6 FAQs about [What to do if there is too much dust on photovoltaic panels]
How to remove dust from PV panels?
Sometimes, special cleaning agents are mixed with high-pressure water to enhance dust removal efficiency , , . Additionally, the presence of water helps cool the PV panels , . However, this method is not suitable for semi-arid and arid regions facing severe water scarcity .
How to clean solar panels in a dusty environment?
Electrostatic cleaning Electrostatic cleaning is one of the prominent methods towards solar panel cleaning in a dusty environment. The concept has been developed with a high AC voltage which is applied to the electrodes deployed on the soiled solar panels to remove dust.
Does dust affect the performance of PV panels and cleaning methods?
Many researchers have reviewed the effects of dust on the performance of PV panels and cleaning methods, but their coverage is narrow and lacks more in-depth summarization, comparison, and critique of key quantitative results.
How to remove dust from solar panels?
A damp cloth or soft brush could be used to gently remove any dirt or dust from the module. As an example, reference (Lasfar et al. 2021b) studied the influence of dust deposits on PV solar panels in Mauritania. The results showed that dust deposits decreased the power output of photovoltaic solar panels by 4.3% over a period of 1 month.
Can a vacuum blower clean the dust from PV panels?
The work in Akbar and Ahmad (2019) proposes a vacuum blower for cleaning the dust from the PV panels. The power source for the blower is a battery which is charged by the PV panel. After cleaning the panel using the method proposed, it showed that the efficiency of the panel improved by 18%–20%. It does not do any wastage of water.
How to remove dust from PV modules?
These methods include super-hydrophilic film, super-hydrophobic film, electrostatic removal of dust, etc. Problems of dust and ice accumulation and its cleaning technologies for PV modules are also discussed. The limitations of Gaofa et al. (2011) is dust accumulation factors, impact analysis and mathematical model are not addressed.
