Patented technology for dust removal of photovoltaic panels

What is solar dust removal technology?

The technology employs a non-uniform traveling field to generate charge polarization and induce electrophoretic/dielectrophoretic forces, enabling automatic dust removal from the surface of solar panels , , , , .

How do solar panels remove dust?

Here, an autonomous dust removal system for solar panels, powered by a wind-driven rotary electret generator is proposed. The generator applies a high voltage between one solar panel's output electrode and an upper mesh electrode to generate a strong electrostatic field.

Can a self-powered autonomous dust removal system be used for solar panels?

In this work, a self-powered autonomous dust removal system (ADRS) for solar panels is proposed as shown in Figure 1a.

What are electrostatic dust removal systems?

Electrodynamic screens (EDS) are the most popular electrostatic dust removal systems. Some approaches for implementing EDS involve fabricating arrays of interdigitated transparent indium tin oxide (ITO) microelectrodes that are embedded in a dielectric film or installing insulated copper mesh electrodes on top of solar panel surfaces (25 – 28).

Are solar panels dust-free?

Solar panels often suffer from dust accumulation, significantly reducing their output, especially in desert regions where many of the world's largest solar plants are located. Here, an autonomous dust removal system for solar panels, powered by a wind-driven rotary electret generator is proposed.

What is an autonomous dust removal system powered by wind energy?

In summary, an autonomous dust removal system powered by wind energy has been developed. The ADRS comprises a REG, a VMC, and DRUs. The REG with VMC harvests wind energy to provide a high DC voltage between an upper mesh electrode and one of the output electrodes of the solar panel to generate a strong electrostatic field.
