PV facade on high-rise residential building

Colored Photovoltaics - SUNOVATION eFORM unichrome

Architectural harmony

A high-rise residential building in Regensburg has been modernized and equipped with a building-integrated photovoltaic facade from SUNOVATION. The facade and balconies are equipped with a BIPV facade integrated into the building envelope. This harmonizes perfectly with the other facade materials thanks to the special coloring of the glass-glass modules, which were manufactured in a project-specific champagne shade. The verdict of the db, the German building magazine, was that "the photovoltaic facade is a sign of a new beginning - but one that is integrated into the architecture with rare harmony".

Colored photovoltaic facade of sustainable office building


BIPV-Modules made in Germany

Power-generating SUNOVATION eFORM unichrome glass-glass modules in the colors slate and champagne form the building-integrated PV façade of this sustainable office building in Berlin, which was built using a timber hybrid construction method. On over 330 m², the 170 modules in 9 different module sizes provide an installed output of 47 kWp on the facade and thus contribute to the targeted DGNB Platinum certification. Thanks to the individual production of the photovoltaic elements, the colors of the BIPV modules were freely selected and the desired facade design could be precisely covered with the colored glass-glass modules. This pays off not only in the overall appearance of the facade, but also in the level of installed output. Pictures: S+T Facades


Convincing product features

The sustainably constructed, multi-storey building in Berlin is largely made of wood and sustainable materials. In addition to the customization options and first-class PV yields, another important feature of SUNOVATION eFORM modules comes into play here - with the best possible fire classification for PV modules, they also optimally meet the requirements for exterior wall cladding of buildings in building categories 4 and 5.

Renewable power generation with SUNOVATION eFORM clear

Solar energy at the charging station

This charging station provides customers with 100% green electricity. Individually manufactured SUNOVATION eFORM clear glass-glass modules are integrated into the oval roof of the charging station as overhead glazing. In addition to generating electricity, they also provide protection from the weather. The semi-transparent modules, in which the PV cells are visible, were individually configured to match the architecturally appealing overall appearance of the roofing.


In addition to the rectangular glass-glass modules, the oval sections of the roof are also covered with active modules in special shapes. Like the shape of the glass, the arrangement of the PV cells was customised to suit the shape of the canopy and the client's requirements. The client opted for a 50% PV coverage to achieve the desired level of transparency and special appearance.

Sustainable power generation at railroad station


Roofing with added value

The expansion of renewable energies at railway stations in Austria continues. At Telfs-Pfaffenhofen station, a platform roofing with transparent SUNOVATION eFORM clear triple glazing modules has been installed. Covering an area of 844 m², the photovoltaic roof protects train passengers from the weather while generating around 108 MWh of electricity. The glass-glass modules are designed to withstand the increased wind loads associated with train operations, and their special construction provides an enhanced level of safety, resistance to vandalism, breakage and falling through. To ensure the safe operation of the PV system in the immediate vicinity of high-voltage lines, SUNOVATION also drew on its many years of experience in the design of electrical PV generators.

Transparency and safety

The 330 translucent SUNOVATION eFORM clear glass modules in five different sizes are designed as VSG glass modules with a translucent interlayer combination specially selected according to customer requirements. As a result, the shadows created by the modules appear homogeneous and are not dominated by the integrated PV cells. This reduces visual irritation on the platform and increases safety and walkability. A structural glass roofing system was used to secure the photovoltaic modules, with the glass-glass modules mounted linearly on two sides. The triple structure of the glass-glass-modules allows safe access to the modules for cleaning purposes.

Solar Decathlon Europe 2021/2022

SUNOVATION sponsors three teams

Team Level Up from Rosenheim

Team Level Up's focus in the competition was on adaptable, modular and flexible residential extensions in timber construction. Building-integrated photovoltaics were used in the roof and facade area. A modern photovoltaic facade in light gray tones simultaneously generates electricity and with the help of a facade heating system, also provides the building's basic temperature control. The SUNOVATION eFORM unichrome modules installed in the facade and the semi-transparent glass-glass modules in the roof were sponsored and individually manufactured by module manufacturer SUNOVATION.

