Tesla CEO and 1997 Wharton graduate Elon Musk unveiled his company’s new solar roofs last Friday evening, according to Bloomberg Technology.

The roofs enclose conventional solar panels yet look identical to normal roofs. Musk said they are “tough as steel” and have “a quasi-infinite lifetime,” Bloomberg Technology reported.

Musk claims that purchasing a solar roof will save customers more money than buying a normal shingled roof and grid electricity.

At the unveiling, the audience toured a house powered by a Tesla solar roof.  During the night, this house stores the collected solar energy in Tesla Powerwall batteries.

While the tiles currently hamper the panels’ energy efficiency by two percent, Musk told reporters he anticipates that future developments will enhance their efficiency.

The roof tiles are available in four different designs.
