Why Powerwall matters in Altadena.

Altadena is in a High Fire Threat District served by SCE. PSPS events — planned utility shutoffs during extreme fire weather — have affected this community directly. A Tesla Powerwall changes the outage equation:

• →Automatic backup for selected loads. When the grid goes out, a properly approved Powerwall and Gateway design can switch protected circuits to battery automatically. Coverage depends on the final electrical configuration, battery count and backup-load selection.
• →Solar may extend PSPS coverage. During an outage, solar panels may recharge the Powerwall when the approved equipment configuration, sunlight, battery settings and system limits allow. Runtime depends on protected loads, battery size, solar production and weather. Specific runtime depends on approved design, battery capacity, solar production and actual usage.
• →No noise, no exhaust. In a densely populated foothill community, Powerwall’s silent operation avoids the exhaust and noise associated with generators — important for a community where air quality during fire events is already a concern.

Powerwall + solar in Altadena: SCE-modeled battery planning.

• →SCE Net Billing applies in Altadena. Altadena is in SCE territory. Under Net Billing, export credits are time-varying and often lower than retail import rates, so homeowners should compare solar-only and solar-plus-battery designs before choosing a system.
• →Store solar, use at peak. A Powerwall charged by solar during the day and discharged during the SCE evening peak rate window offsets the highest-cost grid power of the day. Actual value depends on your rate plan and usage — we do not promise a specific financial outcome or payback periods.

SGIP eligibility review for Altadena battery projects.

SGIP may help qualifying battery projects, but it is not an automatic discount. Altadena projects should be reviewed against current SGIP rules, waitlists, funding status and documentation requirements before a rebate is included in the budget.

• →Eligibility can depend on utility territory, program administrator, income or equity criteria, battery size, reservation window, documentation and available funding and approval.
• →SGIP requires a permitted and inspected installation. We coordinate permitting for every Altadena Powerwall project.
• →We are not a tax advisor. Consult a qualified professional for tax questions related to SGIP or battery installations.
