Solar panel hotspots: what they are and why they matter in South Australia
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.
South Australia has a arid climate with 5.9 peak sun hours per day. High soiling risk makes this issue particularly relevant. Extreme conditions accelerate degradation.
