The site says Apple planned to have the facility up and running by February and it may be partially active as work continues. It also published a series of images showing the exterior of the building, though they are not particularly revealing. The building was built by a solar panel manufacturer but never saw production.
Rumors floating around the local electrical industry in Arizona claim Apple may be mulling a project expansion into a building on the site that was previously owned by photovoltaic panel maker First Solar. The purpose of the support structure is unknown.Apple originally announced the 700-employee manufacturing facility, in partnership with sapphire-maker GT Advanced, back in November. Tim Cook said in an interview that the facility would be making sapphire for a "secret project" with other reports saying the plant will see full production beginning in the second half of 2014.
