What we review before a Larchmont Powerwall proposal.

Larchmont Powerwall planning should account for utility rules, older electrical equipment, roof and solar timing, equipment placement and the specific backup circuits the homeowner wants protected. A useful estimate should separate battery equipment, backup load design, permits, incentives and exclusions before the project starts.

1. 1Confirm utility details: LADWP or another service territory, rate plan, solar billing assumptions, export rules and interconnection steps.
2. 2Review older-home electrical capacity: main panel rating, breaker space, grounding, meter location, subpanels and backup load panel needs.
3. 3Choose protected loads: refrigerator, internet, lighting, security, garage door, medical equipment and selected outlets before sizing the battery.
4. 4Coordinate solar and roof timing: compare Larchmont solar installation, roof replacement and the Powerwall backup planning guide before finalizing scope.

The final proposal should show Powerwall equipment, Gateway or backup panel scope, utility steps, permit assumptions, financing, rebate assumptions and excluded loads.

Larchmont: LADWP rules, older home panel assessment.

• →LADWP utility review. Verify the actual utility account before planning solar or battery storage. If the account is LADWP, current LADWP solar, export, interconnection and program rules should be reviewed during project planning.
• →Older homes and panel capacity. Some Larchmont homes have older electrical panels or breaker configurations that may require assessment before Powerwall can be installed. We evaluate your panel during the estimate and specify any required electrical work upfront, before you commit.
• →Roof condition before solar + battery. If you plan to add solar with the Powerwall, the roof should be assessed first. Solar and roof timing should be reviewed because panel removal and reinstallation can add cost later. See our Larchmont roofing guide for roof-before-solar planning.
• →Backup configuration. Backup design can protect selected critical circuits or broader coverage depending on battery count, protected loads, solar production and electrical design. Backup duration is subject to review.
• →LADWP and incentive review. LADWP, manufacturer and other incentive pathways should be verified under current program rules before relying on any rebate amount or availability. Eligibility depends on funding, documentation, utility territory and project scope. Home Upgrade Specialist is not a tax advisor.
• →Enphase IQ Battery as an alternative. For Enphase microinverter solar homes, Enphase IQ Battery 5P is a modular alternative to Powerwall. We review both during your estimate.
