India is a densely populated Electric energy demand is increasing over the country the advantage of such energy source which decades and to fulfil the required demand we have into account that requires a very less space to to concentrate on utilizing non-conventional produce energy efficiently. A solar tree is most sources of energy. India being a highly populated relevant and economical way of harnessing the country, so it is essential to take the advantage of solar energy. It can harness the energy occupying such an energy source which requires a very less less space as compared to other traditional space to produce energy efficiently. This methods. An attempt is made to design and arrangement of solar panels called “Spiralling fabricate solar trees for the remotely located Phyllotaxy” improves the efficiency of the tree. It individual households by reducing or avoiding the can be applied in street lightening system, regular electric energy consumption. Considering industrial power supply, remote areas etc. It is a the minimum power requirement for a single very good option for implementation and requires household, the tracking however being passive in less space than other conventional energy nature requires energy input for operation which equipment as space availability is the main problem becomes a liability from the point of the total in many cities. India being a developing country energy output. The solar tree designs are an effort and thickly populated requires power generation in the same direction. Solar tree is an innovative plants that can generate maximum energy by concept of arranging the Photo voltaic (PV) panels. utilizing minimum land area. Hence, solar tree will Single converter cell is called a solar cell or more be the best options to avoid overcome the land generally, a photo voltaic cell. A combination of utilization problem. such cells, designed to increase the electric power Keywords- solar panels, solar charge controller, output is called a solar module or solar array. Solar battery, inverter, etc. energy emits far less harmful emissions than fossil fuel energy sources. They generate electricity by I.INTRODUCTION converting photons of light into electrons. Solar cells produce direct current. This DC current is Solar tree is a metal structure that has solar panels converted to alternating current, by using inverter. at the top instead of branches of a real tree. Solar Solar tracking systems are utilized to continually energy is collected by solar panels and converted orient photovoltaic panels to the sun and can help into electricity and uses it for storage in battery, make best use of the investment in Solar Power charging of mobile phones, portable computer and Tree. Solar trackers generate more electricity than tablets. With growing population there is a huge their stationary counterparts due to an increased demand and necessity for large amounts of energy. direct exposure to solar rays. Solar trackers are Also, the sources to produce these energies are highly efficient installations. Some require such a decreasing day by day based on energy demand a plant that can generate maximum energy using renewable option of energy sources must be taken minimum land. It can generate energy very into consideration keeping in mind that energy efficiently as compared to traditional system. generation should not cause pollution and other www.jespublication.com Page No:592 Vol 11, Issue 7,July/ 2020 ISSN NO: 0377-9254 Fig.1 Block Diagram This is like a tree in structure and the panels are A solar tree is a decorative means of producing like leaves of the tree that produces energy. solar energy and also electricity. It uses multiple For traditional system we require large area of land numbers of solar panels which forms the shape of a to generate 1 KW power from PV module. In tree. The panels are arranged in general, we require 10 to 12 sq. Feet of land area to a tree fashion on a tall tower/pole. generate energy very efficiently as compare to TREE stands for traditional system. Due to the technique called T = TREE THAT GENERATES spiralling, its efficiency further increases though it R = RENEWABLE is somewhat costly. But when compared to E = ENERGY which can be converted to traditional system it is more efficient.

This is the best option of energy Tasic, and S. Zecevic, discuss in their paper titled generation because it requires very less land area as “Implementation of the Project “Solar tree” compared to the traditional PV system. Nowadays published in International Journal of Scientific & land area has become very expensive especially in Engineering Research, Volume 7, Issue 10, cities because of high population growth. Some October-2016, 1319 ISSN 2229-5518 about a new urban areas require such a plant that can generate product called, ‘solar tree’ that has been designed maximum energy using minimum land. It can to increase the power output by many folds by generate energy very efficiently as compared to consuming solar energy. It can be installed on the traditional system. sides of heavy traffic roadways and on roof top of Solar panels are devices that convert light buildings. This tree consists of numerous solar into electricity. They are termed “Solar” panels panels connected to one another in series as well as because most of the time, the most powerful source parallel connections. The solar tree consists of of light available is the Sun. Some scientists call number of branches welded to a metal stem and them photovoltaic which means, basically, “light- each stem has a solar panel mounted on it. It adds electricity.” A solar panel is a collection of solar up the voltage in series and current in parallel cells. Lots of small solar cells spread over a large connection. The paper presents calculation of the area can work together to provide energy that sun earth angles at different times of the day and would be useful. The more the light a solar cell designs the solar tree based on these sun earth receives more the electricity it produces. angles. The panels are placed on the structure in a spiral fashion. It proves to be a useful system to II. REVIEW OF LITERATURE meet the energy demands of the world and to use a given space more efficiently. The present system of Deepak M. Patil, Santosh R. and Madiwal roof top solar systems can be replaced by solar tree discuss in their publication titled, “Design and and the roof top space can be utilized for recreation Development of Solar Tree for Domestic purposes. The solar tree can be installed on the Applications’’, published in International Journal ground too. Also, in addition these roof top spaces of Engineering Sciences & Research Technology, can be used for other purposes. So this solar tree August 2016 ISSN: 22779655, about the solar tree proves to be advantageous both in saving space and with flat or roof top mountings of PV systems. This increasing the power output by many folds. It saves requires large area of land. Scarcity of land area is a lot of energy over the years to come. The number the greatest problem in cities and even in villages of solar trees that could be installed in a given in India. Solar Power Tree provides better space depends on the wattage needed. alternative to flat mounting of PV systems. For Sushma Gupta, Monish Gupta, V.

The solar tree concept is very supply is decreasing. Therefore, energy sources are successful to fulfil the increasing energy demand of becoming limited throughout the world. Hence this the people, saving of land and should be Solar Tree proves to be the most beneficial source implemented in India to provide electricity without of energy. This paper presents the Solar Tree the problem of power cut-off and reduce the implementation as an alternate source of energy in dependence on grid power. Daily average energy urban cities. A new idea of a solar tree design using requirement of the small Indian family is calculated Nano wire solar cell is presented. Nano wires to be about 3.5kW. Such systems can be mounted possess high physical light absorption properties on the terrace, in front of the house or near the wall which can be improved tremendously. Hence, they avoiding shade areas. The initial investment cost of say that it is a revolutionary urban lighting concept the solar tree is also equal to the same capacity PV and these technologies lead to the development of systems as other system components are similar. high efficiency solar energy.
