Hi Jarrett,

I took the equipment spec sheet for the prismatic line and this is what it
said:





*With each 16 kWh Sol-Ark system using 16 prismatic 314Ah cells, and a
prismatic line capable of handling approximately 95 cells per minute, the
daily output for two 8-hour shifts can be calculated as follows:Cells
produced per day: 95 cells/min×60 min/hour×16 hours=91,200 cells Modules
produced per day: 91,200 cells/16 cell system=5,700 modulesThis is the
theoretical maximum, assuming assembly processes downstream (module, pack,
and testing) keep up with cell processing, with no significant bottlenecks.
This calculation is valid for the specified 16x 314Ah cell configuration
per system. Actual output may be lower based on process specifics or
technical constraints in the pack assembly area.*

The numbers below I double checked with Kevin from what I gathered on AI as
well.

1) Pack/Module integration time: 1-3

2)  Testing & Aging Cycle duration: Our machines do EOL (End of Line)
testing.  For a full charge discharge cycle I would say 24 - 72hrs.  I
think we can get away with doing 24hrs on select systems for random
testing/QC.  Brian thinks we will need to do every unit for the first few
hundred or so to get all the kinks out.

3)Quantity & Timeline for production: 1GW in 365 days.  That is producing
171.23 units a day.

Below is the revised worksheet with prices for each component.  I switched
the cell price to $60 as well.  I did not add labor to the worksheet below.
