Solar ♦ news digest of solar systems”


The FranzenGroup works in the field of open system curtain wall façades and has the necessary cross-discipline know-how to meet the challenge of integrating photovoltaics in building façades. With over 40 years in the façade business and long-term involvement in the solar sector, Franzen combines, under one roof, all the necessary skills for both aesthetic and functional installation and layout of fully integrated façade systems. Unnecessary interfaces with other trades are no longer applicable.


“Franzen combines, when it comes to the handling of our new types of solar components, a decisive, and until now rare, combination of skills, namely experience in façade construction and in the design of solar systems,” explains Hein van der Zeeuw, CEO of Odersun AG. “The constructional and artistic integration of solar in buildings can only be successful when the necessary systems and the decisive experience and competence in planning and installation are combined with suitable materials.”


The cooperation between Odersun and Franzen forms another important link in the chain between manufacturer, system supplier and planning and installation.


“As a classical installation company, we were one of the first businesses to turn to the integrated use of solar energy in buildings. It was clear to us that there was a dynamic movement toward the incorporation of new technologies for sustainable energy supply within the building, a movement for which we wanted to be prepared,” says Dipl.- Ing. Jürgen Krämer, a managing director at FranzenGroup.


“We have more than 40 years experience in installation and have been active in the solar sector since 2005. With the new components from Odersun, we can now combine both skills and offer solar façades, which also meet the requirements of aesthetic integration.”


PowerFLEX thin-film module is awarded IEC and UL certifications


The Most Efficient Flexible Solar Module


The flexible module PowerFLEX BIPV from Global Solar Energy, a provider of flexible thin-film solar cells based on CIGS technology, has been awarded the IEC 61730 and 61646 as well as UL 1703 certifications.


The flexible thin-film module fulfils the strict requirements of safety, reliability and durability set by two independent test laboratories, the International Electrotechnical Commission (IEC) and Underwriters Laboratories (UL).


Its low weight of just 3.5 kg/m2 of module area makes the PowerFLEX BIPV particularly suited for industrial flat roofs, which are often not strong enough to bear the weight of thick-film photovoltaic installations. With 12.6% efficiency in relation to the aperture area, the solar module is the most efficient flexible module in the market to date.


The successful certification confirms that the flexible thin-film modules from Global Solar Energy are able to guarantee safe electric and mechanical operation for the duration of their entire expected lifetime, and that they are suitable for permanent open-air use. They also meet the requirements of the Prototype Building Regulation (MBO) laid down by the Conference of Ministers of Construction, a working group for urban development, construction and housing of the responsible Ministers and Senators from the 16 German Federal States.


“The UL and IEC certifications represent another milestone in the rapid development of Global Solar Energy. We are already planning several installations in the US and Europe,” explains Jeff Britt, President and Chief Executive Officer of the US company with a German subsidiary in Berlin- Adlershof.


“Due to its high efficiency and low volume of materials, the new module can be offered at an extremely competitive price, which will help property owners to reach a quick return on their investment and achieve profitability.”
