result. The same goes at 6 pm on day 1; the solar tracker can produce more power
which is at 1.14 W compared to the fixed solar panel which only produces 0.58 W.
From this result, the solar tracker can perform better in the morning and evening
because the solar tracker’s surface can face the sun directly while the fixed solar
panel cannot do that. At 12 pm in day, both solar panels produce the same result and
nearly achieve 100% of their capability performance. Both solar trackers produce
97.14% from their maximum capability of 14 V. For the current output, both solar
panels produce 86.66% from their maximum capability 1.5 A and 88.4% from 20 W
power.
The lowest output produced by both solar trackers is at 6 pm where it is almost
sunset. The percentage of the produced solar tracker voltage from the maximum
capability is 27.21% while the fixed solar panel is 20.7%. The difference in percentage
is 6.51%. At 6 pm, solar tracker only produces 0.3A which is only 20% from the
maximum capability while the fixed solar panel produces 0.2A which is only 13.33%
from maximum capability. The difference that the solar tracker can produce is 6.67%
more compare to fix solar panel.
For the total average in day 1 from 8 am to 6 pm, the voltage produced by the
solar tracker which is 10.7 V reached 76.42% from the maximum capability while
the fixed solar panel is 9.39 V, only reached 67.07% of its maximum capability with
the different of 9.35% that was produced by solar tracker. The total average current
produced by the solar tracker reached 58% from the maximum it can produce while
the fixed solar panel produced only 53.33%. So the different current output from
both solar panels is 4.67% which is led by the solar tracker.
For the average percentage of power output produced by the solar tracker is 48.8%
while the fixed solar panel is 44.35%. So the solar tracker can produce extra 4.45%
power output compared to the fixed solar panel in day 1 from 8 am to 6 pm.
14.5 Conclusion
Solar irradiation is one of the alternatives to get free energy. From this research, it
is proven that using a solar tracker will increase the output of the solar panel. The
more efficient the solar tracker, the better its performance to increase the output
of the solar panel until it reaches the maximum output from morning to evening.
The method which utilizes two servo motors will generate more electric power as
the solar tracker is more likely to move according to the position of the sun. Solar
irradiation is known as a free source that can be utilised in from tropical countries
such as Malaysia. Instead of using many solar panels, the solar tracker is one of the
good alternatives to improve and increase the efficiency and output of the solar panel.
Solar irradiation is free source but it is a bit costly. Furthermore, the maintenance of
solar tracker is free.
