As the 100W bendable solar panel is exposed outdoors for a long time, a lot of dust accumulates on the panel. Dust has a significant impact on the 100W bendable solar panel. It not only has a certain influence on the power generation efficiency, but also corrodes the panel glass, resulting in a shortened lifespan. Now, let's have the editor introduce to you the necessity of cleaning the 100W bendable solar panel.

I. The Influence of Dust on 100W bendable solar panel

1. Output performance has declined

During the operation of solar photovoltaic power generation systems, they are affected by the dust in the environment where they are located. The photoelectric conversion efficiency of photovoltaic cells is related to the intensity of solar radiation. Dust accumulation on the surface of photovoltaic panels will reduce the light transmittance of the front cover glass. The decrease in light transmittance will lead to a decline in the output performance of the cells. The higher the deposition concentration, the lower the light transmittance, and the less radiation absorbed by the panels, resulting in a greater decline in their output performance.

2. Battery efficiency loss

During periods of scarce rainfall, due to the accumulation of dirt on the panel surface, the battery efficiency loss can reach over 15%. The dirt and dust on the panel surface can reduce the average annual power generation efficiency by 6%. Generally speaking, the dust and dirt in the air include: dust, rainwater and pollutants. Their presence will lead to a reduction in the output energy of the battery. Because dust particles have a significant impact on the forward scattering of sunlight, the current loss of this centralized module is usually much higher than that of the non-centralized one.

3. The panel temperature rises

Most of the existing photovoltaic power stations use silicon-based solar cells, which are highly sensitive to temperature. When a certain thickness of dust accumulates on the surface of the panel, it will cause an increase in its heat transfer thermal resistance, which has an insulating effect on the panel and affects its heat dissipation function. Dust adhering to the surface of the panel blocks the outward transfer of heat, which may prevent the panel's own heat from being released, causing the temperature to keep rising and affecting the efficiency of photovoltaic power generation.

4. Corrosion of solar cell panels

The composition of dust is rather complex, with some being acidic substances and others alkaline ones. The main components of crystalline silicon photovoltaic panels are silicon dioxide and limestone, etc. If dust comes into contact with water vapor in the air and becomes moist, it can undergo acidic or alkaline reactions with the constituent substances of the panels. After a period of time, the surface of the photovoltaic panel gradually undergoes corrosion and damage under the erosion of acidic or alkaline environments, making it pitted and uneven. This leads to a decline in the optical performance of the photovoltaic panel, causing diffuse reflection of solar radiation on the panel surface and disrupting the uniformity of solar radiation propagation within the photovoltaic panel.

Ii. Precautions for Cleaning 100W bendable solar panel

Regularly observe the solar cell array. When the dust on the surface of the solar cell array turns gray and the original blue crystalline plate surface of the solar cell array cannot be seen clearly, the solar cell array should be cleaned and dusted in time.

2. To prevent electric shock injuries to people and possible damage to the solar cell modules from wiping the solar cell array under high temperatures and strong sunlight, the module cleaning work should be carried out in the morning or late afternoon.

3. Previously, when answering for everyone how to correctly clean the 100W bendable solar panel, it was mentioned that when cleaning the glass surface of the solar cell module, use a soft brush, clean and mild water, and apply a small amount of force during cleaning to avoid damaging the glass surface. For modules with coated glass, be careful not to damage the glass layer.

4. If it is dry dust, it can be removed with a feather duster. If it is grease, just wipe it clean with water and a mop. If the oil stains are severe, they can be removed with an appropriate amount of alcohol and a soft cloth. Do not rinse or wipe with hard objects or corrosive solvents.

5. Solar cell modules do have a certain load-bearing capacity, but one must not step on them to clean, as this may cause damage to the solar cell modules or affect their lifespan.

The above is an introduction to the necessity of cleaning the 100W bendable solar panel. There are also many points to note when cleaning the 100W bendable solar panel. The frequency of cleaning in winter should be higher than that in summer, and anti-freezing measures should also be taken.
