Seth Weintraub:

Today’s updated Apple Headquarters Spaceship campus plans include a roof made almost entirely out of solar cells, according to plans released today. With a building as large as Apple’s, that puts it in the top corporate solar installations in the world and the biggest in the US. The current title holder is the 4.26 MW system in Edison New Jersey.

This is pretty incredible. Seems like one of those details that is totally Apple.
