Under the current drive for “dual carbon” targets, centralized ground photovoltaic power stations have become the mainstay of renewable energy development. However, their vast land area and densely arranged components (such as those in large desert or Gobi power stations) face significant challenges due to dust, bird droppings, and other contaminants. For example, a 10% accumulation of dust can lead to a decrease in power generation efficiency by up to 30%, resulting in substantial energy loss.
Traditional cleaning methods, such as manual labor or high-pressure water trucks, are inefficient and costly due to labor scheduling and water resource consumption. They also pose safety hazards during high-altitude operations and can damage the coating of components, leading to hidden cracks. To address these issues, the centralized ground photovoltaic power station cleaning robot has emerged as a core solution for smart operation and maintenance (O&M). It efficiently removes dust to ensure the stable operation of the power station and significantly enhances profitability. This article will comprehensively analyze its value, working principles, selection strategies, and market prospects, helping power station managers achieve cost reduction and efficiency improvement.
Why Are Photovoltaic Cleaning Robots Necessary?
The core value of cleaning robots lies in their ability to fundamentally address O&M pain points and bring multiple benefits to power stations:
- Enhanced Power Generation Efficiency: Regular cleaning can increase annual power generation by an average of 5%-25% by preventing degradation caused by dust accumulation.
- Reduced O&M Costs: Robots require only a one-time investment, resulting in low ongoing maintenance costs and enabling “unmanned” operations, thus saving on long-term management expenses.
- Improved Safety: Robots can operate stably in harsh environments, eliminating personnel safety risks associated with high-altitude work.
- Extended Component Lifespan: Utilizing waterless or micro-water dry brushing technology protects the component coatings and structures, reducing the risk of hidden cracks.
Given these advantages, cleaning robots have become essential tools for modern power stations, with ROI typically shorter than expected.
In-Depth Analysis of the Working Principle of Centralized Photovoltaic Cleaning Robots
These robots incorporate several advanced technologies to ensure efficient and intelligent cleaning. The core technological components include:
- Intelligent Navigation and Positioning System: Integrates GPS, BeiDou, inertial navigation, and machine vision for centimeter-level precise movement, avoiding missed or redundant cleaning.
- Autonomous Obstacle Crossing and Inter-Array Capability: Strong power system and chassis design allow for easy traversal of gaps between support structures.
- High-Efficiency Cleaning System: Uses flexible spiral brush heads for waterless dry brushing, ensuring thorough stain removal.
- Intelligent Control and Cloud Platform Management: Supports remote start, task planning, status monitoring, fault self-diagnosis, and data analysis.
The workflow demonstration is as follows: after receiving instructions, the robot autonomously plans its path, begins cleaning photovoltaic panels, crosses obstacles, and returns to the charging station to upload a work report to the cloud platform, significantly enhancing maintenance efficiency without human intervention.
How to Choose the Right Photovoltaic Cleaning Robot for Your Power Station
Selecting the right cleaning robot requires matching the specific conditions and performance requirements of the power station. Consider the following practical guidance:
- Assess the Environment and Layout: Evaluate terrain (flat deserts, gentle slopes, or complex terrains) and array layout (string lengths, array spacing, type of support—fixed or tracking).
- Examine Key Performance Indicators: Look into cleaning efficiency (in m²/h), endurance and charging methods, environmental adaptability (IP protection rating, operational temperature and humidity), and reliability and after-sales service.
- Conduct a Cost-Benefit Analysis: Calculate the return on investment (ROI) by considering equipment costs, maintenance expenses, and potential power generation increases (5%-25% boost from the robot).
Application Cases and Market Prospects
Showcasing the actual effects and future potential of cleaning robots enhances user trust. Global examples include:
- Large projects in the UAE’s desert power stations, where deploying cleaning robots led to over a 20% increase in annual power generation and a 40% reduction in O&M costs.
- The Northwest Gobi power station in China (Qinghai project), which effectively applied cleaning robots, significantly addressing dust problems and boosting profitability.
As the “dual carbon” goals progress and the scale of centralized power stations expands, intelligent operations and maintenance will become inevitable, and the demand for cleaning robots will continue to grow.
