ApplicationDistributed Photovoltaic Power Station
Project background
During the full lifecycle operation of photovoltaic power stations, dust, oil stains, environmental pollutants, and long-term surface contamination on
PV modules can significantly reduce the light transmittance of solar glass, directly affecting power generation efficiency and power station revenue.
Traditional manual cleaning can only provide short-term cleaning effects and often fails to fundamentally solve continuous dust accumulation,
pollutant adhesion, and efficiency decline.
As an important distributed photovoltaic project in the region, the Anhui Bengbu New Energy Power Station has an installed capacity of 3.7MW.
The station faced common industry challenges such as dust accumulation on module surfaces, declining power generation efficiency,
and high operation and maintenance costs. To break through the efficiency bottleneck and maximize long-term return on solar assets,
the customer cooperated with Yingcai New Materials to introduce an integrated “deep cleaning + nano coating” technology service solution.
Project introduction
Based on the actual operating conditions of the power station, Yingcai New Materials customized a dual technology solution combining deep
photovoltaic module cleaning and nano self-cleaning coating application.
The solution was designed to first remove accumulated dust, oil stains, bird droppings, and stubborn contaminants from the module surface
through professional deep cleaning. After restoring the basic surface cleanliness and light transmission performance, Yingcai applied its
self-developed photovoltaic nano self-cleaning coating to the module surface.
The nano coating forms a dense protective layer on the solar glass surface through advanced molecular structure technology. It provides
self-cleaning, anti-soiling, weather resistance, surface protection, and transmittance enhancement performance, helping reduce dust
adhesion from the source while improving long-term module cleanliness and power generation stability.
Efficient Project Delivery
For this 3.7MW photovoltaic power station, Yingcai organized a professional team and completed the full-station cleaning and coating
upgrade in about 10 days.
The work was carried out efficiently without affecting the normal operation of the power station. Yingcai implemented standardized on-site
management, process control, and technical testing to ensure that every stage of the project met photovoltaic power station operation
and maintenance requirements.
The project demonstrated Yingcai’s ability to deliver integrated photovoltaic cleaning, nano coating application, and field testing services
for distributed solar power stations.
Two-Stage Performance Testing
Stage 1: Cleaning Performance Test
In the first stage, Yingcai used its eco-friendly photovoltaic cleaning solution to thoroughly clean dust, oil stains, bird droppings, and other
stubborn surface contaminants from the PV modules. After cleaning, the basic transmittance and surface cleanliness of the modules were restored.
Test results showed that the cleaning process alone increased power generation by approximately 8%.
Stage 2: Cleaning + Nano Coating Combined Test
In the second stage, after deep cleaning, Yingcai applied its self-developed photovoltaic nano self-cleaning coating to the module surface.
The coating created a protective layer with self-cleaning, anti-soiling, transmittance enhancement, weather resistance,
and long-term surface protection properties.
After the combined cleaning and nano coating upgrade, the overall power generation efficiency of the power station increased by 33.1%.
Full-Process Compliance and Service Assurance
The entire project was implemented under a professional photovoltaic power station efficiency improvement service framework.
Yingcai provided standardized operation procedures, professional on-site施工 management, and performance data monitoring
to protect the customer’s project results and long-term operating interests.
All cleaning, coating, and testing processes were carried out in accordance with photovoltaic power station operation and maintenance requirements,
ensuring both project effectiveness and customer asset safety.
