Solar Billboard

I found this article is very intriguing. Solar billboard, a simple idea, yet brilliant. Bravo to Pacific Gas and Electric for its proactive attitude towards renewable energy. I am quite confident that this will become very common in the near future.

The portion of the article is below. Complete article is here.

Energy-sapping billboards, your days may be numbered. A California electricity supplier says it has installed the nation's first solar-powered billboard, which generates more electricity than it uses. The billboard, roofed with 20 solar panels, is located at 1000 Brannan St. in San Francisco.

"The energy that is collected by the solar panels actually exceeds the amount used by it on a day-to-day basis," said Pacific Gas and Electric (PG&E) spokesperson Jennifer Zelwer of the standard-sized billboard, which proclaims: "This isn't a billboard. It's a power plant."

On sunny days, the sign converts sunlight into about 3.4 kilowatts of energy, which is almost enough to power the household of an average U.S. family of four during the day. Zelwer said the billboard generates about 2.5 kilowatts of energy during cloudy days.
