What Is Time-of-Use Electricity Pricing?
By JC Pacific Corp Published 2026-09-01 Last professionally reviewed: September 2026
Time-of-use pricing charges different electricity rates during different hours. Electricity is usually more expensive during designated peak periods and less expensive during off-peak periods.
Why do time-of-use rates matter for solar homes?
Solar production may peak earlier than household demand. Under some tariffs, homeowners may receive relatively low export credits during solar-heavy hours and pay higher rates when buying electricity later. A battery may shift stored energy into higher-cost periods.
Which household activities can be shifted?
When practical:
- Electric-vehicle charging
- Laundry
- Dishwasher use
- Pool pumps
- Water heating
- Battery charging
- Certain cooling strategies
Safety, comfort, equipment, and utility rules still matter.
How should buyers evaluate past bills?
Review:
- Total usage
- Import by time period
- Solar production
- Export credits
- Rate plan
- Seasonal changes
- True-up or annual settlement
- Electric-vehicle usage
- Battery activity
- Fixed charges
The seller's usage may differ substantially from the buyer's.

Solar agreements, utility tariffs, incentives, tax rules, financing requirements, equipment warranties, and transfer procedures vary and change frequently. Buyers, sellers, and owners should consult appropriately licensed legal, tax, lending, insurance, real estate, electrical, solar, and appraisal professionals regarding a specific property. Never access, disconnect, modify, repair, or remove solar, battery, electrical, or utility equipment without appropriate authorization and professional qualifications. Battery systems may retain dangerous electrical energy even when other power appears disconnected.
