Arcing

Junction box failure

9 minute read

Published:

Junction boxes are the connection gates between modules, and their failures can result in substantial performance degradation, safety hazards like internal arcing, and even potential fires.

Bypass diode

Bypass diode failure

8 minute read

Published:

Bypass diodes have a pivotal role in PV modules and their failures might lead to significant performance losses and even safety issues like fire or electric arcs.

Cable

Cable defect

3 minute read

Published:

Cables are omnipresent over the PV array and enable the electrical connection between the PV array elements. Cable failures are among the most severe due to their frequency and impact on their performance [1].

Cell crack

Cell cracks

11 minute read

Published:

Silicon within PV modules is brittle, and cell cracks are expected in the natural aging of PV modules. However, some severe cracks might lead to high mismatches, potentially activate bypass diodes, and significantly decrease power module performances.

Connector

Connector defect

5 minute read

Published:

Connectors are widely used throughout PV systems and electrically connect PV modules to each other, to combiner boxes, fuse boxes or inverters [1]. Nevertheless, connector failures can lead to dramatic consequences such as open-circuits, insulation faults, electrical risks and, even fire.

Corrosion

Severe metallization corrosion

8 minute read

Published:

Degradations induced from water ingress have the potential to trigger critical levels of corrosion which have been demonstrated to decrease the module maximum power by 80% in the worst-case during damp-heat tests [1].

Fire

Junction box failure

Published:

Junction boxes are the connection gates between modules, and their failures can result in substantial performance degradation, safety hazards like internal arcing, and even potential fires.

Glass breakage

Glass breakage

8 minute read

Published:

Glass breakage is a common PV module failure that impacts plant safety and performance, potentially leading to insulation faults that can stop the entire plant operation.

LID

Light Induced Degradation (LID)

5 minute read

Published:

Light Induced Degradation (LID), or Light soaking effect, refers to changes in module power performance due to light exposure and could potentially entail losses up to 30%. This article provides an overview on the impact, the loss mechanisms and how to detect LID.