Team MIMO from Düsseldorf

Team MIMO developed a concept for resource-efficient redensification at SDE 21/22 according to their claim 'MINIMAL IMPACT - MAXIMUM OUTPUT (MIMO)'. At the final in Wuppertal, they presented an excerpt of their design concept in the form of two stacked compact solid wood residential modules. An intelligently controlled triple insulated glazed climate envelope made of movable glass lamellas with integrated photovoltaics forms the outer skin of the living elements. The individually dimensioned photovoltaic modules SUNOVATION eFORM clear for the solar facade and solar roofing were sponsored by module manufacturer SUNOVATION.


Team Local+ from Aachen

Team Local+ competed at SDE 21/22 with the vision "Local+ is more than just housing - we bring movement into your life". Their concept for a sustainable plus-energy house is based on movable room units/cubes, which can be used to combine private and communal spaces in the model house according to individual needs. In addition to a living facade, the model house features a PV facade on the south side. The curtain-type ventilated facade consists of green SUNOVATION eFORM unichrome modules, which were slightly modified especially for Local+ to visibly communicate the PV technology.

Sustainability, energy efficiency and design

18 teams from eleven countries have taken up the challenge of improving tomorrow's housing and living in the Solar Decathlon 2021/2022. The focus of the competition lies on future-oriented, sustainable urban development. The teams develope specific solutions and innovative redensification concepts for existing buildings and climate-neutral neighborhoods. Therefore they deal with questions such as energy efficiency, climate neutrality, mobile and social networking in an urban context and feasibility.

Congratulations to all the SDE 2021/2022 teams on their outstanding achievements!

High-performance, curved photovoltaic facade

Modern renovation of a building

Old building in need of renovation

The Marburg Medical Care Center has an enormous power consumption due to the use of special diagnostic equipment. Therefore, in the course of modernizing the existing building, a power-generating photovoltaic façade was used to produce sustainable energy. Architect Hagen Plaehn cleverly transformed the multi-story building into a modern yet functional, sustainable structure. Photos: © Christian Quast, Sonneninititative e.V.


Special architecture with seamless building-integrated photovoltaics

The photovoltaic façade consists of individually manufactured, frameless glass-glass modules SUNOVATION eFORM color. In order to meet the special features of the existing building, modules and substructure are custom-made. The glazed facade rounding of the building, as well as the rest of the facade, is equipped with active photovoltaic modules. For this purpose, curved glass-glass modules of 2 to 3 m² each were manufactured in five different heights and a radius of 2.5 meter.


Key technical data

BIPV facade 317 m²
Glass-glass-modules SUNOVATION eFORM color HPB 161 pcs.

The black photovoltaic facade is designed as a ventilated curtain wall. SG frames are attached to the back of the glass-glass modules for easy hooking into the substructure. For the curved glass-glass modules, precisely fitting curved SG frames were manufactured and glued to the curved elements. The result is an actively power-generating edgeless rounded photovoltaic facade. This construction method is made possible by the special production process SCET (SUNOVATION Cell Embedding Technology). Here, the module composite is produced by means of a cold filling process, which enables stress-free embedding of the photovoltaic cells in curved glass.


Roofing of a railroad station with transparent glass-glass-modules

Sustainable energy production in Vienna

Transparent canopy with integrated photovoltaics

The newly built canopy at Matzleinsdorfer Platz in Vienna is equipped with building-integrated glass-glass modules mady by the German manufacturer SUNOVATION. The expert for building-integrated photovoltaics produced 163 transparent photovoltaic modules in 24 individual shapes and sizes and individually adapted the transparency level within the modules. The multifunctional photovoltaic canopy aesthetically provides protection while generating electricity at the point of consumption.


Customized photovoltaic canopy

The 467 m² building-integrated photovoltaic canopy of the railroad station visually consists of two elements. Narrower areas are covered by cantilevered wing roofs, the wider areas by a construction with integrated photovoltaic skylights. For visual reasons and to increase the energy yield, the modules of the cantilevered roof structure are equipped with bifacial PV cells. The PV cells of the skylight modules were individually arranged: An adjusted spacing of the cells in the areas visible from below visually creates the illusion of a module limited to this space. In the area of the staircase, the cell spacing and thus the degree of transparency were increased in favor of a higher incidence of light. The glass structure of the modules was configured according to static and external requirements at the project site - the overhead glazing is made of laminated safety glass, is walkable and easy to clean.

