A unique model of Characterization & performance estimation of various solar photovoltaic cells/modules using Microcontroller

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 I
_mp
and voltage V
_mp
at the maximum power point and the I
_SC
and V
_OC
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 V
_OC
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 I
_SC
and V
_OC
points from the I-V curve plotting using ATMEGA Microcontroller.
