Solar panel hotspots: what they are and why they matter in Maryland
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.
How Maryland's climate affects this issue
Moderate climate conditions present average hotspot risk. Age and panel quality are the primary factors.
