Solar trackers

The solar tracker is a technological device with capacity to orientate towards the Sun, that is, to follow the Sun from sunrise to sunset.

Due to its rotation, the photovoltaic walls are directed directly to the Sun the whole day and this increases its performance up to 38 % with regard to a fixed structure.

Depending on the performance that wants to be reached, it is possible to choose between the following types:

  • In two axes (2x): the surface is kept always perpendicular to the Sun. There are two types:
  1. Single post: a unique central support.
  2. Carrousel: several supports distributed along a circular surface.
  • In a polar axis (1xp): the surface rotates over an axis orientated to the south and inclined an equal angle to the latitude. The rotation adjusts so that the normal to the surface coincides at all time with the terrestrial meridian that contains the Sun. The speed of rotation is 15 ° per hour, as that of the clock.
  • In a horizontal axis (1xh): the surface rotates over a horizontal axis and orientated in direction north – south. The rotation adjusts so that the normal to the surface coincides at all time with the meridian that contains the Sun.
  • In an azimutal axis (1xa): the surface rotates over a vertical axis, the angle of the surface is constant and equal to the latitude. The rotation adjusts so that the normal to the surface coincides at all time with the local meridian that contains the Sun. The speed of rotation varies throughout the day.
