PROVISIONAL PATENT APPLICATION

Title: Self-Cleaning Solar Panel

FIELD OF THE INVENTION

[0001] The invention relates to the maintenance of photovoltaic solar panels.

BACKGROUND

[0002] Dust and soiling on solar panels can cut energy output by 20% or more.

[0003] Existing solutions rely on water and manual labor, which are costly, scarce in deserts, and risk damaging the panel surface.

SUMMARY OF THE INVENTION

[0004] An invention is disclosed for a solar panel with an electrostatic dust-repelling surface that cleans itself without water or moving parts.

DETAILED DESCRIPTION

[0005] The panel includes a transparent electrode mesh embedded beneath an anti-reflective coating on the cover glass. A controller applies a periodic alternating voltage to the mesh, generating a travelling electrostatic wave across the surface. The wave lifts charged and neutral dust particles and transports them toward the panel edge, where they fall away under gravity — without water, brushes, or moving parts. The controller schedules cleaning cycles at dawn to minimize energy draw, and a photodiode senses output so that an on-demand cycle triggers whenever soiling reduces power beyond a threshold.

CLAIMS

1. A self-cleaning solar panel comprising a transparent electrode mesh and a controller configured to apply a travelling-wave voltage to the mesh.

2. The panel of claim 1, wherein the controller triggers a cleaning cycle based on a measured drop in output.

ABSTRACT

A solar panel that repels dust electrostatically via a travelling-wave voltage applied to a transparent electrode mesh, maintaining output without water or moving parts.

This is a drafting aid, not legal advice, and not a USPTO filing. You still file via Patent Center with the official cover sheet (form SB/16) and fee. A provisional only protects what it describes — and an attorney's review before you rely on it is money well spent. PatentBrief is not a law firm.
