Block Diagram Of Automatic Solar Tracking System

Solar tracking enables more energy to be generated because the solar panel is always able to maintain a perpendicular profile to the sun s rays.

Block diagram of automatic solar tracking system.

Aim of the project 3. Automatic solar tracking system 1. This project deals with a rtc based solar panel tracking system. The circuit design of solar tracker is simple but setting up the system must be done carefully.

Above can be solved by our system by automatic tracking the solar energy. The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components. 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.

The pwm inputs of two servos are given from digital pins 9 and 10 of arduino. Project presentation on presented by anuj kumar arvindra kumar ram swraoop 8th semester 2013 2014 submitted to er. 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. Controller then takes the decision according.

1 shows the circuit of the 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. Development of solar panel tracking systems has been ongoing for several years now.
