3.  To generate the electricity with the help of VAWT (Vertical axis wind
turbine).
 The VAWT is use for generate the 10watt D.C. power & LED is turn on.
 A VAWT does not need to be oriented into the wind a the power transition
mechanisms can be mounted at ground level for easy access.
 For generating the power it is depend on the velocity of the wind. But we
assured that VAWT is generate the fixed D.C. output which is depend on
the velocity of the wind.

4.  Wind power turbines come in handy in the market today. Vertical-axis wind
turbine happens to be one of the most popular and widely coveted wind
turbines.
 It is also more practical, reliable and cost effective has the best longevity
and durability features. Therefore, you will be able to use it efficiently over
a long haul.
 Solar energy is one of the primary sources of clean, abundant and
inexhaustible energy that not only provides alternative energy resources,
but also improves environmental pollution.
 Solar tracking is the most appropriate technology to enhance the electricity
production of a PV system.

5.  A wind turbine is a system which transforms the kinetic energy available in
the wind into mechanical or electrical energy that can be harnessed for any
required applications.
 Mechanical energy is most commonly used for pumping water. Wind
electric turbines generate electricity that can be utilized locally or
transported to the desired location through grid.

To present this efficient solar distributed generation
system, a dual-axis solar tracker is designed. The tracker
actively tracks the sun and changes its position accordingly
to maximize the power output. The designed tracking
system consists of sensors, microcontroller operated control
circuits to drive DC motors and gear- bearing arrangements
with supports and mountings. Two geared dc motors are
used to move the solar panel so that sun’s beam is able to
remain aligned with the solar panel.

2021 Miniature wind turbines were designed, built, analysed and
tested as part of mini projects that are embedded in a fluid
mechanics laboratory course at the Junior level. These
turbines were used by engineering students in experiments
that investigated the influence of many variables that affect
the power produced by a wind turbine.

“Hybrid Power Generation by Solar Tracking and Vertical
Axis Wind Turbine” wherein, design of the components and
their analysis has been carried out and, the fabrication of
the model has been done as per the calculations that have
been obtained from the design and analysis.

8.  Develop a mechanism that would vary the position of vertical axis wind
turbines to maximize electrical output in any wind condition.
 Energy plays an important role in everyday life to carry out any task. The
non-renewable energy resources such as oil, coal and gas are majorly used
as energy nowadays.
 The main problem behind the non-renewable energy resources are not
sustainable and create global warming which is hazardous to the
environment.
 Also to fabricate the model of the same which would able to show the
characteristics of systems and working according to need.

9.  To design and construct a simple solar tracking system which can absorb
maximum amount of sunlight.
 To minimize the cost of installation and operation providing higher
reliability.
 This project focused on increasing the efficiency of using wind energy by
producing large amount of electricity and reduces the space for installation.
 The vertical axis wind turbine is highly used for domestic applications where the
volume of production is low and efficiency is optimal while the horizontal axis
wind turbine is widely for larger volume of production requires huge investment
and the efficiency is high.

10.  It is the design method for maximum conversion efficiency of a turbine for
delivering the maximum power to a load, battery, in the case of a stand
alone wind system.
 Saves space.
 It doesn’t require fuel.
 The efficiency of VAWT is optimal so it cannot be utilize for larger volume of
production. The main advantages of VAWT compared with HAWT are generation
of electricity at ground level and the way of installation is simple.

12.  light dependent resistors (LDR) is used as sensors to track the sun’s exact
position senses the position o the sun in vertical axis This information is
then passed to the light comparison unit.
 The rest LDR senses the night mode and the signal is sent to the light
comparison unit. A light dependent resistor (LDR) is a resistor whose
resistance decreases with increasing incident light intensity.
 Microcontroller is the main control unit of this whole system. The output
from the light comparison unit comes to the input of the microcontroller
which determines the direction of the movement of the motors in the
vertical axes.
 For this project 8051microcontroller is use. The design of the light sensor
is based on the use of the shadow.
 If the PV panel is not perpendicular to the sunlight, the shadow of the
cylinder will cover one LDRs and this causes different light intensity to be
received by the sensing device.

13.  Frame:
 L Channel- MS Angles are L-shaped structural steel represented by
dimension of sides & thickness.
 25x25x3 means, both the sides of angles are 25 mm & thickness is of 3
mm.

14. It consists of the following main parts:
 Solar panel:
The solar panels are used to generate electric power.
The photo- voltaic effect can be observed in nature in a variety of
materials that have shown that the best performance in sunlight

15.  DC MOTOR
 A DC motor is any of class of electrical machines that converts the direct
current electric power into mechanical power.
 It produce rotary motion; a linear motor directly produces force and
motion in a straight line.
 In Bottle filling machine the dc motor is used to rotate the conveyor belt at
a desired speed which is fully controlled By Microcontroller.
 SPECIFICATION:
 12 volt
 30 r .p .m

16.  Bearing are required to mount the shaft to the frame stand. The use of
bearings is to provide the end supports to the shafts as well as to provide a
relative movable support. So that the pulley can rotate about its axis.
 We use here roller contact bearing of ball type. The shaft diameter is 15
mm so requires bearing has to be 15 mm inside diameter.
 According to bearing designation, 6002 will be appropriate for this
assembly. As it have 15 mm inside diameter to mount the pulley shaft. Here
we have two pulleys giving us two shafts which has four ends, so quantity
of bearings required is 4.

17.  Design for easy to operate, servicing and maintenance where required.
 Most Eco-friendly & clean source of power.
 No pollution and no recurring fuel costs, highly reliable and consistent
power supply.
 Long life span for SPV modules & Modular design.
 Very few moving parts negligible maintenance required.
 Increases public safety and aids in providing a safe working environment
in areas where mains power is risky.
 Low Height required.

18.  Vertical axis wind turbine sun tracker can be used for large & medium
scale power generations.
 It can also be used for power generation at remote places.
 It may be used as domestic backup power systems.
 It can be used in solar street lighting system It may be used in water
treatment technologies and solar heating.

19.  In past days VAWT had to be start by giving excitation.
 Our project aspect is to make self starting vertical axis wind turbine.
 And second one is to reduce the power fluctuation due to the uneven wind.
so, that we get constant power supply.
 For that, We will put a gear-box between turbine & rotor shaft.

20.  The proposed vertical axis wind turbine solar tracking system will be
reliable and accurate throughout the year and maximize the output power
when compared to static system and single axis tracking system.
 It will be a good and competitive solution for the market place as it is
expected to compete with more complex and expensive systems.
