Solar tracker
The solar tracker provides a much higher energy yield than fixed installations because, like a sunflower, it offers tracking of the sun's path following a motorized axis and generally for personal use a manual seasonal axis.
Indeed, if a photovoltaic module remains perpendicular to solar radiation during the day, its productivity increases:
With a movement following the azimuth from east to west, production can increase by 27 to 32% compared to the production of a fixed module.
With movement on 2 axes, azimuth and elevation, the annual production increase can reach 40% compared to the production of a fixed module.
The Etatrack range of solar trackers from the German manufacturer Lorentz offers 3 products powered by maintenance-free technology with single-axis pivoting. A solar panel is used as a sensor and electricity source for the drive motor.
- Etatrack active 400: total solar module area max. 4.0 m², approximately 500 Wp
- Etatrack active 1000: total solar module area max. 10.0 m², approximately 1.6 kWp
- Etatrack active 1500: total solar module area max. 15.0 m², approximately 2.4 kWp
