In total, Tesla Energy delivered over 25 MWh of energy storage in the Q1 of 2016 – to customers on four continents (North America, Asia, Europe and Africa).

25 MWh is 25,000 kWh or nearly 278x 90 kWh

Compared to the 14,810 EVs Tesla sold in the first three months, and even assuming smaller 70/85 kWh packs in the mix, Tesla Energy battery sales stands at just a few percentage points (maybe 2-2.5%) of total battery capacity used.

The 25 MWh of capacity was broken out as follows:

over 2,500 Powerwalls (currently only in 6.4 kWh version)

nearly 100 Powerpacks – 100 kWh each (see pricing announcement)
