 ABSTRACT

Now-a-days, dealers of natural resources like fuel, coal etc. are facing a hard time to
keep pace with the increasing demand. Therefore, to carry out this demand it is quite
necessary to make a new exploration of natural resource of energy and power. Therefore
sunlight is now-a-days considered to be a source of energy which is implemented in various
day to day applications. Solar energy is being used to produce electricity through sunlight.
With the help of this technology we aim to make solar energy powered car in our project.
The main component to build a solar car is the solar panel. The solar cells collect a portion of
the sun's energy and store it into the batteries of the solar car. Before that happens, power
trackers converts the energy collected from the solar array to the proper system voltage, so that
the batteries and the motor can use it. After the energy is stored in the batteries, it is
available for use by the motor & motor controller to drive the car. We are going to use two
set of batteries; one of which will get the electrical energy from the panel to drive the motor
and another will be used as a back-up source of energy which will provide required power
when there is no sunlight. The motor uses that energy to drive the wheels. Preliminarily our
objective would be to implement our idea on a remote control toy car and afterwards with help
of this prototype we can extend our future work on building a actual car powered by the solar
energy.

 CHAPTER –1 INTRODUCTION

Our global temperatures rise is caused by our atmosphere’s ever-increasing

content of carbon-dioxide, most of which comes from the exhaust of transportation
vehicles. This has resulted in a worldwide search for alternatives to the high-powered
gasoline fuelled automobiles in wide use today conference. With the current rate of
inflation in India and the ever-increasing fuel prices all around the world, the clean
solar car will be beneficial to both the environment and the public who are otherwise
exposed to many health problems due to toxic exhaust gases from fuel power cars.
Also due to rising fuel prices, fuel run cars are becoming less popular among the
general people as maintaining such a car is proving to be beyond their affordability
standard. Price of different fuels has increased over a decade with the price of diesel
increasing the most. The price of the fuels is also affected by annual inflation in India
which stands at 6% on an average.

This raises the already increasing fuel price by a factor of 0.06 hence making
the conventional cars even expensive. The solar car is expected to reduce air
pollution, improve public health and reduce dependency on fossil fuels. Considering
the probable positive effects of different factors on the price associated with owning
and using a solar car as a commuter, it can certainly be stated that in the upcoming
years, with a fall in solar panel’s price and externalities costs and an expected aid
from the government, solar cars will evolve as the most economically viable vehicle
of the decade.
There must be some limits to the ability of the earth to sustain a growing
population. Fortunately, population models suggest that the world's population will
probably level out at about two to three times the present numbers over the next
hundred years. The question is whether the earth's resources are sufficient to sustain
that population at a high standard of living for all. In this the key issue is energy.

Now-a-days, dealers of natural resources like fuel, coal etc. are facing a hard
time to keep pace with the increasing demand. At one hand, there are more cars or
motor vehicles are dominating the transport medium, on the other hand these cars are
being dominated by the fuel. As a result, the limited resources are being quashed by
the producers and dealers to satisfy this need which is leading us to an uncertain
future with having the scarcity of fuel and minerals. So, it is clear that present trends
in energy consumption, especially oil, cannot be sustained much longer. Again, in
view of the possibility of global warming, these resources are playing a negative role.

Therefore, under these circumstances, it is quite necessary to make a new

exploration of natural resource of energy and power. But why exploration when the
resource is in front of our bear eye. It is effective, less expensive and above all, it is
an endless source of energy. With greatly improved energy efficiency, a transition to
this energy based economy capable of sustaining the anticipated growth in the world
economy is possible. This effective source is "Solar Energy".

[1]
1.1 Why We Need Solar Car?

Due to global warming the demand and request for green energy produced by the
renewable sources like solar power is increased. The end user will prefer the solar energy as
a solution rather than a fix ground system because of such given reasons.
 In the present scenario fossil fuel and Bio fuels will become too costly and it is out of
reach for a common man, for far thinking in future we will end up exhausting fossil fuel.
 So best option is sun and it is the prime and ample source of energy in the world.
 Science has proved it is unlimited source and direct source of energy since birth of earth.
 Further solar car will be pollution free & environment friendly,
 It's the best alternative of car rather than run by diesel and petrol, etc., and which is one
of the most disastrous causes of environmental (air) pollution, the modern generation is
facing today.
 Solar Car would definitely be much cheaper in comparison of diesel /petrol cars. We can
utilize money [which we spend for buying petrol/ diesel) in other economic growth of our
nation/ whole world.]

