1. What is Anti-Reflective (AR) Coating?
Anti-Reflective (AR) coating is a porous nano-silica ($SiO_2$) layer applied onto low-iron glass. Through destructive light interference, it minimizes surface reflection, allowing 2.5% to 5.0% more sunlight to pass through compared to untreated glass.
The Impact: Standard low-iron glass provides ~91.5% light transmittance. Adding AR coating raises total light transmission to 94.0% - 97.5%, directly translating into higher energy production and accelerated crop growth.
2. Dual Sector Benefits
Commercial Greenhouses (Double-Sided AR):
Yield Rule: In horticulture, 1% more light equals ~1% higher crop yield during low-light winter months.
Hemispherical Transmittance: Effectively captures diffuse and low-angle morning/evening sunlight.
Hydrophilic Surface: Reduces condensation droplet buildup, preventing light scattering and crop damage from dripping water.
Solar PV & Thermal Collectors (Single/Double-Sided AR):
Power Output Boost: Increases solar module power generation by 2% to 3% through reduced Fresnel reflection losses.
Thermal Collector Gain: Maximizes fluid temperature in flat-plate solar thermal systems.
Outdoor Durability: Engineered for anti-soiling, UV stability, and long-term mechanical weatherability.
