Should You Upgrade Your Electrical Panel Before Installing Solar or an EV Charger?

Thinking of Installing Solar Panels or an EV Charger in Indianapolis? Your Electrical Panel Might Not Be Ready

If you’re planning to install solar panels or a Level 2 electric vehicle (EV) charger at your Indianapolis home, there’s one critical step many homeowners overlook: checking the capacity of your electrical panel. Without a modern electrical panel, your home may not be equipped to handle the extra load required by these energy-efficient upgrades.

Let’s break down why your electrical panel matters, when to consider an upgrade, and how an Indianapolis electrician can help make your project safe, efficient, and future-proof.

Why Your Electrical Panel Matters

Your electrical panel—sometimes called a breaker box—is the hub that distributes electricity throughout your home. It determines how much power your home can safely use at once.

Older homes in Indianapolis, especially those built before the 1990s, often have panels rated at 60 to 100 amps. However, today’s electrical demands—including high-efficiency HVAC systems, electric vehicles, and solar power systems—often require a 200-amp panel or larger.

If your panel is outdated or undersized, installing a Level 2 EV charger or solar inverter may trip your breakers, cause flickering lights, or even present fire risks.

Signs You May Need an Electrical Panel Upgrade

If any of the following apply, it’s a good time to schedule a professional inspection:

  • Your panel is more than 25 years old
  • You still have a fuse box or aluminum wiring.
  • The panel lacks room for additional breakers
  • Breakers trip regularly, or you notice overheating.
  • You’re upgrading appliances or planning a home addition.

Even if your system seems “fine,” adding an EV charger or solar setup can tip the balance—and Indianapolis electrical codes require homes to be up to current standards.

What Happens During a Panel Upgrade?

Upgrading your panel is more than a quick swap. Here’s what to expect:

  1. Assessment of Load Requirements: A licensed Indianapolis electrician will calculate the total electrical demand of your home and determine the appropriate panel size.
  2. Permit and Code Compliance: Upgrades require city permits and inspections to ensure safety and code compliance. A professional will handle all of this for you.
  3. Service Disconnect & Replacement: Power may be temporarily shut off while your old panel is replaced with a modern one.
  4. Inspection & Restoration: Once installed, the panel is inspected by the city and reconnected to your utility service.

This process usually takes one day, although complex jobs or weather delays can stretch the timeline.

Why Upgrade Before Solar or EV Installation?

It’s far more efficient—and less expensive—to upgrade your panel before installing an EV charger or solar system than to do it afterward. Here’s why:

  • Avoid Delays: Utility companies won’t approve new connections if your system doesn’t meet current capacity standards.
  • Prevent Double Labor: Installing a charger now and upgrading later means rewiring the same circuits twice.
  • Maximize Safety: Overloaded panels can create fire hazards and invalidate warranties on your solar or EV equipment.

Bonus tip: Upgrading now gives you flexibility to add future tech, like battery storage or a second EV.

Cost of a Panel Upgrade in Indianapolis

In Indianapolis, the average cost of a 200-amp panel upgrade ranges from $1,800 to $3,500, depending on:

  • Your current panel size and age
  • The condition of your wiring and meter
  • Whether a service mast or grounding upgrade is needed
  • Permit fees and inspection requirements

While this is an investment, it adds safety, convenience, and resale value to your home.
