Electrical Panel Upgrade in Simi Valley, Ventura County
EZ Power & Light upgrades electrical panels throughout Simi Valley, Ventura County. Simi Valley homeowners and businesses rely on EZ Power & Light for all electrical needs. We serve all of Ventura County — from residential rewires to commercial tenant improvements to whole-home generators.
A panel upgrade in Simi Valley is usually driven by one of three things: a dangerous obsolete panel (Federal Pacific or Zinsco), a panel that's simply full, or a new load — an EV charger, heat pump, or solar + battery — that the existing service can't carry. We see all three across Wood Ranch, Bridle Path, Santa Susana Knolls and the rest of Simi Valley.
We quote flat-rate, never hourly. The owner walks your panel, runs the load calculation, and gives you a written number the same day — and that number is what you pay.
Why Simi Valley homes need panel upgrades
A lot of Simi Valley's housing stock predates the electrical demands of a modern home. Panels installed for a 1960s or 1970s household — a few lights, a stove, a TV — are now being asked to carry EV chargers, induction ranges, heat pumps, and home offices. When a panel is undersized or obsolete, breakers trip, bus bars overheat, and in the worst case it becomes a fire risk.
Federal Pacific and Zinsco panels are a specific concern. Independent testing has shown their breakers fail to trip reliably under overload — and many California insurers now refuse to renew homeowner policies until they're replaced. If you have one in Simi Valley, replacing it is both a safety upgrade and, increasingly, an insurance requirement.

Old Federal Pacific panel was a fire hazard. EZ Power replaced it with a new Square D 200-amp panel and added a whole-home surge protector. Permits pulled, inspection passed. Very professional operation.
