Abstract

This article presents the design and practical implementation of a dual-axis solar tracker using low-cost components and recyclable materials. The prototype has an open and circular structure, offering a natural cooling. The tilting of the photovoltaic panel is performed using two servomotors to obtain highest intensity of sunlight captured by 4 LDR sensors, placed to the left of the panel and separated by two opaque barriers, generating the shadow caused by the sun movement. For the system supervision and control, a Scada was developed using the ScadaBR. The prototype was tested and results compared, considering a system with fixed panel, one and dual-axis tracker. Results showed that the dual-axis tracker system proved to be more efficient, considering a generated voltage, around a 12, 45% compared to the single-axis tracker.
