INNOVATIVE MOTORLESS SOLAR TRACKING SYSTEM USING SHAPE MEMORY ALLOY

This paper presents the design and fabrication of a prototype model novel solar tracker that exploits unique properties shape memory alloy for its actuator. As against conventional trackers, proposed does not use motor changing position PV cell. The is in form spring used actuating. SMA moves panel to track Sun during day time back original at end day. structure only increases efficiency but also proves be compact, light weight robust.
