Flexible Solar Approval For PowerFLEX

The flexible module PowerFLEX BIPV from Global Solar Energy, a producer of flexible thin-film solar cells based on Copper Indium Gallium diSelenide (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 kilograms per square meter 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 Dr. 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.”

  

The PowerFLEX module is rolled onto and adhered to the roof membrane, requiring no mounting hardware. The roof membrane is not perforated, and no additional wind load is created. The look of the building is not altered. The PowerFLEX module has a large format (5.75m x 0.5m) and a high power density (300W). It is around 50% more efficient than flexible silicone solar cells.
