This single crystal 175 watt module features 16.4% encapsulated cell efficiency and 14.2% module efficiency. Using breakthrough technology perfected by Sharp's nearly 45 years of research and development, these modules use a textured cell surface to reduce reflection of sunlight, and BSF (Black Surface Field) structure to improve conversion efficiency. An anti-relective coating provides a uniform blue color and increases the absorption of light in all weather conditions.
