Anti-corrosion and Insulation Nanocoating Solutions for Photovoltaic Equipment

Aug 07,2025

1. Industry Pain Points
Photovoltaic equipment is exposed to harsh outdoor environments for long periods, facing serious corrosion and insulation performance degradation issues. Corrosive media such as sea breeze, acid rain, salt spray, and industrial exhaust gases can erode the metal components of photovoltaic equipment, leading to reduced structural strength and shortened service life. Meanwhile, the accumulation of dust, moisture, and other pollutants decreases the insulation performance of electrical equipment, increasing the risk of short circuits, leakage, and other faults, which affects the normal operation of photovoltaic power plants. Traditional protective measures, such as paint coatings, tend to peel and crack after long-term use, gradually weakening their protective effect. Once equipment fails, repairs are difficult and costly, potentially causing prolonged power outages and significant economic losses to the power plant.
2. Hisense Meike Solutions
Hisense Meike's anti-corrosion and insulation nano-coatings provide comprehensive protection for photovoltaic equipment. The coating has excellent anti-corrosion properties, forming a strong protective film on the equipment surface that effectively blocks oxygen, moisture, and corrosive media from contacting the substrate, slowing corrosion. At the same time, the coating offers superior insulation performance, significantly improving the insulation resistance of electrical equipment and reducing leakage risks. Additionally, the coating has good wear resistance and weather resistance, enabling it to adapt to various harsh environmental conditions and maintain stable protective performance over the long term.
3. Implementation Steps
Equipment Survey: Conduct detailed surveys of various equipment within the photovoltaic power plant, including photovoltaic brackets, inverters, distribution boxes, etc., to understand the material, operating environment, corrosion, and insulation status of the equipment, and develop targeted construction plans.
Surface Treatment: For metal equipment, first remove surface rust, oxide scale, and other impurities by methods such as sandblasting and grinding to achieve a certain surface roughness to enhance coating adhesion. Then, use specialized cleaners to remove oil and dust, ensuring the surface is clean and dry. For electrical equipment, care must be taken during cleaning to avoid water or cleaning agents entering the interior; dry cloth wiping or compressed air blowing can be used for cleaning.
Coating Application: Choose appropriate application methods based on the type and part of the equipment. For large flat equipment such as photovoltaic brackets, spraying can be used; for complex-shaped or small equipment such as electrical components, brushing or dipping methods can be applied. During application, strictly control coating thickness and environmental conditions according to product instructions to ensure uniform coverage without missed spots or runs.
Quality Inspection: After coating application, conduct comprehensive testing of coating performance. Use coating thickness gauges to ensure thickness meets design requirements; perform adhesion and hardness tests to verify coating adhesion and hardness; use insulation resistance testers to check the insulation performance of electrical equipment coatings. Only equipment that passes quality inspection can be put back into use. Regularly inspect and maintain equipment coatings, promptly repairing damaged areas to ensure protective effectiveness.
4. Expected Effects
Extend Equipment Service Life: Effectively prevent equipment corrosion, extend service life, and reduce replacement costs. It is expected to extend the service life of photovoltaic equipment by more than 5 years, enhancing the asset value preservation and appreciation of the power plant.
Improve Equipment Operational Safety: Enhance the insulation performance of electrical equipment, reduce the risk of short circuits, leakage, and other faults, ensuring the safe and stable operation of photovoltaic power plants. It is expected to reduce the failure rate caused by insulation issues and decrease power outage incidents.
Reduce Maintenance Costs: Decrease the frequency and cost of repairs caused by corrosion and insulation problems. Additionally, due to the coating's good wear and weather resistance, daily maintenance workload is reduced, saving manpower and material resources. This results in significant maintenance cost savings over the entire lifecycle of the photovoltaic power plant.
Increase Power Plant Reliability: Ensure the normal operation of photovoltaic equipment, improve the power generation reliability of photovoltaic power plants, and provide users with continuous and stable power supply.
