You won't be able to see them, but shiny solar panels are on top of Radiator Springs Racers.

The panels were installed beginning in August on top of the Disney California Adventure attraction's show building. They're now online, providing some electrical power to the theme park.

Matt Gray, the director of park operations at the Disneyland Resort said it was done to help deliver on a commitment of being environmentally friendly adding that it "contributes to our companywide goal of reducing use of electricity."

More than 1,400 panels were installed, the first time this has been done at the Disneyland Resort.

The sun-powered array covers 40,000 square feet, and provides the equivalent of enough electricity to power 100 homes in the Anaheim area.

Resort officials said that adding more solar panels to other buildings are not planned, but that plans could change.
