The panels will be installed gradually. First, the corporate building and the vehicle storage yard will get them, but the plan is to extend them over the production lines, covering up to 206,000 m2.
Not far away, in El Prat de Llobregat, is where Nissan installed solar panels as well. The Spanish government is currently giving subventions to big industries for such installations, where large surfaces are available.
