Design & Development of Low Cost Solar Tracker Using Microcontroller
This Paper covers the control system design and implementation of the Sun-tracker. The approach presented is simple and low cost for domestic application. Digital control implementation make system works in adverse conditions. Dynamics of solar panel mount are discussed and sun sensor design is presented. PD controller is designed to decrease oscillations and reduce settling time up to 2s. Battery charging circuit designed is incorporated with features like battery thermal protection, day/night switching and battery voltage level display.