1.2 What Is Solar Car?

 A solar vehicle is an electric vehicle powered completely or significantly by direct solar

energy. Usually, photovoltaic (PV) cells contained in solar panels convert the sun's
energy directly into electric energy.
 The term "solar vehicle" usually implies that solar energy is used to power all or part of
a vehicle's propulsion.
 Solar vehicles are not sold as practical day-to-day transportation devices at present, but
are primarily demonstration vehicles and engineering exercises, often sponsored by
government agencies.

[2]
1.3 Advantages & Disadvantages:
 Advantages :
 Solar power is pollution free during use. Production end wastes and emissions are
manageable using existing pollution controls. End-of-use recycling technologies are
under development.

 Facilities can operate with little maintenance after initial setup.

 Solar electric generation is economically superior where grid connection or fuel

transport is difficult, costly or impossible.

 When grid-connected, solar electric generation can displace the highest cost electricity
during times of peak demand can reduce grid loading.

 Grid-connected solar electricity can be used locally thus reducing

transmission/distribution losses.

 Once the initial capital cost of building a solar power plant has been spent, operating
costs are extremely low compared to existing power technologies.

 The power obtained by solar tracking is almost constant over a period of time when
compared with the output obtained by a panel without tracking.

 Disadvantages:
 Solar electricity is almost more expensive than electricity generated by other sources.

 Solar electricity is not available at night and is less available in cloudy weather
conditions. Therefore, a storage or complimentary power system is required.

 Limited power density.

 Solar cells produce DC which must be converted to AC when used in currently existing
distribution grids

1.4 Problem Statement

Solar energy is an energy obtained by converting the solar radiation into

electricity. The ability of solar energy is limited and only capable to generate
electricity only during the day. This energy is also not stable and a lot of factors that
need to be considered for the use of solar energy. Solar photovoltaic (PV) is a way to
collect solar energy generated through solar radiation. But arising of solar power
capacity is unknown and the percentage decrement of this energy potential is hidden.
One way to evaluate the ability of solar energy is to use solar energy into physical
form. A mini solar car will be designed to evaluate the ability of solar energy
collected by solar panels. Electricity generated is measured by taking the speed of a
car moving in particular distance. If there is a difference of speed was recorded even
in the same condition, it is clear there are factors that affect the speed. This
difference may have occurred in cars that are designed or because the collection of
solar radiation.

1.5 Objectives

The objectives of this project are as follows:

1. To evaluate the performance of three different solar cells in terms of power.

2. To design and fabricate an actual mini race car.

1.6 Scope of Studies

There are two main elements considered in this project which are:
1. Evaluate the performance of solar energy through the car speed.

2. Perform analysis on each component of the solar car at a maximum level.

 CHAPTER –2 LITERATURE REVIEW

2.1 Emerging trend and Development in Solar car in last

decades
In July 1990, thirty-two North American university teams gathered in Orland,
Florida to compete in GM Sunrace USA, a 1644 mile transcontinental race of solar
powered cars. Using only sunlight for power. Michigan. Created as a student
competition to strengthen hands-on science and engineering skills. [2]

The prize for the three winners of Sunrayce was an all expense paid trip to
compete in the 1990 Australian World Solar Challenge (WSC). The WSC is a 1870
mile solar car race across the Australian continent that stretched from Darwin to
Adelaide. This year's event had thirty-six competitors from around the world,
including eleven entries from Japan, eight from the U.S., and five from Europe. In
total, sixty-two different solar racing teams competed in these two events in 1990.
[2]

In November 1990, a Sebring kit car on a Volkswagen Beetle chassis was

purchased for conversion to a solar electric commuter car. The car as purchased
weighed 1600 lbs. with the engine. The body was removed from the chassis and
unnecessary components, engine, fuel tank, pop-up headlights, etc., were removed.
The back of the body was modified to accept a 45" x 44" solar array frame. When
solar energy cannot be used to charge the car's batteries a plug-in charger is used. The
vehicle had to meet Pennsylvania State inspection requirements for a standard
passenger car with electric motor drive. Also, the car should have a commuting range
(derived from solar energy) of 30 miles and be able to reach highway speeds (55
mph). [1]

Solar cars started their existence through universities and manufacturers.

