The enormous ceremonial switch was thrown Tuesday at Walt Disney World for a 22-acre solar farm near Epcot Center that just happens to be shaped like Mickey Mouse's head.

As the Tampa Bay Times points out, the array actually began generating power last month, but nothing's really official until somebody flips that oversize switch.

Comprised of 48,000 solar panels, the Mickey Mouse project is part of a 15-year agreement that allows Duke Energy to build, own and operate the five-megawatt farm on Disney's land. In exchange, the company provides power to the theme park and other nearby businesses.

“As a company that cares about the environment, we continually take steps of varying sizes to benefit the environment and protect the planet,” Angie Renner, Disney World's environmental integration director, said in a statement. “This new solar facility will help us in our efforts to conserve natural resources.”

While, at 22 acres, this might seem like the largest "Hidden Mickey" -- that's the name for the iconic Mickey Mouse heads hidden around Disney properties -- the Orlando Sentinel says the solar farm falls a bit short: The biggest is actually a 60-acre forest in Clermont, Florida.
