Why do photovoltaic equipment need to be cleaned with dry ice
Time:2025-06-03 Category:【Industry dynamics】Read:15
The performance of photovoltaic equipment, especially solar panels, is highly dependent on the cleanliness of the surface. Dust, dirt, bird droppings and other impurities not only reduce the exposure of sunlight, but may also cause hotspot effects, damage photovoltaic panels and reduce their lifespan. Although traditional cleaning methods can remove some dirt, it is necessary to use dry ice to clean photovoltaic equipment in the following aspects:
1. Cleaning without water and chemicals
In many regions, water resources are extremely valuable, and using water to clean photovoltaic panels consumes a large amount of water. In addition, the use of chemical cleaning agents may cause damage to the protective layer of photovoltaic panels, and the residue of chemical agents may cause pollution to the environment. Dry ice cleaning does not require water or chemicals, which can reduce the consumption of water resources and potential impact on the environment during cleaning.
2. Avoid physical damage
Dry ice cleaning is a non abrasive cleaning method that can effectively remove dirt without damaging the sensitive surfaces of photovoltaic panels. In contrast, traditional cleaning (especially scrubbing) may scratch photovoltaic panels, reduce their light absorption rate, and affect long-term performance.
3. Improve cleaning efficiency
Using dry ice cleaning can significantly improve cleaning efficiency. Dry ice particles will immediately sublime upon impact with dirt, rapidly separating dirt and surface through their expansion effect, thus achieving efficient cleaning without water flow or scrubbing.
4. Reduce downtime
The power generation of a photovoltaic power station is directly related to its operating time. Dry ice cleaning can be carried out without electricity, reducing downtime caused by cleaning, correspondingly reducing operating costs, and improving power generation efficiency.
5. Improve staff safety
Photovoltaic panels are usually installed on rooftops or other high-altitude locations, and workers face the risk of slipping and electric shock when using wet cleaning methods. Dry ice cleaning reduces these risks and can improve the safety of workers through remote control operation.
6. Environmentally friendly
Reducing the impact on the environment is particularly important for renewable energy equipment. Dry ice cleaning does not generate harmful waste, does not increase total carbon dioxide emissions, and meets the goals of sustainable development.
conclusion
The use of dry ice cleaning for photovoltaic equipment not only improves cleaning efficiency, but also reduces physical damage to the equipment. In addition, it demonstrates superiority over traditional cleaning methods in saving water resources, improving work safety, reducing downtime, and complying with environmental protection standards. As the photovoltaic industry moves towards higher efficiency and environmental standards, dry ice cleaning will become the preferred method for maintaining photovoltaic equipment.
