Tesla Energy products include small Powerwalls (7 or 10 kWh modules) and larger Powerpacks (100 kWh modules).

Initially, 80% of the reservations were for Powerpacks, but surprisingly higher demand for home Powerwalls has changed the proportion to 70%/30%. We believe that the split between Powerpacks and Powerwalls is counted on a kWh basis, not on the number of reservations.

The single largest reservation for Powerpacks is 250 units (25 MWh).

Small production has already begun in Fremont, CA, but Tesla Energy's main production site will be at the Gigafactory in Nevada. By the end of this year, the company intends to install a production line and begin production in Q1 2016.
