Photovoltaic Nano-Enhanced Clean Coating
I. Product Overview
This product primarily employs the synergistic wetting principle of organic coupling-inorganic nanoparticles, utilizing glass microstructure bonding cross-linking technology. After undergoing bonding and cross-linking chemical treatment, the glass surface acquires a transparent nano-clean coating. This coating bonds with the glass surface microstructure, providing reliable adhesion that reduces the adhesion of dust and other contaminants to the photovoltaic module glass surface. Simultaneously, the glass surface becomes easier to clean, enhancing the maintenance efficiency of solar panels and improving power generation efficiency.
II. Product Features and Performance
• Theoretical outdoor operational lifespan of 3 years
• Resistant to high and low temperatures while being environmentally friendly
• Proven to reduce cleaning frequency on photovoltaic module glass surfaces
• Helps solar panels maintain cleanliness longer between cleanings
• Tests indicate the coating has no impact on photovoltaic conversion efficiency
• Excellent dust resistance and self-cleaning protection

III. Process Implementation Steps
1. Thoroughly clean the surface of the photovoltaic module to be treated. Ensure the glass panel surface is free of dust, stains, and other contaminants, maintaining a dry and clean state.
2. Apply the dedicated cleaning agent once to the surface of the photovoltaic module that has been washed with water and dried. Then, brush this product's nano-coating onto the glass surface of the photovoltaic module, spreading it evenly. At this point, a nano-enhancement easy-clean coating will adhere to the glass surface.
3. After application, avoid touching the glass surface for at least 4-8 hours under natural room temperature conditions. Keep it dry and free from water contact to allow the coating to undergo cross-linking and bonding with the glass.
4. Storage Instructions: Store in a sealed container in a cool, dry place. Avoid high temperatures and prolonged exposure to air.
5. Coating application is not recommended during rainy weather.
