GEG AG completes façade project

Building integrated photovoltaic sets a new architectural trend

(PresseBox) (Teningen, ) The integration of photovoltaic modules into the vertical façade of a building opens up new possibilities to the solar industry. Since more and more clients want to move away from fossil fuels and consider an upgrade with renewable energy sources, new perspectives are especially interesting for architects. They have to respond to the increasing demand for integrated solar systems into building components and the construction process as a whole. GEG AG and Hans Eisele GmbH from Glatten recently completed the façade project of ARBURG GmbH in Loßburg.

There are many good examples for projects made from or with photovoltaic modules. Nonetheless, architects, project managers and builder-owners are not yet fully aware of the vast variety of possibilities in form and design. Especially for architects, energetic aspects have lately gained an overriding importance. Modern solar modules have turned into components that not only serve for generating energy but also as building cladding. "Photovoltaic enables us to a variety of creative designs, while at the same time producing emission-free energy and protecting the atmosphere", says Dietmar Gerber, founder and executive of GEG AG. To guarantee an ideal planning and implementation, it is necessary that architects and solar engineers work close together right from the start.

In cold façades, the modules function as external panelling, in warm façades they can substitute the outer layer completely. Given the right statical preconditions, a solar plant can be installed on or in almost every façade. Façade modules are not ready-made, but rather expensive and customised solutions.

However, they put into perspective the relatively high investment costs by autonomously generating earnings for many years. Researchers and the industry keep developing even more progressive and intelligent solutions for façade integrated modules, thereby giving hope for even more freedom of design and lower investment costs.

For technical and creative purposes, the involvement of a photovoltaic plant in the course of a new building or a reconstruction turns out to be the best solution, as the plant can be included in the planning process. If so, it is possible to consider a low priced normative module. A subsequent installation often brings about the application of a customised product.

GEG AG with its headquarters in Teningen in the south of Germany realised its latest façade project in cooperation with Hans Eisele GmbH from Glatten. The plant was installed on the south façade of a new customers centre that the manufacturer of injection moulding machines, ARBURG GmbH, is currently erecting at its headquarters in Loßburg. By the new glass-like modules, the company wanted to upgrade the extensive south façade technically as well as architecturally.

Overall, 144 customised modules of the type Solarwatt M 125-32 GEG LG 124 Wp opak were mounted. With a surface area of 162 square metres, they will generate a total output of 17,856 kWp. The used photovoltaic modules consist of laminated toughened safety glass with an embedded photovoltaic cell. By default, the back side is coated in black. The dimension of the each module is 1490 mm of width x 755 mm of height. In addition, the customised modules are 15 millimetres thick, complying with the structural preconditions and regulations for a point-to-point fixation at the fronts of high buildings. "When planning such a photovoltaic plant, you not only need to consider the electro-technical demands, the thermal reactions of the façade and the static of the building. In order to protect the façade effectively from humidity and for the modules to generate an optimal result, the aeration system is of mayor importance", explains Dietmar Gerber.

The scaled arrangement of the modules has the advantage that the modules are perfectly ventilated from all sides. Each module gets fresh air. As the modules are arranged in an angle of inclination between 88 and 89 degree, the sun can better act on the elements. As a result, the effectiveness of the whole plant can be strongly increased.

For the further solar electricity production, GEG AG chose four inverters of the type SMA Sunny Boy 3800, manufactured by SMA Technologie AG. The photovoltaic modules were fixed with the system AL-Wall by the company Längle Glas Befestigungssysteme, which made a drilling of the glass modules wholly unnecessary.


Founded in1997, GEG AG is today an established and renowned manufacturer and wholesale trader for renewable energy systems. With an own montage system, photovoltaic modules and solar heat collectors, GEG AG is able to react fast and accurately to the specific needs of its customers. Furthermore, the company is specialized in the consulting and project development of façade technologies. With the French subsidiary GEG Solaire France, GEG AG underscores its consistent growth and has lately begun to supply the international market.
