Yes, dust can indeed affect solar panels. Dust particles can accumulate on the surface of solar panels and obstruct sunlight, thereby reducing the panels' efficiency and energy output.
The effect of the accumulation of dust on the surfaces of PV panel has been studied with extreme concentration because of its great importance, especially in the countries located in the solar belt zone and its surroundings, which are mostly desert countries.
Do solar panels lose power due to dust?
Interestingly, most research has reached a consensus that solar panels can lose up to 40-50% power due to dust accumulation. [2,6,7] It is also important to note that other variables can affect the impact of dust settlement on solar panels, and they include humidity, size of dust particles, wind, and tilt of the solar panel.
The amount of dust that accumulates on the panel varies geographically. For example, an experiment performed in Tehran, Iran shows that the dust concentration on a local solar panel (accumulated over a period of 70 days) ranges from 4.0599 g/m 2 to 10.3129 g/m 2.
Why do solar panels need dust?
One of those challenges is dust accumulation on the solar panel, which acts as a layer of shade preventing sunlight from penetrating the cell and being converted to electrical current.
How does accumulated dust affect a solar PV system?
The characteristics of the accumulated dust (type, size, shape, meteorology, etc.) are determined by its geographical source, and its effect is not only to reduce the solar radiation reaching the surface of the PV, but also to adhere to these surfaces and scratched and work on corrosion and reduce their life span.
Does dust affect PV panel performance?
Dust is one of the essential parameters that affect PV panel performance, yield, and profitability. However, the dust characteristics (type, size, shape, meteorology, etc.) is geographical site specified. Many researchers investigated PV panel dust cleaning and mitigation methods.
