It's getting at least 10% of its 20MW from the first of 2 solar sites. Apple's Maiden County site is designed to use about 20MW of total power: http://news.cnet.com/8301-11386_3-57415501-76/apple-slaps-back-at-greenpeace-for-dirty-cloud-report/ http://news.cnet.com/8301-11386_3-57415501-76/apple-slaps-ba... They currently source 60% of that onsite (the rest of their power is sourced through the grid). http://www.apple.com/environment/renewable-energy/ http://www.apple.com/environment/renewable-energy/ What do they have onsite? 10MW of fuel-cell power and a 20MW solar plant. That means that even if the fuel cells are running non-stop at capacity, they're sourcing at least 10% from the first of their two solar sites (the second will be operational later this year). At 2MW, that would have the solar cells operating at 10% capacity factor. Typical capacity factor for solar cell installations is 20% so the actual contribution from solar is likely closer to 15-20% of the data center's total power.
