Economical photovoltaic tree with improved angle of movement based sun tracking system

In this paper we propose a renewable energy storing system in order to harness optimal solar radiation. In consideration of photosynthesis process of a tree, photovoltaic cells of this artificial tree are arranged by Fibonacci pattern instead of leaves. This design will increase efficiency of storing energy compare to flat structure. To solve the problem of low efficiency of a solar system, it is necessary to orient photovoltaic cells with varying direction of periodic sun irradiation. Taking this into account, a tracking system based on one-degree angle of movement maintaining small angle of tolerance, is implemented with a specific movement flexibility for any promising fluctuation of sunlight. A incomplex techniqe and low cost design makes it economical and easy implementable.
