Solar Panel Cleaning

— Robot-Based Large-Scale Photovoltaic Cleaning Solution

1. Application Background

During long-term operation, photovoltaic modules are continuously exposed to environmental contamination such as dust, sand, bird droppings, industrial particles, and rainfall residues.

These contaminants accumulate on glass surfaces, reducing light transmittance and affecting energy generation efficiency.

Traditional cleaning methods rely on manual labor or simple tools, which are inefficient, costly, and difficult to scale for large solar farms.

2. System Overview

This solution is centered on an automated cleaning robot system  designed for photovoltaic plants.

The system enables autonomous, path-based cleaning of solar panel arrays through ground-based mobile robots, achieving large-scale and standardized cleaning operations.

The system includes:

Autonomous solar cleaning robots

High-pressure cleaning and brushing modules

Ground water supply system

Remote control and management platform

Cleaning data analytics system