Starting with MIT in USA, universities from 24 other countries across the world has
currently devoted research and manufacturing groups in solar cars . Manufacturers
from the US (Sun Motor), India (Reva), Taiwan and France (Venturi) are expecting
to bring their solar commuter cars for general public. With high performance and low
cost solar cells being produced, more sophisticated and developed solar vehicles are
coming into existence.[4]

[5]
2.2. Preliminary Design and Economic Analysis
2.2.1 System Architecture
The detailed system architecture of the complete electric drive system of the
solar car is shown in a block diagram .The solar panels mounted on the roof of the car
will collect energy from the sun and convert it to usable electrical energy which will
be stored in a lead acid battery through a charge controller. The charge controller will
ensure healthy life of the battery by preventing over charging and over discharging of
the battery. The solar car will also have a provision of plug-in charge when there is
not enough sunshine due to cloud, fog or rain. This provision for external plug in to
charge the batteries from the conventional power supply will also allow the car to
increase its capacity to drive for longer distance by putting additional batteries and
charging from the power supply lines. The voltage controller will maintain a constant
voltage at its output as is required by the motor, irrespective of the panel or the
battery voltage level. [4]

Figure.1: Block diagram of solar car system [03]

2.2.2 Estimation of Motor Power:

The power needed to drive the car can be calculated using

P=F*V

Where v is the velocity of the car and F is the force needed to overcome the
frictional force between the road and the tires which can be calculated as,

F = m × g × C rr

Where, m is the mass of the car, g is the gravitational acceleration and Crr is
the coefficient of rolling resistance of the car tires. Different tires have different
depending on the type of tires, load, road type, pressure etc. Tires used for solar car
are typical bicycle tires and have rolling resistance of 0.0055 on asphalt/concrete
roads. Assuming a maximum car speed v = 60km/h, mass m = 500 kg (with the car
weight about 300 kg, weight of four 40 Ah batteries 50 kg, and weight of two

[6]
passengers 150 kg) and g = 9.81 m/s2, the maximum power required to drive the car
is found to be about 450 .[4]

2.2.3 Battery Capacity

The four most popular choices for battery chemistry are lithium ion (Li-Ion),
lithium polymer (Li-Po), nickel metal hydride (Ni-MH), and lead acid (Pb-Acid).The
most successful vehicles tend to use Li-Ion cells due to their superior energy
density.[5]

Battery capacity depends on the energy battery has to supply which in turn
depends on the total distance travelled. As the solar car is contemplated to be used
mainly by the office-goers in Dhaka, one of longest distances to travel from one end
of Dhaka to the opposite can be represented by the distance between Matijheel and
Uttara area which is approximately 17.5 km. However, the actual travelling distance
may be even longer than this if the commuter’s residence is located far from the main
road. Therefore, considering this extra distance, a one-way travelling distance of 20
km is assumed, which results in a total distance d = 2×20 = 40 km for a return trip.
Then the total energy that should be supplied by the motor is given by,

Em = P × t

Where (t) = Travel distance / Car speed (v) = 40 min., is the total travel time.
However, it is obvious that the motor will not run at its full power for all the time, as
the power requirement will vary depending on the speed of the motor and road
condition. While the smaller lanes in the residential areas are in poor condition, the
highways are in quite good condition for most of the part. Therefore, for most of the
time, the motor will be running at the minimum calculated power of 450 W. To have
an estimate of the total energy required by the motor to cover the total distance, a
conservative estimate would be to assume that the motor runs at the minimum
calculated power of Pmin=450 W for 80% of time, at the maximum power of
Pmax=700 W for 10% of the time, and at the average value of these two Pav=575 W
for the rest 10% of the time. [4]

