Multi-Sensor Detection and Autonomous Cleaning for Solar Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional smoke detectors fail to differentiate between dust and smoke, leading to false negatives in detecting cigarette smoke, and there is a lack of sensors to monitor and clean solar panels, HVAC ducts, and other objects for dust, dirt, snow, and ice, resulting in poor indoor air quality and reduced efficiency of solar panels.
Innovation Solution
A system comprising sensors (cameras, thermal cameras, infrared, and ultrasonic sensors) and processors that detect dust, dirt, snow, and ice on solar panels and other objects, which can autonomously clean these surfaces using drones or robots, and communicate cleaning needs via wireless interfaces, employing machine learning for image-based cleanliness assessment and using cleaning formulations with catalysts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional smoke detectors are used to detect cigarette smoke, then fire safety is maintained, but the detectors cannot distinguish cigarette smoke from dust and water vapor, resulting in false negatives
Solution Approach 1:
The patent segments the detection function into multiple specialized sensors (infrared sensor for cigarette smoke, ultrasonic sensor for dust, optical sensor for water vapor) rather than using a single conventional smoke detector. This segmentation allows each sensor to specialize in detecting specific substances, thereby improving measurement precision while maintaining reliability through the coordinated work of multiple sensors.
Solution Approach 2:
The system employs a multi-functional detection platform that can detect multiple types of substances (cigarette smoke, dust, water vapor, solar panel dirt) using different sensing mechanisms. This universal detection system replaces the need for separate specialized devices while improving overall detection accuracy through the use of appropriate sensors for each target substance.
2Reliability
If manual cleaning of solar panels is performed, then cleaning effectiveness is ensured, but it requires human intervention and is unsafe when panels are on rooftops
Solution Approach 1:
The system enables solar panels to be cleaned automatically without human intervention. A drone equipped with cleaning mechanisms autonomously navigates to the solar panels and performs cleaning operations based on dirt detection data. This self-service approach maintains cleaning effectiveness while eliminating the safety risks associated with human workers accessing rooftops.
Solution Approach 2:
The patent replaces manual mechanical cleaning with an automated drone-based system. The drone uses mechanical arms, brushes, or spray mechanisms mounted on an autonomous platform to clean solar panels, substituting human physical labor with automated mechanical systems that can safely operate at heights.
3Manufacturing precision
If professional duct cleaning services are hired, then cleaning quality is ensured, but it increases cost and requires coordinated scheduling
Solution Approach 1:
The system incorporates continuous monitoring of HVAC ducts using sensors that detect dust and particle levels in real-time. When pollution thresholds are exceeded, the system automatically notifies users and schedules cleaning operations. This feedback mechanism ensures cleaning quality is maintained based on actual conditions while simplifying service coordination through automated scheduling and notification systems.
4Object-affected harmful factors
If indoor air quality monitoring is not implemented, then system complexity is reduced, but health risks from pollutants increase
Solution Approach 1:
The system uses a universal multi-functional platform that combines air quality monitoring, pollutant detection, and automated notification capabilities. A single integrated system monitors multiple pollutants (particulate matter, VOCs, carbon monoxide) using various sensors, reducing the need for multiple separate devices while comprehensively addressing health risks from indoor air pollution.
