For most Tega Cay homeowners, a smart electrical panel upgrade usually costs $4,500 to $10,000+ installed.
A simpler standard 200-amp panel upgrade is often closer to $2,500 to $5,000, while a true smart panel setup can cost more because of the equipment, circuit controls, monitoring features, permits, utility coordination, and labor. Current 2026 cost guides place standard 100-to-200 amp upgrades around $1,800–$3,500, with full service upgrades often $2,500–$5,000 before smart panel add-ons.
First, what do you mean by “smart panel”?
This matters because “smart panel” can mean three different things:
| Upgrade type | Typical cost | What it does |
| Energy monitor only | $500–$1,500+ | Tracks usage, usually does not control circuits |
| Smart load management add-on | $1,500–$4,500+ | Helps manage EV chargers, HVAC, appliances, solar, or battery loads |
| Full smart panel replacement | $4,500–$10,000+ | Replaces the panel and gives app-based circuit monitoring/control |
Some systems are designed to avoid a full utility service upgrade by managing loads more intelligently. Savant, for example, announced a smart load-management system starting around $1,500 before professional installation.
Why Tega Cay homes may cost more
Smart panel work gets more expensive when the home needs:
- A 100-amp to 200-amp service upgrade
- Meter base replacement
- Utility disconnect/reconnect coordination
- New grounding and bonding corrections
- Space added for EV chargers, heat pumps, or generators
- Panel relocation
- Outdoor-rated equipment
- Permit and inspection work
Tega Cay handles permitting and inspections through its city permitting process, so this is not the kind of project that should be treated like a simple device swap.
When is a smart panel worth it?
A smart panel may make sense if you are planning:
- EV charger installation
- Solar or battery backup
- Generator backup
- Heat pump or major HVAC upgrade
- Home electrification
- Better circuit-level energy tracking
- Load management without automatically jumping to a larger service
It is usually not worth it if you simply need a safe, standard panel replacement and do not care about app control or energy management.
What should a good estimate include?
A good electrician should explain:
- Whether you need a panel replacement or full service upgrade
- Whether your home has 100-amp, 150-amp, or 200-amp service
- What smart features are actually included
- Permit and inspection costs
- Utility coordination
- Breaker compatibility
- Surge protection options
- EV, generator, solar, or battery readiness
- What happens if you choose a standard panel instead
The goal is not to buy the most advanced panel. The goal is to make sure your home has the electrical capacity, safety, and control you actually need.
