An Overview of Remote Monitoring PV Systems: Acquisition, Storage, Processing and Publication of Real-Time Data based on Cloud Computing

Abstract:

Renewable energy sources (RES) are regard as an important alternative for significantly contributing to the sustainable energy supply in the world. Photovoltaic (PV) systems generate electricity from solar radiation. They are one of the most emerging RES technologies due to their continuous technological progress and their constant cost reduction. Monitoring PV systems is necessary to provide information that allows their holders to maintain, operate and control these systems, reducing installations costs and avoiding unwanted electric power disruptions. This paper presents an overview of remote monitoring solutions for PV installations along with the main proposals, commercial products and international experiences proposed in the literature. The paper is focused on three main features: i) consumption of data measuring and recording devices, ii) high storage requirements for certain conditions of data logging frequency or historical data series register, and iii) proprietary software provided by solar manufacturers. Furthermore, a detailed review of cloud-based platform for monitoring of PV systems is present. This review focuses on real experiences based on following features: i) low consumption wireless sensors to gather real-time information, ii) extreme scalability of the system, iii) huge amount of information (real-time data and periodic reports) to process, store and publish, and iii) a set of open source e-services and web applications. Finally, a proposal of new architecture for isolated PV monitoring systems in Ecuador is described.
