Abstract

In this work we completed an automatic follower, the objective of which is to obtain a gain of higher energy than that obtained by a fixed solar system. Our device consists essentially of two photovoltaic panel available in our laboratory LGESE type 'AstroPower's AP-6105', which are formed of monocrystalline cell technology. The device was attached with a mechanical structure that we developed based on two DC motors with their control circuits allowing rotation of the panels in both directions horizontal and vertical. For this application, we added four sensor photo resistors with the type of 'LDR' (Light Dependent Resistor or Resistance Depending on the Light), which are arranged in a position so that their illuminations are identical only if all four sensors are pointed toward the sun. The signals from the sensors are transmitted to the inputs of a microcontroller with the type of '16F877' that allows the comparison of the levels of voltages for controlling the rotation of the two motors in order to put our system in an optimal position with the sun. To put it differently, this is done to capture and to produce maximum energy. © 2017 IEEE.
