Common issues with Canadian Solar

Natural panel degradation

All solar panels lose efficiency over time at roughly 0.5–0.8% per year. Accelerated in extreme heat or poorly manufactured panels.

Typical loss: 315%

Panel soiling

Dust, pollen, bird droppings, or debris accumulation reducing light absorption. More severe in arid or agricultural areas.

Typical loss: 215%

Cell hotspots

Localised overheating in individual cells caused by micro-cracks, shading, or manufacturing defects. Best detected via thermal imaging.

Typical loss: 520%
