Tesla Inc. has begun taking orders for its remarkable solar roof tiles to be delivered by summer at a price point that could be transformative for the U.S. solar market.

Tesla will begin with production of two of the four styles of solar tile unveiled in October: a smooth glass and a textured glass version. The Tuscan and French slate tiles will be available by the end of this year. Roofing a 2,000 square-foot home in New York state—with 40 percent coverage of active solar tiles and battery backup for night-time use—would cost about $50,000 after federal tax credits and generate $64,000 in energy over 30 years, according to Tesla.

The warranty is for the lifetime of your house.
