    •  Today’s time solar cells are becoming extremely popular for utilizing solar energy to use in different ways such as producing electricity, transportation,cooking etc .  So many solar panels have been installed all over the world and most of them are stable. They are installed in the direction of maximum radiation of sunlight.  Now the problem arises that the sun is moving .So we cannot use maximum radiation of sun all the time. The position of maximum radiation receiving position only comes once in 24 hours. 3
    •  Solar tracker is the best solution for receiving maximum radiation.  By moving the solar panel according to the movement of sun we can always receive the maximum radiation . 4
    • • The earth receives 16 x 1018 units of energy from the sun annually, which is 20,000 times the requirement of mankind on the Earth. • Solar panels are used to convert light energy into electrical energy. • Efficient Solar Power generation System using moving panel is a efficientpower generating system using sun light.  Two sensors in two directions to sense the direction of maximum intensity of light. The difference between the outputs of the sensors is given to the microcontroller unit. 5
    •  Microcontroller is used to process the input voltage from the comparison circuit and control the direction in which the motor has to be rotated so that it will receive maximum intensity of light from the sun.  The power generated from this process is then stored in a lead acid battery.  Stored energy is used to run different appliances 6

    •  It consist of a LDR sensor senses max solar power which is being given to the Microcontroller through the ADC which digitizes the LDR output.  Controller then takes the decision according to then algorithm and tilts the panel towards the direction of the max energy given by LDR with the help of DC Motor .  The Motor is used to rotate the LDR to sense the max solar power. 8
    •  On the monitoring station which receives the data send by the system.  This data is logged into the PC.  The RS232 converter is used to connect the microcontroller to PC which convert PC"s CMOS level to Controller"s TTL level n vice versa.  Limit sensors or Touch sensors are provided to sense the starting and ending position of the solar panel.  Keypad is provided to adjust the starting position of the solar panel. 9

    • Microcontroller(AT89C2051)  low-voltage, high-performance CMOS 8-bit microcomputer  2K bytes of Flash programmable and erasable (PEROM). read-only memory  128 bytes of RAM, 15 I/O lines, two 16-bit timer/counters.  a five vector architecture. two-level interrupt 12
    • 555 TIMER IC functioning as an accurate time-delay generator .  Timing from micro seconds through       hours Monostable and Astable operation Adjustable duty cycle Ability to operate from a wide range of supply voltages High current output that can sink or source 200 Ma Output can be operated normal ON and OFF High temperature stability 13
    • Solar Panel  Collection of photovoltaic cells.  Photovoltaic cell is composed of sillicon  Used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications.  Rated by its DC output power under standard test conditions, and typically ranges from 100 to 320 watts.  Consists array of solar panels, an inverter, and sometimes a battery and or solar tracker and interconnection wiring.  The efficiency of a panel determines the area of a panel 14
    • Stepper Motor • electromechanical device which converts electrical pulses into discrete mechanical movements. The speed of the motor shafts rotation is directly related to the frequency of the input pulses and the length of rotation is directly related to the number of input pulses applied. Lead Acid Battery• very low energy-to-weight ratio and a low energy-to- volume ratio, their ability to supply high surge currents means that the cells maintain a relatively large power-to-weight ratio. These features, along with their low cost, make them attractive for use in motor vehicles to provide the high current required by automobile starter motors. 15
    •  Microcontroller kit or Atmel AT89C2051 microcontroller.  Keil Micro Vision Integrated Development Environment.  C51 C Compiler, A51 Assembler. 16
    •  Technical/practical : 1.Pollution free 2.Safety in Design 3.Usability 4.Reliable 5.Reduce human error 6.Portable  Economical: 1.Total cost of project=6000/17
    •  Heating the water  Electric fence  Battery charger  Emergency battery backup  Solar cooker 18
    •  To improve the sun tracking, a stand alone sun tracker can be designed using 18 seriesPIC microcontroller.  In 18 series PIC microcontroller, data can be stored periodically in MMC card .We need not to do it manually (no need of rotation). 19
