Panel Cost by Size (Amp Levels)
100 Amp vs 200 Amp vs 400 Amp: Which One Do You Need?
Amp size is how much power your home can use at once. Think of it like a speed limit for electricity. Old homes from before 2000 have 100-amp panels. This is too small now. A 200-amp panel is what new homes need (for EV chargers and heat pumps). A 400-amp panel is rarely needed for houses.
Here are the costs for each type:
| Type of Work | What You Do | Cost | When You Need It |
|---|---|---|---|
| Same Size Swap | 100A → 100A (or 200A → 200A) | $1,500 – $2,500 | Old panel that’s broken |
| Modern Upgrade | 100A → 200A | $2,000 – $4,000 | EV charger, heat pump, solar |
| Big Upgrade | 200A → 400A (or new 400A) | $4,000 – $8,000+ | Multiple EVs, large house |
| Extra Panel | Add second 100A–200A panel | $400 – $1,750 | Garage, shed, or EV charging zone |
What It Costs: 100A → 200A Upgrade
Panel Box: $400 – $1,000
This is the new metal box and breaker switches inside. The price changes based on the brand (Square D, Siemens, GE) and your local rules.
Work (Labor): $1,500 – $2,500
This is what the electrician charges. It’s usually $50–$150 per hour × 20–30 hours of work. Work includes: turning off power, removing old panel, putting in new panel, adding breakers, and testing. Price changes based on how easy the panel is to reach.
Permits: $150 – $500
Your city needs to approve the work. They charge a fee. Sometimes this is included in the total price. Ask for a clear list.
Why 100A → 200A is most popular: New homes with EV chargers (40–50 amps), heat pumps (15–25 amps), and electric stoves (40+ amps) need the extra power. The 200-amp panel is now the standard.
Hidden Costs That Surprise You
Most electricians only quote for the panel swap. They don’t tell you about extra work that adds $500–$3,000. Here are four types of hidden costs:
1. Power Company Charges
Your power company must turn off and turn back on your power. This costs money and is usually not in the electrician’s quote.
⚠️ Power Company Charges
- Turn off and turn back on: $200 – $800
- New power line: $700 – $1,500 (if upgrading from 100A to 200A)
- New meter: $100 – $300
- Power pole work: Extra $500–$1,000+ if lines need to move
What to do: Call your power company before asking electricians for quotes. Ask: “How much to upgrade from 100A to 200A at my address?”
2. Safety Code Rules That Are Required
When you replace a panel, the law requires safety upgrades. These are not “extras”—they are required by law. Electricians often hide these in small print.
Ground Rods & Water Pipe Bonding: $100 – $500
The law says you need two copper rods driven 8 feet into the ground. You also need to connect water pipes and gas pipes. Old homes don’t have this. The electrician digs holes, drives rods, and connects wires.
Safety Breakers: $50 – $300
New rules require special breakers that catch electrical problems. Old panels may need new breakers beyond the main swap.
Panel Connection & Main Breaker: $200 – $400
The new panel must be properly connected to the ground system. The main breaker may also need to be replaced.
3. Wall Repair Costs
Electricians drill holes and cut walls. They do NOT fix the walls. You pay for that.
Wall Patching: $1.50 – $3.00 per square foot
A worker comes in to fix holes, sand, and paint. For 2–3 holes, expect $300–$800. If the panel moves to a new spot, the old hole needs full wall repair.
Paint & Touch-Up: $50 – $200
If you see new pipes on your walls, you’ll want them painted to match. Electricians don’t do this.
4. Digging for Underground Lines
If your power lines are above ground and you want them below ground, digging costs a lot.
⚠️ Underground Line Costs
- Digging + machine rental: $600 – $2,100 (50–200 feet)
- Pipes and wire: $1.50 – $5.00 per foot
- Power company work: Often $500–$1,500
Reality check: Unless your power company says you MUST go underground, stay with above-ground lines. Underground is a choice, not a need. Ask your power company if it’s required.
Signs You Need to Upgrade (or Not)
5 Bad Signs That Your Panel Needs to Go
Before you spend $2,500–$5,000, make sure you really need an upgrade. Here are five major warning signs:
- Hot Panel Door: The panel should never feel warm. If it does, there’s a problem. This is dangerous.
- Burning Plastic Smell: If you smell burning plastic near the panel, turn off the main breaker RIGHT NOW. Call an electrician. This is serious.
