Desenvolvimento de um seguidor solar de baixo custo para sistemas fotovoltaicos de pequeno porte.

Abstract

A prototype of a low cost solar tracker is presented in this work, which is usually used to improve the process of capturing photovoltaic panels, ensuring the maximum use of incident solar radiation. The prototype was built using a dual-axis solar tracker model and uses simple and affordable electronic components. The constructive characteristics resulted in a low cost and easy assembly system. At current prices, the final cost of manufacture was about 10% of the amount charged for a similar model available on the international market. The complete photovoltaic system was built and simulated computationally and at the end, its effectiveness and efficiency was demonstrated, that is, the prototype was able to effectively follow the movement of the Sun and generate an increase in generation close to 16% in relation to a fixed system.
