5 Wp PV module-based stand-alone solar tracking system

5 Watt-PV module is utilized for tracking solar oven concentrator system with 2.6 kW/sub th/ capacity and 200 Kg weight. The tracking system follows the sun autonomously in altitude and azimuth using only 5 Watt-peak PV solar module as a tracking energy source. The tracking system is driven by means of two 12 DCV motors of 36 W each, and fed by electrolytic condenser with 78000 /spl mu/Fd capacity charged properly by PV module. The PV based tracking system has two circuits in bridge, configuration using N- and P-channel power MOSFET transistors. This electronic circuit commands DC motor rotation way, as a function of the optical sensors for altitude and azimuth position.
