Napa Electrician

The cost of hiring a custom home electrician in Napa depends on the home’s size, layout, and the complexity of the electrical systems being installed.

Typical project ranges include:

• $25,000 for a small, simple ADU

• $100,000 for a roughly 2,500 sq ft home with standard electrical and solar

• $350,000 for a roughly 3,500 sq ft smart home with solar and integrated audio-visual systems

• $1,500,000 for a 10,000 sq ft estate with extensive lighting design, solar, and large battery systems

What affects custom home electrical pricing?

• Device count
  Pricing scales with the number of outlets, fixtures, switches, appliances, and control points.

• Home footprint
  Larger homes typically require more circuits, devices, and code-mandated infrastructure.

Solar system pricing in Napa Valley varies based on system size, mounting method, and the condition of the existing electrical service.

Common solar system costs include:

• $12,500 for a 2.5 kW roof-mounted system with Enphase microinverters

• $30,500 for a 6 kW roof-mounted system with Enphase microinverters and a service panel upgrade

• $54,000 for a 6.5 kW ground-mounted system located approximately 100 feet from the main panel

What affects solar pricing?

• System size
  Larger systems usually have a lower cost per watt than smaller installations.

• Mount type
  Roof-mounted systems are typically much less expensive than ground-mounted systems. Tile roofs increase labor cost.

• Existing electrical panel
  Homes without a solar-ready service panel often require an upgrade.

Battery backup systems provide stored energy during outages and can support load management.

Typical battery system pricing:

• $15,000 for two 5 kWh Enphase batteries

• $27,000 for one 13.5 kWh Tesla Powerwall with one 13.5 kWh expansion pack

What affects battery pricing?

• Number of batteries
  More storage capacity increases total cost.

• Battery location
  Garage or driveway-adjacent installations may require safety bollards or added protection.

• Battery manufacturer
  Each brand uses different hardware, software, and component configurations.

Backup generator pricing depends on how much of the home you want to power and the electrical upgrades required.

Typical generator system costs include:

• $2,000 for a manual interlock, outlet, and portable generator connection

• $28,000 for a 26 kW whole-home generator with automatic transfer switch and subpanel

• $60,000 for a 60 kW whole-home generator with automatic transfer switch

What affects generator pricing?

• Generator size
  Backing up an entire home costs more than supporting essential circuits.

• Electrical service requirements
  Some homes require panel upgrades before a generator can be installed.

• Distance from the house
  Longer generator setbacks increase trenching and installation cost.

Service panel upgrades are commonly required for solar, batteries, EV chargers, and generators.

Typical panel upgrade costs:

• $3,800 for a 200A upgrade when no relocation is required

• $7,500 for a 200A upgrade with panel relocation

• $8,000 for advanced power management panels with remote monitoring

What affects panel upgrade pricing?

• Panel size
  Upgrades to 200A are standard. Upgrading to 325A adds approximately $1,400.

• Gas meter clearance
  PG&E requires a minimum 4-foot clearance between panels and gas meters.

• Underground service limits
  Some Napa neighborhoods are restricted to 100A service and require trenching to increase capacity.

Smart lighting costs depend on system type, wiring access, and the number of circuits being controlled.

Typical smart lighting system ranges:

• $1,000 to $7,000 for Lutron Caseta retrofits, outdoor lighting, or ADUs

• $5,000 to $20,000 for Lutron RadioRA 3 retrofits during remodels

• $10,000 to $70,000 for Lutron HomeWorks or Savant systems in new construction

What affects smart lighting pricing?

• Control platform complexity

• Number of lighting circuits

• Retrofit versus new construction
