National Average
$1,500 – $4,000
per project
Upgrading to a 200-amp electrical panel costs $1,500–$4,000 installed — a requirement for solar, EVs, and modern appliances.
Overview
Upgrading your electrical panel to 200 amps costs $1,500–$4,000 installed, depending on your current panel capacity, local permit requirements, and whether the utility needs to upgrade the service entrance. A 200-amp panel is the minimum recommended for modern homes with solar, EV chargers, heat pumps, or electric appliances. Older 100-amp panels are inadequate for today's energy needs.
Cost by Scope
100A to 200A upgrade
Standard residential upgrade. Handles solar, EVs, and modern appliances.
$1,500–$3,000
200A to 400A upgrade
For large homes with multiple EVs, large solar arrays, or whole-home electrification.
$2,500–$5,000
Full rewire + new panel
Older homes with knob-and-tube or aluminum wiring needing full electrical update.
$8,000–$20,000
What Affects the Cost
High
Current panel size
Upgrading from 100A to 200A is most common. 60A or fuse box replacements cost more due to additional work.
High
Utility service entrance
If the utility meter and service entrance also need upgrading, add $500–$2,000 and utility coordination time.
Low
Panel brand
Siemens, Square D, and Eaton are top-rated. Avoid Federal Pacific and Zinsco panels (safety concerns).
Medium
Number of circuits
Adding circuits for EV chargers, solar, or appliances adds $150–$300 per new circuit.
Low
Local permit fees
Electrical permits run $75–$300 and include an inspection — never skip this step.
Medium
Licensed electrician
This work requires a licensed master or journeyman electrician. Do not attempt DIY.

Frequently Asked Questions
Do I need a permit for an electrical panel upgrade?
Yes, always. A permit ensures your work is inspected and meets code. Unpermitted electrical work can void your homeowner's insurance and cause problems when selling.
How long does a panel upgrade take?
A straightforward 200-amp upgrade takes 4–8 hours. More complex work involving service entrance upgrades may require utility coordination and take 1–2 days.
Is a 200-amp panel required for solar?
Not always required, but strongly recommended. Solar systems add to your panel's load; most solar installers require at least 150–200 amp service.
What are signs I need a panel upgrade?
Frequent tripped breakers, flickering lights when appliances start, a panel that's hot to the touch, or a home older than 40 years with original wiring are all signs.
Does an electrical panel upgrade increase home value?
Yes — appraisers typically add $1,500–$3,000 in value for a modern 200-amp panel, and it's often required by buyers' lenders when purchasing older homes.