2.2.4 Panel Size:

The panel size can now be determined on the basis of the total energy the
battery should supply plus the losses in the battery and the charge controller. If ηch is
the battery charging efficiency and ηCC charge controller efficiency, then the total
energy Ep required from the solar panels is given by,
𝐶∗𝑉𝑏
Ep=η cc∗η ch

Where, C is the total charge to be supplied by the battery plus the charges lost
during discharging according to plus. [4]

2.2.5 Maximum Power Point tracking

At present, the transformation efficiency of the photovoltaic cell plate is very
low, can reach only 14%, the efficiency should be improved according to its output
characteristics. Because of the strong manoeuvrability of the electric car, the working
[7]
environment of the vehicle photovoltaic cell plate changes frequently, so the
algorithm of maximum power point tracking should be correspondingly improved, in
order that the photovoltaic cell plate is always in a high transformation efficiency
condition. The function of the maximum power tracker is to change the equivalent
load take by the photovoltaic cell array, and adjust the working point of the
photovoltaic cell array, in order that the photovoltaic cell array can work on the
maximum power point when the temperature and radiant intensity are both changing.
[2]

Solar Panel works as both Current source & Voltage source. But In the area of
constant current source, the sensitivity of the output current to the working voltage is
very low; while in the area of the constant voltage source, the sensitivity is obvious.
By way of tracking the output voltage of the maximum power of the photovoltaic cell
more and more quickly and accurately, the tracking method should be improved. [2]

2.2.6 Economics Analysis

An economic feasibility analysis of using the solar car over that of a
conventional fuel based car is also made. Details the economic analysis of the solar
car, and puts forward the economic comparison of running a solar car vs. a fuel-based
car, using the present worth of different components of the car over a period of 20
years; and finally makes concluding remarks.

Figure.2 Fuel Prices and Trends [4]

A Life Cycle Cost Analysis of Solar Car the LCC of the solar car involves the
price trend of the solar panel itself, the life span, installation and replacement and
finally the costs associated with the operation and the maintenance of the panel and
the battery. Over the years it has been statistically observed that the price of the solar
panels is decreasing with increasing demand thus promising cheaper but more
efficient panels in the future. Nevertheless, the initial cost of setting up a panel is
quite high But this initial investment can be compensated by its long life span. Solar
panels are expected to run for at least 20 to 25 years without requiring any major
replacements. [4]

3.1.1 Solar Panel

A solar panel is a set of solar photovoltaic (PV) modules electrically

connected and mounted on a supporting structure. A PV module is a packaged,
connected assembly of solar cells. Solar panels can be used as a component of a
larger photovoltaic system to generate and supply electricity in commercial and
residential applications. Each module is rated by its DC output power under standard
test conditions (STC), and typically ranges from 100 to 320 watts. The efficiency of a
module determines the area of a module given the same rated output - an 8% efficient
230 watt module will have twice the area of a 16% efficient 230 watt module. There
are a few solar panels available that are exceeding 19% efficiency. A single solar
module can produce only a limited amount of power; most installations contain
multiple modules. A photovoltaic system typically includes a panel or an array of
solar modules, an inverter, and sometimes a battery and/or solar tracker and
interconnection wiring.

Types of Solar Panels:

Mono Crystalline:

Monocrystalline solar panels are made from a large crystal of silicon. These
types of solar panels are the most efficient as in absorbing sunlight and converting it
into electricity however they are the most expensive. They do somewhat better in
lower light conditions then the other types of solar panels.

Figure-3.1: Monocrystalline Solar Panel

Polycrystalline:

Polycrystalline solar panels are the most common type of solar panels on the market
today. They look a lot like shattered glass. They are slightly less efficient then the
monocrystalline solar panels and less expensive to produce. Instead of one large crystal, this
type of solar panel consists of multiple amounts of smaller silicon crystal.

