PROJECT TITLE :

A Unique Model of Characterization & Performance Estimation of Various Solar Photovoltaic Cells/Modules Using Microcontroller

ABSTRACT :

At the end of the solar module manufacturing process, an I-V measurement is performed under different illumination of each individual solar module to determine its current Imp and voltage Vmp at the maximum power point and the ISC and VOC points, where the power will be zero and the maximum value of power will occur between the two. The Fill Factor (FF) is essentially a measure of quality of the solar sell. When calculated the performance of the solar cell from I-V Characteristics using the conventional method, it was found that noise caused the I-V curves to zigzag slightly near the VOC and to zigzag widely near the `knee' of the curve. Defining the exact value of solar Module's parameters is called Module's Characterization. So in this paper the authors are tried to minimized the noise of I-V curve to get the highest power output using Automatic electronic load regulator and also find out a real value of ISC and VOC points from the I-V curve plotting using ATMEGA Microcontroller.
