Centrosolar introduces its new, ultralight mounting system for flat roofs at the Intersolar trade fair

Hamburg (ots) - Sleek and lightweight: Centrosolar presents a new,
aerodynamic flat roof mounting system for photovoltaic modules at the
Intersolar trade fair. This system enables photovoltaic systems to be
installed on flat roofs with minimum weight load and without damaging
the roof cladding. Intersolar Europe will take place from the 8th to
the 10th of June 2011 in Munich (Germany) and is the leading trade
fair for the solar industry in Europe.

The new Centrosolar mounting system is the ideal solution for flat
roofs, which are capable of supporting only a small additional weight
load for a photovoltaic system. Depending on the location, the system
has a weight per unit area of less than 10 kilograms per square meter
and is thus significantly lighter than conventional mounting systems.
It can be installed on all flat foil roofs at an angle of up to three
degrees, without damaging the roof cladding in the process.

A unique feature of the system is its clever mounting technique:
The substructure is mounted on the roof by means of a combination of
ballasting and welding with the roof membrane. As part of this
process, the welding absorbs the horizontal wind pressure. This
significantly reduces the ballasting required, which only has to
absorb the vertical wind pressure. A weight per unit area of well
below 10 kilograms per square meter can be achieved without
compromising stability. If friction welding is not possible, for
example, in the case of aged foils or bitumen roofs, ballasting alone
can be used.

The substructure of the systems is made of 100% polypropylene (PP)
and is shaped like an elongated triangle: The lower side rests on the
roof and the upper side is elevated at an angle of 15 degrees. A wind
deflector on the rear side seals the system and reduces the suction
force of the wind on the system. The module is mounted with
horizontally placed mounting bars. Longitudinal connectors are not
required for the installation to ensure that rain water can drain
freely. The row spacing can be adjusted by removing row connectors.
This also simplifies the integration on roofs with existing
superstructures or lightning protection systems. All Centrosolar
crystalline modules, as well as conventional module types of other
manufacturers, can be installed with the new mounting system.
