In the simulations, it can be concluded that the system at steady state is most efficient when the hydrogen
electrolyser together with the PV array is enabled in a closed loop system. With the PEM electrolyser off the
system has a lower steady state output due to the cumulative losses in the energy transformation process
and limited supply of hydrogen for operation of the fuel cell.
Results of MATLAB Simulation for Maximum Power of Design for various scenarios during Sunlight Hours
The data from simulation results indicate that the PV and BESS system can charge between 3 and 122 units
while the PV, BESS and H2 system can charge between 4 and 144 units. Graphical representation of the EVSE
Potential based on charge time is shown below.

ECONOMIC ASSESSMENT
The economic assessment is a crucial part of the feasibility study since it determines whether the investigated
resources and technologies are realizable in the system. The financial analysis above together with the formula
for calculation follows international format used in all publications and studies so that an easy comparison can
be made (Walker, Lockhart, Desai, Ardani, Klise, Lavrova, Tansy, Deot, Fox, Pochiraju 2020, 11-13).
