Abstract
This project is conducted at the main campus of Universiti Teknikal Malaysia Melaka (UTeM), Melaka. The changes of weather and passing cloud may caused variation of solar irradiation that contributed to variation of PV output power. Unfortunately,the variation of PV output will cause energy losses and harmonic distortion. Thus, the aim of this project is to study the correlation between solar irradiance and Total Harmonic Distortion (THD) contributed from PV inverter and investigate the efficiency of PV inverter with variation of solar irradiance. Fluke 43B meter and Automatic Weather Monitoring System(AWS) were used to record the required data. The data was collected for 3 to 6 months in order to analyse the data. In addition, the value of THDi, current, solar irradiance,output and input voltage have been recorded for 8 hours a day for 30 days.From the collected data, its shown that the variation of solar irradiance effects the THDi and current profiles. When the solar irradiance is high the value of current also increase. However, THDi increases when the solar irradiance is low. This implies that, in order to get high power quality of output, the value of solar irradiance should be high. Based on the result, it shows that the average value of THDi fulfil the requirement from TNB Technical Guidebook. Furthermore, the inverter efficiency is high when the DC power output is high.Low and fluctuating DC power output cause the value of inverter efficiency to decrease. In addition, the value of solar irradiance give impact to inverter efficiency.The finding shows that the of solar irradiance, DC power output and efficiency have the same behavior.
