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.
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 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.
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.
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.
