SCE time-of-use review
SCE time-of-use rates can change the solar and battery conversation.
Time-of-use rates make timing matter. For many SCE homeowners, the important question is not only how much electricity the home uses, but when it uses power and whether solar-only or solar-plus-battery assumptions match the actual bill.
TOU-D 4-9
SCE describes this residential time-of-use plan as having the highest summer weekday rates from 4 p.m. to 9 p.m.
TOU-D 5-8
SCE describes this plan as having the highest summer weekday rates from 5 p.m. to 8 p.m.
TOU-D-PRIME
SCE positions PRIME for homes with clean-energy technologies such as EVs, batteries, or electric heat pumps, with an important 4 p.m. to 9 p.m. window.
Why this matters
Solar production and evening usage are not the same problem
A solar system may produce a lot of energy during the day, while the home may still use expensive grid energy later. That is why SCE time-of-use context belongs in the review before anyone makes a serious solar or battery recommendation.
The SCE Solar Billing Plan guide explains why export credits and grid-energy charges matter. The battery guide explains when storage should be evaluated without treating it as automatic.
Review signals
What a high-bill review should check
- Large usage after 4 p.m. or 5 p.m.
- High summer air-conditioning bills
- EV charging, pool equipment, or electric heat loads
- Solar-only assumptions that ignore evening grid usage
- Battery claims that are not checked against the actual bill
Look at the bill first
The bill shows the rate-plan context and usage pattern that a generic quote cannot see.
Separate solar from battery fit
A high bill may justify a solar review, but the battery question depends on timing, backup needs, and cost.
Avoid fake instant savings
A real review should not pretend that one calculator number can replace the actual SCE bill.
Next step
Start with the bill before choosing solar-only or solar-plus-battery
EnergyRateLock uses the SCE bill review to keep the conversation grounded. You can start without uploading a bill, but a recent bill is required before a real appointment is scheduled. The goal is to decide whether the home deserves a closer solar or battery review, not to force every homeowner into the same answer.