[11]
 Figure-3.2 Polycrystalline Solar Panel

Cast Polysilicon:

In this process, molten silicon is cast in a large block which, when cooled, can be cut
into thin wafers to be used in photovoltaic cells. These cells are then assembled in a panel.
Conducting metal strips are then laid over the cells, connecting them to each other and
forming a continuous electrical current throughout the panel.

String Ribbon Silicon:

String ribbon uses a variation of the polycrystalline production process, using the
same molten silicon but slowly drawing a thin strip of crystalline silicon out of the molten
form. These strips of photovoltaic material are then assembled in a panel with the same metal
conductor strips attaching each strip to the electrical current.

Amorphous Solar Panels

Figure-3.3 Amorphous Solar Panel

Amorphous solar panels consist of a thin-like film made from molten silicon that is
spread directly across large plates of stainless steel or similar material. These types of solar
panels have lower efficiency then the other two types of solar panels, and the cheapest to
produce. One advantage of amorphous solar panels over the other two is that they are shadow
protected. That means that the solar continues to charge while part of the solar panel cells is
in a shadow. These work great on boats and other types of transportation.

3.1.2 Battery
The lead–acid battery was invented in 1859 by French physicist Gaston
Planate and is the oldest type of rechargeable battery. Despite having a very low
energy-to-weight ratio and a low energy-to-volume ratio, its ability to supply high
surge currents means that the cells have a relatively large power-to-weight ratio.
These features, along with their low cost, make it attractive for use in motor vehicles
to provide the high current required by automobile starter motors.
As they are inexpensive compared to newer technologies, lead-acid batteries
are widely used even when surge current is not important and other designs could
provide higher energy densities. Large-format lead-acid designs are widely used for
storage in backup power supplies in cell phone towers, high-availability settings like
hospitals, and stand-alone power systems. For these roles, modified versions of the
standard cell may be used to improve storage times and reduce maintenance
requirements. Gel-cells and absorbed glass-mat batteries are common in these roles,
collectively known as VRLA (valve-regulated lead-acid) batteries.

3.1.3 Stepper motor

A stepper motor (or step motor) is a brushless DC electric motor that divides a
full rotation into a number of equal steps. The motor's position can then be
commanded to move and hold at one of these steps without any feedback sensor (an
open-loop controller), as long as the motor is carefully sized to the application.

A step motor can be viewed as a synchronous AC motor with the number of

poles (on both rotor and stator) increased, taking care that they have no common
denominator. Additionally, soft magnetic material with many teeth on the rotor and
stator cheaply multiplies the number of poles (reluctance motor). Modern steppers are
of hybrid design, having both permanent magnets and soft iron cores.

Battery

Figure 6.1 Design of demo car

In our project we are attempting to build a solar car that converts the sunlight
into electrical energy. The main component to build a solar car is the solar panel. The
solar cells collect a portion of the sun's energy so that power trackers can convert the
energy collected from the solar array to the proper system voltage. After the energy is
collected in the panel, it is available for use by the motor &motor controller (which
was connected to the panel). After all these being proceeded, the motor controller
adjusts the amount of energy that flows to the motor to correspond to the throttle.
The motor uses that energy to drive the wheels.

[21]
6.2 How Electricity Arising From Solar Energy

The process of producing solar energy is a process of converting light

(photons) into electrical propulsion known as the photovoltaic effect (PV). Contained
within photon of light contains the number or rate of energy varies depending on the
wavelength and spectrum of solar generated. When the photon is in violation or in
contact with the solar panel, solar panels will absorb photons in some degree.
Not all photons are absorbed by the solar panels because it depends on the
type of semiconductor materials used to produce the solar panels. Photon energy at
certain levels is able to dissolve the bonding electrons from atoms to produce
electricity. Quantity of the energy produce is difference between a material with
other material in the production of solar cells. This energy level is known as band-
gap energy which is measured in units of electron-volts (Andreev V.).
Different materials with band-gap energy values are different. A material with
band-gap energy between 1eV and 1.8 eV is the best material and has a high
efficiency of energy production. Photons with less energy than the band gap energy
pass through the material.

