A solar energy house is currently on display on Munich's Marienhof.
This bungalow is covered with solar panels and actually generates more power than would be required by someone living there.
In fact, if you lived there you could theoretically sell the energy it generates and earn around €2,700 per year.
The house was designed and built by students at the Technical University of Darmstadt. In 2007 it won the Solar Decathalon competition in the US.
The house is now on tour around Germany. It'll remain in Munich until April 15, 2009.
