GONZALEZ MENDOZA, J. M; PALACIOS MONTUFAR, C  and  FLORES CAMPOS, J. A. Analytical synthesis for four-bar mechanisms used in a pseudo-equatorial solar tracker. Ing. Investig. [online]. 2013, vol.33, n.3, pp.55-60. ISSN 0120-5609.

Photovoltaic energy production systems generate electricity without emitting pollutants into the atmosphere and do so from a free, unlimited resource. The highest level of energy conversion from the photovoltaic panels can be obtained by placing them perpendicular to the sun's rays falling on their surface; this is done by installing solar tracking systems. This work proposes the use of two four-bar mechanisms as the driving force for a solar tracker; we propose the use of analytical synthesis for such mechanisms. This procedure is aimed at optimising the transmission angle, increasing mechanical advantage and decreasing driving torque. A mathematical model was used to prove synthesis results and a prototype of the solar tracker was built.

Keywords : Transmission angle; four-bar mechanisms; solar tracker, synthesis.
