Implementation of Sun Tracking for Solar Cell with Maximum Power Point Tracking

Abstract:

In this paper, the implement of the solar cell for sun tracking is achieved. The sun energy is abundant with clean and green energy, but the efficiency is not benefit from the source of solar panel to the power conversion output for the practical application. This paper contains the implement starting from driving solar cell with the XY-axis servo motor to trace the optimal input solar light, then the maximum power point tracking circuit (MPPT) in the Boost conversion is included to increase the efficiency for lithium battery charging. The super capacitor banks are paralleled with the lithium battery to improve the inrush power load, which is benefit for prolong the lithium battery and solar panel life; The applications of output are included two parts; one is the small green man of traffic light and the other one is AC 110V urban electric conversion; the control core for this system is PSOC chip for its simple, practical and high efficiency demand.
