The solar energy is a clean,freely and abundantly available alternative energy source in nature. Capt uring solar energy from nature is an advantageous task fo r power generation. Conversion of sun energy into another form is a highly complex phenomenon. For th is purpose,Photo-Voltaic (PV) panels are used which convert Sun energy to Direct Current (DC) ele ctrical energy. Conventional fixed type PV panels extract maximum energy only during 12 noon to 2 PM which results in less efficiency. Therefore,buildi ng of an automatic solar tracking system is the need o f an hour. PV panels have to be perpendicular with the sun for maximum energy extraction which can be fulf illed by automatic tracking. This project includes the design and development of microcontroller based aut omatic solar tracking system. Light Dependent Resistors (LDRs) are used to sense the intensity of sunlight and hence the sun�s position in the sky. Microcontroller AT89S52 is used for controlling the movement of PV panel. The mechanism uses geared DC motors to rotate the PV panel. DC motors are con trolled by the microcontroller with respect to sign als from LDR. Zigbee transmitter - receiver pair is imp lemented to receive the data from remote location (plant) i.e. for data acquisition purpose. Liquid C rystal Display (LCD) is used to display the output DC voltage and current on site whereas at the supervis ing location using Visual Basic (VB) data is acquir ed,stored and displayed. https://www.ijiert.org/paper-details?paper_id=140505
