VoltaWash offers an automated robotic cleaning service for photovoltaic modules, employing a truck‑mounted robot with non‑abrasive brushes and reverse‑osmosis water to remove dust, pollen, and sand without harming panel surfaces. The system provides uniform, water‑efficient cleaning and delivers performance reports that quantify energy recovery for utility‑scale, commercial, and agricultural solar installations.

Problem
Dust, pollen, and sand accumulation on photovoltaic modules reduces their energy conversion efficiency, leading to measurable production losses. Conventional cleaning methods often require manual labor, high water consumption, or abrasive techniques that can damage panel surfaces, especially for large‑scale or hard‑to‑reach installations.
Solution
VoltaWash delivers an automated robotic cleaning service that eliminates the need for manual scrubbing while preserving panel integrity. The system uses a German‑engineered robot equipped with non‑abrasive brushes and a reverse‑osmosis water circuit that provides 0 ppm purified water, heated on‑site to enhance degreasing. Mounted on a truck‑borne aerial platform, the robot can traverse both ground‑mounted and rooftop arrays, delivering consistent cleaning coverage in a single pass. By minimizing water usage and avoiding abrasive contact, the service restores panel performance and extends module lifespan. Clients receive post‑cleaning performance reports that quantify energy gain, enabling data‑driven maintenance planning.
Target Audience
Primary customers are utility‑scale solar farm operators, commercial solar installers, and agricultural enterprises that own rooftop or ground‑mounted photovoltaic installations.
Features
