<prompt> Human: The solar roof wont be cheap Tesla estimated it would cost 38,300 for a two-story home in the Buffalo Niagara region with 2,000 square feet of space. Between subsidies and the value of the energy it will produce, the company said a homeowner who installs one will come out about 11,300 ahead after 30 years.I wonder what type of return 38,000k in the stock market give you. Recognizing that it probably wont cost 38,000k upfront due to tax benefits.  <response>: It will be a lot cheaper and the technology will be a lot better in 10 years. I would wait.
