An electrical panel is the heart of your commercial building. It takes utility power from the street and distributes it safely to every circuit, fixture, and piece of equipment inside. When a panel is undersized, outdated, or failing, the symptoms show up everywhere — flickering lights, tripped breakers during normal operation, hot panel covers, and nuisance downtime that costs you money every time it happens.
At Solivance Electric LLC, panel upgrades are one of our most requested services across Houston, Cypress, Katy, and Memorial. Below we walk through the warning signs that tell you it is time for an upgrade, what the process looks like, and what a modern commercial service should do for your building.
7 Warning Signs Your Commercial Panel Needs an Upgrade
Panels rarely fail all at once. They send signals for months — sometimes years — before something gives. Here is what to watch for.
1. Flickering or Dimming Lights
If your lights dim every time an HVAC compressor kicks on, a compressor pump starts, or a rooftop unit cycles, your service is likely undersized for the real load. A modern panel with correctly sized feeders should not react visibly to normal equipment starts.
2. Breakers Tripping Under Normal Load
A breaker is supposed to trip when something is wrong — a short, a ground fault, or a genuine overload. If yours trip during regular business hours with normal equipment running, either the circuits are overloaded or the breakers themselves are weak and need replacement alongside the panel.
3. A Warm or Hot Panel Cover
Walk up and touch the front of your panel. It should feel the same temperature as the wall around it. A panel that is warm, hot, or humming audibly has loose connections, undersized conductors, or failing breakers inside — and that is the beginning of a fire.
4. Burning Smell or Visible Scorching
Any smell of burning plastic near the panel is an emergency. Same with visible scorch marks, melted insulation, or discoloration around breakers. Stop using the affected circuits and call a licensed electrician the same day.
5. A 60A or 100A Service on a Modern Load
A lot of older commercial buildings in the Houston area still run on 60A or 100A service entrances that were specified decades ago. Today’s buildings run high-efficiency HVAC, LED lighting with drivers, server rooms, EV chargers, and point-of-sale systems — loads that the original service was never designed to handle.
6. You Cannot Add Any More Circuits
If every slot in your panel is full and you need to add a circuit for new equipment, a tenant buildout, or an EV charger, it is usually cheaper to upgrade the whole panel than to tack on a sub-panel that bandages the problem.
7. Fuse Box or Obsolete Brand Panel
If your building still has a fuse box or a panel brand with known failure history (Federal Pacific, Zinsco, certain Challenger panels), insurance carriers are increasingly refusing to cover the property until it is replaced. A panel upgrade solves the safety and insurability issue in one step.
What a Panel Upgrade Actually Does
When Solivance Electric performs a commercial panel upgrade, we replace the service entrance cable, meter base, main breaker, and panel as a single, code-compliant system. The outcome:
- Higher capacity (typical upgrades go from 100A to 200A, 200A to 400A, or to custom switchgear configurations)
- Modern arc-fault and ground-fault protection where code requires
- Room for future circuits — EV chargers, new HVAC, server gear, additional tenants
- Full compliance with the current NEC and local Houston amendments
- Lower insurance exposure and fewer nuisance outages
The Upgrade Process — Step by Step
A straightforward commercial panel upgrade with Solivance Electric runs like this:
- Site assessment. We measure existing load, review your current panel, check the service entrance, and confirm what size the new service needs to be.
- Permit and utility coordination. We file the permit and coordinate the outage window with CenterPoint so your business is only de-energized for the minimum time required.
- Installation. On upgrade day, the building is taken offline, the old panel and service entrance are removed, and the new equipment is installed, labeled, and terminated cleanly.
- Inspection and re-energization. The city inspector signs off, CenterPoint reconnects, and we walk you through the new panel, labels, and any warranty documentation.
What Does a Commercial Panel Upgrade Cost?
Every building is different, but these ranges are realistic for the Houston metro area in 2026:
- 200A commercial panel swap: $3,500–$6,500 installed
- 400A service upgrade with new meter base: $8,000–$14,000
- 800A–1200A switchgear replacement: $15,000–$35,000+ depending on utility requirements
The cost depends on the length of the service run, whether the meter base is being relocated, the condition of the existing grounding and bonding, and what the utility requires for the new service.
Do Not Wait for the Panel to Fail
The most expensive panel upgrades are the ones that follow an outage, a fire, or a failed insurance inspection — because by then you are paying for the upgrade, the downtime, and the damage. If your building is showing any of the signs above, get a professional assessment before the panel forces your hand.
