MACHADO TORANZO, Noel et al. Solar tracker, optimizing ofimprovementof the solar energy. Energética [online]. 2015, vol.36, n.2, pp. 190-199. ISSN 1815-5901.

The design and implementation of a device for obtaining the coordinates of the sun at any time during the day, it means, a solar tracker of type two axis by luminous point is developed in this paper. This tracker consists of two main blocks: the controller board and the mechanical part. The design is based on the use of photoresistences, microcontrollers and stepper motors. The prototype is used on investigations about solar energy developed at the GERA (Grupo de Energía Renovable Aplicada) of Universidad de Oriente, particularly in photovoltaic panels and water heaters. An experimental test was conducted in the laboratories and at the site of the group and it was found that the solar tracker is functioning properly, meeting the desired expectations.
