degradation. It has been observed that even for healthy PV modules, uneven dust depositions can lead to mis-match in the output characteristics, resulting into hotspots with as high as 200% higher temperatures.

What causes array hot spots in PV panels?

Furthermore, the array hot spots of PV panels are caused by a single internal defect of PV panels or multiple-panel failures in series and parallel, and its structure is featured with scattered or clustered square shape.
