Core Advantages
- Low Light Performance: Retains an average relative efficiency of 97.5% under lower irradiance environments (200W/m²).
- Temperature Coefficient: Features a low thermal coefficient of -0.35%/°C, resulting in superior energy output in hotter climates.
- Degradation Resistance: Gallium-doped technology curbs Light-Induced Degradation (LID). Power output drops by ≤2% in year one, followed by a linear annual loss of ≤0.55% up to year 25.
- Mechanical Durability: Handles static heavy snow loads up to 5400 Pa on the front and wind forces up to 2400 Pa on the rear.
