Output to expect
Cleaning recovery and cost over a stated period
  • Check the units and required inputs before comparing results.
  • Keep the assumptions with a copied result so you can reproduce the calculation later.

How it works

Cleaning recovery and cost over a stated period

Value the energy that cleaning is expected to recover over the period before new soiling, rain or another service. Use a clean-potential baseline or a measured soiled baseline with its documented loss definition.

Lost energy = clean-potential energy × loss fraction, or measured-soiled energy × loss/(1−loss); recovered energy = lost energy × recovery fraction.
