Photovoltaic System Reliability

Research in photovoltaic system reliability investigates the long-term performance and durability of solar energy technologies. This work examines factors influencing the degradation of solar cells, modules, and balance-of-system components under various environmental conditions. Investigations include material science approaches to understand failure mechanisms, electrical characterization to assess performance changes, and advanced modeling techniques to predict lifespan and identify potential weaknesses. Specific areas of focus include the impact of weather, soiling, and operational stress on photovoltaic output and the development of diagnostic tools and mitigation strategies to enhance system resilience.

This research holds particular relevance for Arkansas as the state seeks to expand its renewable energy infrastructure. Reliable photovoltaic systems are crucial for reducing energy costs for businesses and residents, supporting the agricultural sector through on-farm solar installations, and contributing to the state's energy independence. Understanding and improving the longevity of solar technology can also foster job growth in the installation, maintenance, and manufacturing sectors within Arkansas, aligning with economic development goals.

This field draws upon expertise in semiconductor materials, device physics, materials science, and mechanical properties of thin films. Connections are also made to machine learning and neural network applications for performance monitoring and predictive maintenance, as well as the integration of renewable energy sources into the broader power grid. This research is pursued across multiple Arkansas institutions, reflecting a broad base of engagement.
