Abstract:

Despite significant advancement in PV technology and efficiency, qualification testing and market penetration, actual performance in the field of operation under a myriad of environemental constraints remains an important topic. PV arrays are subject to degradation mechanisms that can significantly impact power production capability. For revenue-critical PV arrays, detection of underperformance and its timely resolution are therefore essential for the cost-effective operation and optimal integration with the Smart Grid. This proposal will develop a cloud-based diagnostic infrastructure in which services are provided to PPA contractors which enables real-time monitoring and diagnostics of the PV array.: Our Phase I accomplishments include developing a detailed modeling simulation tool that models hotspot generation due to shading, dusting, and intrinsic component mismatch. Additionally, we developed a model based diagnostic algorithm that is able to predict degradation events. Our phase II plan will (1) develop and test the PV modeling tool for numerous degradation mechanisms, (2) develop the framework for a dynamically updated database of major PV manufacturer models, (3) develop Model based Diagnostic Algorithms, (4) experimentally evaluate the model and diagnostic algorithms, and (5) investigate demand response concepts that utilize real-time PV diagnostics and smart meter data. . Commercial Applications and Other Benefits: The solar power integrators have struggled with four issues for some time: Under-performance (losses), lack of full monitoring, fire and maintenance safety, and module theft. These products and services all require major paradigm changes, or need to be redesigned which is more difficult to justify. Wattminder
