alwitra.The specialist for high-quality flat roof systems.

Flat roofs have become an integral part of modern architecture.

No wonder, because they offer far more possible usages than

any other roof form. Whether as a roof terrace or garden in urban

areas, as a semi-natural and climate-friendly green roof or as a

usable area for solar energy generation: The present belongs to

the flat roof – and so does the future.

Flat roofs offer ideal conditions for solar energy generation – you

just need to know the essentials.

With the proven alwitra flat roof systems you will benefit from

more than 55 years of experience in flat roofs. Drawing also on

20 years of know-how in solar technology, we provide you with

unique integrated solutions from a single source, ranging from

high-quality roof waterproofing to complete solar roofscapes.

Flat roof and solar technology:If there’s one thing we know, it‘s both.

We presented the world‘s first building-integrated solar installation as early as 1999:

EVALON® Solar – a waterproofing membrane for both waterproofing and power generation at the same time.

EVALON® solar waterproofing membranes generate PV output of almost 40 MWp on more than 2,000 roofs and actively contribute

to climate protection: Around 20 million kilograms of CO2 emissions are avoided every year.

EVALON® Solar cSi –The world‘s one and only solar waterproofing membrane.

20 years later alwitra presents its next multifunctional innovation:

EVALON® Solar cSi - the world‘s one and only waterproofing

membrane with integrated semi-flexible crystalline PV modules

without glass - made in Europe.

EVALON® Solar cSi stands for the unique integration of globally

available robust crystalline silicon solar cells into the proven

synthetic waterproofing membrane EVALON® by alwitra.

Thanks to the patented glass fibre reinforced duromer core,

EVALON® Solar cSi not only guarantees stability and durability:

The special design without glass allows for flexible installation

on undulating or curved roof areas.

EVALON® Solar cSi is a product for building-integrated photovoltaic installations. The system can

be used for both new build and refurbishment of flat slope roofs.

Thanks to its low net weight of 3.3 kg/m2 it is also predestined for use on roofs with low load

bearing reserves.

In the area of the PV modules, the roof surface must be free of ponding water. To avoid puddles, we

recommend a minimum roof slope of 3° or 5.2 %. Curves such as arched roofs can be formed up to

a radius of 2 m in the direction of the long side of the PV modules.

Fig. 1: PV installation with alwitra EVALON® Solar cSi solar waterproofing membranes incl. alwitra cable routing system accessory

Fig. 2: alwitra cable penetration “kerb incl. rooflight” for up to 8 solar cables; with optional extension sets for up to 8 solar cables each

Fig. 4: alwitra cable penetration “vapour barrier” for up to 8 solar cables

Fig. 3: alwitra cable penetration “roof waterproofing” with 4 factory integrated solar cables

The core of the building-integrated photovoltaic installation is

the multifunctional EVALON® Solar cSi waterproofing membrane

with ready-to-connect cables and Tyco Solarlok PV4-S solar plug

connectors.

In addition, we offer you a well thought-out accessory package

with a cable routing system including mounting base and cable

duct (Fig. 1).

Special cable penetrations in different versions for the water-

bearing level or the vapour barrier are available for routing the

solar cables through the roofing package:

• placed on the roof waterproofing (“kerb incl. rooflight”) for

up to 8 solar cables with optional extension sets for up to

8 solar cables each (Fig. 2)

• integrated in the roof waterproofing (“penetration collar” below

the cable duct) with 4 factory-integrated solar cables (Fig. 3)

• for airtight connection to the vapour barrier in the insulation

package for up to 8 solar cables (Fig. 4)

To turn your flat roof into a safe rooftop power plant, you need

not only high-quality products but also competent advice. At

alwitra you get both - and an optimal concept tailored to your

individual building project.

Already in the early planning phase you will benefit from the

comprehensive alwitra service in the form of extensive technical

advice by our expert consultants on site as well as support in the

form of project-specific, detailed installation plans and wiring

diagrams.

On request, our experienced technicians will be glad to advise

you on the installation and mounting of your building-integrated

PV system.

EVALON® Solar cSi –Flat roof and PV at work.

EVALON® Solar cSi waterproofing membranes are laid on flat

slope roofs as a single-layer roof waterproofing.

The solar waterproofing membranes are mechanically fixed to

the supporting substrate, with a longitudinal overlap.

The cable routing system is installed at the butt joints of the

EVALON® Solar cSi waterproofing membranes between the PV

connection boxes.
