Abstract: In our Dual axis automatic solar tracker project, AT89S52 micro-controller has been used. Four photo-sensors (LDR VAC54) are used for sensing the sunlight to know sun’s movement. Two gear motors (12V, 300 rpm) are there to rotate the solar panel (E-W and N-S) as the sun changes its direction. ADC chip 0808 is used to decode analog voltage to digital voltage. PROTEUS software coding has been used for designing and simulating the tracker. Photo sensors, battery charging level and solar panel voltage will be monitored by the micro-controller through ADC chip. Attempts have been made to make this pilot project cost-effective with successful completion for standalone systems and can be expanded further for grid connectivity.
