The large roof areas of factories and production plants are an obvious choice for the installation of solar cells and Audi has just announced it will install additional photovoltaic modules on a 7,500 square meter (80,729 sq. ft.) area of the roof of its main plant in Ingolstadt, Germany. The expanded solar capacity will be used to charge the batteries of Audi’s e-tron models using new electric car charging stations and will also be used to provide green electricity to the plants’ production facilities.
The Ingolstadt plant already boasts 11,600 square meters (124,862 sq. ft.) of photovoltaic modules, which were installed in 2009. The additional 7,500 square meters of solar cells, which will be installed by the end of the year, will provide a peak output rating of 500 kilowatts with approximately 460 MWh of electricity obtainable from the new installation – enough to satisfy the needs of around 180 households.
