Electrical Panel Upgrade Bay Area — 200A Service for Solar, EV & Heat Pumps
Nabu Energy designs, permits, and installs residential and commercial electrical panel upgrades for homeowners and businesses across the Bay Area, California. From aging 100-amp panels to full 200-amp service upgrades, we handle the design, permitting, PG&E coordination, and installation end to end — with zero sales commission.
Electrical Panel Upgrades for Residential and Commercial Properties Across the Bay Area
As homes and businesses add EV chargers, heat pumps, induction ranges, and battery systems, older electrical panels are being pushed far beyond what they were built to handle. Nabu Energy designs and installs code-compliant electrical panel and service upgrades for both residential and commercial properties throughout the Bay Area — sized correctly for the loads you have today and the electrification you are planning for tomorrow.
Residential Electrical Panel Upgrades
Most Bay Area homes were wired with 100-amp (or smaller) service that simply cannot support modern electric loads. We upgrade main panels to 200-amp service, replace unsafe or recalled panels, add subpanels, and coordinate the utility and permit process end to end. Whether you are preparing for an EV charger, a heat pump, or a full home electrification project, we right-size your panel so it is safe, permitted, and ready to grow with you.
Commercial Electrical Panel Upgrades
Growing businesses, multifamily buildings, and commercial fleets need electrical capacity that keeps pace with new equipment and EV charging demand. Nabu Energy handles commercial service upgrades, switchgear, and distribution panel work with full permitting and utility coordination — minimizing downtime while bringing your property up to code and ready for higher loads.
Licensed, Bonded, and Fully Accredited
Electrical panel and service work is life-safety work. Nabu Energy is a licensed California electrical contractor, and every panel upgrade we perform is engineered to code, permitted with your local building department, and inspected by your utility before it is energized. When you hire us, licensed electricians do the work — not subcontracted crews.
Credentials that protect your home and your investment.

An electrical panel upgrade touches the most dangerous part of your home’s wiring — the main service. A licensed electrician performs the load calculation correctly, sizes the service to code, coordinates the utility disconnect safely, and pulls the permit so the work is inspected. Cut-rate or unpermitted panel work can fail inspection, void insurance, and create real fire and shock hazards. With Nabu Energy, licensed electricians handle every step.
Workmanship and Equipment Warranties
A panel upgrade should last for decades, and we stand behind ours in writing. Every installation is backed by both the manufacturer’s equipment warranty and our own workmanship warranty, so you are covered on the hardware and on the quality of the installation.
Manufacturer Equipment Warranties
We install panels, breakers, and service equipment from trusted, code-listed manufacturers, and we register the equipment warranty on your behalf. Because the gear is installed to spec by licensed electricians, you keep the full manufacturer coverage — improper installation is one of the most common reasons equipment warranties get denied, and we make sure that never happens.
Nabu Energy Workmanship Warranty
On top of the manufacturer coverage, Nabu Energy warranties our own workmanship. If anything related to our installation needs attention, we come back and make it right. With zero sales commission, our team’s only incentive is doing the job correctly the first time — which is exactly what a long workmanship warranty rewards.
Why Choose Nabu Energy
The Bay Area’s zero-commission electrical panel upgrade specialists.
Traditional electrical companies pay their salespeople commission, which inflates your quote and rewards overselling. Nabu Energy pays zero sales commission. You deal directly with the licensed electricians doing the work, and your price reflects the actual scope of your panel upgrade — nothing more.
Every quote breaks down the panel, breakers, permit, utility coordination, and labor line by line, so you can see exactly what you are paying for — no vague lump sums and no surprise change orders.
Because no one earns a commission, we recommend the panel size your loads actually require — not the biggest service we can sell you. If a subpanel solves your problem, that is what we quote.
We start with a proper load calculation based on your current and planned electrical use, then size your service to match. You get capacity for EV charging, heat pumps, and future electrification without paying for headroom you will never use.

Frequently Asked Questions
Most residential electrical panel upgrades in the Bay Area range from about $2,500 to $4,500 for a standard 200-amp main panel replacement, with typical projects landing near $3,000–$3,800. Your final price depends on the amperage you need, whether the meter and service entrance must be relocated, the length of the utility run, and any panel or wiring that must be brought up to current code. Because Nabu Energy charges zero sales commission, your quote reflects the real scope of the work — not a padded, commission-driven number. We provide a fixed, itemized price before any work begins.
Common signs include a panel rated at 100 amps or less, a fuse box or a known recalled panel brand (such as Federal Pacific or Zinsco), breakers that trip frequently, flickering or dimming lights, warm panel covers, or simply running out of open breaker slots. You also need more capacity before adding an EV charger, heat pump, induction range, or home battery. If any of these apply, a licensed Nabu Energy electrician can perform a load calculation and tell you honestly whether an upgrade is required.
A typical residential main-panel upgrade is completed in one day, usually 4 to 8 hours of on-site work. Power is off for part of that day while we swap the panel and coordinate the utility disconnect and reconnect. The full project timeline — including the permit, utility coordination, and the final inspection — usually runs one to three weeks from signed quote to inspected completion, depending on your city’s permitting and your utility’s scheduling. We manage all of that coordination for you.
Yes. A main electrical panel or service upgrade always requires a permit from your local building department, and the utility must disconnect and reconnect your service. This is not optional — unpermitted panel work can fail a home inspection at sale, void your insurance, and create serious safety hazards. Nabu Energy pulls the permit, schedules the utility disconnect and reconnect, and arranges the final inspection so your upgrade is fully legal, documented, and inspected. You never have to navigate the permit or utility process yourself.
For most Bay Area homes adding modern electric loads, 200-amp service is the practical standard — it comfortably supports an EV charger, a heat pump, and future electrification without maxing out. Some smaller homes are fine with a 125- or 150-amp upgrade, and some larger or all-electric homes may need 320-amp service. Rather than default to the biggest (and most expensive) option, we run a load calculation and recommend the amperage your home actually needs.
Absolutely — that is one of the most common reasons Bay Area homeowners call us. EV chargers and heat pumps add large, continuous loads that older panels often cannot support safely. We size your new panel and service for the specific equipment you are installing, plus reasonable room to grow, and we can coordinate the panel upgrade and the new circuit together so everything is permitted and inspected in one project. This often qualifies you for available electrification and EV-charging incentives as well.
Nabu Energy is a licensed California electrical contractor that charges zero sales commission, so you work directly with the electricians doing the work and get an honest, right-sized quote. We handle the load calculation, the permit, the utility coordination, and the inspection end to end, back every job with a workmanship warranty, and serve homeowners and businesses across the Bay Area — San Jose, Santa Clara, Sunnyvale, Fremont, and the surrounding communities. You get transparent pricing and code-compliant work from a team whose only incentive is doing the job right.
Do You Need an Electrical Panel Upgrade Before Solar or an EV Charger?
Short answer: if your main panel is 100A, or a legacy split-bus design, usually yes. Adding solar, a battery, a Level 2 EV charger or a heat pump changes the load calculation your panel has to satisfy, and an undersized or obsolete panel is the single most common reason a permit gets held up in the Bay Area.
We tell you before you commit. A load calculation costs you nothing, and it is the difference between an inspection that passes first time and one that does not. If your existing panel is fine, we will say so — we work on zero sales commission, so nobody here earns more by selling you an upgrade you do not need.
