AUTOMATION FOR SOLAR TRACKER FOR PANEL PHOTOVOLTAIC – EFFICIENCY ANALYSIS

Abstract

This article presents the results of a prototype of electronic circuit boards for photovoltaic solar tracker based on a microcontroller circuit and sensors that has its analog voltage compared periodically. That sensor that has the highest incidence of the sun, great angle with reference to the solar panel can have the greatest absorption solar energy and consequently have the highest possible power transference that moment. Three different panoramas are studies: one panel installation on a roof random, another under the guidelines of the manufacturer and a third with the solar tracker. The results presented show a performance of automated solar panel with 27% higher than according to the manufacturer's guidelines and more than 110% of that installed on a roof arbitrary, justifying its application in relation to the costs involved, especially in small systems.
