DAS Energy Technology

Revolutionized photovoltaic innovations through research & development 

The patented technology used in our modules was developed by DAS Energy in Austria, and consists primarily of a proprietary fibreglass reinforced plastic core (pre-preg). This layer is found above and below the cell, and is primarily responsible for the flexibility and stability of the DAS modules. The material ensures that the photovoltaic modules are significantly lighter, thinner and more flexible than traditional PV panels. At just 3.8 kg/m2, they are much lighter than traditional heavy glass panels, and their flexibility allows them to fit the contours of curved surfaces. Our photovoltaic modules are non-reflective, as they do not use any glass. Traditional monocrystalline cells are used in the panels.

Our products offer high energy output while being ultra-lightweight and flexible. They weigh just 3.3 kg/m2  and therefore vastly reduce the requirements for substructures. The modules' flexibility means that they can be mounted in a variety of ways: on all types of roofs including waterproof membranes, metal roofs and many other types of roofing. In particular, DAS Energy modules can simply be glued to the roof, as well as being affixed using screws, rivets, magnets or grommets.


40 Years Performance Guaranteed

Our first certified PV modules have been in use since 2014 without issues. As the fibreglass materials used by us come from the aerospace industry and have withstood enormous wear in that capacity, we offer a 40-year performance guarantee for building-integrated and building-applied modules (85%). Our modules have been tested in numerous environments (UV resistance, climatic chamber etc.).


Monocrystalline cells

DAS Energy uses monocrystalline cells, the most commonly used photovoltaic cells. These cells are composed of perfect silicon monocrystals and offer particularly high efficiency, with over 22% of the light hitting the cell converted into electricity.

Our standard PV modules have a bend radius of 200cm. For specialised applications on rounded surfaces, we offer a specialised module structure (less and thinner fibreglass weave) that allows a bend radius of 15cm.

Patented prepreg method

DAS Energy's PV modules are made from fibreglass-reinforced plastic and the patented pre-grep material (chemically treated fibreglass weave). The development of this technology took six years and is a result of over 25 years of experience with fibreglass materials at Diamond Aircraft.

Custom-tailored photovoltaics

The shape, design and colour of the ultra-lightweight, flexible and durable DAS Energy PV modules can be customised. We offer modules ranging from 6 x 1 cells to 11 x 6 cells. Our production facilities can produce laminates of up to 4.9 x 2.0 metres in size.

Customized coloured cells

We offer coloured cells on demand, with various colours such as gold, red, green, brown etc. available in our modules. The laminate can also be coloured – while grey and white are used by default, other colours are available on demand.
