State Power Investment Corporation - Xinjiang Hami Hongxing Phase II 20MW Photovoltaic Power Station Self-Cleaning Coating Demonstration Project

Hisenmec photovoltaic self-cleaning nano protective coating forms a long-lasting superhydrophilic coating by constructing a roughness with concave-convex structures below 50nm. It features wear resistance, light transmission enhancement, anti-static properties, and superhydrophilicity. The product's performance durability can reach 3-5 years effectively in the northwest region, and no less than 5 years in other regions; compared to conventional cleaning, the initial comprehensive power generation increase can reach 2.2-2.6%, with a long-term power generation increase greater than 5%. Hisenmec always prioritizes customer service. Through quality control of products, upgrading of technical processes, and improvement of the service system, it has created an efficient service experience tailored to the operational and maintenance needs of photovoltaic power stations, while also redefining the service standards of the photovoltaic operation and maintenance industry.

Project Background
To improve the operating environment of photovoltaic power generation and ensure the efficiency of photoelectric conversion, on October 22, a demonstration project of self-cleaning, dust-proof, and anti-static nano-coating was carried out at the 20MW Phase I photovoltaic power station of State Power Investment Corporation at Hongxing Second Farm, Hami, Xinjiang.

The State Power Investment Corporation Phase I photovoltaic power station at Hongxing Second Farm, Hami, Xinjiang, is located within the Hongxing Second Farm area of Hami City, Xinjiang. The site is 21 km from Hami City, 12 km north of National Highway G312, 13 km from Provincial Road S235, and 300 meters west of a rural road, providing convenient transportation. The plant site is divided into the photovoltaic area and the substation management area. The project capacity is 20MWp, using 300Wp polycrystalline silicon solar panels, totaling 66,980 units.

On-site Survey and Analysis
Before starting work, the person in charge must check whether safety measures are complete and comply with the safety measures and start conditions listed in the work permit. Before commencement, it is necessary to verify that safety technical measures have not been altered. Only after confirming no issues can work begin. In the early construction phase, a survey and analysis of the Xinjiang Hami Hongxing Second Farm Phase I photovoltaic power station project site were conducted to assess pollution levels, understand and analyze pollution sources, and perform preliminary data testing.

Photovoltaic Nano Self-Cleaning Construction
Based on the current pollution status on site, professional technical service engineers conducted on-site surveys and analyses, selectively choosing cleaning agents and material ratios to apply self-cleaning coatings on the photovoltaic panels. This ensures the panels are restored to maximum cleanliness, thereby improving power generation efficiency.

Hisense Meike photovoltaic self-cleaning nano protective coating forms a long-lasting superhydrophilic coating by creating a roughness structure with concave-convex features below 50nm. It features wear resistance, light transmittance enhancement, anti-static properties, and superhydrophilicity. The product's effective performance duration in the Northwest region can reach 3-5 years, and no less than 5 years in other regions; compared to conventional cleaning, the initial comprehensive power generation increase can reach 2.2-2.6%, with long-term power generation increase exceeding 5%.
Hisense Meike always prioritizes customer service by controlling product quality, upgrading technical processes, and improving the service system, creating an efficient service experience tailored to the operational and maintenance needs of photovoltaic power stations, while also redefining service standards in the photovoltaic operation and maintenance industry.
