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?

Adding storage can affect rate treatment and program eligibility; confirm the current SMUD rules for the specific account.

Should I book before picking a battery?

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