Abstract

The importance of solar tracking systems lies in the need to optimize the amount of solar radiation on solar collectors of different types. In this work, the monthly mean daily irradiation was analyzed on a flat surface of unitary area, under different tracking schemes of the Sun, by means of the use of a numerical model. For this purpose, solarimetric data was obtained from some stations of the new Mexican Solarimetric Network, the solar irradiance incident on a flat horizontal plate was calculated. Also, the movement of some tracking systems was carried out in steps with different time intervals in order to compare it with their respective continuous movement. It was found that stepped movements report yearly incident solar irradiation values above 98% respect to continuous movement in the widest interval.
