FAQ❓ Los Angeles & Orange County (Southern California Edison (SCE)) Solar & Battery FAQsAnswers on local TOU windows, export credits, and battery payback
What is the bestSCE rate plan for solar and battery in Southern California?
TOU-D-PRIME is the mandatory and optimal rate plan for SCE customers with solar and a home battery. It offers lower daytime/overnight off-peak rates (~25¢/kWh) while rewarding battery self-consumption during the expensive 4:00 PM – 9:00 PM peak window (~59¢/kWh).
How many kWh of battery storage do I need for an Inland Empire or OC home with central AC?
For coastal LA/OC homes, a single 14.3kWh WallMount battery (or 12.2kWh–18.3kWh EcoFlow Delta Pro Ultra) is sufficient. For hotter Inland Empire homes (Riverside, San Bernardino, Corona) running 4-ton+ AC units after 4:00 PM, 28.6kWh (two 14.3kWh EG4 WallMount batteries) is recommended.
