Investigation of Photovoltaic System Parameters Using LabView in Solar Irradiance Peak Condition

Abstract

The monitoring of electrical and system parameters such as current, voltage, power, intensity of light, battery, and load in photovoltaic panel is shown in this paper. The system was monitored using LabView Virtual Instrument and NI-DAQ 6008 hardware which are both developed by National Instrument. The parameters of photovoltaic was monitored under solar irradiance peak condition in local area. The system of photovoltaic panel with using monocrystalline and polycrystalline material, each PV have 50 Wp maximal output which is installed as parallel. The PV system is using battery charge regulator to reduce and control the over voltage to the battery. The analysist of the monitoring result is very useful to optimize the parameters and the efficiency of the system. Moreover, it could check the charge controller performance to reduce the over cost which is known as environmental protection. This project will be useful for continuos real time monitoring of solar power plant.
