I. INTRODUCTION
Sunlight based force is an option engineering that will
assuredly lead us far from our petroleum subordinate vitality
sources. The real issue with sunlight based board innovation
is that the efficiencies for sun based force frameworks are
still poor and the expenses for every kilo-watt-hour (kwh)
are definitely not focused, much of the time, to contend with
petroleum vitality sources. Our objective is to plan a
Maximum Power Point Tracker (MPPT), a particular sort of
charge controller that will use the sun oriented board to its
most extreme potential. The MPPT screens the yield voltage
and present from the sun based board and decides the
working point that will convey that greatest measure of
force accessible to the batteries. Utilizing PSO method
MPPT can precisely track the continually changing working
point where the force is busy's greatest, and afterward the
productivity of the sun oriented cell can likewise be
expanded. The expense profit for sunlight based force
frameworks is so low there is no option be broadly utilized
for fueling homes, organizations, or even individual items.
Then again, the profit of using sun powered power in space
far exceeds the expense to execute them. Sun powered force
framework is less expensive than the expense to send
transmission lines from the force matrix. On the other hand,
PV frameworks further improve the rate at which the
electron sent into the conduction band through the procedure
of doping .Solar force is an astounding innovation as in it
changes over daylight into power through the semiconductor
material alone. Over the long haul, more up to date
producing procedures and plans will demonstrate these sun
powered boards more proficient and less excessive in future
years. A sun based board's yield shifts relying upon certain
surrounding climate conditions, for example, temperature,
enlightenment, how clear the sky is, on et cetera. Our
current workload is to plan a gadget that will extricate the
most extreme sum.
II. VOLTAGE-CURRENT (V-I) CHARACTERISTIC
Extracting the maximum amount of power from the solar
panel is difficult due to the nonlinearity of the Voltage-
Current (V-I) characteristic. Figure 1.1 shows the V-I
characteristic for Solar Corp’s 379 Solar.
Fig. 1.1: Characteristic of Solar Corp 379 Panel
The blue line in Figure 1.1 is the actual V-I
characteristic and the pink line corresponds to the power as
a function of the voltage (P = I*V).To get the maximum
power from the solar panel, the solar panel must always be
operated at or very near the point where the power curve is
at a maximum, its peak point. However, this operating
point will constantly change due to the constantly changing
ambient conditions. Irradiance is a characteristic that deals
with the amount of sun energy reaching the ground. The
irradiance reaching the earth significantly depend on where the
panel is located geographically, the angle of the sun, and the
amount of haze or cloud cover preventing all of the suns
energy from reaching the ground. Silicon Semiconductor
solar panel will decrease from 1700 cm2/volt-sec at 27o
C to
440 cm2
/volt-sec at 227o
C.where the hole mobility will
decrease from 600 cm2
/volt-sec at 27o
C to 200 cm2
/volt-sec
at 227o
C[4]. Temperature also causes the band gap energy
of the semiconductor material to increase. Insolation levels
measure the amount of energy in watt-hours for a square
meter over a single day in Kwh/m2
/day. Insolation level units
are not always stated, and can be seen as a ratio.

(IJSRD/Vol. 2/Issue 08/2014/102)
Ten of our 50W solar cells would generate
500W[3]. This would yield a maximum of 20.8A, very
comparable to other controller’s ratings. The table below
shows how big our batteries must be in amp hours, to
provide a 100W light bulb with power.
All unit in amp 100w load 200w load 300w load
1 Day 34 67 100
2 Days 67 134 200
3 Days 100 200 300
4 Days 134 267 400
5 Days 167 334 500

Table 1.3 is calculated using the following formula
Calculating the derivative gives more insight into
the effect of the quantization noise in power. The derivative
is calculated as follows.
The difference in the two power samples is 32
rather than the quantization of 1 from the voltage and
current samples. Calculating the derivative gives more
insight into the effect of the quantization noise in power.
The derivative is calculated as follows.
This means that one bit change in current and voltage
will create a derivative of 32 / e in
register value equals 0.078 watts / duty cycle. This will get
worse as the voltage or current moves up towards their
maximum value.
To test this quantization on our system, a steady duty
cycle is applied to the input of the system while measured the
changing voltage and current samples.
This setup is shown in Fig. 1.4
Fig. 1.4: Test Setup to Measure Quantization and Noise
The resulting voltage and current quantization
noise is shown in Figures 1.5 and 1.6. Note the values are in
10 bit register values

IV. BASIC PSO ALGORITHM
New Velocity
vi(k+1) = vi(k) + γ1i(pi – xi(k)) + γ2i(G – xi(k))
New Position
xi(k + 1) = xi(k) + vi(k + 1)
i – particle index
k – discrete time index
vi – velocity of ith particle
xi – position of ith particle
pi – best position found by ith particle (personal best)
G – best position found by swarm (global best, best of
personal bests)
g(1,2)i – random numbers on the interval [0,1] applied to ith
particle.
A. The Common PSO Algorithm
vi(k+1) = φ(k)vi(k) + α1[γ1i(pi-xi(k))]+α2[γ2i(G – xi(k))]
φ - Inertia function
α1,2– Acceleration constants

V. EXPERIMENTAL EVALUATION
So as to research the precision and execution of the
proposed technique, a photovoltaic (PV) framework
incorporates: one OFFC silicon sun powered board, a
DC/DC converter, a battery and control framework (PSO
MPP tracker and PID controller) are viewed as and recreated
in MATLAB/SIMULINK programming. Which
incorporates the PV module, the buck-help converter
(Rashid, 2004) and the MPPT calculation The buck –
support dc/dc converter is used because of a few reasons, in
particular it displays better attributes with deference than the
execution of PV cluster's MPP and it takes after the MPP at
all times, paying little heed to the sunlight based insolation,
the show temperature, and the associated burden. The PV
module current and voltage are encouraged to the converter
and the MPPT controller all the whi.

The framework was broadly tried in lab with numerous
distinctive variables. The framework ought to work in all
conditions; however testing ought to be run for a full day's
length, confirming the essential parts of it is fundamental.
A mixture of distinctive applications were explored
and figured out if or not they are even plausible at the
current state of sunlight based innovation. Framework
moves in like manner with diverse daylight intensities and

VI. CONCLUSION
To finish this undertaking in a compelling way an
exhaustive understanding of sun powered innovation
and The most doable application for sun oriented force
is for remote areas obliging little amounts of force to
run lighting, pumps, and other low power applications.
Just uniting a sun powered board to a battery or a heap
can further decline the accessible productivity. Sunlight
based force frameworks profit from a MPPT gadget
keeping in mind the end goal to concentrate the greatest
accessible force from the sun powered boards in the
framework. By observing the voltage and current yield
of the sun oriented board, the MPPT tracks the
continually changing working indicate in place draw the
most extreme measure of force accessible amid all
times of the day. To meet this principle outline
necessity, numerous segments and working conditions
were chosen focused around a proficiency examination
that was performed keeping in mind the end goal to
minimize the force misfortune through the hardware. A
careful force misfortune examination turned out to be
more prominent than 96% effective. A circuit that
would screen the sun based board's energy yield and
alter the working conditions focused around a control
framework so as to expand the force yield was
effectively outlined. An exceptional flow sensing
thought was executed that minimized the force
misfortune contrasted with different plans inquired
about.
