Evaluating Tesla’s Powerwall: Finding a Home for Residential Energy Storage

June 11, 2015 | State of the Market Report

Electric vehicle maker Tesla Motors has unveiled two stationary storage products targeting residential – and larger systems, too. We find that Tesla advertises a very low price point relative to other battery players, but its products require further hardware that will double the cost to the end consumer. The company is betting on margin expansion and announced it will lose money on every system it sells, initially. However, despite its low priced claims, the revenue model for residential storage is tenuous, leading most consumers to focus on backup power.
