Thinking about upgrading your electrical panel but unsure of the cost? Whether you're renovating, adding new appliances, or installing solar panels, knowing what to budget is essential. 

A main panel upgrade ensures your home can safely manage modern power demands while meeting current regulations. The cost can vary depending on factors like panel size, installation complexity, and labour rates. Without proper planning, expenses can quickly add up. 

In this blog, we’ll explore how much does a main panel upgrade cost in Ireland and give you clear insight into what to expect and how to make the right decision for your home.

Let’s start!

What Does a Main Panel Upgrade Involve?

If you're thinking of installing solar panels, your home's existing electrical setup might not be up to the task. A main panel upgrade ensures your system can safely manage the energy generated by your new solar installation. 

Since the solar system connects directly to the main panel, it's essential that it can handle the additional power flow. In many cases, upgrading the panel is necessary for a safe and reliable connection. Around 15% of homeowners find this step is needed before going solar.

Why Might Your Main Panel Need an Upgrade?

Your home’s main electrical panel is at the centre of how power is distributed. When adding solar or increasing your home’s electrical usage, it’s essential to ensure your panel is strong enough to handle the load and meets modern safety codes.

Higher Electrical Load from Solar Systems

When you install a solar system, it adds extra current to your home's electrical flow. If your panel can't cope with the added energy, it could become overloaded. An upgrade ensures your system runs safely and efficiently.

Outdated Amperage Ratings

Most homes have panels rated between 100A and 200A, but newer homes may need more. The more appliances and devices you use, the higher the demand on your panel. A low-rated panel limits what you can run at the same time and may fail safety checks.

Non-Compliant or Recalled Panels

Older electrical panels may not meet today’s safety standards. Some may have been recalled or fail to meet current building codes. Upgrading to a modern, compliant panel reduces fire risk and ensures smoother approval for installations like solar systems.

Safety and Permit Requirements

To install solar or make major changes, your local authority may require that your panel meets the latest codes. Panels not up to standard can pose a serious safety hazard. This can also impact how much a main panel upgrade costs? if additional inspections or rewiring are needed.

What Affects the Cost of a Main Panel Upgrade?

The cost of a main panel upgrade in Ireland typically ranges between €500 and €1,500 or more, depending on various key factors. One major influence is the size and capacity of the new panel, higher amperage panels generally cost more. 

The complexity of the installation also affects the final price, especially if the location is difficult to access or if significant rewiring is needed. Labour charges vary by region and electrician, adding to overall expenses. 

If your current setup is outdated or not up to code, additional upgrades may be necessary, raising the cost. Always request a detailed quote to know exactly how much a main panel upgrade costs.
