Solar Offset Calculator with solar or renewable electricity of 362,500 kWh: a worked example

Suppose solar or renewable electricity falls to 362,500 kWh. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate the share of facility electricity use offset by on-site solar, purchased renewable electricity, or RECs.

The inputs for this scenario

  • Solar or renewable electricity: 362,500 kWh (the input this scenario stresses; the baseline uses 725,000)
  • Total facility electricity use: 2,400,000 kWh (held at the documented default)
  • Percent conversion factor: 100 x (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Renewable offset share = solar or renewable electricity รท total facility electricity use.
  • Solar or renewable electricity offset works out to 15.1 % at these inputs, and this is the headline figure for the scenario.
  • Renewable offset share works out to 0.15 share at these inputs.
  • Percent conversion factor works out to 100 x at these inputs.
  • Total facility electricity use works out to 2,400,000 kWh at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where solar or renewable electricity sits at 725,000 kWh and the headline result is 30.21 %, this scenario comes in 50% below the baseline at 15.1 %.
  • It computes the percent of a facility's total electricity consumption that is offset by solar or other renewable generation. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Solar or renewable electricity offset: 15.1 % (headline result)
