Tesla Powerwall 3 in Del Rey
The Tesla Powerwall 3 is a 13.5 kWh lithium iron phosphate home battery with a built-in 11.5 kW solar inverter. It stores solar energy for evening use, provides whole-home backup during outages, and integrates with the Tesla app for real-time monitoring. A single Powerwall 3 can back up most Central Valley homes; two units cover high-load households with EV charging.
Del Rey is a tight-knit agricultural community in central Fresno County, tucked between Fresno and Sanger along the citrus and grape growing corridor. Served by ZIP code 93616, Del Rey's residential neighborhoods are predominantly older single-family homes on flat valley terrain — the kind of unobstructed, south-facing rooftops that solar installers love. Summer temperatures in Del Rey regularly hit 100–107°F from June through September, and PG&E bills for a typical 1,600–2,200 sq ft home run $220–$380 during peak cooling months. The community's agricultural character means most homeowners are practical, long-term thinkers who understand the value of owning an asset outright — which is exactly how Robbins Energy approaches solar. No leases, no PPAs, no 20-year contracts. You own your system from day one. Del Rey's proximity to Sanger means Fresno County Building Department processes permits for this area, and Robbins Energy has navigated that process many times for homeowners in this corridor.
Newer suburban homes often have 200-amp panels and solar conduit pre-runs — making Powerwall 3 installation faster and cleaner. The built-in solar inverter means no separate string inverter is needed for new solar + battery installations.
Why Powerwall Makes Sense in Del Rey
- PG&E outages during summer heat events and PSPS events
- High evening electricity bills under NEM 3.0 (store solar, use at night)
- Eliminating grid dependence for households with high AC loads
- EV charging from solar surplus rather than grid power
Who It Is Right For in Del Rey
- Homeowners with existing solar who want battery backup
- New solar + battery installations (Powerwall 3 includes the inverter)
- Households with medical equipment requiring outage protection
- EV owners who want to charge from stored solar overnight
- Homes in PSPS-risk areas (foothills, rural Fresno/Madera/Tulare counties)

Tesla Powerwall 3 Installation Details for Del Rey
System Sizing
One Powerwall 3 (13.5 kWh) covers essential loads for 12–24 hours for most Central Valley homes. Two units are recommended for whole-home backup including AC, or for households with EV charging. Robbins Energy sizes battery systems based on your actual PG&E usage data.
Solar Integration
Powerwall 3 includes a built-in solar inverter — for new installations, no separate string inverter is needed. For retrofits onto existing solar systems, a Gateway 2 or Backup Switch is required. Robbins Energy handles both new installs and retrofits.
Backup Power
Powerwall 3 supports whole-home backup — not just a critical loads panel. During a PG&E outage, your home transitions to battery power in under 20 milliseconds. Storm Watch mode monitors PG&E outage alerts and pre-charges the battery before a PSPS event.
Panel & Electrical
Powerwall 3 installation requires a 200-amp main panel. Homes with 100-amp service (common in older Fresno, Madera, and Tulare County neighborhoods) need a panel upgrade first. Robbins Energy performs panel upgrades as part of the installation. Suburban communities typically have newer housing stock with 200-amp panels and good solar access. Newer developments may have solar conduit pre-runs.
Permitting in Del Rey
Permits issued by: Fresno County Building Department. Battery storage installations require a building permit and PG&E interconnection approval in all Central Valley jurisdictions. Permit timelines vary: Fresno and Clovis typically 2–3 weeks; rural county jurisdictions 3–5 weeks. Robbins Energy handles all permitting. PG&E NEM 3.0 interconnection required. Robbins Energy handles the full interconnection application, which typically takes 4–8 weeks for approval after permit issuance.
Roof & Site Notes
Suburban rooftops generally have good solar access. Newer homes often have 200-amp panels and may have solar conduit pre-runs. Older stock. Many 1960s–1970s homes have 100A panels. Panel upgrades common before solar. Newer homes on outskirts more likely 200A-ready.

Is battery storage worth it in Del Rey under PG&E NEM 3.0?
Under PG&E NEM 3.0, battery storage is essential to maximize the value of your solar investment. Export rates are low; storing solar for evening use avoids buying power at peak rates (4–9 PM). In Del Rey, summer electricity rates peak in the evening when solar production has stopped — battery storage lets you use your own solar power instead of buying from PG&E at peak rates.
What is the outage and PSPS risk in Del Rey?
This valley floor community has low PSPS risk. Battery storage is still valuable for NEM 3.0 optimization — storing midday solar for evening use instead of selling back at low export rates. Low-moderate. PSPS events rare in this valley corridor. Summer heat events occasionally stress the grid. Battery backup worth considering for households with medical equipment.
What is the difference between Powerwall 3 and Powerwall 2?
Powerwall 3 (released 2024) includes a built-in 11.5 kW solar inverter — for new solar installations, no separate string inverter is needed. Powerwall 2 required a separate solar inverter. Powerwall 3 also has higher continuous power output (11.5 kW vs 5 kW) and supports whole-home backup more effectively. Robbins Energy installs Powerwall 3 for new systems and can retrofit Powerwall 2 onto existing solar.
Can Powerwall 3 power my whole house during an outage?
Yes — Powerwall 3 is designed for whole-home backup, not just critical loads. A single unit (13.5 kWh) can power most Central Valley homes for 12–24 hours depending on AC usage. Two units cover high-load households with EV charging. During a PG&E outage, your home transitions to battery power in under 20 milliseconds — most appliances don't even notice the switch.
Does Powerwall 3 qualify for the federal tax credit?
Battery storage systems installed with solar may qualify for the federal Investment Tax Credit (ITC). Tax credit eligibility depends on your individual tax situation. Robbins Energy recommends consulting a tax professional for guidance specific to your circumstances. We do not provide tax advice.
