In this study, shadowing was first performed on the solar module; however partial shadowing of solar module with series connected cells resulted in different area-current and area-voltage variations for each different geometric shape.
The same areas are represented by different current and voltage values for different geometric shapes. Shadowing of
one of the series connected cells completely or more than the others decreases the cell current and consequently the solar
module’s output current and thus results in a sudden decline in shadowing-current relationship. This outcome of partial
shadowing effect on series connected cells were observed by making current and voltage measurements; thus it was
concluded that this method of procedure could not be an appropriate approach for leaf area measurement.
