Solar tracking system with PID control of solar energy panels using servo motor

Öz

Parallel to the developing technology and the increasing population, the energy requirement is increasing day by day. Turkey's dependence on foreign sources of energy constitutes a significant budget in terms of energy costs. In this context, in Turkey, renewable energy sources with high potential are gaining importance. Fossil energy sources cause environmental pollution and threaten human health more and more every day. For this reason, the use of renewable energy sources should be encouraged and widespread. With a good energy needs analysis, producer costs will be reduced and efficiency will be increased.

Solar energy is an efficient resource in electricity generation. Increase the efficiency of the solar panels used, increases the amount of electricity produced. However, the change in the angle of the sun's rays has an adverse effect on energy production. 

In this study, it was aimed to increase the efficiency of the solar panels by moving according to angle of sunlight. For this purpose, solar panel was driven by the servo motor and it was directed to the sunlight. Servo motor's PID control was implemented using the MATLAB program. The energy analysis made is given in the results.
