Anatomy of a net zero-energy home
Clearly, solar power is a big part of the Solar Decathlon homes, but all of the homes used energy-efficiency extensively, including high levels of insulation, LED lighting, and efficient appliances. Here, a Department of Energy display on the National Mall shows some of the key components of a low-energy home, including the different types of insulation on the right. On the left is a grid-tied solar photovoltaic panel, or a panel that makes electricity from the sun. For the first time, the solar village was connected to the local power grid, so the homes did not need batteries to store excess electricity.
