Keep the lights, AC, and refrigerator on when PG&E goes dark. NMS is a certified Powerwall installer serving the Central Valley.
Two realities drove Powerwall demand through the roof in the Central Valley over the past three years:
1. PG&E Public Safety Power Shutoffs (PSPS) and wildfire-driven outages. The foothill areas above Clovis, Auberry, Oakhurst, and Coarsegold see multi-day PG&E shutoffs during high fire danger. Valley floor cities like Fresno and Madera see fewer PSPS events but still get hit by weather and grid faults. A Powerwall keeps the refrigerator, internet, lights, and key AC zones running automatically when the grid drops.
2. NEM 3.0 changed the math for new Fresno solar. Under the new Net Billing Tariff, exporting daytime solar to PG&E pays only $0.05 to $0.08 per kWh - versus self-consuming that same kWh during the 4 to 9 PM peak window for ~$0.50 of avoided cost. A Powerwall stores your midday solar and discharges it during the expensive peak hours. The economics work in a way grid-tied solar alone can no longer match. See our NEM 3.0 Fresno explainer for the full breakdown.
Powerwall 3 is Tesla's current-generation home battery. A single unit stores 13.5 kWh of usable energy and outputs up to 11.5 kW continuous (more peak power than the older Powerwall 2). It mounts on a wall or floor stand, indoors or outdoors, and communicates with the Tesla app for monitoring, mode switching, and storm prep.
Key Powerwall 3 specs for Fresno homes:
If you are installing solar fresh in Fresno today, designing around Powerwall from day one is the cleanest approach. Powerwall 3's integrated 11.5 kW solar inverter eliminates the need for a separate string or microinverter system, which simplifies the install and reduces equipment cost. NMS sizes the solar array to match your usage shape and the Powerwall capacity - typically a 7 to 10 kW array paired with one or two Powerwalls for a 12,000 kWh/year Fresno home.
If you already have solar - whether it was installed by NMS or another company - we can retrofit a Powerwall to your existing system. The most common path: install Powerwall as an AC-coupled battery, sized to your typical evening usage, with no changes to the original solar inverter or panels. This usually preserves your NEM 2.0 grandfathering (PG&E rules: less than 10 percent PV nameplate increase = same NEM tier).
NMS handles the PG&E paperwork (PIA-PT submission for storage-only addition), the permits with the City of Fresno or your local AHJ, and the SGIP rebate filing.
Two big incentives bring Powerwall cost down for Fresno homeowners:
SGIP (California Self-Generation Incentive Program): Per-kWh rebate for residential battery storage. The general residential tier pays roughly $200/kWh of capacity. The Equity Resiliency tier - for homes in PG&E High Fire Threat District (HFTD) Tier 2/3 zones or for PG&E medical baseline customers - pays substantially more, often covering 85 to 100 percent of total battery cost. Many foothill homes above Clovis, in Auberry, and around Oakhurst qualify for Equity Resiliency. NMS files the application for every Fresno customer.
30% Federal Residential Clean Energy Credit: When Powerwall is installed alongside new solar or added to an existing system, the entire installed cost qualifies for the 30 percent federal tax credit through 2032. This is a credit on your federal taxes, not a rebate, so consult your tax professional on how it applies to your situation.
Recent NMS install in Clovis, CA - 2,400 sq ft home, two adults plus two kids, PG&E E-TOU-C rate plan, typical Clovis summer with 110 degrees F highs:
Installed cost for a single Powerwall 3 in Fresno typically lands between $14,000 and $18,000 before incentives, depending on electrical work, conduit runs, and whether the install is paired with new solar. SGIP rebate and the 30 percent federal solar tax credit (when installed with PV) can offset $4,000 to $7,000 of that. We give every Fresno homeowner a written, itemized quote on the first call - no surprise charges at install.
Usually yes. If your existing system was interconnected before April 14, 2023, you can typically add Powerwall as a 'storage-only addition' without losing NEM 2.0 grandfathering, as long as the original PV nameplate does not change by more than 10 percent. NMS handles the PG&E paperwork.
Yes - when the Powerwall is installed alongside new solar or added to an existing system, the entire installed cost qualifies for the 30 percent residential clean energy credit (also called the federal solar tax credit or ITC). The credit applies through 2032 at the 30 percent rate. Confirm with your tax professional.
A single Powerwall 3 stores 13.5 kWh of usable energy and outputs up to 11.5 kW continuous. For a typical Fresno home running essentials only (refrigerator, lights, internet, ceiling fans, AC for a few key rooms), that is usually 12 to 24 hours of backup. Two Powerwalls usually get most Fresno families through 36+ hours including some AC. Summer AC use shortens runtime; we will model yours specifically.
SGIP (Self-Generation Incentive Program) is a California rebate that pays a per-kWh subsidy for residential battery storage. The general residential tier in PG&E territory pays roughly $200/kWh. The Equity Resiliency tier - for homes in PG&E High Fire Threat District (HFTD) Tier 2/3 zones, or for medical baseline customers - pays significantly more, sometimes covering 85 to 100 percent of battery cost. Many Fresno-area foothill homes qualify for Equity Resiliency. We file the SGIP application for you.
All three are great UL9540-certified batteries. The main differences: Powerwall has the most peak power per unit (11.5 kW vs Enphase's 3.84 kW per IQ 10 unit), the best mobile app, and Tesla's solar inverter integration; Enphase shines in modular installs (you can add capacity in 3.84 kWh increments) and works with any existing inverter; FranklinWH gives you the most flexible electrical panel integration. NMS is certified on all three - we recommend based on your home and usage, not on what we have in the warehouse.