It connects different parts of the building and is flooded with light through round ceiling openings that provide a view of the translucent BIPV roofing. Photos: © Atelier Altenkirch


Individual degree of transparency with maximum performance

The 420 m² building-integrated solar roof is configured with a transparency level of 50%. Due to its high-performance crystalline solar cells, the BIPV system achieves an installed power of 39 kWp despite this high degree of transparency, SUNOVATION's special silicone encapsulation process (SCET - SUNOVATION Cell Embedding Technology) enables the direct integration of diodes and electrical connections into the module composite to maximize PV performance. This allows power losses due to partial shading to be reduced and module surfaces to be used more efficiently. As with all transparent modules made by SUNOVATION, the edge connector „Connect 7“ was used for an invisible electrical interconnection of the glass-glass modules. Visually, the modules are completed by a discreet edge printing.

Curved facade elements

Adaptive design to achieve maximum integration

Futuristic Design

The new office building designed by the Architekturwerkstatt Vallentin was implemented according to the passive-plus-energy house standard. It excels through its futuristic design and the combination of down-to-earth and innovative materials. One remarkable design element are the striking, individually designed photovoltaic facade elements, which have been attached to the railings of the floating corridor.

Sophisticated details

One particular feature of the semi transparent BIPV modules is the finishing of the rear side of the modules by means of selective screen-print. By imitating the front cell optics, the module surface visible from the inside ideally integrates itself into the design concept. The highlight, however, are the two curved photovoltaic elements on the curved structure of the triangular shaped atrium. The approximately 3m² large glass-glass modules are bent in a radius of approximately 3.5m. By means of their adaptive design, they perfectly harmonize with the building line and optimally blend into the overall design.

The electric cabling of the PV facade glass was installed horizontally within the frame construction. 

Exclusive gas station roofing

Transparent and roof-integrated

Gas station of the future

The initiator of this project, an ecologically committed operator of a major gas station chain, aimed to transfer the subject of environmental consciousness into the market for fossil energy. The assignment here was to design an exclusive, design-oriented roofing solution with integrated photovoltaic.

Transparence, protection and communication

Project-specifically manufactured glass-glass elements have been installed as an integrated roof on different stations. Due to the transparent appearance of the solar modules, open, light-flooded, yet protected areas have been created to place the design element of photovoltaic into center stage. The ideas „renewable energy“ and „climate protection“ have been integrated and communicated into the world of gas stations in an intelligent way.

The planning of the electrical wiring of the PV glass elements was carried out by SUNOVATION.

Black design facade

Elegant appearance with added value

Homogenous and straight

The building developer of this special object had a precious, homogenous looking glass facade with the special something in his mind. The focus of the conceptual planning was the uniform black appearance of the facade that serves to accentuate the clear lines of the building.

Glass-glass modules instead of thin-film

Initially planned with thin-film modules, this facade was realized with glass-glass modules. These do not only offer the requested homogenous dark surface, but due to the crystalline solar cells also generate a higher yield. On top of that came the adaptability of the facade elements to the special requirements of the specific architecture of the building. For this project a total of 330 photovoltaic and décor facade elements with approx. 20 different dimensions were individually produced and installed.

Multi-functional facade of an office building

Insulating glazing with additional benefit

Straight and rich in contrast

The building developer of this project is a specialist for building envelopes and planned a solution which meets his ideas for the design. The goal was to design an insulating glazing with integrated photovoltaic, which adequately picks up the straight, design-oriented style of the metal facade.

Building envelope with additional value

The special character of this insulating glazing with integrated photovoltaic reveals itself to the viewer particularly in the inside of the building. There the visible solar cells are responsible for the specific shadow play and hint at the idea of subject sustainability. By means of the partial shading an overheating of the interior space is avoided. The 2-fold insulating glass ensures the necessary thermal insulation, while the monocrystalline high-performance cells create electrical power.

Industry facade of a different kind

Glass-glass modules with integrated LED lighting

Modern industrial building

The simple industrial facade was supposed to innovatively represent sustainability. A unique solution was developed to add value to the industrial building in a modest but effective way.

Spectacular distant effect

During the day this glass facade is impressive due to its photovoltaic cells. However, the integrated LED lighting is the highlight of the construction. At night the facade is illuminated with bright light and thus impresses with a spectacular distant effect.
