NEW BERLIN, Wis. (CBS 58) -- People are moving into Wisconsin's first 'solar-powered' neighborhood.

Red Fox Crossing is in New Berlin and 20 of the 34 houses in the neighborhood have been sold.

All of the houses are designed to produce all the electricity they need for a full calendar year through solar panels.

Houses are connected to a grid to keep power going when the sun is down.

"The beauty of it is functionally there is no difference. So, at the end of the day when you plug in your cell phone charger, it's going to charge your cell phone. Whether it's night, during the day, cloudy, sunny, doesn't matter. Everything is still the same so there are grid-connected solar arrays," said Matt Neumann, CEO of Neumann Companies.

The houses cost more up front because of the panels but officials say the cost is usually made up after about 7 years.