[22]
6.3 Solar Panel Installation
Solar Panels are typically installed on rooftops, building tops, or stand-alone
facilities. It is important to install solar panel so that it gets the most direct sun
exposure. These determine solar panel is maximally effective during the testing
conducted. To implement, there are several resources in helping properly to set up
and installing solar panels by tracking the position of the sun in the sky.

6.4 Solar panel mounting

Solar panel mounts are used to attach PV onto any surfaces. Solar panel
mounts come in three main varieties: pole mounts, roof ground mounts, and flush
mounts. By using these mounts, it can be installed onto a vehicle, on roof, on top of
or against the side of a pole, or even install them as a free standing unit .

6.5 Notice obstructions to sunlight

Remove all unnecessary items that may be blocking sunlight to solar panel
units. Trace the path of the sun in the sky to determine if an object is casting a
shadow over solar photovoltaic panels. If this is the case, then the operating
efficiency of unit will be reducing.

6.6 Position solar panel in direct sunlight

Solar panels perform at optimum capacity when placed in direct sunlight. The
energy collection from the sun are mostly linearly proportional to the site latitude. By
tracking the radiation axis, PV is directly placed under the noontime sun (Zhimin Li )

6.7 Power Produced by Solar Panels

The efficiency of solar panels and the resultant energy produced is dependent
on climatic, geographic, and weather factors. Arid climates are ideal for solar panels
and solar panel will produce more energy in areas where they are exposed to direct
sunlight under clear skies. Even at optimal efficiency, solar panel sonly convert a
small percentage of the energy that strikes it into usable energy.
Years of overheating and physical been using will reduce the operation
efficiency of the photovoltaic unit. Solar cells become less efficient over time and
excess energy is released into its thermally conductive substrate as infrared heat . The
amount of power solar panels produce is influenced by the quality of the solar panel
types, the materials and technology used in making the solar panel and the amount of
time the solar panel been use.

[23]
6.8 Solar Efficiency
Solar efficiency refers to the amount of ambient light can be converted into
electrical energy can be used. Solar cell efficiency is the amount of light the
individual solar cell converts to electricity. Solar cells are placed next to each other
on the back sheet and covered by glass to make solar panels.
The efficiency of solar panels refers to the amount of light that converts the
entire of solar cell surface. The efficiency of a solar panel is lower than that of a solar
cell due to the spacing between cells and because the glass covering reflects away
some of the sunlight.
Solar energy system is often described in terms of total power they can
produce, measured in watts or kilowatts. However, more important factors to
consider when comparing a solar energy system are the amount of the actual
electricity generating system during its lifetime. By using high efficiency of solar
panel.

6.9 Power Produced by Solar Panels

The efficiency of solar panels and the resultant energy produced is dependent
on climatic, geographic, and weather factors. Arid climates are ideal for solar panels
and solar panel will produce more energy in areas where they are exposed to direct
sunlight under clear skies (Ayu W.A. 2008). Even at optimal efficiency, solar panel
sonly convert a small percentage of the energy that strikes it into usable energy.
Years of overheating and physical been using will reduce the operation
efficiency of the photovoltaic unit. Solar cells become less efficient over time and
excess energy is released into its thermally conductive substrate as infrared heat . The
amount of power solar panels produce is influenced by the quality of the solar panel
types, the materials and technology used in making the solar panel and the amount of
time the solar panel been use.

 9. Conclusion
Solar technology is an alternative that can be commercialized in order to replace
non-renewable fuel sources. Based on solar technology, many application have been
produced like, solar car, solar heater and solar street light and many more. In order to
develop the solar technology, many factors must be considered like weather, the
environment factor, reliability of solar module, and also the load. So, this solar
technology still needs improvement in order to achieve higher performance.
It is clear that this project was able to get acquainted with this new area of
photovoltaic solar energy applications. Unfortunately, it was not possible to build a
sample Solar Electric Vehicle because of the low budget and lack of mechanical
engineering expertise. Equipment's purchased for this project were also used in the
solar car project and were very useful in building and testing in the solar car. In
addition, if the power station generating the electricity to recharge batteries uses solar
energy, air pollution is also reduced.

