Path-Q Solar

Would shifting laundry and appliance use into daylight improve my solar savings?

Answer

It can improve savings when the billing structure values using solar on site more than exporting it, because daytime use directly replaces some grid purchases; the benefit depends on appliance flexibility and production timing.

Key points

  • Shift flexible loads to periods when the array is producing, not merely to a fixed clock time.
  • Water heating, laundry, dishwashing, and some charging loads may be easier to shift than cooking or refrigeration.
  • Automation or storage may increase consistency but adds cost and complexity.

What it depends on

  • Solar production profile
  • Household load timing and flexibility
  • Export credit and import pricing structure
  • Appliance controls and occupant routines

Risks and trade-offs

  • Manual shifting may be inconvenient and produce less benefit than expected.
  • Running appliances at unsuitable times or adding controls can affect comfort, noise, or equipment life.

Information you may need

  • Hourly usage and production estimates
  • Which loads are flexible
  • Applicable import and export treatment
  • Available appliance controls

Your next step

What to do next

Compare a normal-use profile with a realistic daytime-shifted profile using the applicable bill structure before investing in automation.
