Tesla's Solar Roof Is Cheaper Than Expected (Tom Randall, 5/26/17, Bloomberg)

Tesla Inc. has begun taking $1,000 deposits for its remarkable solar roof tiles--to be delivered this summer at a price point that could expand the U.S. solar market. 

Tesla will begin with production of two of the four styles it unveiled in October: a smooth glass and a textured glass tile. The French slate and sculpted Tuscan versions of the tile will be available in 6 to 9 months.  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's website calculator. 

That's more expensive upfront than a typical roof, but less expensive than a typical roof with traditional solar and back-up batteries. The warranty is for the lifetime of your home. 

"The pricing is better than I expected, better than everyone expected," said Hugh Bromley, a solar analyst at Bloomberg New Energy Finance who had been skeptical about the potential market impact of the new product. Tesla's cost for active solar tiles is about $42 per square foot, "significantly below" BNEF's prior estimate of $68 per square foot, Bromley said.
