The cleaning methods of photovoltaic modules include manual dust removal, mechanical dust removal, electrostatic dust removal, self-cleaning coating and so on. In general, the self-cleaning coating has better performance in dust removal. It requires no power or manpower, relying on its own characteristics.
The main method of dust removal is manual or machine cleaning with water, but these methods have high costs and low cleaning efficiency [1, 21, 31]. It is worth noting that an improper cleaning process can cause mechanical and corrosive damage to photovoltaic modules. In areas where water is scarce, only mechanical methods can be used [79, 80].
A large number of experimental studies have shown that the cleaning of dust deposition plays a crucial role in improving photovoltaic power generation efficiency . The cleaning methods for dust deposition mainly include manual cleaning, mechanical dust removal, electrostatic dust removal technology, and self-cleaning coating technology.
Understanding the dust deposition characteristics of PV modules can provide theoretical support for selecting dust cleaning methods and formulating cleaning strategies. This paper introduced the factors affecting dust accumulation and presented the research status of dust deposition mechanisms.
Dust is defined as tiny particles suspended in the air with a particle size of 0.1 µm to 1 µm. . Dust deposition can affect the performance of photovoltaic modules . It is necessary to further study the mechanism of dust deposition and investigate the intrinsic effects of dust on PV modules.
Charged dust particles on photovoltaic modules will absorb dust particles in the air, resulting in more serious dust deposition [5, 20, 62]. Liu et al. studied the mechanism and properties of dust deposition on solar photovoltaic modules under electrostatic action. Figure 8 illustrates the principle and mechanism.