Major limitations of existing products:-

Major Difficulties in Solar Tracking System is that Higher Cost due other devices used in tracking
like Motors, Controllers. Another problem is the inaccuracy of tracking due to cloudy atmosphere and many
other natural conditions. It also requires the higher energy input. It is therefore required to provide a solar

Specific problem solved by the Inventor:-

Inventor had used high quality sensors to increase the accuracy of the tracking the Sun’s trajectory
path. Also Inventor has proposed Three Different method of tracking the sun to minimize the Cost, Input
power, Accuracy and Counter – Balancing.

Brief about the Invention:-

As shown in FIG. 1, brackets 27 and 29 are rigidly attached to a rotatable shaft 16 by collars 28
and 30 respectively. A support 1, which serves as a mounting platform for supporting a solar collector such
as a receiver or reflector or a combination of both and of any geometrical shape is pivoted to bracket 27 by a
pivot 17 perpendicular to shaft 16. Similarly, a support 3 is pivoted at 18 to bracket 29. It is possible to
change the spatial orientation of collector supports 1 and 3 by inclining those using pivots 17 and 18
respectively, which may be desirable for concentrating the sun's rays due to yearly (seasonal) motion of the
earth. Adjustable stays 23 and 22 hold the corresponding supports 1 and 3 at the required inclination
respectively. Shaft 16 is held parallel to the north-south axis of the earth. This is possible by aligning a
horizontal base plate 12, along the north-south direction. This base plate is horizontally held using four
levelling screws, two of which are shown as 13 and 9 in this figure. The other two screws are behind these
screws in this view. Shaft 16 subtends an angle equal to the latitude of the location where this system is
used. Shaft 16 is supported by a roller bearing 15 and a tapered roller bearing 5 on its ends. A
counterbalancing arm 2, which can slide along and rotate around along shaft 16, is adjustably fixed thereto;

[39]
arm 2, which is normal to shaft 16, carries a counter-balancing mass M at an adjustable radial distance P2
from shaft 16.

Fig. 1..1 Construction of solar tracking system.

Mass M on the counter-balancing arm 2 can be moved in the radial direction relative to the shaft 16. The
center of gravity of the support 1 is at a radial distance P1 from the shaft 16. As shaft 16 is rotated, the
moments of the masses of the solar collectors and of their securing assemblies, namely elements 1, 23, 27
and 28 and 3, 22, 29 and 30 are counter-balanced by mass M. If either or both supports 1 and 3 are rotated
about pivots 17 and 18, then their radial distance from shaft 16 will change and one would have to change
the radial distance of mass M from the shaft. A vertical column 11 provides support to shaft 16 in order to
keep it straight. This column has a bushing 11a at its top through which the shaft passes for rotation and
support. Bearings 15 and 5 are held on vertical columns 14 and 6 respectively columns 6, 11 and 14 are
fixed to base plate 12. The solar collector carried by support 3 may consist of an array of solar cells. A
pointer 4 is mounted normal to the array of solar cells carried by support 3. Pointer 4 is used to align the
apparatus such that the receiver on support 1 or solar cells on support 3 are normal to the sun's rays. The
length of the shadow of the pointer indicates the degree of misalignment. In the case of perfect alignment,
there will not be any shadow. Pointer 4 could be mounted on support 1.
There are several methods to do the tracking. It will depend upon the situation where one method
might prove better than the other.
The first and the simplest method is manually rotating shaft 16 by a certain number of degrees in a
time interval based on the rotation rate of the earth, as discussed above. This can also be done merely by
inspecting the shadow produced by pointer 4 i.e. the rotation of the shaft can be done in such a manner that
there is no shadow of pointer 4. Since the earth rotates at a very slow rate, this method can be quite useful in
many countries of the world where many people may not want to spend money on gear boxes, stepper
motors etc. In such cases, shaft 16 has to be supported on bearings 15, and 5 (FIG. 1), and one needs a solar
collector on one support 1 and the counter-balancing system 2, 2a and M. If one uses column 11, the system
will perform better otherwise, the spacing between columns 14 and 6 can be made smaller, and one can
eliminate column 11.
In the second method, which also does not require electrical parts, one can use a gear box where
one can have a worm and worm gear system 8 as shown in FIG. 3. Worm rotation can be produced by using
a knob 19. The torque required to turn knob 19 for a single start worm and an n tooth--gear will be, 1/n
times that required to rotate the shaft having no gear system.

