Abstract

The goal of this paper is to present the building of a quadrant sensor based on an ultra low power microcontroller. The application of this sensor is a solar tracker system, and we will optimize it by comparing fixed solar panel efficiency versus a solar panel equipped with a solar tracker, based on an energetic balance. The related quality of services is fulfilled by functions dedicated to time related coordinates correction. The main requirements in solar cells system optimization are related to lifetime, reliability, robustness and quality of services. The life expectancy of the system is improved by using a microcontroller- based implementation. Our solar tracker implementation is used for orienting systems like day light reflectors or photovoltaic cells toward the sun, with some major additional improved functions in respect with the amelioration of reliability and robustness. The implementation of solar tracker system is based on a microcontroller, two servo motors and four photo resistors that are used as two half bridges sensors.
