How to prevent dust from accumulating on photovoltaic modules?

The best materials for preventing dust from accumulating on photovoltaic include waterproof coatings, hydrophobic coatings, and anti-static coatings. These materials work to either repel dust away from the solar modules or create a barrier that traps dust before it can reach the modules.

Can nano-coating thin film reduce dust accumulation on PV panels?

Scientific Reports 14, Article number: 23013 (2024) Cite this article Dust accumulation on photovoltaic (PV) panels in arid regions diminishes solar energy absorption and panel efficiency. In this study, the effectiveness of a self-cleaning nano-coating thin film is evaluated in reducing dust accumulation and improving PV Panel efficiency.

What happens if dust is deposited on Photovoltaic Glass?

In addition, dust deposition will also cause damage to the coating applied to the photovoltaic glass. Goossens and Van Kerschaever (1999) reported that the fine dust deposited on the photovoltaic glass causes permanent damage to the anti-reflection coating.

Does dust deposition affect photovoltaic panels?

Vivar et al. (2010) found that the output efficiency of photovoltaic panels decreased by 26% after 4 months. In addition, dust deposition will also cause damage to the coating applied to the photovoltaic glass.

Are anti-dust solar panels a problem?

A lot, according to LONGi’s research. Anti-dust modules and anti-soiling solar panel coatings are not new, but LONGi’s research and testing indicated that more could be done. The “ 2022 LONGi Global Customer Satisfaction Survey Report ” shows that 80.13% of residential and C&I scenarios are troubled by module dust accumulation.

Can dust damage PV panels?

In addition to performance losses, dust accumulation may cause other damages to PV panels. Examples are surface damage due to sand erosion and permeability reduction which will contribute to additional deterioration in the performance of PV panels (Tagawa 2012).
