Abstract

Data-Acquisition systems are widely used in Photovoltaic(PV) system application in order to analyze and optimize the performance of PV systems. In this paper, the development of a computer-based data-acquisition system and its application are described. The proposed Computer-based data-acquisition System consists of a set of sensors for measuring both environmental and electrical parameters. The collected data are first conditioned and then interfaced to PC using a data-acquisition card. The Labview program was used to further process, display on the monitor at real time and store on the hard disk. We designed and installed two stand-alone PV systems to supply different loads, which in this case a Low Pressure Sodium(LPS) 55 [W] lamp and a electrodless 55 [W] lamp. When the proposed data acquisition system is applied on the designed PV systems, Optimized system operation methods are investigated to confirm a stable load availability and extend battery life time.
