The proposed Dual axis solar tracker devices ensures the optimization of the conversion of solar energy into
electricity by properly place the PV panel in accordance with the real position of the sun. In this system used servo
motor to controlled by a dedicated drive unit that moves a PV panel according to the signals received from two simple
but efficient light sensors. In this proposed system the solar panels exactly in front of sun.PIR SENSOR used in system
with purpose of activation of led street light only when on object is passing through subjected peripheral of street light so
we can store energy for further usage and will be useful to prolong the utilization time of street light.
