A comprehensive analysis of the electric field distribution in an electrodynamic screen

• Two EDS configurations with two layers of dielectric coatings have been considered.
• Comprehensive analytical expressions for the electric field have been provided.
• Analytical solutions have been corroborated using finite element analysis software.
• Two EDS configurations have been compared with respect to dust removal efficiency.

The electrodynamic screen, or EDS, has shown promising results in mitigation of dust accumulation losses in solar energy harvesting systems. In this paper, the electric field distributions in two EDS configurations have been thoroughly investigated. The analytical solutions for the electric potential and electric field distribution in the first EDS configuration have been provided and corroborated numerically using finite element analysis (FEA) software. The electrostatic model of second EDS configuration has been developed in the FEA software and its electric field distribution has been analyzed numerically. A comparison has been made between the two configurations regarding dust removal efficiency.
