100% target achievement by KECK for centrotherm

The SNEC PV Power Expo in Shanghai is not only the largest trade fair in the Asian photovoltaic industry, but also the most important globally. The technology provider Centrotherm took the opportunity to present highly efficient solar cell concepts and the associated production solutions to an international audience.

There were two extraordinary highlights:
The new centrotherm LPCVD production system c.DEPO LP, which ranks number five of the 25 most innovative production solutions for the photovoltaic industry. As well as the flexibilty app on the trade fair stand, which demonstrates the special variety of centrotherm production solutions to the public.

The KECK team faced two great challenges in the concept development stage. On the one hand, the aim was to surpass the great results from the 2017 event. On the other hand, the stand had to have an innovative design that was consistent with the highlights, and which could be realised at a very high standard despite the short set up and dismantling time.

The new trade fair stand design was characterised by the impressive façade made of large, blackened glass elements, in which the large-format (3 x 7 m) LED surface was integrated. Thanks to the two-storey structure, there was enough space to present the products in a way that would attract visitors, as well as enable in-depth discussions on the quieter upper level.

In the end, it was “mission accomplished” for KECK.

The fifth building material – Maintenance of ETFE constructions (maintenance des verrières gonflables en ETFE )

The ETFE is a modified copolymer which is extruded into a thin film. The material is ageing resistant, self-cleaning and transparent. It is unaffected by UV light, atmospheric pollution or weathering and extensive testing has shown an anticipated life expectancy in excess of 40 years (used e.g. for green house cladding). The material is self-extinguishing and it is resistant to normal hailstorms.

Single layer constructions are supported by a cable net. Cushions are formed from multiple layers of ETFE. The foil is extremely thin: each layer is between 50 and 300 µm thick, it enables very high levels of light transmission in both the visible (94-97%) and ultraviolet range (83-88%). Together with light weight perimeter frames it is easily possible to have buildings which appear like as they were built of not much more than air. Architectural roofing designs are revolutionized by these ETFE-films since many years now. Also greenhouses (horticultural and industrial) and wall coverings, anti-graffiti protection for high traffic areas and solar collectors are applications, ETFE is used for due to its excellent properties. ETFE has only 1% the weight of glass, is 100% recyclable and is self-extinguishing.

Despite these advantages of ETFE films there are some problems appearing according to the low thickness of the material. Usually cushions are stabilized by inflating with dry air. Especially on rooftops birds love to land there and peck at their food to break it up before swallowing. The bigger the bird the more powerful their pecking action will be. It is widely known that ETFE roofs and Canopies installed nearby or close to stages (e.g. Allianz Arena Munich) or the sea suffer most of this problem. This is because Ravens, Crows or Seagulls use the ETFE roof membranes as an ideal platform to stop and peck at food rubbish or shellfish, crabs and the occasional stolen chip. This often vigorous and powerful pecking action causes punctures and tearing to the ETFE Membrane, opening holes where the inflating air can leak. This causes higher operation cost or the possibility of fatal destruction of a complete cushion.

Fortunately the ETFE material is resistant to tear growth so that it is easy to repair such holes and tears on-site by using a special adhesive tape from CMC Klebetechnik. This transparent tape is made of the same material as the cushion itself: an 100µm ETFE-film. The adhesive sticks good to the cushion surface and is similar resistant to UV and weathering as the ETFE. It is resistant against creeping of water under the adhesive tape and elastic as the base material of the cushion.
This is why CMC 77700 ETFE adhesive tape is ideal for repairing of damages (minor tears or holes) or reinforcement e.g. under supporting cables of single layer constructions. No need to replace individual elements of a roofing construction can save a lot of money. And due to the transparency of the adhesive tape, repairs are nearly invisible. Maintenance with ETFE adhesive tapes from CMC Klebetechnik reduce costs, time and effort for repair.

Meyer Burger divests its Solar Systems business to Patrick Hofer-Noser

As part of the optimisation programme regarding the Thun manufacturing site and the company’s product portfolio which was communicated on 2 November 2017, Meyer Burger Technology Ltd (SIX Swiss Exchange: MBTN) announced today that it will transfer its Solar Systems business (“Energy Systems”) and the 32 impacted employees to 3S Solar Plus AG, a company which will be newly created and which has been sold to Dr Patrick Hofer-Noser. In the past few months Meyer Burger had evaluated various strategic options for the business which mainly addresses the Swiss market with its MegaSlate® products. The sale will result in a loss for Meyer Burger in the low single-digit million range including a goodwill recycling of around CHF 1 million. Completion of the contract which has been signed with Dr Patrick Hofer-Noser is subject to standard closing conditions and expected to be completed in the first half of 2018. Both parties have agreed to maintain confidentiality regarding the transaction price.

Hans Brändle, CEO of Meyer Burger: “By selling the Solar Systems unit to Patrick Hofer-Noser, we have found an industrial and especially also local solution for the MegaSlate® business and the employees.”

Patrick Hofer-Noser is a long-time, internationally respected specialist in the solar industry. He was a founding member and later Delegate of the Board of Directors and Chief Executive Officer of 3S Industries AG, in Lyss/Switzerland, which merged into Meyer Burger Group in 2010. Thereafter he was Chief Technology Officer and member of the Executive Board of Meyer Burger Group until 2012. From April 2012 until April 2017, Patrick Hofer-Noser was Head of Energy Systems and until he left Meyer Burger in December 2017 he held the position of Policy Liaison Officer.

Patrick Hofer-Noser: “Together with my employees and partners I look forward to further developing and expanding the market position of the aesthetic and reliable MegaSlate® solar roof and facade system which has been manufactured in Switzerland for more than 15 years and to making a contribution to protecting the climate.”
