Bürstadt photovoltaic system
At the time of its construction, the world's largest photovoltaic roof system was put into operation in 2005 on the building of a logistics company in Bürstadt (Hesse). The photovoltaic system is operated by the Sonnenfleck-TTS-Bürstadt project group and has a nominal output of 5 MWp .
Technology and performance
The facility covers an area of 45,000 m². That is roughly the size of eight soccer fields. Photovoltaic modules from BP Solar were selected for the construction . They have a microscopic pyramid structure on the surface, which is supposed to improve the absorption of diffuse sunlight.
It can generate around 4.5 GWh of electrical energy per year. This annual amount corresponds to the amount of electricity (kWh) that the nearby Biblis nuclear power plant generated in about 2 hours. This in turn corresponds to the consumption of around 1,200 private households and thus a share of 9 percent of the electricity consumption of the city of Bürstadt (15,000 inhabitants). The power is fed into the public grid via a total of three inverters .
History and location
The search for a suitable location for a high-performance photovoltaic system was supported by the Bürstadt municipality from the start. After a detailed examination, the buildings of the logistics company TTS with their large shed roofs turned out to be the ideal location. The license agreement was signed on April 2, 2003. The Sonnenfleck-tts-Bürstadt project group began building the facility. The investment volume of 23 million euros was acquired from a total of 10 banks. The system was built in four construction phases within 20 months.
Fire incident
On Sunday, June 28th, 2009, parts of the facility caught fire. Production errors in the solar modules manufactured by BP Solar were cited as the cause. However, only about 80 m² of the photovoltaic system on the 50,000 m² company roof were destroyed. The building itself was only slightly damaged.
In December 2009, BP Solar and Tauber-Solar Management GmbH announced that they had signed a joint agreement. This includes the reconstruction of all four construction phases of the "sunspot" solar system as well as changes to the system design and the installation. The system has since been dismantled, the solar elements were checked individually and rebuilt.
meaning
In addition to the production of solar power, the system has a high signal character for the economic use of photovoltaics. It makes it clear that high-performance large-scale solar systems can be built without additional landscape consumption and can also be operated economically at locations in Central Europe.
