What a difference only a month and a half makes!

Back in early August, we saw the first photos of Apple’s new 171-acre solar array (capable of generating 84 million kWh of energy annually). It was impressive then – but these new shots courtesy of North Carolina’s TV Station WCNC-TV and GigaOm – show just how expansive the farm is growing.

When finished sometime later this year, the array (along with a 4.8 megawatts biogas fuel cell plant from of Bloom Energy) will supply some 60% of the power consumed by the data center. Another 40% will reportedly be sourced from renewable sources, such as wind.

Jump over to GigaOm for some additional closeup shots of the new array.
