Home battery storage in Santa Monica is mostly an economics play, with outage protection as the bonus. Because Santa Monica is SCE territory under NEM 3.0, exported solar earns only about a quarter of what grid power costs — so without a battery you're selling cheap by day and buying expensive at night. A battery flips that: you store your midday production and self-consume during the 4-9 PM peak, which is what brings a coastal payback into single digits. It also keeps your home running during the grid outages that hit the Westside, and it pairs cleanly with EV charging, which is common here. We size the system around your real SCE load profile and how your household actually uses power across the day.

Why Santa Monica homeowners choose Helios for storage.

We design and install across Santa Monica — from North of Montana, Sunset Park, and Ocean Park, near the Santa Monica Pier, Palisades Park, and Third Street Promenade.

7+ years across SoCal

Hundreds of installs in 40+ cities — we know SCE, your permit office, and local outage patterns.

How we design your Santa Monica battery.

  1. 1

    How much do you use?

    We pull your last 12 months of SCE data and build an hourly load profile — we size for your real life, not a generic average.

  2. 2

    What matters in an outage?

    We design the backup-loads panel around your definition of "good enough" during a shutoff — fridge, internet, well pump, and AC if you need it.

  3. 3

    Single battery or stackable?

    We model one unit vs. two and show you the real runtime difference for your home and outage exposure.

  4. 4

    Install & commissioning

    We pull every Santa Monica permit, handle Southern California Edison paperwork, and verify the system before we leave. Most installs finish in 1-2 days.

Our promise: real outage-runtime modeling and every cost itemized before you decide, with a 10-year workmanship guarantee on every Santa Monica install.

I interviewed five solar companies. Helios was the only one that pulled my actual SCE usage data instead of guessing. The savings projection they gave me has been within 5% of reality every month since.
Karen L. · Santa Monica · Solar only
Tim and his team were transparent from the first call. We got three quotes — Helios was the only one that itemized everything. The install was clean, on time, and the Powerwall has already paid for itself in peace of mind during the last PSPS event.
Jennifer M. · Pasadena · Solar + battery
We're in the High Fire Threat District and the outages were getting brutal. Helios designed a system around our specific backup needs (fridge, internet, well pump, A/C). When the next PSPS hit, we didn't even notice until our neighbors complained.

Santa Monica battery questions, answered.

How much does a home battery cost in Santa Monica?
A single Tesla Powerwall 3 install typically runs $13,500-$17,500 before incentives; modular Enphase IQ configurations can start lower. Through prepaid-lease financing the federal commercial credit can be passed through on the battery (homeowners no longer claim it directly), and we check whether any remaining SGIP resiliency tier fits your address before quoting.
Can I add a battery to my existing Santa Monica solar system?
Usually yes. AC-coupled batteries like the Enphase IQ line retrofit onto most existing solar systems without redoing the array. We assess your current inverter and panels and tell you whether a retrofit or a paired system is the better value.
Will a battery cover EV charging and evening use?
It can be sized to. Many Santa Monica homes pair a battery with a Level 2 EV charger, drawing on stored solar in the evening instead of peak grid power. We model your combined home-plus-EV load so the battery is sized for how you actually live, not a generic spec.
