batteries :)

  Could you clarify? Tesla needs batteries. SolarCity does not need batteries except in jurisdictions that make having a battery significantly favorable over having one. Also, the high energy density batteries that Tesla needs are, IMO, mostly unnecessary for stationary use. Compare Powerwall prices to lead-acid -- lead-acid wins hands down. Sure, the lead acid batteries are heavy, but that's not a problem if you plunk them in the basement or crawlspace.
