Re-yingcai® Photocatalytic Self-Cleaning Nano Coating for PV Glass is a photovoltaic protective treatment independently developed by Dongguan Yingcai New Material. It combines nano titanium-dioxide photocatalysis with a silane-based hydrophobic system. Under light, the coating automatically decomposes oil, sand, dust and organic deposits on the panel surface, while a strong lotus-leaf hydrophobic effect allows rainwater to wash the loosened contamination away. It helps maintain high PV glass light transmission, reduces solar-plant cleaning and O&M costs, and is suitable for both new PV modules and refurbishment of aging solar installations.
Product Features
-
High Transmittance & Light GainThe highly transparent coating does not block sunlight, supporting efficient light capture by PV modules and steady improvement in power output.
-
Photocatalytic Contaminant DecompositionLight-activated performance rapidly decomposes stubborn contaminants such as oil and bird droppings, while rainwater washing cleans the panel without frequent manual work.
-
Long-Lasting Weather ResistanceResists UV exposure, acids, alkalis and windblown sand, with strong adhesion and outdoor service life of up to eight years in complex solar-plant environments.
-
Lower Cost & Higher EfficiencyExtends cleaning intervals, reduces O&M labor costs and supports stable power-generation revenue for lower overall solar-plant operating expense.

High Transmittance for Greater Power Output
The coating is thin, transparent and has minimal impact on glass light transmission, allowing a very high proportion of solar energy to reach the PV cells. It can improve light utilization and support a stable 13%–20% increase in power-generation efficiency, helping protect long-term solar-plant output across a wide range of PV applications.
Strong Photocatalysis for Automatic Contaminant Removal
Natural light activates the photocatalytic coating to efficiently decompose stubborn contaminants such as oil, dust, bird droppings and tree resin. Combined with its self-cleaning surface properties, rainwater automatically washes away loosened contamination, reducing the need for frequent manual cleaning and keeping PV glass clean.
Corrosion and UV Resistance for Outdoor Durability
-
The product resists ultraviolet exposure, acid rain and salt spray while withstanding windblown-sand abrasion and day-night temperature swings. Strong adhesion prevents the coating from peeling, supports stable performance in exposed outdoor environments and provides an actual service life of up to eight years.
Easy Application for Significant Cost Savings
-
The coating supports multiple simple application methods, forms rapidly and cures naturally at room temperature. By extending module cleaning intervals, it substantially reduces manual washing and equipment-maintenance expenses, simplifies solar-plant operations and lowers overall O&M investment.
