The cleaning process should be done during hours when the production of photovoltaic panels is low. This can happen early in the morning or late in the evening. In this way, cleaning is achieved without any loss in production.

2. Preparation of Necessary Equipment
In the equipment to be used for photovoltaic panel cleaning, it is important to use materials that will not damage the panel surface and use a solvent that will not leave marks on the solar panels after cleaning. For example, since there are no solids in pure water, it will not leave any traces on the solar panels after cleaning.

3. Checking the Surface of the Panels
Before starting the cleaning process, the surface of the panels should be checked for any damage. Broken or cracked panels should not be cleaned, and an authorized service should be consulted for repair.

4. Cleaning Process
A soft brush or cloth should be used to avoid damaging the surface of the panels. Abrasive substances and hard brushes should never be used. Panels should be washed with pure water that does not contain chemicals. Water is applied evenly to the surface of the panel to soften the dirt. If there is concern about the mineral content of the water, water with low mineral content can be used. In cases of heavy contamination, soap or special cleaning solutions recommended by the manufacturer can be used. These solutions allow dirt to be removed easily. If soap or solution was used, the panels should be rinsed with plenty of water. No chemical groups must remain on the panels.

5. Regular Checks and Maintenance
Regularly checking the panels and determining the frequency of cleaning is important for long-term efficiency. Panels located in especially dusty and dirty areas may need to be cleaned more frequently.

Photovoltaic panel cleaning is one of the main ways to maintain and increase energy efficiency. Regular and correct cleaning prolongs the life of the panels and ensures maximum energy production. Therefore, care should be taken during the cleaning process and the manufacturer’s instructions should be followed.

What Should Be Considered When Cleaning PV Panels?

What Should Be Considered When Cleaning PV Panels?

Pollution in photovoltaic panels creates a layer that prevents sunlight from entering the cell. As the mass of dust accumulation increases, the power output and efficiency of the module decrease. In order to avoid this loss of efficiency, photovoltaic panels must be cleaned correctly and regularly.

Pure deionized water must be used to clean photovoltaic panels. Deionized pure water is free from dissolved substances in the water. Unlike solutions (Acidic, Basic, Alcohol), deionized pure water does not leave stains on the panels. An additional rinse may be required when using a solution. Thus, after cleaning, there is no obstacle to sunlight reaching and absorbing the panel. Detergents and chemical containing products should not be used to clean photovoltaic panels from dust and dirt without being sure of their content. Test reports of the solutions to be used should be examined and the mixture should be prepared and used at the specified concentrations.

If the solution is used in high amounts, marks can be seen on the glass surface of the solar panels and corrosive effects on the sub-construction, as shown in the image.

Figure 1. Effects on Solar Panels and Construction after Solution Use

Cleaning the panels always brings with it the risk of being caught in high voltage. To avoid being electrocuted, the panels should be cleaned with non-conductive deionized pure water. In this way, occupational safety can be protected. When cleaning the photovoltaic panel, care should be taken to ensure that the temperature of the water and the temperature of the panel are at the same rate. Cold water should not be poured on the hot panel. Otherwise thermal shock may occur. Panels may become unusable.

Figure 2. Solar Panels After Thermal Shock

Brushes used for cleaning should not damage the panel surface. During panel cleaning, the panel should not be stepped on and should never be walked on. Due to the weight of the human body, small, invisible cracks may occur on the panel. Serious problems, especially electric shock, may occur due to rainwater leaking into cracks or liquids used for cleaning. Abrasive or hard brushes can scratch the delicate anti-reflective coating on the surface of the panel. These scratches, no matter how small, can scatter incoming sunlight, reducing the amount of light absorbed and converted to electricity. If the brush leaves streaks or debris behind, these act like tiny shadows on the cells and block some of the incoming sunlight, reducing overall power production.
