Block diagram of automatic solar tracking system.

Bindu ji gyanesh er. Development of solar panel tracking systems has been ongoing for several years now. This project deals with a rtc based solar panel tracking system. The block diagram below shows system architecture 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.

1 shows the circuit of the solar tracking system. Aim of the project 3. Solar tracking system circuit fig. 2 3 block diagram of dual axis sun tracking system the block diagram of dual axis solar tracker is shown in figure 1 and the designed tracking system consists of ve light sensors ldrs of which four on four sides of the solar panel i e on east west and north south directions and the remaining one in centre of the panel.

Circuit of solar tracking system. Four ldrs and four 100kω resistors are connected in a voltage divider fashion and the output is given to 4 analog input pins of arduino. Project presentation on presented by anuj kumar arvindra kumar ram swraoop 8th semester 2013 2014 submitted to er. Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position.

The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components. Controller then takes the decision according. The pwm inputs of two servos are given from digital pins 9 and 10 of arduino.
