If 6.3 kilowatts sounds like a lot of energy, it isn't. The average home consumes 27 kilowatts of power each day. Far more than the 6.3 kilowatts that will be produced by the new solar panels adorning the White House. According to TradeWind Energy, "one 50-watt light bulb running for 20 hours will use one kilowatt-hour of electricity (50 watts x 20 hours = 1,000 watt-hours = 1 kWh)."

In other words, the White House installed enough solar panels to power six 50-watt bulbs for 20 hours each day. And if you've ever been inside the White House, or seen it from a distance, you'll notice it's lit up like a klieg light. Excerpted from Boston.com:

You are mixing up units, comparing 6.3 kilowatts (the maximum panel output) to kilowatt-hours (power X time). A 6.3 kilowatt set of solar panels in Washington DC, according to this solar calculator, generates an average of 28 kilowatt-hours per day.

28 kWh is enough to run 127 11-watt LED light bulbs (60-watt incandescent equivalent 800 lumen output) 20 hours per day.
