How much a plug-in solar kit saves on SCE
Last updated
On SCE's average residential rate of 34.4¢/kWh,[source] the example kit (800 W, $1,000) saves about $272 a year and pays for itself in about 3.7 years, assuming typical placement and that you use most of its power at home.
| Plan | Rate used | Savings per year | Payback |
|---|---|---|---|
| Standard rate, no discount | 34.4¢/kWh | $272 | 3.7 years |

Time-of-use
We don't have SCE time-of-use rates in our data yet. In the calculator, choose SCE and "Time-of-use", then enter the off-peak rate from your bill.

CARE and FERA
SCE says CARE takes 32.5% off your electric bill and FERA takes 18%.[source] We haven't checked these against SCE's tariff. Each kWh then costs you less, so a kit saves a little less and takes longer to pay back. Our estimates use these figures.

What a kit can't change
Standard customers pay a fixed charge of about $24.15/month (CARE about $6, FERA about $12) that solar cannot remove.[source] A plug-in kit only reduces the per-kWh part of your bill.
