Sigma II – Ground-mount PV System

Ground-mounted PV

Sigma II

The Lightweight, Easy-to-Install System for Cost-Optimized Use in Large Solar Parks

For large solar parks, our ground-mounted system Sigma II offers you an optimal cost-benefit ratio.

It covers with two to four modules in portrait the entire spectrum from optimum yield to maximum land utilization.

Various foundation solutions - Post, Ground screw or Concrete - enables adaptation to a wide range of soil conditions.

The integration of Cable routing, Inverter and DC collectors is a matter of course.

System configurations
- 2P/2V with high inclination, south-facing, for optimum yield or high snow loads
- 3P/3V with normal inclination for optimized power/yield balance
- 4P/4V with low angle of attack for maximum area yield
- All configurations are also available as an East-West System
Technical details
- Two-post rafter frame made of galvanized steel in several design variants as single-sided South frame, or
- double-sided East-West frame executed
- Up to 10° terrain slope along table
- Up to 45° terrain slope across table
- Up to 45° inclination with almost any ground clearance
- Split foundation profil for better handling,
- various foundation variants incl. ground screws, in-cast concrete or concrete slab
Design principles

We are happy to present our design principles to you in a transparent and comprehensible manner.

On the basis of the Eurocodes and especially its National Annexes we provide you with systems that meet the requirements of wind, snow and earthquake loads as well as air and soil corrosivity.

This enables us to provide a structural warranty for our systems for the entire planned operating lifetime.
Applications
- Ground-mount projects
- Agri PV
- Glass-glass modules
- Framed modules
- Bifacial modules
- Portrait
- Landscape
- 10-year Warranty
- 25 - 50 years Structural Warranty
PV modules

Depending on requirements, the system is suitable for both portrait (2-4 modules) and transverse mounting (4-5 modules).

With our Sigma II, all current PV modules can be reliably clamped or bolted in accordance with the module manufacturer's specifications.

The screw connection enables simple installation from below and direct electrical potential equalization.
Cable management and inverter holder

The integrated cable management concept enables simple, yet protected (UV and mechanical) laying of cables within the longitudinal rails of the system.

As an option, we offer the integration of string inverters or DC collectors within the Sigma II with or without bite protection.
