Sun daily radiates an enormous amount of energy to Earth, and that energy is still not properly exploited, neither in World nor in India. There is no systematic stimulation for usage of solar panels, purely relying on individual cases of installation on different types of objects. Solar photovoltaic (SPV) is a land consuming system. Scarcity of land is the greatest crisis of the Earth. 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. Solar Tree is invented for installing PV-module on a tall pole-like structure with branches like panels and takes only 1% of land than conventional SPV layout. prernagaur@yahoo.com 1. INTRODUCTION The object of this work is to design an installation that, using photovoltaic panels, could provide the electricity in the areas where the electricity grid is not reachable or areas in which we don’t want to depend on it. Using the renewable energy source we’ll get services efficiently with minimum environmental impact and large savings in electricity bills [1]. Here comes the idea of a Solar Tree [2] a new invention of installing PV modules on a tall pole like structure with leaf like branches surrounding it following a pattern of spiraling phyllotaxy as found in natural tree. It would take 1% of land area in comparison to general PV system [3,4,5]. One need to erect the PV panels under the sun so that the surface of panel gets maximum sun of the day being laid at an angle. Now for an example, the generation of 2 MW power from PV module system requires the land of 10 Acres approx. for housing the panels only [6]. But land is going to be greatest crisis of the earth rather is already a burning crisis in the most of the countries [7]. The cultivable land which is going to be the costliest commodity in the near future, if used for other than agriculture, it will be uncountable loss. Our many national projects are facing the severe problem of acquisition of land. Therefore if land area is used for capturing the solar power it would never be cost effective and viable for the human society [8, 9]. Therefore there is a need for devising a method and fabricating a suitable device so that the solar power can be absorbed without occupying much surface area, rather utilizing he minimum amount of land and the electricity must be economically viable [10]. 2. SOLAR POWER The energy emitted by sun within three minutes is equivalent to the world energy consumption during a year. Solar energy is unique source which can be exploited in many different ways as one such way is Photovoltaic conversion [11]: In Photovoltaic conversion, solar radiation falls on semiconductor devices called solar cells which convert sunlight directly into electricity [12, 13]. When light falls on the junction between two types of semiconductor called p-type and N-type-type has an excess of electrons and P-type has a shortage of electrons. When a bright light shines on a cell, energy from the light (photons) enables electrons to break free from the junction between them. This is called photoelectric effect. The flow of electrons constitutes an electric current stored in batteries. Photovoltaic effect is shown in the Fig. 1. Fig. 1: Photovoltaic Effect 3. INSPIRATION The idea for this project started with the following hypothesis. If we build a solar tree using solar panel in which each element follows the distribution of leaves in a tree, we will have good performance in capturing electromagnetic waves. Tree can produce their food material by the process called PHOTOSYNTHESIS.
