Abstract
In this study, a novel electrostatic cleaning scheme has been applied to a new designed and developed electrode having high cleaning efficiency. In this method, a high voltage, four-channel, 1 Hz square wave signal is applied to a specially designed electrode array. Models of the electric field distribution of the proposed electrode array were developed and analyzed using Ansys Maxwell simulation software and printed circuits boards (PCBs) were produced. The performance of dust removal using the electrodes was evaluated. A 1 MW solar power plant was taken as a case study, and performance and cost were compared with the classical panel cleaning method (wet cleaning system). Our study has shown that the electrostatic cleaning method can be carried out with lower cost and higher efficiency than existing methods.
Highlights
The power produced by solar panels varies according to the incident radiation, which varies with location, climate, and installation
The effects of dust accumulation have been investigated in detail and the cleaning cycle and methods based on the PM10 world map for dust removal are discussed in [3]
This study proposes a design for the electrodes of an electrostatic cleaning system that will reduce the contamination caused by atmospheric transported particulates on a solar panel
Summary
The power produced by solar panels varies according to the incident radiation, which varies with location, climate, and installation. The electrostatic method is based on cleaning dust by applying high voltage to parallel electrodes embedded in the glass plate of the panels [21]. It has been found that an electrodynamic cleaning system can achieve a reduction in dust pollution between 32.1% and 95.7% [35] This can provide efficient operation for large-scale SSP built in deserts around the world [34] and may be used to remove dust from solar visors, and surfaces such as solar panels on extra-terrestrial missions [26,29,30,33,36,37,38,39].
