Tracking Systems for Solar Parks Tracking systems allow increased returns on invest- Reliable, high life expectancy reliable control concepts for installations of all Fast and failure-free installation arantee highest energy yields – all around the year. Excellent serviceability Short Return of Investment (ROI) cycle Lower Total Cost of Ownership (TCO) First-rate price-performance ratio ment. Thanks to their robust mechanics and their sizes, LORENTZ tracking systems for solar parks gu- LORENTZ solar park tracking systems are based on the tracking system ETATRACK active, successfully operating worldwide since more than 10 years. LORENTZ provides optimised control concepts for solar parks of different sizes. Statics according to German and European standards. To nd out more visit www.lorentz.de BERNT LORENTZ GmbH & Co.

Outer dimensions depend on PV module size. Dimensions given here are exemplary for standard PV module size 1.6 m × 0.8 m ETATRACK active 1500-A SP 4.8 Spatial Requirements LORENTZ solar parks are spatial-optimised to achieve highest yields on a given space. For smaller distances between the units, mutual shadowing is avoided by optimised tracking movements.
