General Motors (NYSE: GM) has installed an 8.15 MW solar array on the rooftop of one of its Adam Opel AG plants in Rüsselsheim, Germany.

The array is one of the largest installations in Europe with an area equivalent to 32 soccer fields and will produce up to 7.3 million kWH of energy annually, reports Triple Pundit.

The array will reduce the plant’s CO2 emissions by about 3,150 tons each year.

Together with GM’s other solar arrays in Kaiserslautern, Germany, and Zaragoza, Spain, this array will allow the company to produce 19.1 million kWh of electricity a year, the equivalent to the avoidance of 8,200 tons of CO2 emissions–the same amount needed to supply 5,800 household with their annual electricity needs.

While solar electricity produced at Rüsselsheim feeds directly into the grid of the plant and is used in vehicle production, the excess

solar power is fed into the public grid of German energy company Stadtwerke Mainz and hence to Rüsselsheim itself.

Originally aiming to reach 60 MW by 2015, GM’s new goal is to increase its renewable power target to 125 MW by 2020.

Mike Robinson, GM vice president, Sustainability and Global Regulatory Affairs. “It is because of this type of progress that we are committed to increasing renewable energy use to 125 MW by 2020…The projects we undertake in Europe are great examples of the way we roll sustainable practices into our manufacturing process. We seek out renewable energy opportunities around the world to help clean the grid, improve our bottom line, and reduce our impact on the environment.”
