ABSTRACT
The main objective of this project is to implement the sun tracking dual-axis solar
panel in the market which is more efficient compared to the existing solar panels,
and increasing the productivity. The solar panels is one of the most important
source in producing electricity in renewable energy.
It is primarily designed to produce electricity from sunlight. Each individual panel
is constructed of a layer of silicon cells, a metal frame, a glass casing surrounded
by a special film, and wiring. For maximum effect, the panels are grouped
together into array and placed on rooftops or in large outdoor spaces. The solar
cells, which are also referred to as photovoltaic cells, absorb sunlight during
daylight hours.
Within each solar cell is a thin semiconductor wafer made from two layers of
silicon. One layer is positively charged, and the other negatively charged, forming
an electric field. When light energy from the sun strikes a photovoltaic solar cell, it
energizes the cell and causes electrons to ‘come loose’ from atoms within the
semiconductor wafer. Those loose electrons are set into motion by the electric field
surrounding the wafer, and this motion creates an electrical current.
Other advantage is it will give 40% more electricity than a nonmoving solar
4
panel.it has a higher degree of flexibility ,allowing for a higher energy output on
sunny days, higher degree of accuracy in directional pointing.
Force is achieved with the help of dual-axis motion . Now in this world the
electricity generation will be increased. Now we are using the most basic type of
solar panels.
The aim of the project is to design and construct a dual-axis rotating solar panels
that will tilt in the direction of sun automatically. The machine is portable.
Solar power represents 9.8% of the total installed power capacity in India as of Q1
2020. Small hydro installations contributed a lower share than the same time last
year at 1.26%, down from 1.28% last year, Installed capacity, if we implemented
dual-axis panel then the contribution of solar energy.

CHAPTER 1
INTRODUCTION
the energy from the sun can be used to overcome the energy crisis generated by the scarcity of
Fossil fuel resources, Solar energy is free and everywhere. Due to the decreasing of solar
photovoltaic energy cost, it’s superior in the renewable energy sources and widely utilized in
many countries. Solar power is one of the most widely used alternative pathway in the renewable
energy domains or sources. The global demand/installation and production of PV modules are
parallel increasing exponentially for the past 10 years with the largest share/development located
in Europe followed by Asia Pacific region . Solar energy is a very large, inexhaustible source of
energy. The power from the sun intercepted by the earth is approximately (1.8×1011) MW,
which is many thousands of times larger than the present consumption rate on the earth of all
commercial energy sources. Problem associated with the use of solar energy is that its availability
varies widely with time. The variation in availability occurs daily because of the day night cycle
and also seasonally because of the earth’s orbit around the sun. To rectify the problems the
solar panel should be such that it always receives maximum intensity of light. It has been seen
since past that the efficiency of the solar panel is around 10-15% which is not meeting the desired
load requirements. So there is a need of improving the panel efficiency through an
economical way.
1.1 LINKAGE MECHANISM
Solar PV panels are comprised of many small photovoltaic cells – photovoltaic meaning
they can convert sunlight into electricity. These cells are made of semi-conductive
materials, most often silicon, a material that can conduct electricity while maintaining the
electrical imbalance needed to create an electric field.
When sunlight hits the semiconductor in the solar PV cell the energy from the light, in the
form of photons, is absorbed, knocking loose a number of electrons, which then drift freely
in the cell. The solar cell is specifically designed with positively and negatively charged
semiconductors sandwiched together to create an electric field (see the image to the left.
This electric field forces the drifting electrons to flow in a certain direction- towards the
conductive metal plates that line the cell. This flow is known as an energy current, and the
strength of the current determines how much electricity each cell can produce. Once the
10
loose electrons hit metal plates, the current is then directed into wires, allowing the
electrons to flow like they would in any other source of electric generation .
As the solar panel generates an electric current, the energy flows through a series of wires
to an inverter . While solar panels generate direct current (DC) electricity, most electricity
consumers need alternating current (AC) electricity to power their buildings. The inverter’s
function is to turn the electricity from DC to AC, making it accessible for everyday use
11
1.2 USES OF RENEWABLE ENERGY
Renewable energy offers a range of benefits including offering a freely available source of energy
generation. As the sector grows there has also been a surge in job creation to develop and install the
renewable energy solutions of tomorrow.
Renewable sources also offer greater energy access in developing nations and can reduce energy
bills too .Of course, one of the largest benefits of renewable energy is that much of it also counts as
green and clean energy. This has created a growth in renewable energy, with wind and solar being
particularly prevalent.
However, these green benefits are not the sole preserve of renewable energy sources. Nuclear power
is also a zero-carbon energy source, since it generates or emits very low levels of CO2.
Some favour nuclear energy over resources such as solar and wind, since nuclear power is a stable
source that is not reliant on weather conditions. Which brings us onto some of the disadvantages of
renewable energy

