When constructing a new production site in Iggensbach (Bavaria), the company Fenecon planned a large facade solar system for power generation. For the secure mounting of the photovoltaic modules, planners and executors relied on a facade system from fischer BWM Fassadensysteme, which was further developed in cooperation with the module manufacturer Solarwatt to meet the project-specific requirements.
Fenecon is a leading manufacturer of energy storage solutions and offers systems for private households as well as for commerce, industry, energy suppliers, and vehicle manufacturers. The solutions use the in-house energy management system FEMS based on OpenEMS. Since 2017, the company Fenecon, based in Deggendorf in Lower Bavaria, has been producing large container storage units made from electric vehicle batteries. The success of the concept quickly made an expansion of production necessary. At the beginning of this year, the company put the new site in Iggensbach, located about 30 kilometers northwest of Passau, into operation: the CarBatteryReFactory. In the future, energy storage units made from zero-, first-, and second-life vehicle batteries will be manufactured there. The complex includes not only the production facility but also warehouses, development laboratories, and offices. The CarBatteryReFactory marks an important step towards the industrialization and mass production of large storage units based on electric vehicle batteries.
Fenecon planned to generate a large part of the energy for the new plant from renewable sources. Therefore, suitable roof and facade areas were planned to be used for solar power production. The photovoltaic modules were to be integrated into the ventilated curtain facade. "The advantage over roof and rooftop systems is that the winter yield of a solar facade is higher, and the electricity output is significantly improved even in the otherwise less productive months," says Benjamin Orths, who co-managed the project as International Product Manager for facade systems at the fischer Group.
The facade work was commissioned to Gaass Florian GmbH from Grainet, Lower Bavaria. Solar modules from our partner Solarwatt in Dresden were used. In total, 552 glass-glass solar modules of the type Solarwatt vision GM 3.0 construct were installed on an area of approximately 1,050 square meters. They deliver a peak power of 204.24 kilowatt peak (kWp). The solar modules have a general construction approval (abZ), which allows them to be used without additional safeguards for solar parking lot monitoring and for facades.
fischer BWM facade systems supported the project managers in the facade planning and jointly developed a project-specific fastening solution in partnership with Solarwatt, which can be transferred to other projects. "The result is a completely safe system that can be used in all relevant areas such as residential, office, and commercial construction, provided there is an anchoring substrate," says Benjamin Orths. "With our substructure for PV systems, already sealed surfaces can thus be utilized and existing facades activated to generate renewable energy."
The special feature of the innovative design: for the construction of high-quality architectural facades, visible disturbing components such as insertion rails and clamps can be omitted through fastening with clips. In addition, the system allows for a facade appearance with minimal joints. At the same time, it is a stress-free, permanent construction that securely holds the modules in the facade. The system can be easily and user-friendly installed and, if necessary, also dismantled.
