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. ABSTRACT

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. INTRODUCTION

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. What is a wind turbine?

6. LITERATURE REVIEW SR NO PAPER TITLE AUTHOR PUBLISHING REVIEW 1. Automatic Dual Axis Sun Tracking System using LDR Sensor. V Sundara Siva Kumar Oct 2020 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. 2. Using miniature wind turbines in the design of experiments on wind energy Josué Njock Libii 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.

7. SR NO PAPER TITLE AUTHOR PUBLISHING REVIEW 3. HYBRID POWER GENERATION BY SOLAR TRACKING AND VERTICAL AXIS WIND TURBINE (DESIGN AND ANALYSIS) Mr. Mohammed Mustafa Aug -2019 “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. PROBLEM STATEMENT

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. OBJECTIVE

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. SCOPE OF THE PROJECT

11. WORKING DIAGRAM

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. WORKING

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. Bearings

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. ADVANTAGES

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 . APPLICATION

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 . FUTURE SCOPE

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. CONCLUSION
