Methods and Techniques for Photovoltaic Solar Power Plant Monitoring and Wearing State Evaluation

The paper presents methods and techniques for monitoring the status and diagnosis of wear for each element in the architecture and operation of photovoltaic solar power plant. A typical configuration of photovoltaic solar power plant is: photovoltaic panel, junction box, connection cables, controller, battery and inverter. The first part of this study describes the methods and techniques often used in monitoring and diagnosing the state of a system. In the second part of the study is presented a new method and technique used in monitoring and diagnosing the state of a system, SMART FMECA. This new method will help to approach a better hierarchy of each failure mode, for each component.
