Solarclean Series

To address the rapid efficiency loss caused by outdoor contamination of photovoltaic panels, Iridium Technology provides a highly effective solution with its self-cleaning coatings.

This series includes two coating products to adapt to specific environmental contamination characteristics:
Solar Panel Superhydrophilic Coating YNT-GF-002; Solar Panel Hydrophobic Coating YNT-GF-001
For severely contaminated photovoltaic panels, we offer the professional Solar Panel Deep cleaning solution YNT-GF-QX, which can quickly restore surface light transmittance and power generation efficiency. Depending on the contamination level, processing time typically ranges from 5 to 30 minutes.

Core Functions & Advantages

Slide

Self-Cleaning
● Utilizes biomimetic principles on specially wetted surfaces to dynamically combine hydrophilic/hydrophobic and oleophilic/oleophobic behaviors as needed, effectively preventing dust and contaminants from adhering.

● Multiple Patented Technologies
1. Self-Cleaning Coating for Photovoltaic Panels Resistant to Carbon and Calcium Sulfate Deposition CN202411541663.4
2. Self-Cleaning Coating for Photovoltaic Panels Resistant to Bird Droppings CN202411541508.2
3. Self-Cleaning Coating for Photovoltaic Modules Resistant to Salt Crystallization CN202411541405.6
4. Self-Cleaning Coating for Photovoltaic Panels Resistant to Fluoride Corrosion CN202411540854.9

applied synchronously to the coating, providing comprehensive protection against various contamination sources.

Enhanced Light Transmission & Heat Dissipation
● Selectively filters spectral bands that do not contribute to power generation but increase panel temperature, reducing operational temperature and improving energy efficiency.
● Micro-nano core-shell technology: forms a non-film structure via surface chemical grafting, enhancing visible light transmittance.

● On top of clean glass surfaces, additionally improves 1.5–2%

light transmittance. Nano-scale inorganic materials create uniform surface roughness, reducing refractive index discontinuities.

Superior Weather Resistance

● The coating demonstrates excellent weather resistance, withstanding outdoor sun, rain, high/low temperature cycles, and UV exposure; maintains stable performance and appearance over time, with a service life of up to five years.

Applications

Slide

Where to Use

Applicable across all stages of the photovoltaic industry chain, from module glass rolling to PV module assembly and on-site power plant operations. The coating can be easily applied at manufacturing sites or directly in the field.

How to Apply

After standard cleaning, simply spray or brush the coating. With self-leveling properties, it spreads evenly on its own and dries quickly, making the application effortless and efficient.
