Photovoltaic (PV) power generation has become one of the key technologies to reach energy-saving and carbon reduction targets. However, dust accumulation will significantly affect the electrical, optical, and thermal performance of PV panels and cause some energy loss.
Dust causes the photovoltaic performance to deteriorate. The main dust components concentrations vary from one geographic location to another and from one season to another. These components also have different effects on the PV power losses.
As some brands cut corners on product quality to remain price-competitive, solar panels start to fail in the field before their expected lifetime is up. Here are 11 of the most common solar panel defects to watch out for in a solar installation, and how WINAICO works to prevent them from happening to your sites.
A significant increase in the density of short circuit current by 3.1% was achieved through applying a self-cleaning cover made of microcone-textured fluorinated ethylene propylene (FEP) on the front surface of PV panels (Roslizar et al. Citation 2020). The additional cover has self-cleaning properties and can decrease the irradiance reflection .

6 FAQs about [Causes of dents on photovoltaic panel surface]
Why do photovoltaic panels have dust particles on the front surface?
The findings of the research can be summarised as follows: 1. Dust particle deposition on the front surface of the photovoltaic panel is not linearly dependent upon the duration of exposure, but it is a complex phenomenon which is influenced by all-weather parameters, among others.
What affects the deposition rate of dust on PV panels?
The deposition rate of dust on the PV panels' surface is heavily influenced by their surface properties, which can vary depending on the material used . Surfaces that are coated tend to have a lesser impact on dust deposition compared to uncoated surfaces .
How does dust affect PV panels?
The findings revealed that the presence of small-sized dust resulted in a significant reduction of up to 49.01 % in the zero resistance current of the PV panels, whereas for large-sized dust (ranging from 600 μm to 850 μm), the reduction was 15.68 %.
How does particle deposition affect the performance of solar photovoltaic panels?
The particle deposition on the surface of solar photovoltaic panels deteriorates its performance as it obstructs the solar radiation reaching the solar cells. In addition to that, it may cause overheating of the panels, which further decreases the performance of the system.
How does dust affect photovoltaic power generation?
Photovoltaic (PV) power generation has become one of the key technologies to reach energy-saving and carbon reduction targets. However, dust accumulation will significantly affect the electrical, optical, and thermal performance of PV panels and cause some energy loss.
How do solar panels affect dust accumulation?
Oh et al. studied how the temperature gradient between solar panels and the surrounding air affects the accumulation of dust, which is called the thermophoresis effect.
