A PV module has been tested using a steady$-$state solar simulator, and the following I$-$V and PV curves have been measured:

Assume that the module is now connected to a charge controller, and the irradiance and temperature of the module remain the same as during the test.

A$)$ If the Fractional Open Voltage method is implemented in the charge controller assuming that $\backslash ($ V$\_\{$M P P$\}\backslash )$ is $\backslash (70[\backslash \%]\backslash )$ of $\backslash ($ V$\_\{$O C$\}\backslash ),$ what is the operating voltage of the panel? Give the answer in $\backslash ([\backslash$mathrm$\{$V$\}]\backslash )$ and with one decimal place.

B$)$ If the Short Current Pulse method is implemented in the charge controller assuming that $\backslash ($ I$\_\{$M P P$\}\backslash )$ is $\backslash (92[\backslash \%]\backslash )$ of $\backslash ($ I$\_\{$S C$\}\backslash ),$ what is the operating current of the panel? Give the answer in $\backslash ([\backslash$mathrm$\{$A$\}]\backslash )$ and with one decimal place.

C$)$ Which method is more efficient in this particular case?

The Fractional Open Voltage method.

The Short Current Pulse method.

Both have the same efficiency.

It cannot be determined from the information given.
