Abstract

Objectives: This paper presents the design and construction of a solar tree to charge mobile devices on open urban areas according to the environmental conditions of Medellín, Colombia. Methods/Statistical Analysis: Based on the electric consumption calculations of mobile devices, a 3.5 m height-tree was built, with four leaves made of acrylic with solar panels on the top. It illuminates with cold white lights and four smaller leaves with green illumination. The energy storage capacity is 180 Amp, it has 6 USB ports to connect mobile devices and two 110 V-200 W electrical outlets to connect those devices to the electricity. Finally, the Photovoltaic system’s availability to satisfy the energetic requirements was verified. Findings: This research found that according to the established design variables, the system has a 3-hour autonomy on saturation and involves an energy saving of 876 Who, equivalent to 81,645.78 gr saving of emitted CO_2> in a year of operation. Improvements: As a final point, environmental, economic and social benefits are presented.
