Obama said in 2010 that he would retrofit his family's new home with solar panels starting in 2011, then use the power generated to heat water for the first family and provide some electricity.

Citing security and other concerns, the White House won't say how many panels now encase the top of 1600 Pennsylvania Ave. or how much they cost.
The panels are expected to generate 6.3 kilowatts of solar power whenever the sun shines, the White House said.

"Solar panels at the White House are a really important message that solar is here, we are doing it, we can do a lot more," Energy Secretary Ernest Moniz said in a video released by the White House.
The project required technicians to first drill down to the concrete on the White House roof, then use epoxy glue and threaded rods to install a gridded subassembly onto which the solar panels could be secured.
