We can also use the technique called “SPIRALLING PHYLLATAXY” to improve the efficiency of the plant . It is much better than the traditional solar PV system in area point of view and also more efficient . industrial power supply etc. It can be applied in street lightening system . So this will be a very good option and should be implemented . so we should take the advantage of such an energy which requires a very less space to produce energy efficiently . In this case solar tree could be the best one for us .ABSTRACT Now a days with the growing population and energy demand we should take a renewable option of energy source and also we should keep in mind that energy should not cause pollution and other natural hazards. India is a highly populated country . In this case the solar energy is the best option for us. 6 . CONTENTS • • • • • • • • • • • • • • • Introduction What is a solar tree? Why we called it as tree?

Solar energy is available in abundance and considered as the easiest and cleanest means of tapping the renewable energy. The temperature of interior of sun is estimated at 8*10^6 k to 40*10^6 k.INTRODUCTION It is a form of renewable energy resource that is some measure competitive with fossil fuels. Hydro electric power plants do not use any resources to create electricity or they do not pollute the air. 8 . However the main problem associated with tapping solar energy is the requirement to install large solar collectors requires a very big space. where energy is released by fusion of hydrogen and helium. Hydro power is the force of energy of moving water. solar photovoltaic and solar architecture. The sun is a hydrodynamic spherical body of extremely hot ionized gases(plasma). For direct conversion of solar radiation into usable form. It provides about 96% of the renewable energy in the united state. the routes are: solar thermal. To avoid this problem we can install a solar tree in spite of a no of solar panels which require a very small space. generating energy by the process of the thermonuclear fusion. 9 . TREE stands for T= TREE GENERATING R=RENEWABLE E=ENERGY and E=ELECTRICITY This is like a tree in structure and the panels are like leaves of the tree which produces energy.WHAT IS A SOLAR TREE A solar tree is a decorative means of producing solar energy and also electricity. It uses multiple no of solar panels which forms the shape of a tree. The panels are arranged in a tree fashion in a tall tower/pole. WHY WE CALLED IT AS SOLAR TREE As we know trees are present in nature and they can produce their own food material by the process called PHOTOSYNTHESIS. Green leaves are producing food materials for human beings likewise this leaves are producing energy for the society. 10 . So it is very appropriate to called it as a tree. By this process they are indirectly providing food to the human society because we are depending on the green plants for our food directly or indirectly. This is a tree in which the stems connected acts as the branches of the tree and the solar panels are like the leaves. Here we are considering the example for understanding about the solar tree. It is the process by which the green plant collects energy from sun and the water present in soil at the day time and can produces their own food material. Now a day’s land becomes the costliest commodity for the human society because of high population growth. Though it is somehow costly but as compare to all cost involve in traditional system it is more efficient. The stem are flexible so that they can rotate in any direction and by shaking themselves they produce energy also from wind as in the case of a natural tree. Due to the technique called spiraling phyllataxy its efficiency further increase. It can collect energy from wind: As the name suggest this is a device to generate energy from sun but it has some unique feature to generate energy from wind. So we require such a plant which can generate maximum energy using minimum land.WHY IT IS NEEDED Due to less land requirement: It is the best option of energy generation because it requires very less land as compare to the traditional PV system. Efficient energy generation: It can generate energy very efficiently as compare to traditional system. 11 . CONSTRUCTION AND WORKING The solar tree consists of some important parts in its design. They are as follows Solar panels Long tower LDEs Batteries Stems for connecting the panels WORKING: • • • • Batteries are charged during the day time. 12 . LEDs are automatically switched on These are used to indicate how much charge/energy remain left Batteries are also used to store the energy so that we can use it at night and in cloudy days when no sunlight is there. it provides the way to help the lower panels from the shadow of upper ones. It requires about 1% land as compare to the traditional system.12 acres of land in case of solar tree. so that it can track maximum power from sun. SPIRALLING PHYLLATAXY It is a technique used in designing of solar tree .10-0. Example – To generate 2 MW power from a pv module we requires 10 -12 acres of land for housing of panels only. But for the same amount of energy we require only 0.WHY IT IS BETTER THAN A TRADITIONAL SYSTEM For the traditional system we require large size of land to generate a small amount of power. 13 . 14 . ADVANTAGES • • • • • No air pollution We wouldn’t have to worry as much about future energy sources People in poor country would have access to electricity People can save money Land requirement is very less DISADVANTAGES • • • Cost is high May cause hazards to the birds and insects Hazards to eyesight from solar reflectors APPLICATION • • Street light House supply 15 .WHY IT IS UNIQUE The unique technique is that flexible panels connected to the stem which can be rotated as our desire. So that flexibility avoidance of wind pressure can be possible. Flexibility offers manual rotating so that maximum power can be obtained. This can provide electricity without any power cut problem. CONCLUSION To fulfil the increasing energy demand the people and saving of land this project is very successful one. 16 . We must try to produce energy from sun by using solar tree in our country to increase our per capita land and fulfil the growing energy demand. The extra energy can be provided to the grid. Solar tree will be the best option to avoid this problem.• Industrial power supply SOLAR TREE IN INDIA India being a developing country and highly populated requires a power plant where maximum energy can be generated by using minimum land.
