Efficiency data of the
final product
Prior to the photovoltaic performance validation, the MPPT system
was tested for functionality with a
high power supply. The functional
test yielded that our system worked
perfectly under constant current
conditions as well as constant voltage conditions. During the functional test, the input and output
voltage and current were collected
and the efficiency was determined.
The collected experimental data
and calculated efficiencies are presented in Table 2. Moreover, Fig. 9
illustrates the efficiency plot of the
MPPT system as a function of the
output power.
The pump begins to work at approximately 1 A of output current,
pumping water at a minimum rate.
The efficiency observed at this instant is approximately 34.42%,
which seems to be normal since the
output power is low. As can be seen
from Fig. 9, while the efficiency of
72.47% was achieved at 15.62 W,
the maximum power of MPPT was at
21.55 W, as indicated in Table 2.

MPPt operations guide
First, the MPPT, the solar panel, and
the water pump have to be connected, as shown in Fig. 10. The solar
