Battery storage in Carlsbad, CA
The state's net billing tariff usually credits exported power below the retail rate. A battery is one way homeowners here use more of their own solar power at night.
Why net billing changes the battery question
The CPUC says export compensation under the net billing tariff is usually lower than the retail rate, but can rise above it on late summer evenings. It also says customers can get more bill savings by adding battery storage, so they can use or export stored energy during those high-value hours. Whether a battery pays off for a given home depends on its usage, its rate plan, and its price, and none of that is something this site can tell you.
Carlsbad's online permit portal lists a contractor-only SolarAPP+ permit type for residential photovoltaic and battery systems, and Encinitas accepts solar-plus-battery permits through SolarAPP+ as well. Ask the contractor we connect you with for a written, itemized quote that prices the battery separately. The billing rules behind this are in the net billing guide.
