3S Photovoltaics, a member of the Meyer Burger Technology Group [ticker: MBTN], has supplied the solar modules which have been installed on the roof of the Arena Thun. The frameless roof system guarantees high yields of solar-generated electricity with a reduced payback time.
For the stadium project in Thun, the experts for highly efficient building integrated solar systems in Lyss used a new type of modular system, characterised by its strong yield (nominal yield 245 Wp per module). The new 3S Photovoltaics concept reduces the solar module to its core functions. It dispenses, for example, with the aluminium frame for the module. Designed with ultra-robust cover glass, the module has an optimal load capacity. “In developing the module, we worked on the principle of reducing its construction to the core requirements for solar power generation”, says Christian Renken, Head of 3S Photovoltaics. “We also take this approach with smaller systems,” he adds, “and this year we will be launching a product for home owners who want to produce solar power using a roof system.” The absence of a frame prevents dirt from building up on the edges of the modules and thus ensures long-term, maximum energy production. Moreover, the payback time is shortened thanks to the sparse use of aluminium.
The new football stadium is not only one of the most modern sports arenas in Switzerland; it also has one of the largest photovoltaic installations in the Bernese Oberland. With around 1,700 solar modules, the roof area of the stadium will produce approximately 360,000kWh of solar power per year beginning this September. This is equivalent to the annual electricity consumption of around 80 households.
The new system is being installed by Bernhard Polybau AG, contracted by the newly established company Thun Solar AG. The energy produced will be purchased by Energie Wasser Bern and Energie Thun.
