Questions existing solar owners should ask

Are you on the original Net Energy Metering rate or already on the Solar and Storage Rate?
Do you want a battery for backup, incentive value, evening peak coverage, or all three?
Will the project require changes to the system size, inverter setup, or interconnection paperwork?

Why SMUD rate status matters

SMUD says many original NEM customers may remain on that rate through Dec. 31, 2030.
SMUD says current NEM customers who add battery storage and want My Energy Optimizer Partner+ incentives will be placed on SSR.
A property review helps compare incentive value against rate and system-design changes.

Common questions

Can I add a battery if I already have solar?

Often yes, but the right path depends on existing equipment, SMUD rate status, interconnection, and program eligibility.

Will adding a battery affect NEM status?

SMUD says existing NEM customers who add battery storage to receive incentives will be placed on the Solar and Storage Rate.

Should I book before picking a battery?

Yes. A review before equipment selection can help avoid missing program, rate, or backup-design details.
