When part of a solar panel is shaded, dirty, cracked, or damaged, that area cannot produce electricity like the rest of the panel.
Instead of generating power, it resists the electrical current coming from other cells.
This resistance creates heat, and over time that heat concentrates in one spot — this is known as a hotspot.
If the hotspot remains undetected, the panel materials can slowly break down, increasing the risk of failure and ignition.
Solar panels are connected using DC connectors.
If these connectors are:
they can create high electrical resistance.
High resistance means more heat, and in DC systems this can lead to arcing (electrical sparks) — a recognised cause of rooftop solar fires.
DC isolators are designed to safely disconnect the solar system.
However, fires can occur if DC isolators are:
According to Australian fire incident investigations, DC isolators and connectors are frequently involved in rooftop solar fire events.
No two solar installations are the same.
Each project differs in:
That is why proper design, analysis, and documentation are essential.
As a solar system owner — small or large — you should always request and keep:
from the designer and installer of your system.
Yes. All electrical components can be assessed using thermography.
In practice, a single inspection may include several different tests to build a reliable final report.
However, thermography is a proven method for clearly identifying abnormal behaviour in cables and connectors.
Faulty or stressed cables and connectors often generate localized heat, which can be detected early through thermal imaging — before visible damage or failure occurs.
What can cause cables or connections to overheat?
Several common issues can cause a cable or connection to run hotter than normal:
Yes. Prolonged high temperatures can significantly increase fire risk.
When cables or connectors overheat:
Over time, this combination of heat, degraded insulation, and electrical stress can create conditions that allow a fire to start, especially in rooftop solar installations where combustible materials may be nearby.
Thermography allows us to identify problems before an incident occurs.
Many electrical faults do not fail suddenly.
They develop gradually, producing abnormal heat long before smoke, fire, or visible damage appears.
Thermal imaging makes this hidden heat visible at an early stage.
This means issues such as hotspots, stressed cables, or overheating connections can be detected before they turn into serious incidents.
By identifying these warning signs early, corrective action can be taken in time — helping to prevent fires, system damage, and unplanned shutdowns.