- Lights Flicker When Appliances Turn On: Some flicker is normal. But if lights flicker a lot when your fridge or AC turns on, your panel is too weak.
- Rust or Damage Inside the Box: Open the panel door (don’t touch wires) and look for rust, white spots, or green spots on breakers. These mean water got inside.
- Old, Dangerous Panel Brands:
- Federal Pacific Electric (FPE) — Known to fail. Upgrade now.
- Zinsco — Breakers rust and fail. Upgrade now.
- Pushmatic — Very old. No parts left. Upgrade.
New Appliances: When You MUST Upgrade
Even if your old panel works okay, new appliances need more power. Here’s what happens:
EV Charger (50A) + Heat Pump (20A) + Electric Stove (50A) = YOU NEED 200A
EV Charger (Level 2): Uses 30–50 amps. A 100-amp panel can handle it alone. But add other big appliances and you’re in trouble.
Heat Pump HVAC: Uses 15–25 amps. When the AC turns on with the EV charger, a 100-amp panel gets overloaded.
Solar System: Even if you make power, the inverter needs lots of capacity. Most solar companies say you need at least 200 amps.
The truth: If you’re planning to add an EV charger, heat pump, or solar, assume you need a 100A → 200A upgrade. Plan for it now. Don’t wait until the installer tells you later.
Get Money Back: 2026 Rebates & Tax Credits
Federal Tax Credit (30% Off)
The US government gives you money back when you upgrade your panel with a new energy-smart appliance.
✓ How the Tax Credit Works
- You get back: 30% of your panel cost
- Max credit: $600
- You need: To also install a heat pump, solar, electric stove, or other green appliance
- How to claim: File with your taxes (Form 5695)
Example: Your panel costs $3,000 and you add a heat pump ($8,000). You get 30% of the panel cost = $600 tax credit. The heat pump gets a separate $2,000–$3,500 credit.
State Rebates (Up to $4,000)
Some states give direct money (not tax credits) to lower-income families who upgrade their panels.
✓ State Rebate Program (HEEHRA)
- Rebate: Up to $4,000 for panel upgrades
- Who qualifies: Lower-to-middle income families
- Status: Available now in some states; rolling out to more
- Check if you qualify: Visit ENERGY.gov/heehra or call your state energy office
- Type of money: Direct payment (not a tax credit)
Stack Both: You can use BOTH the federal tax credit AND the state rebate. Example: $3,000 panel – $600 tax credit – $2,000 state rebate = $400 you pay.

Three Must-Ask Questions
Question 1: Who contacts the power company?
“Will you call my power company for the turn-off and turn-on, or do I? What will they charge?” — This can add $200–$1,500.
Question 2: Are permits included?
“Does your labor price include getting permits and city inspections, or are those extra?” — Permits add $300–$500 if not included.
Question 3: Do I really need 400 amps?
“For my house size and my EV + heat pump plan, what’s the minimum amps I need?” — Don’t let them push an expensive 400-amp upgrade you don’t need.
Red Flag: The 400-Amp Scam
If a contractor pushes a 400-amp upgrade without checking your actual electrical load, they’re padding the bill. Most houses (under 5,000 sq ft) with 1–2 EVs need only 200 amps. Ask for a written load calculation if they say 400 amps.
Questions & Answers
Can I do this myself (DIY)?
No. You need a licensed electrician. DIY panel work is illegal, voids your insurance, and is deadly. The panel has lethal voltage. Don’t touch it.
How long does it take?
The work takes 4–8 hours. But the whole project (power off, permits, inspection, power on) takes 4–8 weeks. Plan to be without power for part of a day.
Does an upgrade raise my home value?
Not directly. But a modern 200-amp panel is now expected. Without it, buyers offer less. The upgrade stops them from reducing the price. It’s protective, not additive.
Do I need an upgrade for solar?
Yes, almost always. Solar installers require a 200-amp panel minimum. Ask them to include the panel cost in the total quote.
Subpanel vs. full replacement: What’s the difference?
A subpanel ($400–$1,750) adds power in one spot (garage, shed). A full replacement ($1,500–$5,500) upgrades your main panel. For whole-home electrification, you need a full replacement.
Are there payment plans?
Yes. Some power companies offer 0% loans for upgrades. Ask your power company. Also ask contractors about PACE financing (pay through your property tax bill).
