PERANCANGAN SOLAR TRACKER SEBAGAI PENINGKATAN EFISIENSI ENERGI LISTRIK YANG DIHASILKAN PANEL SURYA DENGAN MENGGUNAKAN LOGIKA KABUR (FUZZY LOGIC)
Abstract: At this
time greatly increased
energy needs. Among
them is a
need for electricity increases.
Various aways used
to increase the
supply of electrical energy world, solar panel is an
alternative options, but
solar panels are commonly
used manual way,
that is by
exposing the solar
panel on a trajectory that is often passed by the sun
is orientate in one direction.Thus,
in this research
tries to make
a solar tracker
using LDR (Light Dependent Resistor),
and a control
system using fuzzy
logic (Fuzzy Logic). The
working principle of
solar tracker when
the sun is
shining on the
LDR LDR resistance decreases
so that the
current flowing through
the LDR increases. When
dark LDR resistance
increases and the
current flowing through the
LDR decreases. This
phenomenon is diamanfaatkan
as a light sensor. The difference of the current
value of the four sensors are used as an analog
input on the
microcontroller ATMega 16
which was then
converted into a digital signal
and converted back to an analog
signal as the output of the microcontroller. The analog signal
from a microcontroller such as 5 volts which then flows into
the leg base transistor that
acts as a trigger relay that serves as a bridge for motor control actuators
H as a driver of solar panels. Thus
the light received
by the solar
panels can be
more optimal than
if the solar panels are only
facing at one point coordinates. From
the research shows
that increases power
output of solar
tracker than the electrical power
generated by the solar panels without fuzzy logic control by 12.10%
at 10 ohm
load and 2.56%
at 100 ohm
load. Using fuzzy
logic control efficiencies increased
1.39% in the
10 ohm load
and 0.06% at 100
ohm load compared to solar panels without fuzzy logic control.
