Best performing PV module

The task for this section is to pick the best performing PV module from a range of available modules, by calculating their efficiency. The input for this task is provided in a data file.

It contains specifications of five PV modules at standard test conditions $($STC$).$

The data of the PV modules is again given in $.$mat format:

$-$ 'PVData.mat' file is easier to import it in Matlab $($link$).$ If you are using Matlab you are supposed to import the variables from the $\text{'}.$mat' files. To import the PV module data from the file in the Matlab environment we use the function load$()$ as in line $2.$

Note, for this task you are required to store your output result under the variable name max$\_$Eff in percentage $(\backslash \%)$ value.

Further this task is a graded section. After you have completed your MATLAB simulation and obtained the output result, you have to answer the questions provided below the MATLAB section based on your simulation output.

$```$

$\%$ Load the PVData.mat file containing the cell array 'PVModule'.

load$(\text{'}$PVData$.$mat','PVModule'$)$;

$\%$ 'PVData.mat file contains the cell array 'PVModule'. The cell array 'PVModule' contains five structures.

$\%$ Each structure contains of six fields, namely: Voc, Isc, Vmpp$,$ Impp, Length and Width

$\%$ As an example we calculate the fill factor for all the PV modules.

$\%$ The index $\{$i$\}$ refers to the number of the structure that contain all the PV modules

$\%$ And the $\text{'}.$Vmpp$\text{'}$ refers to the field in the chosen structure

modules$\_$count $=$ length$($PVModule$)$; $\%$Number of modules

FF $=$ zeros$(1,$modules$\_$count$)$; $\%$Create an empty array to store the FF values

for i $=1$:modules$\_$count $\%\text{'}$ i$\text{'}$ is the index to iterate through vector $\text{'}$FF$\text{'}$ for the five PV modules

FF$($i$)=100*$ PVModule$\{$i$\}.$Vmpp$*$PVModule$\{$i$\}.$Impp $/($PVModule$\{$i$\}.$Voc$*$PVMModule$\{$i$\}.$Isc$)$; $\%$Calculate each FF value

end

$\%$ Find the PV Module with the highest fill from factor from the list.

$[$max$\_$FF$,$idx$\_$FF$]=$ max$($FF$)\%$ The maximum fill factor and its index in the cell array are displayed

Eff $=$ zeros$(1,$modules$\_$count$)$;

$\%$ Remember the efficiency must be expressed as a percentage!

for $...$

end

$\%$ Pick the PV Module with the highest efficiecny from the list.

max$\_$Eff $=...$

Assessment:

This assesment test's whether the best performing PV module efficiency is calculated correctly? Make sure your output result is given in percentage $(\backslash \%)$ value.
