Engineering Contradiction Analysis
1Ease of operation
If human technicians are used for maintenance and repairs in large solar farms, then tasks can be performed with human judgment and adaptability, but the operations become inefficient and costly
Solution Approach 1:
The solar panel cleaning robot autonomously navigates to solar panels, identifies dirty areas using sensors, and performs cleaning operations without human intervention. The system self-manages the entire maintenance process from detection to execution, eliminating the need for human technicians to physically perform cleaning tasks while maintaining high operational efficiency.
Solution Approach 2:
The patent replaces human mechanical operations with an automated robotic system equipped with specialized cleaning mechanisms. The robot uses mechanical arms with cleaning elements (such as brushes or wiping elements) that are controlled by automated systems, substituting human physical labor with machine-based operations to improve efficiency and reduce costs.
2Productivity
If robots are deployed for autonomous maintenance tasks, then productivity and scalability are improved, but device complexity increases
Solution Approach 1:
The robotic system is designed with multiple functions integrated into a single platform: navigation, inspection, cleaning, and data collection. The robot can perform various maintenance tasks on different solar panel configurations and can adapt to different cleaning requirements, reducing the need for multiple specialized devices and thereby managing complexity while maintaining high productivity.
Solution Approach 2:
The robotic system is divided into modular components that can be independently developed, tested, and maintained. Each module (navigation system, cleaning mechanism, sensor array, power system) can be optimized separately and replaced or upgraded independently, which manages overall system complexity while enabling high productivity through specialized subsystems.
3Productivity
If specialized cleaning tools are used on solar panels, then cleaning effectiveness is improved, but the risk of panel damage increases
Solution Approach 1:
The cleaning system dynamically adjusts operational parameters such as contact pressure, cleaning speed, and tool engagement force based on real-time sensor feedback about panel condition, dirt level, and environmental factors. This ensures effective cleaning while preventing excessive force that could damage the panels, thereby maintaining both cleaning effectiveness and panel safety.
Solution Approach 2:
The robotic cleaning system incorporates sensors that continuously monitor panel conditions during cleaning operations. The system uses this feedback information to adjust cleaning intensity, detect potential damage risks, and modify its behavior in real-time, ensuring effective cleaning while minimizing the risk of panel damage through closed-loop control.

AI summary
The solar energy and solar farms are used to generate energy and reduce dependence on oil (or for environmental purposes). The maintenance, operation, optimization, and repairs in big farms become very difficult, expensive, and inefficient, using human technicians. Thus, here, we teach using the robots with various functions and components, in various settings, for various purposes, to improve operations in big (or hard-to-access) farms, to automate, save money, reduce human mistakes, increase efficiency, or scale the solutions to very large scales or areas, e.g., for repair, operation, calibration, testing, maintenance, adjustment, cleaning, improving the efficiency, and tracking the Sun.
