Panel Build Cost at 72% panel build scope included: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop panel build scope included to 72%, then walk the calculation through step by step. Estimate control panel build cost from panel count, cost per panel, included build scope, and fixed test or certification cost.

The inputs for this scenario

  • Control panel count: 5 panels (held at the documented default)
  • Loaded panel cost per panel: 32,000 $ / panel (held at the documented default)
  • Panel build scope included: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed panel test and certification cost: 9,500 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable panel build cost = control panel count × loaded panel cost per panel × panel build scope included.
  • Total panel build cost works out to 124,700 $ at these inputs, and this is the headline figure for the scenario.
  • Loaded panel cost per panel works out to 24,940 $ / panel at these inputs.
  • Variable panel build cost works out to 115,200 $ at these inputs.
  • Fixed panel test and certification cost works out to 9,500 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where panel build scope included sits at 100% and the headline result is 169,500 $, this scenario comes in 26.43% below the baseline at 124,700 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to panel build scope included, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It uses one loaded cost per panel, so a job mixing simple junction panels with complex multi-drive control panels needs to be split or weighted rather than averaged.

Results at a glance

  • Total panel build cost: 124,700 $ (headline result)
  • Loaded panel cost per panel: 24,940 $ / panel
  • Variable panel build cost: 115,200 $
  • Fixed panel test and certification cost: 9,500 $
