Is your rooftop solar power station experiencing a decline in power generation? The cleanliness of the solar panels directly impacts power generation efficiency, and professional cleaning and maintenance ensures continuous and efficient operation. Below, we'll explain in detail the optimal cleaning cycle, operating procedures, and mainstream cleaning methods for rooftop solar power stations, helping to stabilize and improve their efficiency.

First, understand: photovoltaic panels"Surface properties" are largely the same as those of glass.

The surface of the core power-generating area of ​​a photovoltaic module has similar properties to glass, a material commonly found in our daily lives.—Whether it's the glass tiles on the roof, the glass in the windows of your home, the windshield of your car, or the lenses of your everyday glasses,glass containersMobile phone camera andelectronicScreens, like any glass product, require regular cleaning to maintain their light transmittance, and photovoltaic panels are no exception.

Once you understand this, it's easy to see that there's no fixed standard for the number of times photovoltaic panels need to be cleaned. The key is to judge based on the actual situation. Whenever something affects light transmission, the panels should be cleaned promptly to ensure the power station is always in optimal power generation condition.

II. Cleaning cycle: dynamically adjusted according to the scenario, power generation+The actual state is the core signal

To determine whether cleaning is necessary, power generation data should be used as the primary source.+Based on visual inspection, adjustments can be made flexibly in conjunction with the environmental context:

1. Core judgment criteria: After excluding factors such as component shading, equipment failure, and changes in sunlight, if the daily power generation decreases by more than [a certain percentage]...5%-10%Or visually inspect the surface of the photovoltaic panels for dust,Bird droppings, weeds, leavesThe proportion of obstructions reached2%For those of the above caliber, cleaning should commence immediately;

2. Routine basic cleaning: It is carried out in conjunction with daily appearance inspection, which is quick and easy to operate, and avoids the rapid impact of slight shading on power generation efficiency.

3. Regular deep cleaning: Weekly for normal scenarios1Secondly, during the rainy season and after sandstorms, special attention should be paid to thoroughly remove stubborn stains;

4. Special scene adjustments: For areas with frequent sandstorms and smog...3-5Daily inspection and cleaning1Next, in rainy areas, wait for the components to dry after rain, and use a soft brush to clean away any remaining mud, sand, and water stains; in autumn and winter, promptly remove fallen leaves, frost, and snow to prevent obstruction and physical damage caused by freezing ice and snow.

III. Preparations before cleaning: Safety first, pay attention to details for protection

1. Personnel safety regulations: Workers must wear safety helmets, insulated gloves, and insulated shoes. When working on the roof, safety belts must be fastened, and the entire process must be supervised by a dedicated person. Unlicensed personnel are strictly prohibited from operating.

2. Work time selection: Avoid severe weather such as thunderstorms, strong winds, high temperatures, rain, snow, and freezing, and choose a time when the environment is suitable;

3. Safety precautions: Disconnect the DC and AC power supplies to the photovoltaic system before cleaning, and hang a "Do Not Close Switch, People Working" warning sign to eliminate the risk of electric shock.

IV. Cleaning Tools and Materials: Choosing the Right Ones"Equipment" to prevent component damage

1. Preferred tool: Soft-bristled brush+Use clean water to gently clean without damaging the components (just like cleaning glasses or a mobile phone screen, avoid scratching).

2. For stubborn stains: A small amount of diluted neutral detergent can be used. After cleaning, rinse thoroughly with water to avoid detergent residue.

3. Absolutely prohibited: Hard tools (steel wool, scrapers)piece(etc.) to prevent scratching the glass surface; strong acidic or alkaline chemicals to avoid corroding the component frame or glass.

V. Key Precautions During the Cleaning Process

1. Avoid sudden temperature changes: When the component temperature is high, do not rinse it directly with cold water to prevent the glass from cracking (similar to the principle that high-temperature glass is easily damaged when exposed to cold water).

2. Do not step on the components: It is strictly forbidden to step on the component frame or glass surface to avoid deformation or damage to the components;

3. Requirements for third-party outsourcing: It must be confirmed that the operators hold a "Low-voltage Electrician Certificate" and relevant operation and maintenance qualifications in the photovoltaic industry, and strictly follow cleaning and maintenance standards.

VI. Mainstream Cleaning Methods: Comparing manual and machine cleaning, the most cost-effective solution is selected.

Photovoltaic panel cleaning is mainly divided into two categories: manual cleaning and machine cleaning. The choice can be made based on actual needs, with manual cleaning offering more comprehensive advantages.

(a) Manual cleaning: Highly efficient and effective cleaning+Economical and practical, the preferred solution

1. Operating procedure: First, rinse the surface dust of the photovoltaic panel with water, then use a special electric photovoltaic cleaning tool for deep cleaning, and finally wipe it dry with a mop to ensure that there are no residual water stains or dirt.

2. Key advantages: High cleanliness, capable of precisely handling corners and stubborn stains, suitable for various rooftop power station scenarios; fast operation speed, no complex debugging required; controllable cost, outstanding cost performance, no need for large equipment investment;

3. Recommended choice: Jingkai Manual Cleaning Team. Our professional staff are certified and follow standardized procedures, balancing cleaning effectiveness, efficiency, and safety, making us a more worry-free option.

(ii) Machine cleaning: A variety of equipment are available, and the costs and risks need to be weighed.

Machine cleaning mainly includes the following4There are several common types, and their limitations should be carefully considered when choosing one:

1. Photovoltaic cleaning robots: They have good cleaning effect, but their operation speed is relatively slow, and machine debugging and fault repair will further affect efficiency; the equipment investment cost is high, ranging from tens of thousands to hundreds of thousands of yuan, which is not cost-effective for small power plants.

2. Fixed track cleaning device: requires pre-customized installation of guide rails, has limited adaptability, and has high initial investment and subsequent maintenance costs;

3. Automatic water pressure cleaning equipment: relies on water pressure control, has limited cleaning accuracy, is prone to leaving water stains, and requires manual re-inspection;

4. Drone cleaning: Suitable for large-area unobstructed power stations, but with a high risk factor, including the risk of equipment falling, requiring additional insurance; greatly affected by wind and obstacles, making it difficult to guarantee cleaning coverage and effectiveness.

VII. Professional TeamCleaningSystematic serviceshaveEffective guarantee

Choosing a professional photovoltaic cleaning team (such as Jingkai Manual Cleaning Team) can prevent equipment damage caused by improper operation from the source. The professional team will strictly follow scientific cleaning standards, combine them with the power station's exclusive operation and maintenance manual, and accurately match cleaning tools and appropriate time periods, making the entire operation efficient and controllable. After cleaning, the condition of each photovoltaic panel will be checked (no scratches, no component misalignment), and the power generation will be observed. This systematic service ensures the long-term stable operation of the power station.
