Potting the top cell holders and soldering the voltage tap to busbars should be done throughout the weeks between working sessions whenever possible.

Current number of potted busbars (as of Nov. 6th): 4

Current number of soldered busbars (as of Nov. 6th): 0

Current number of soldered voltage tap sets (as of Nov. 6th): 0 - need to check in bay

...

Placing the cells in the necessary order (steps 6-8) should be done throughout the week between working sessions depending on if we have the necessary materials (enough cells measured, and enough top and bottom plates)

Current number of modules with cells (as of Nov. 6th): 0

  • Spot welding the modules continued

  • Pick up from previous working sessions if need be

  • Continue potting modules

  • The rest of this timeline will offer ~14 days for conditional forecasting and any needed adjustments/ delays to the timeline. Which I am expecting to happen.