1.3 TYPES OF SOLAR PANELS
Monocrystalline and polycrystalline solar panels
Both monocrystalline and polycrystalline solar panels have cells made of silicon wafers. To build a
monocrystalline or polycrystalline panel, wafers are assembled into rows and columns to form a rectangle,
covered with a glass sheet, and framed together.
While both of these types of solar panels have cells made from silicon, monocrystalline and polycrystalline
panels vary in the composition of the silicon itself. Monocrystalline solar cells are cut from a single, pure
crystal of silicon. Alternatively, polycrystalline solar cells are composed of fragments of silicon crystals that
are melted together in a mold before being cut into wafers.
Thin-film solar panels
Unlike monocrystalline and polycrystalline solar panels, thin-film panels are made from a variety of
materials. The most prevalent type of thin-film solar panel is made from cadmium telluride (CdTe). To make
this type of thin-film panel, manufacturers place a layer of CdTe between transparent conducting layers that
help capture sunlight. This type of thin-film technology also has a glass layer on the top for protection.
Thin-film solar panels can also be made from amorphous silicon (a-Si), which is similar to the composition
of monocrystalline and polycrystalline panels. Though these thin-film panels use silicon in their composition,
they are not made up of solid silicon wafers. Rather, they’re composed of non-crystalline silicon placed on
top of glass, plastic, or metal.
Lastly, Copper Indium Gallium Selenide (CIGS) panels are another popular type of thin-film technology.
CIGS panels have all four elements placed between two conductive layers (i.e. glass, plastic, aluminum, or
steel), and electrodes are placed on the front and the back of the material to capture electrical currents.

1.4 ANALYSIS AND SYNTHESIS OF LINKAGE
The primary mathematical tool for the analysis of a linkage is known as the
kinematics equations of the system. This is a sequence of rigid body transformation
along a serial chain within the linkage that locates a floating link relative to the
ground frame.
Each serial chain within the linkage that connects this floating link to ground
provides a set of equations that must be satisfied by the configuration parameters
of the system. The result is a set of non-linear equations that define the
configuration parameters of the system for a set of values for the input parameters.
Freudenstein introduced a method to use these equations for the design of a planar
four-bar linkage to achieve a specified relation between the input parameters and
the configuration of the linkage. Another approach to planar four-bar linkage
design was introduced by L. Burmester, and is called Burmester theory.

1.5 4 BAR LINKAGE
The diagram below shows a four-bar linkage. This mechanism has the following
parts:
Four links that are connected by four rotating joints.
Three of the links can move, but the fourth is fixed in position. This link is
called the ground link.
One of the moving links is a crank that is rotated by a motor.
As the crank rotates, it causes two other links to move while the ground link
remains fixed in position. Varying the lengths of the links produces different
patterns of movement.

roughness, Feed was the dominating factor followed by Depth of cut and speed.
Vikas B. Magdum, et.al used Taguchi method for optimization of cutting forces
andprocess parameters on EN8 steel. For conducting experiments L9 orthogonal
array was selected. For Cutting forces (Feed and Tangential force), Feed and Depth
of cut were the dominating factor followed by speed and Tool material
S.R Das, et.al determine the optimal cutting parameters for low Tool wear and low
Surface temperature. They performed turning operation on AISI D2 steel. The
experiments were conducted using Taguchi’s L9 Orthogonal technique and
analysis of variance was used to identify the effect of cutting parameters.
W.H Yang, et.al used Taguchi method to find the optimum cutting parameters.

