About this service

Panel Upgrades for Houston Area Buildings

An electrical panel is the meter-to-load junction for every circuit in the building. When the main breaker is undersized, the bus is pitted, or the bonding is wrong at the service entrance, the symptoms show up everywhere — lights dimming when an RTU kicks, breakers tripping at half load, a panel cover that is warm to the touch at 3 pm on a hot day. Solivance Electric replaces commercial and high-end residential panels across Houston, Cypress, Katy, and Memorial — 100A, 200A, 400A, and 3-phase 208/480 services. Every swap includes load calcs against actual metered demand, meter base and main breaker replacement, feeder upsizing when the run is marginal, legible circuit labeling, and a final walk with the inspector before the seal goes on.

On day two, the panel upgrade was completely finished exactly when Solivance Electric said it would be. They answered every question and addressed my concerns directly. The quality of the work and the customer service was excellent.

How it works

01
Site walk and load calc

We open the existing panel, check the bus, read the meter history, and pull a load calc against actual demand — not a rule-of-thumb number.

02
Fixed-fee quote

Itemized scope: gear list, permit fee, CenterPoint coordination, downtime window, and final number. Signed before any material is ordered.

03
Permit, cut-over, install

Harris County or City of Houston permit filed. CenterPoint disconnect scheduled. Panel swapped, feeders upsized where needed, every breaker labeled.

Pricing

A 200A commercial panel upgrade typically runs $2,500–$8,500 installed. 400A services and 3-phase 208/480 switchgear replacements run $6,000–$18,000, with larger switchgear builds pushing past $25,000. Final pricing depends on meter location, whether the service entrance needs relocation, feeder length, and how much of the CenterPoint work is ours versus theirs. Every number is a fixed-fee quote after a free site walk — no ballpark over the phone, no surprise changes mid-job.

Timeline

Most 200A commercial upgrades are on and re-energized inside 1–2 business days, with the building de-energized for only a portion of that window. 400A and 3-phase switchgear replacements typically run 3–5 working days because of utility coordination, gear lead time, and longer feeder pulls. Permit pull and equipment delivery sit ahead of that on the calendar.

Code & permits

Commercial panel upgrades in Greater Houston are typically pulled under the 2023 National Electrical Code as adopted by the Texas Department of Licensing and Regulation. Service-entrance grounding falls under NEC 250, working clearances under NEC 110.26, and the bonding jumpers in the meter and main are inspected for visibility. CenterPoint Energy handles the service-drop cut-over inside their territory — we coordinate the outage window so your tenants see the shortest possible disruption.

Frequently Asked Questions

How much does a commercial panel upgrade cost in Houston?+
A 200A commercial panel upgrade typically runs $2,500–$8,500 installed. 400A services and 3-phase 208/480 switchgear replacements run $6,000–$18,000, with larger switchgear builds pushing past $25,000. Final pricing depends on meter location, whether the service entrance needs relocation, feeder length, and how much of the CenterPoint work is ours versus theirs. Every number is a fixed-fee quote after a free site walk — no ballpark over the phone, no surprise changes mid-job.
How long does a commercial panel upgrade take?+
Most 200A commercial upgrades are on and re-energized inside 1–2 business days, with the building de-energized for only a portion of that window. 400A and 3-phase switchgear replacements typically run 3–5 working days because of utility coordination, gear lead time, and longer feeder pulls. Permit pull and equipment delivery sit ahead of that on the calendar.
What are the warning signs my commercial panel needs an upgrade?+
Lights dimming when an RTU or compressor starts, breakers tripping at normal load, a panel cover that is warm to the touch, burning-plastic smell near the gear, visible scorching on bus or breakers, or a building running modern HVAC and equipment off a 100A service. Any one of those is a call.
Do you handle 3-phase commercial service upgrades?+
Yes. 208Y/120 for multi-tenant buildings, 480/277 for industrial loads and high-bay lighting. Gear selection (main breaker vs main lug, NEMA 3R vs indoor), fault-current rating, and SCCR matching are all part of the quote.
Will you coordinate with CenterPoint for the meter cut-over?+
Every time. We file the service request, schedule the disconnect/reconnect window, meet the CenterPoint tech on site, and hand back a legible meter base with a fresh seal.
How long is the building de-energized during a panel swap?+
Most 200A single-phase cut-overs are 2–6 hours of no-power time, sequenced around your occupancy. 400A and 3-phase swaps can push to a full day. We plan the outage window in the quote, not on the day of.
Do I need a permit to replace my panel in Houston?+
Yes — any service-entrance work requires a permit and an electrical inspection, whether the jurisdiction is the City of Houston, unincorporated Harris County, or one of the Memorial villages. We pull it, file it, and meet the inspector.
Do you replace meter bases and masts at the same time as the panel?+
Often — if the meter base is undersized, cracked, or wrong rating for the new service, it gets replaced in the same scope. Same for mast and weatherhead on an overhead service. It is cleaner to do both while the drop is already down.