[40]
 In the third method, where one uses a stepper motor along with gear box for optimal torque
reduction, the system required can be seen in FIGS. 1.In this case, one can have two limit switches. One for
the starting position in the morning and the second one for the stopping position in the evening. One also
needs a re-start switch. Here, one can rotate the shaft at a faster rate (most motors have controllers with
features having variable pulse rates) in the morning to align pointer parallel to the sun's rays. In this
situation, the current output of the solar cells will be a maximum as measured by a current meter (not
shown). One can have wiring such that the current meter can be inside the house such that the alignment of
pointer 4 can be easily checked from within the house. It is desirable to be able to align pointer 4 from
inside the house in places having extreme weather conditions. If solar cells and a current meter are provided,
the latter can be used to align the supports without the need of pointer 4. After aligning supports 1 and 3,
one can set the stepper motor to turn at the tracking speed (earth's rotational speed but in a direction
opposite to that of earth) until the evening when the second limit switch is activated to stop the motor
rotation. The motor can then be rotated in the reverse direction at a faster rate, until it activates the first limit
switch for stopping. In this way, the cycle can be repeated.

Key Learning Points:-

- Counter – balancing the Tracking System

- Three Methods of Tracking the Sun’s Trajectory

1. Manually
2. By using Stepper Motor along with Gear box
3. By using Gear box

Summary of Invention:-
The solar tracking system maintains a solar collector with its responsive surface normal to the
sun rays. It includes a shaft supported for rotation about an axis parallel to the north-south axis of the earth.
Tracking can be done in three different ways Manually, By using Gear box and by a stepper motor for
intermittent rotation of the shaft at a mean rate equal to the earth's rate of rotation. This system counter-
balances the assembly and a solar collector fixed there to irrespective of the rotational position of the
assembly about the shaft and the inclination of the support relative to the shaft.

In view of the steadily decreasing worldwide supply of oil resources, alternate source of energy have been
investigated for possible use in powering vehicles, such as automobiles, trucks, buses, etc. Alternate sources
of energy also have been investigated as a means for reducing pollutant levels in large cities, a major portion
of which is emitted from the use of oil derived fuels, such as gas, diesel, etc., in today's vehicles.

[42]
Summary of Invention:-

There is disclosed herein a unique solar powered vehicle utilizing electrical power converted from incident
solar radiation. The solar radiation is converted by a solar panel to electrical energy which is used to charge
storage batteries which, in turn, provide electricity for energizing the electric motor of the vehicle. The solar
panel comprises a lower panel adapted to be mounted on an exterior surface of the vehicle. The lower panel
is formed with a pluarlity of interconnected photovoltaic cells. A pair of first and second upper panels, each
also formed of photovoltaic cells, are pivotally mounted on opposed sides to the lower panel and are
movable between a first inboard position overlaying the lower panel and a second outboard position in line
with the lower panel in which the lower panel and the first and second upper panels are disposed for
receiving incident solar radiation.

The solar cells in the lower and the first and second upper panels are connected through a voltage regulator
to the storage batteries for supplying electrical energy to the batteries.

The lower and first and second upper panels are provided with releasable interlock means for releasable
interconnecting the lower panel and the first and second panels in a spaced-apart, secure manner when the
first and second upper panels are positioned in the first inboard position overlaying the lower panel.
Preferably, the interlocking means comprises interlocking tongue and groove connections mounted on the
exterior frames surrounding the lower and the first and second upper panels.

The solar panel of the present invention may be employed on any exterior surface of the vehicle, such as the
roof, hood and/or trunk. When the vehicle is not in use, the first and second upper panels of each solar panel
may be pivoted to the second outboard position so as to provide a large surface area for receiving incident
solar radiation. This provides increased electrical energy for the batteries which substantially reduces the
recharging time of the batteries and extends the driving range of the vehicle.
