Common issues in Hawaii
Cell hotspots
Localised overheating in individual cells caused by micro-cracks, shading, or manufacturing defects. Best detected via thermal imaging.
Typical loss: 5–20%
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%
