The use of solar energy through photovoltaic panels has generated a supply of
energy to electrical systems in homes, which motivates to create optimal ways
for the quality of life of the human being, where his search has been oriented to
use tools innovative and latest technology for the capture of solar energy. For
this reason, work on the redesign, construction and commissioning of solar
trackers, which is aimed at the structural and mechanical redesign of solar
trackers that are in the national market. It proposes the modification of
electromechanical parts that have a high cost and also implement a mechanical
timer system that has a lower cost and does not need a power supply for its
operation, thats why the solar tracker will be used to locate the solar panel in a
position where the rays hit the surface of the cell, guaranteeing a greater uptake
of energy, which is why it is proposed to build as a prototype mobile, in
combination of the solar panel. The main purpose of this project is to obtain the
mechanical redesign of a mobile support for photovoltaic panels, with a lower
cost than the current market, this is done through computer-aided design
software (CAD), for improve their structure and generate a better linear and
circular displacement more efficient when following the sun, the simulation of
the mechanical model through Inventor software. Once this activity is carried
out, the construction of its parts is carried out and the electromechanical system
(motor) is eliminated, to implement a mechanical timer system, which is more
economical and does not require power from the batteries. Afterwards, the
efficiency tests of the system are carried out, by means of a comparative study
of the capture of the photovoltaic cells in a static support. mobile support type
solar tracker. In this way results are obtained to have a low cost device, which
can be easily acquired, by people who live in regions that do not have electrical
interconnection. In this way, the promotion of the use of alternative energies is
supported.
