An electrostatic self-cleaning panel for solar collectors is described. An electrodynamic screen is formed by inter-digitated, transparent surface electrodes energized by three-phase, low-frequency ac voltages in the range 5 to 200 Hz and 500 to 1000 V. The resulting electrostatic field wave exerts force on the particles and sweeps them laterally across the panel. Particle trajectories are simulated to help ascertain parameters for maximum dust-removal efficiency. The electric field of thedoi:10.1109/tia.2013.2244192 fatcat:3qfczeurpbdxdlxnzprhpw3tla
