Structural Design and Analysis of Trailer System for Photo Voltaic Cells

Abstract

Non conventional power devices viz. Photo voltaic cells are not seeing much of light due to a practical draw back that sun should be normal to the plane of the device all the times. But presently non conventional power devices are being installed in a fixed position and in a day, position of sun keeps changes from morning till evening with relative to the non conventional power device. Because of this practical difficulty most of the time very minimal power that emits from the sun will be utilized for generating electricity. To overcome this limitation a trailer system is needed which enables the non conventional power device to change its orientation (Rotates) continuously such that it always remains normal to the sun with which effectiveness of the non conventional power devices can be increased tremendously. Existing systems are having electronic controllers which are complex to handle and also costlier. Moreover they demand more power for their own controller and also their maintenance is tedious. Hence a trailer system which dispenses utility of so called complex electronic controller through the aid of mechanical elements is evolved for non conventional power applications. To start with all the subsystems of the proposed configuration are identified and sizing is evolved through design calculations. Further design adequacy has been assessed through Finite Element Analysis.
