Solar panel hotspots: what they are and why they matter in Northern Ireland
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.
Northern Ireland has a cool maritime climate with 3 peak sun hoursper day. The UK's cooler temperatures benefit panel efficiency but shorter daylight hours affect annual output.
