Case 13794

Self-cleaning Parabolic Trough for Concentrated Solar Power Systems


Concentrated Solar Power Systems (CSPS), Dust Removal, Parabolic Trough, Vortex Induced Vibration (VIV)


Clean, renewable, and transportable energy conversion/storage


Dust settles out of the atmosphere and deposits onto the reflector surface, degrading the performance of solar systems.


The new parabola panel design combines the cleaning strategies of the natural direct cleaning method by wind effect and the cleaning by wind vortex induced vibration (VIV) method. Addition of geometrical features for the panel will control the air flow velocity across the panel surface and control the VIV.

  • Reduce maintenance costs
