Solar powered billboards unveiled by Bulgaria

We’ve seen some pretty green billboards before that unlike their energy sucking counterparts use up renewable energy to power up, like the one in Times Square New York. This time it’s the Bulgarians busy rolling out eco-friendly billboards. The southeastern European nation will now unveil the world’s first LED screen with an integrated solar panel, a technology that could just change the way billboards work and function forever. And these aren’t those puny little LED screens you might’ve come across before. These are seriously huge, big enough to integrate a solar panel that generates as much as 5 kilowatts of solar energy. The best part is, this self powered screen can be used in areas with no grid connections whatsoever, like for example, highways.

Having those mighty huge billboard screens go solar powered could sure help save a load of energy indeed!
