Block Diagram Of Automatic Solar Tracking System

The circuit design of solar tracker is simple but setting up the system must be done carefully.

Block diagram of automatic solar tracking system.

Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position. 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. The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components. Automatic solar tracking system 1.

Above can be solved by our system by automatic tracking the solar energy. 1 shows the circuit of the solar 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. Development of solar panel tracking systems has been ongoing for several years now.

The pwm inputs of two servos are given from digital pins 9 and 10 of arduino. Aim of the project 3. Solar tracking system circuit fig. Project presentation on presented by anuj kumar arvindra kumar ram swraoop 8th semester 2013 2014 submitted to er.

Circuit of solar tracking system. This project deals with a rtc based solar panel tracking system. 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.
