Your electrical panel is the heart of your home's power system. It distributes electricity to every circuit in your house, and if it's outdated, undersized, or failing, it puts your entire property at risk. Eleos Electric specializes in electrical panel upgrades throughout Sonoma County — from Windsor and Santa Rosa to Healdsburg, Rohnert Park, Petaluma, Sonoma, and Sebastopol. We've upgraded hundreds of panels across the county, and we handle everything from permits to final inspection.
Many Sonoma County homes were built in the 1960s through 1980s with 100-amp electrical panels that were perfectly adequate for the appliances and electronics of that era. Today, with central air conditioning, EV chargers, home offices, hot tubs, and modern kitchen appliances, those 100-amp panels are pushed far beyond their safe capacity. An overloaded panel doesn't just trip breakers — it creates fire hazards.
The most common panel upgrade we perform is replacing a 100-amp panel with a modern 200-amp service. This upgrade doubles your available electrical capacity and provides room for future additions like EV chargers, solar systems, battery storage, or home additions. Our meter panel replacement starts at $2,900 and includes the panel, main breaker, new breakers for existing circuits, PG&E coordination, Sonoma County building permit, and final inspection.
The process typically takes one to two days. On day one, we install the new panel, transfer all circuits, and coordinate the meter pull and reset with PG&E. Your power is usually off for four to six hours during the switchover. On day two, if needed, we complete any remaining circuit work and prepare for inspection. We schedule the Sonoma County building inspection as part of our service — you don't have to manage that process.
Not every situation requires a full main panel replacement. If your main panel is in good condition but you've run out of breaker spaces, or you need dedicated circuits in a workshop, garage, or ADU (accessory dwelling unit), a sub-panel is an efficient and cost-effective solution. We install sub-panels ranging from 60 to 125 amps, sized appropriately for the intended loads.
Sub-panels are particularly popular with Sonoma County homeowners who are building ADUs — a common addition in Windsor, Santa Rosa, and Rohnert Park where the housing demand has driven significant ADU construction. We ensure the sub-panel installation meets all California building code requirements, including proper feeder sizing, grounding, and bonding.
Individual breaker replacement is a common service we provide. Breakers wear out over time, especially if they've tripped frequently. We replace standard breakers, GFCI breakers, AFCI breakers, and combination AFCI/GFCI breakers with quality components from trusted manufacturers. We also perform panel maintenance including bus bar tightening, connection inspection, and corrosion treatment.
Every panel upgrade requires a building permit from Sonoma County Permit and Resource Management (PRMD). We handle the entire permitting process, from application to final inspection. This includes preparing the permit application, providing required documentation, scheduling the inspection, and being present for the inspector's review. Our long-standing relationship with Sonoma County inspectors means we know exactly what they look for, and our work passes inspection consistently.
Whether your home is in Healdsburg's historic district, Petaluma's east side, or a rural property outside Sebastopol, we navigate the specific requirements for your jurisdiction and ensure full compliance.

Common signs: breakers that trip repeatedly, a panel under 100 amps in a modern home, Federal Pacific or Zinsco brand panels, scorch marks or rust inside the cabinet, or a panel that cannot fit another circuit. Eleos does a free panel assessment as part of any quote.
Most Sonoma County homes under 2,000 sq ft need at least 100 amps; homes with central AC, EV charging, or electric range/water heater typically need 200 amps. Larger estates or homes planning solar/battery should size to 225 or 400 amps.
Typical residential panel upgrades in Sonoma County run $2,800 to $4,800 including permit, meter work coordination with PG&E, and inspection. Costs go up for service mast rebuild, long conductor runs, or service relocations.
Most jobs are completed in a single day. Power is shut off for 4โ8 hours during the change-out. Eleos coordinates the PG&E disconnect/reconnect and building-department inspection so you are back on power the same day.
Yes โ every city and the county require a permit for panel and service work. Eleos pulls the permit under CSLB #1009044, schedules the inspection, and signs off the permit when work is complete.
