How much do solar panels cost in Ireland?

Solar panels are a solid investment. They pay for themselves over time and cut your energy bills in the process. That said, it's natural to wonder what you're actually signing up for before installing a system for the first time.

How much does a solar panel system cost?

Solar panel prices in Ireland have been falling for years, thanks to better technology, higher production volumes, and economies of scale. Most homeowners pay somewhere between €6,000 and €18,000 for a full installation, depending on their setup.

A few things drive that price up or down:

Panel type and efficiency. Monocrystalline, polycrystalline, and thin-film panels all perform differently. The more efficient ones cost more upfront, but often pay off better over the long run.

Installation costs. Labour, scaffolding, and any extra equipment all add to the total bill.

Government incentives. Grants and supports can take a meaningful chunk off the upfront cost, which is a big part of why solar has become accessible to far more households.

System size. A bigger system costs more to install, but it also generates more electricity, so the cost per kWh often works out similarly.

Is it expensive to get solar panels?

The upfront cost is a genuine lump sum, no way around that. But the value shows up over time. Most systems pay for themselves through energy savings, and once they have, any extra power you sell back to the grid is pure profit.

Solar panels typically last 25 to 30 years, and most Irish homeowners recoup their installation cost within about 7 years through lower energy bills.

Get support through the Solar PV Grant

The Sustainable Energy Authority of Ireland (SEAI) offers a grant to homeowners installing solar PV panels.

The grant is capped at €1,800, no matter how large your system is. Most homes hit that cap once they go above 4 kWp.

You'll need to apply for the grant and get approval before any work starts or materials are purchased, so check you meet the criteria first.

Examples of prices

A solar system is made up of individual panels, arranged into what's called an array. The most common setup for Irish homes is an 8-panel, 3.2 kWp system, though larger households or higher energy users often go bigger.

These are average figures. Your actual price will depend on your property, the panels you choose, and a few other factors. The easiest way to get a clear picture is to fill out the form and hear from solar suppliers who can talk you through what works for your home and what it's likely to cost.

Find the right solution for you

The only way to know exactly what a system will cost is to get a personal quote for your own home. Talking it through with a supplier is the best way to understand how solar would actually work for you.

At Solarpanels.ie, you can request quotes from several solar suppliers at once. Fill in the short form, compare what comes back, and pick whichever option suits you best, whether that's the equipment, the supplier, or simply the price.
