1 Introduction
The LEICHTmount 2.1 E/W system for flat roofs is an aerodynamic frame system that enables installation of photovoltaic
(PV) modules without roof penetration. It contains prefabricated aluminium brackets with attached building protection
mats (PES fleece, plasticizer-free) and all necessary small parts to ensure easy and safe installation.
The LEICHTmount 2.1 E/W is designed for the installation of systems with an east/west orientation and a pitch angle
of 10°. The system is configured for transverse module installation. It can be used for almost all commercially available
modules with the following dimensions: module width 950 – 1050 mm; module length 1559 – 1993 mm.
All components are made of aluminium and stainless steel. Their high degree of corrosion resistance ensures a long
service life and offers the possibility of complete recycling.
1.1 Intended use
The LEICHTmount 2.1 E/W system for flat roofs is an aerodynamic frame system that enables installation of
PV modules without roof penetration. It is designed exclusively for the installation of PV modules.
The LEICHTmount 2.1 E/W system is designed for easy installation on the following standard industrial roof coverings:
foil, bitumen, gravel, green, concrete.
Any use that deviates from this is classified as not intended. In particular, compliance with the specifications of this
installation guide is part of the intended use.
An important part of this installation guide is the supplied project report, which includes a site-specific
structural analysis. The design and planning of the LEICHTmount 2.1 E/W must be carried out using the S:FLEX
software (Solar.Pro.Tool).
S:FLEX GmbH accepts no liability for damage resulting from non-observance of the installation guide or from
misuse or incorrect use of the product.
1.2 About this document
This installation guide describes the installation process for the LEICHTmount 2.1 E/W system on flat roofs.
The LEICHTmount 2.1 E/W system includes suitable solutions for different load zones.
– LEICHTmount 2.1 Standard Version for maximum design loads of 2.4 kN/m²
– LEICHTmount 2.1 Alpine Version for maximum design loads of 4.4 kN/m²
This document shows the installation recommendations for:
– LEICHTmount 2.1 E/W with framed PV modules mounted transversely
– LEICHTmount 2.1 E/W Alpine with framed PV modules mounted transversely
It must be ensured that only current and complete installation guides are used for the installation process.
