Renewable Energy, Solar & Wind Manufacturing worked example

Solar Capacity Ramp at 65% line availability during ramp: a worked example

This worked example runs the solar capacity ramp numbers for a tougher week than the baseline: 65% line availability during ramp instead of the typical 90%. Estimate solar capacity ramp for renewable energy, solar and wind manufacturing using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.

The inputs for this scenario

  • Cells or modules produced per takt cycle: 4 units / cycle (held at the documented default)
  • Scheduled ramp cycles in the period: 480 cycles (held at the documented default)
  • Line availability during ramp (uptime): 65 % (the input this scenario stresses; the baseline uses 90)
  • First-pass lamination/cell yield during ramp: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross solar capacity ramp capacity = solar capacity ramp output per cycle × available solar capacity ramp cycles.
  • Good solar capacity ramp capacity works out to 1,211 units at these inputs, and this is the headline figure for the scenario.
  • Gross solar capacity ramp capacity works out to 1,920 units at these inputs.
  • Solar capacity ramp downtime loss works out to 672 units at these inputs.
  • Solar capacity ramp yield loss works out to 37.44 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where line availability during ramp sits at 90% and the headline result is 1,676 units, this scenario comes in 27.78% below the baseline at 1,211 units.
  • Use it during line commissioning, tool add-on, or debottlenecking when availability and yield are still climbing toward mature targets. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Good solar capacity ramp capacity: 1,211 units (headline result)
  • Gross solar capacity ramp capacity: 1,920 units
  • Solar capacity ramp downtime loss: 672 units
  • Solar capacity ramp yield loss: 37.44 units
