As Bay Area homes go all-electric — induction, heat pumps, EV charging — losing power stops being an inconvenience and starts meaning no heat, no cooking, and no car charging. That's why battery backup has moved from solar-enthusiast luxury to a practical remodel add-on, especially in PSPS-prone hillside areas.
Why wire for it during the remodel
Even if you don't install the battery now, roughing in for it during an open-wall remodel is dramatically cheaper than retrofitting later. The expensive part is access and the electrical sub-panel work — both of which are already happening if you're renovating.
The pieces
- Backup sub-panel. You choose which circuits the battery protects — usually the fridge, some lights, internet, and now heat/cooking.
- Solar pairing. Batteries make the most sense with solar; the remodel is a good moment to coordinate both.
- Space. Garage wall or exterior-rated location near the panel.
Cost reality
A single battery plus install is a five-figure line item, and multiple batteries scale up from there. Rebates and the structure of time-of-use electricity rates change the payback math, so it's worth modeling against your actual usage rather than a brochure estimate.
