In the past few years battery technology has advanced at a rapid rate, resulting in a rapid decrease in the cost of electric storage and the associated systems (Fig 1).  Although this has been driven primarily by electric vehicle adoption, home battery systems have been direct beneficiaries. According to Bloomberg New Energy Finance “Lithium-ion battery packs are selling at an average price of $209 a kilowatt-hour, down 24 percent from a year ago and about a fifth of what it was in 2010, a Bloomberg New Energy Finance survey shows. The rate has further to fall — reaching below $100 a kilowatt-hour by 2025, according to a report by BNEF analyst James Frith.  Developers of stationary storage systems — like the kind that back up rooftop solar panels — can expect to pay 51 percent more than automakers because of much lower order volumes.”
