This is the point, the amount of money used for this acquisition could have been used to bring the Model 3 to market quicker and make batteries in Reno quicker, not to mention any unforeseen problems with production, scaling, and recalls go away that much quicker too. Which is the bigger market? Solar or cars? They might both be similar sized, but demand for solar sure would have been helped by having the Model 3 on the road. Hope the acquisition doesn't hold Tesla back, like most of the market thought at the time.
