Older 100A panels can't support solar, battery backup, EV chargers, or modern appliances. We upgrade your electrical service to 200A and replace outdated main panels throughout Fresno County and Madera County — permitted, inspected, and done right by a local licensed contractor.
Fresno Local Fact: Over 40% of Fresno homes were built before 1980 and still have 100A electrical service — insufficient for solar, battery backup, and EV charging combined.

Electrical Panel Upgrade in Fresno
Most homes built in Fresno County and Madera County before 1990 were wired with 100A electrical service — enough for the appliances of that era. Today's energy demands are completely different. A central air conditioner, electric range, and water heater can already push a 100A panel close to its limit. Add a solar system, a home battery, and an EV charger, and you're asking a 40-year-old panel to do a job it was never designed for. A 200A service upgrade isn't just about capacity — it's about safety, code compliance, and making your home ready for the next 30 years.
Fresno is the largest city in the Central Valley, with a large stock of older homes built in the 1960s–1980s that commonly have 100A electrical service. We've completed installations throughout Fresno — in zip codes 93701, 93702, 93703, 93704, 93705, 93710, 93720, 93721, 93722, 93726, 93727, 93728, 93730 — and we understand the specific permitting requirements, utility coordination, and local conditions that affect every job here.
Related Services We Offer in Fresno
Every job we do in Fresno starts with a thorough assessment. Here's what we look for and why it matters.
Most solar and battery installations require a panel assessment. If your panel is undersized or outdated, the upgrade happens before or alongside the install.
A Level 2 EV charger draws 40–50A continuously. Most 100A panels don't have the spare capacity — a panel upgrade is often required.
If you're regularly resetting tripped breakers, your panel is overloaded. This is a safety issue, not just an inconvenience.
Adding a room, converting to electric appliances, or installing a heat pump almost always requires additional panel capacity.
Every electrical panel upgrade job in Fresno is permitted where required, inspected, and completed by our licensed crew. We don't subcontract — the same team that quotes the job does the work.
Permitting in Fresno
Panel upgrades in Fresno require a permit from the City of Fresno. We file the permit, coordinate the PG&E service upgrade, and schedule the final inspection. Typical permit timeline is 2–3 weeks.

How It Works
01
We visit your home, assess your current panel, measure your load, and confirm what upgrade is needed. No charge, no obligation.
02
We file the electrical permit with the city building department and coordinate the utility service upgrade with PG&E. This typically takes 1–3 weeks.
03
The physical panel replacement takes 1 day. Power is off for a few hours. We handle everything from the meter to the new panel.
04
The city inspector signs off on the work. PG&E reconnects service. Your home is now ready for solar, battery, and EV charging.
Not always, but it's common in Fresno. Over 40% of Fresno homes were built before 1980 and still have 100A service. In older Fresno neighborhoods like Tower District, Fig Garden, and central Fresno, 100A panels are the norm rather than the exception. We assess your existing panel during the free site visit and tell you upfront if an upgrade is required. If it is, we bundle the panel upgrade with your solar installation — one crew, one permit process, typically completed in 2 days.
The physical panel replacement takes 1 day — power is off for 4–6 hours while we work. Permitting with the City of Fresno Development and Resource Management Department adds 2–3 weeks before we can schedule the work. We handle all permit filings and coordinate with PG&E for the service upgrade. Total project timeline from contract to completion is typically 3–5 weeks.
Panel upgrade costs in Fresno vary based on your current service size (60A, 100A, or 150A), meter location, whether a utility service upgrade is needed from PG&E, and conduit routing requirements. We provide a detailed, itemized written quote at no charge. Call (559) 355-1025 to schedule a free assessment.
Yes — and we strongly recommend it for Fresno homeowners. Bundling saves time (one permit process instead of two), reduces total cost, and means one crew handles everything from the meter to the roof. Most of our Fresno solar projects that require a panel upgrade are completed as a single bundled project. Ask us about bundled pricing when you get your quote.
We install Square D QO, Eaton BR, and Siemens load centers — all NEC 2020-compliant with AFCI and GFCI breakers where required. We do not install Federal Pacific or Zinsco replacements with the same brands. Every panel we install is permitted, inspected, and documented — useful for insurance and future home sale in Fresno.
Call us or submit a quote request. We'll schedule a free site assessment and give you a straight answer — no pressure, no upselling.

PG&E Billing
A large PG&E annual true-up bill can have many causes — some are usage-related, some are equipment-related. Inverter failures, failed strings, panel soiling, and monitoring gaps can all reduce production without you knowing. We can evaluate your system's production history and identify what's driving the bill.
