IDEEMATEC‘s innovative high-span safeTrack H4 tracker™ offers an outstanding design DNA. As first two-in-portrait tracker in the market, powered by its core patented drive technology, IDEEMATEC’s solar tracker offers a superior safety and uptime level. Now available safeTrack H4PLUS bifacial tracker™ for an even higher yield at maximum reduced shading.
Established technology for challenging conditions – suited for sites with challenging soils, high winds, and irregular terrain, IDEEMATEC’s safeTrack H4 trackers™ reduce the risk for Engineering, Procurement & Construction Companies by providing project developers and asset owners with the most value added over the entire lifetime of their power plant.
Highest Peak Power Ratio – the safeTrack H4™ flexible string configuration allows for a max. number of modules per tracker and requires only 1 Drive Unit for 360 Modules to provide support for up to 12x 1500-volt strings – currently the market benchmark. With only 0.5 pcs. SIGMA foundations per DC string, the high-span safeTrack H4™ reduces tracker installation costs by offering the least amount of posts at the lowest embedding depth.

TECHNOLOGICAL BENEFITS
MATERIAL
SAVING
The reduction in foundations and drives cuts BOS costs.
SCALEABLE
DESIGN
With no driving rods between rows, the rows can be planned on uneven terrain.
PLANNING CERTAINTY
Flexible planning without the need for earthworks reduces costs and risks.
.
VERSATILE APPLICATION
Crystalline, thin film, 2 rows in portrait, 4 and 7 rows in landscape, 1000 V/1500 V.
EFFECTIVE CONSTUCTION
Maximum stability and sturdiness with the minimum of materials.
PATENTED DRIVE
The core component of the safeTrack Horizon H4PLUS is the low-set load-decoupled drive unit, which is fitted down low. The low center of gravity gives the structure exceptional stability. The wire rope pulleys transfer 95% of the impacting forces past the drive unit and directly into the foundations. This results in a drastic reduction of the foundation number and drive units. Wear and material fatigue are reduced to a minimum.
AVAILABILITY
Proven system uptime availability of 99.5% since 2007.
WEAR-FREE
The load decoupled drive unit operates on a frictionless basis.
LOW-MAINTENANCE
The low number of drive units means minimum maintenance.
BARRIER-FREE
Unhindered access and passage between rows makes for easier cleaning.
PLANNABLE
Minimum effort involved in the provision and storage of spare parts.
THE MONITORING SYSTEM
The control and monitoring system with multiple redundancies is the perfect tool for streamlined and user-friendly plant management. IDEEMATEC’s proprietary KoRoNa software controls all drive units by means of an ultra-precise astronomical algorithm.

1
A dynamic SCADA system, which can be configured on a project-specific basis, facilitates efficient monitoring via a central control unit. The SCADA connection via TCP/IP and Modbus is ready-prepared in the control system.
2
“Unlinked tracking” without driving rods permits barrier-free maintenance. In case of a fault, only the affected row of tables comes to a “stop”, not the entire block as is the case with linked row trackers.
3
Snow cover, which reduces yields, is detected by the snow sensors. The tables are tilted up to 55°.
4
AC system: Power supply via the grid or diesel generator.
DC system for maximum reliability: With charging regulator and battery pack (standard batteries available from retailers).
MAINTENANCE BENEFITS
AC and DC
Monitoring system available as either an AC or a DC version.
REDUNDANT
Both systems (AC and DC) are designed with multiple redundancies.
FAILSAFE
Solar park internal cabling reduces the risk of default to a minimum.
BACKTRACKING
Shade-free backtracking immediately on commissioning.
QUICK
All trackers move to the security position at the same time.
BATTERY/DIESEL
Emergency power supply: DC via batteries; AC via diesel generator.
ALARM: SMS + E-MAIL
Alarms are sent immediately by SMS and e-mail.
SCADA CONNECTION
Prepared via Modbus and TCP/IP interfaces.
AT-A-GLANCE
Technical concept
- Tracking range of the tables +/- 55°
- Tracking without driving rods; allowing for individual row and terrain adaptable backtracking
- Wind tunnel tested. Maximum operating wind speed of 60 km/h; up to 290 km/h in the security position
- Suitable for all module types (glass-glass) and electrical systems (1000 V, 1500 V)
- Pre-assembled mounting units enable fast installation
Superior drive unit
- Patented, fully synchronous and torsion-free drive technology based on a steel cable system
- 0.1° accuracy over a drive length of 160 m
- Torsion-free drive unit: Ultra-low-wearing and fatigue-free drive units due to load-decoupled drive shafts
- Direct transmission of the acting forces (e.g. load, wind load) into the foundations via cable pull systems
- Dampening static effect and massive reduction in the wind load on the modules
- Low center of gravity, resulting in a low embedment depth for the foundations and widely spaced foundations
- Zero stress on the modules due to torsion-free module tables and prevention of micro-cracks and glass breakage
Maximum efficiency
- Lowest material and installation cost per Wp
- Highest terrain adaptability of all trackers on the market (gradients of up to 36%)
- Required foundation points reduced by approx. 60% (only 180 foundations per MWp)
- Minimization of earthworks and leveling works, even on highly undulating terrain
- For all types of soil from sandy to rocky ground
- Row length of up to 160 meters, with up to 8 tables tracked by a single drive unit
- Up to 60 percent less gearboxes and engines
- With an output of 112 kWp per drive unit, the best drive/performance ratio on the market
- Adaptive single row backtracking without row shading
- Fixed wiring and failsafe monitoring system with multiple redundancies
- Monitoring system available either as an AC version or a DC version with a battery pack
- Flexible string configuration
- Module layout with 2 rows in portrait or 4 rows in landscape (crystalline); 7 rows in landscape (thin film)
