Design and construction of an LDR based sun tracking system for a parabolic dish solar collector

Abstract

This project involves building a sun tracker with360 degrees capability to follow and concentrate the sun's rays. The circuit uses a voltage divider consisting of Light Dependent Resistors(LDRs) to detect the position of the sun and sends electrical signals to the window comparator which compares the signals and rotates the motor which in-turn rotates the parabolic dish so as to concentrate the sun's rays to one position(receiver). This project was successfully designed, constructed and tested. it was able to work as intended . I recommend that it can be adapted in street light solar panels and sun based heater
