Preliminary development of data acquisition system of solar energy assessment

Abstract

Performance, quality and reliability issues are becoming more and more important for the emerging photovoltaic market world. A computer based data acquisition system to collect and monitor photovoltaic power generation system using Aduino has been design and implemented in fish house. Prior to designing the data acquisition system, a small sized PV power generation system, consisting of 8 module of PV panel, a charger controller and a DC to AC inverter, has been assembled. At the same time, Data-acquisition systems are widely used in renewable energy sources (RES) application in order to collect data regarding the installed system performance, for evaluating purposes. In this study, the development of a computer based system for RES system for collecting data is described. The data analysed here are derived from analytical monitoring data, hourly values and 15-minute- value in 24 hours. The proposed system consists of a set of sensor for measuring both meteorological (temperature sensor and ambient light sensor), storage data (microSD card) and electrical parameters (photovoltaic voltage and current).
