Design and implementation of a solar tree structure for efficient LED street lighting

Abstract

This paper shows the design of solar tree PV system for street lighting. In current days with enhancing the population and the energy demand, the Renewable Energy Source (RES) plays a major role and also, this energy could not cause any pollution and other natural hazards. The solar energy is more suitable one for this among other RES. India is a highly populated country, so the merit of such a solar energy that needs a very small space to produce energy efficiently. Flat or roof top mountings of PV systems are needed large land areas and problems in production of PV systems voltage due to partial shading of PV panels. Also, the scarcity of land is greatest problem in cities and particularly in urban areas in India. In order to overcome these harms, Solar Tree Structure Power Generation (STSPG) is developed. Hence, this article presents a design and fabrication of 120 Watts STSPG pilot plant for efficient LED street light application. The design structure of STSPG includes the support structure used to represent the leaves, the height, orientation and tilt angle of these leaves.
