The certificates issued for this house are good for 15 years, which means more than seven years remain on them. The grid connection is necessary for the certificates to be valid.
SRECs were certificates created to encourage electric utilities to up the percentage of power generated renewably by enabling home and business owners to sell surplus energy to the utility. You will operate under the same agreement, known as a Solar Renewable Energy Certificate, or SREC. The reason why? If this house consumes less power than it produces in any given month, PSEG buys the surplus and pays De Tibarge.

“The government demands that you install a meter, and they come to read it every month,” she says. “Because we had to go through all this, the state allowed us to have almost 40 kilowatts” of generating capacity, she says.Įven though this house powers itself and doesn’t need to be connected to the grid, it has a connection nonetheless. To get the state permits needed to build and equip this house, De Tiberge had to calculate exactly how much electricity they all used. There’s a small fountain next to the front terrace and another one on the pond that sits at the entrance to this farm. The solar panels supply electricity to both the house and an electrolyzer that splits water molecules into hydrogen and oxygen atoms.

But for this house, she went the battery one better by installing a hydrogen generator and fuel cells. The usual solution to this is a backup battery, which she has.
“Because when you have a sunless day, or a flood or a storm that blacks out the city for a week, which happens quite often in the U.S., you’re not covered. “That’s not the only thing you must have,” she says of the solar panels. The house was designed by Le Corbusier, with Edmond Wanner and Francis Quétant finishing the project, in 1928-29 in Grand Sarconnex, Switzerland | Image courtesy Alice De Tibergeĭe Tiberge, who comes from a Swiss family with a knack for living on the cutting edge - her grandfather lived in a house outside Geneva whose design was conceived by Le Corbusier in the late 1920s - had already converted one house she had lived in to solar power, in Skillman in central New Jersey.īut, she says, she didn’t achieve her goal of having a totally self-sustaining house. 1938 watercolor of Villa Ruf, home of De Tibarge’s grandfather, Jean Ruf.
