研究目的
The investigation of the effects of dust soiling on PV module performance and the application of experimental dust mitigation methods, including the use of a hydrophobic anti-soiling coating and the execution of a self-cleaning manoeuvre by the SAT systems.
研究成果
The hydrophobic anti-soiling coating was found to promote dust soiling rather than mitigate it, and the self-cleaning manoeuvre did not yield conclusive results as a dust mitigation method. The study highlights the need for further research into effective dust mitigation strategies for PV modules in semi-arid environments.
研究不足
The study was conducted over a limited period of three months and in a specific geographical location, which may not capture all variations in dust soiling effects and mitigation method effectiveness across different environments and seasons.
1：Experimental Design and Method Selection:
The study involved deploying two SAT systems as experimental platforms to investigate the effects of dust soiling and the effectiveness of dust mitigation methods.
2：Sample Selection and Data Sources:
Data was collected over a three-month period (97 days) from PV modules subjected to the semi-arid Northern Cape environment of South Africa.
3：List of Experimental Equipment and Materials:
Included SAT systems, PV modules, a hydrophobic anti-soiling coating, and an intelligent device for extracting I-V curves.
4：Experimental Procedures and Operational Workflow:
Involved applying the hydrophobic coating, executing self-cleaning manoeuvres, and monitoring weather conditions and PV module performance.
5：Data Analysis Methods:
Utilized a performance ratio (PR) for comparing PV module performances and a single-diode curve fitting routine for validating I-V curve measurements.
