Innovative sustainable building facades become efficient solar energy harvesters

Building Envelopes Powered by HeliaFilm® and HeliaSol®

The demand for PV solutions in new building and refurbishment projects, and the energy optimization of existing buildings, is growing worldwide. Façades of industrial and commercial buildings offers mostly still unused surface areas for generating power. Inventory roofs, where up to now a PV installation wasn´t allowed, can be turned into power houses while using the solar films from Heliatek. HeliaFilm® and HeliaSol® offer a unique solution for building integrated organic photovoltaic installations (BIOPV).

Ultra-light, thin and flexible

Heliatek´s solar films can be directly applied to façades or roofs or integrated into building materials, while no extra cooling or ventilation system is needed. Generate power with your façade and take one step towards independence from the centralized power supply!

Energizing existing buildings with HeliaSol®

The “ready-to-use” film solution HeliaSol® can directly applied onto existing roof surfaces. HeliaSol® is suitable for all energy-saving refurbishment projects where restrictions on weight, statics, insulation or penetration of the roof play a role in product selection.

Convince yourself and have a look at the quick and easy installation of our solar film:

Powerhouse with flyweight

Where standard PV technology is too heavy, HeliaSol® can be employed.

HeliaFilm® is enabling active building elements

Glass, concrete, aluminum, steel, foil, polymer sheets or PVC membranes -  Thanks to its thin design of less than 1 mm, HeliaFilm® can be applied with many different building materials. Heliatek is working together with industry partners to integrate HeliaFilm® into façade or roof elements to create a solar active building envelope. In, on or between, there are many applications in the areas of building integrated organic photovoltaic (BIOPV) for our solar films.

Energy producing façade will pay off

Compared to conventional solar technology on the roof, building façades usually offer a larger surface to generate solar energy. Depending on the location, the different orientations and possible shading, the power generation of your building can be optimized.

Industrial buildings get green

Improve your CO2 balance with HeliaFilm® and HeliaSol® and generate green energy with your building envelope.

A less-than perfect location is perfect for us: Superior energy harvesting behavior

Its excellent high temperature stability makes HeliaFilm® and HeliaSol® the material of choice for a number of BIPV applications. The harvested power remains strong even under less-than-ideal mounting conditions that often occur in BIPV applications. 

Ultra-light solar energy

HeliaSol® is the ideal solution for lightweight structures like air domes.

Only a normal façade?

Building façades get more and more multi-functional. They not only are the skin of a building and follow aesthetic requirements, but they now include additional features such as active sun protection, smart ventilation systems or distributed power generation. These sensors and components can be operated by the electricity generated by HeliaFilm®.


Urban fit: Seamless integration into architecture

The transparent version of HeliaFilm® can be applied to almost any glass façade and maintain its aesthetic appeal.

Transparency and power generation

Transparent solar films will open up new potential applications. Fully glazed office buildings will get a sun blocking function and deliver energy simultaneously. Architectural glass panels and windows incorporating HeliaFilm® enable electricity generation by the outside envelope of a building. The balance between light transmission and electricity generated can be adjusted to suit the application.
