Tesla Solar — cell hotspots
Hotspots can affect any panel manufacturer, including Tesla Solar. They're caused by cell-level defects, micro-cracks, or persistent shading — not by brand quality alone. However, panel construction quality and cell technology do influence hotspot susceptibility.
Cell hotspots is a known issue for Tesla Solar panels. This doesn't mean it will affect your system — but it's worth monitoring.
