Common issues in Mesa
Cell hotspots
Localised overheating in individual cells caused by micro-cracks, shading, or manufacturing defects. Best detected via thermal imaging.
Typical loss: 5–20%
Panel soiling
Dust, pollen, bird droppings, or debris accumulation reducing light absorption. More severe in arid or agricultural areas.
Typical loss: 2–15%
Inverter efficiency loss
Degradation or malfunction in the inverter reducing DC-to-AC conversion efficiency. Often indicated by error codes or unexpected shutdowns.
Typical loss: 5–25%
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: 3–15%
