YINGCAI Photovoltaic Nano Self-Cleaning Coating Empowers SPIC Solar Power Stations, Improving PV Efficiency by Over 30%

A clean technology transformation driven by nanomaterials is reshaping the operation and maintenance model of large-scale solar power stations. YINGCAI New Materials has successfully applied its photovoltaic nano self-cleaning coating to more than 200 solar power stations under State Power Investment Corporation, helping improve module cleanliness, enhance light transmission, reduce maintenance frequency, and increase overall power generation efficiency by over 30%.

As PV modules are exposed to outdoor environments for long periods, dust, bird droppings, industrial pollutants, sand, salt mist, and organic contaminants can easily accumulate on the glass surface. These pollutants reduce light transmission, weaken power output, and increase the cost and risk of manual cleaning. YINGCAI’s nano self-cleaning coating provides a long-term solution for improving PV operation efficiency in complex outdoor environments.

Technical Highlights

The coating forms a transparent functional layer on the surface of PV glass, combining self-cleaning performance with light-enhancing properties. Through nano-scale surface design, the coating helps reduce pollutant adhesion and allows rainwater to remove dust and dirt more easily from the module surface.

The self-cleaning mechanism is based on a bionic surface structure. With excellent hydrophobic performance, rainwater can roll off the surface and carry away dust particles. At the same time, the functional coating helps reduce the adhesion of organic pollutants, allowing the PV modules to maintain a cleaner surface for a longer period.

In addition, the coating helps improve optical performance. By reducing surface reflection and enhancing visible light transmission, more sunlight can reach the solar cells, increasing the power generation potential of the PV system from the source.

Application Value

State Power Investment Corporation operates solar power stations across deserts, coastal areas, industrial zones, and other challenging environments. After applying YINGCAI photovoltaic nano self-cleaning coating, the coated modules showed improved surface cleanliness, more stable power generation performance, and reduced operation and maintenance pressure.

In dusty northern regions, the coating helps reduce dust accumulation and improve effective sunlight absorption. In coastal power stations, the coating provides better resistance to salt mist and humid environments. In industrial areas, it helps reduce the impact of pollutants and airborne particles on PV module performance.

For large-scale solar power stations, this solution can reduce manual cleaning frequency, lower water consumption, decrease maintenance costs, and reduce the risk of module damage caused by repeated cleaning. It is especially suitable for utility-scale solar farms, desert PV projects, coastal PV stations, industrial rooftop PV systems, and existing PV station retrofit projects.

Industry Significance

The application of YINGCAI photovoltaic nano self-cleaning coating demonstrates the practical value of nano coating technology in large-scale PV operation and maintenance. By combining self-cleaning, light-enhancing, anti-dust, and long-term protection functions, the solution helps customers improve power generation efficiency while reducing long-term operating costs.

This project also shows that advanced material technology can become an important tool for improving the economic performance of renewable energy assets. With wider application in new solar power stations and existing PV projects, YINGCAI’s nano coating solution will continue to support cleaner, more efficient, and more sustainable solar energy development.
