sunMAX Panels are based on proven, industry-standard technology whose lifetime extends to 25+ years effective use. The Multi- / Poly-Crystalline material is widely chosen for residential installations due to its low cost-to-efficiency ratio.
Expect that virtually every panel will encounter minimal power degradation over the lifetime of the panel. If 0.4% drop in power occurs annually, expect about 1W of loss per year (ex. 255W * 0.004 = 1.02W).
Under real world conditions, you may see slightly more due to dust, man-made pollution, etc.
- SM-MI-250-*: 95.5%
- SM-SP-260-DC-*: 15.6% (up to 5% under 260W DC power)
* - NA (North America) or EU (Europe/World) models