Sayak Mukherjee et.al conducted experiments on SAE 1020 steel using taguchi
method to optimize cutting parameters with respect to material removal rate. L25
orthogonal array was used in conducting experiments. The result shows that Depth
of cut had significant effect on Material Removal Rate followed by feed and speed.
16
DeoreDhirajet.al have studied the optimization and evaluation of cutting forces in
turning operation of EN19 steel. In this optimization technique used is taguchi
method and analysis of variance is done to find which parameters have significant
effect.
Hrones and Nelson , in their paper on Analysis of the Four-Bar Linkage gives
review that a 4-bar mechanism is a basic 1-DOF (degree of freedom) mechanism.
A 4-bar is created by selecting four link lengths and joining the links with revolute
joints to form a loop. A wide variety of paths are possible by arbitrarily choosing a
point on the coupler curve. These different curves can be obtained by constructing
a physical model of the mechanism and viewing the path of various points without
detailed mathematical analysis.
B.Malleswara Swami et al. in this paper author describe the method for static and
dynamic analysis. Author used standard bed for analysis. The investigation
is carried to reduce the weight without changing the structural rigidity and the
accuracy byadding the ribs at the suitable location. Static analysis is done for 1g
i.e. gravitational force is consider with external load on structure and 5g i.e.
gravitational force 5 times ‘g’ value is applied on structure along with external
load.
Sayak Mukherjee et.al conducted experiments on SAE 1020 steel using taguchi
method to optimize cutting parameters with respect to material removal rate. L25
orthogonal array was used in conducting experiments. The result shows that Depth
of cut had significant effect on Material Removal Rate followed by feed and speed.
Manjunatha.Ret.al investigated the optimum value of tangential force, feed force,
and surface roughness for EN19 steel using confirmation test. They have used L27
orthogonal array. For Surface Roughness Annova result shows that, Feed is the
most dominant factor. For Cutting forces (Feed and Tangential force) Depth of cut
and Feed is the significant factor.

3.2.1 WELDING
Welding is an operation whereby two or more parts are united by means of heat or
pressure or both. It is used on metals, thermoplastics and sometimes wood.
3.2.2 DRILLING
The action of making a hole in something by boring with a drill.This process is
done using lathe machine.
3.2.3 QUENCHING
In materials science, quenching is the rapid cooling of a workpiece in water, oil or
air to obtain certain material properties. A type of heat treating, quenching prevents
undesired low-temperature processes, such as phase transformations, from
occurring.
3.2.4 GRINDING
A grinding mechanism includes a rotating body, a first grinding wheel, a
second grinding wheel, a first fastening means, a second fastening means, and a
spacer assembly, a first fastening means passing through the first body portion and
22
fastening into the rotating body, a second grinding wheel including a second body
portion and a second grinding portion.
3.2.5 LATHE OPERATIONS
3.2.5.1 TURNING
Turning operations are carried out on a lathe machine which can be manually or
CNC operated.
Turning specific operations include: The general process of turning involves
rotating a part while a single-point cutting tool is moved parallel to the axis of
rotation
3.2.5.2 THREADING
Single-point threading, also colloquially called single-pointing (or just thread
cutting when the context is implicit), is an operation that uses a single-point tool to
produce a thread form on a cylinder or cone. The tool moves linearly while the
precise rotation of the workpiece determines the lead of the thread.
3.2.5.3 KNURLING
The operation is performed for producing indentations on a part of a workpiece.
Knurling allows hands or fingers to get a better grip on the knurled object than
would be provided by the originally smooth metal surface.
23
3.2.5.4 FACING
Facing in machining can be used in two different areas: facing on a milling
machine and facing on a lathe. Facing on the milling machine
involves various milling operations, but primarily face milling. On the lathe, facing
is commonly used in turning and boring operations.
3.2.5.5 MILLING
Milling is performed with a milling cutter in various forms, held in a collett or
similar which, in turn, is held in the spindle of a milling
machine. Mill orientation is the primary classification for milling machines. The
two basic configurationsare vertical and horizontal - referring to the orientation of
the rotating spindle upon which the cutter is mounted.
3.2.5.6 CUTTING
In this project we have performed cutting operation on the girders. First of all the
girders are cut with help of abrasive cutter and dimensions varies for every frame.
3.2.5.7 ARC WELDING
After cutting all girders next operation is welding operation. Arc welding is a
process that is used to join metal to metal by using electricity to create enough heat
to melt metal, and the melted metals when cool result in a binding of the metals. It
is a type of welding that uses a welding power supply to create an electric arc
between an electrode and the base material to melt the metals at the welding point.
We can use
24
either direct (DC) or alternating (AC) current, and consumable or non-consumable
electrodes. The welding region is usually protected by some type of shielding gas,
vapour or slag.
In this we have welded together all the cut pieces of girder with arc welding. This
process leads to the formation of 3 frames i.e. 1) base frame 2) horizontal frame 3)
vertical frame.

4.3 DESIGN CALCULATION
Cutting force is the total force required by the press machine to cut the blank from
the sheet.
Cutting force = L x S x Tmax
L=length of the rod
S=rod thickness
Tmax=shear strength
Tensile strength and shear strength related to following formula:
Tensile strength = 345–525 MPa
Tensile strength = 1.73 * Shear stress
Therefore shear stress = 200-300 MPa
Which means that shear stress for mild steel will be 200–300 MPa.
Tmax=300 N/mm2
L= 30cm = 300mm
S=6mm
Cutting force = LxSxTmax
=300x6x300
=540x10^3 N
