Solar panel hotspots: what they are and why they matter in Queensland
Hotspots are localised areas of overheating on a solar panel, typically caused by cell damage, micro-cracks, or persistent shading. They are the leading cause of accelerated panel degradation and are best detected via thermal imaging. Here's what you need to know.
Queensland has a subtropical climate with 5.8 peak sun hours per day.
