How Much Do Solar Panels Cost in Ireland? 2026 Quote Guide

A fully installed 4 kW solar PV system on a typical 3-bed Irish home qualifies for the €1,800 SEAI grant and usually pays back in 5–7 years. The exact price depends on roof access, scaffolding needs, inverter type, panel brand and whether you add a battery — which is why we provide a fixed, no-obligation quote after a free site survey.

What affects the quote

• System size (kWp) and number of panels
• Roof type, pitch and whether scaffolding is needed
• Inverter type (string, hybrid, microinverters)
• Panel brand and warranty tier
• Battery capacity and brand
• Cable run, board upgrade or EV charger added at the same time

Add a battery

Battery price depends on capacity (5 kWh, 10 kWh, etc.), brand and whether it's paired with new solar or retrofitted to an existing system. We size and quote a fixed price after reviewing your ESB bill and existing inverter.

What's included in a quote?

A proper Irish solar quote includes the panels, hybrid or string inverter, mounting rails, DC and AC cabling, isolators, monitoring app, scaffolding, electrical certification, SEAI BER inspection support and the NC6/NC7 grid connection paperwork. Be wary of quotes that look too cheap — they usually exclude scaffolding, certification or use entry-tier panels.

What about the SEAI grant?

The SEAI Solar PV grant is €700/kWp for the first 2 kW and €200/kWp for the next 2 kW, capped at €1,800. To claim it, the installer must be on the SEAI registered list and your home must have been built and connected to the grid before the end of 2020. The grant is deducted at source, so you only pay the net amount.

Bottom line

Get a fixed quote after a free site survey, check the panel and inverter warranties (Tier 1 panels: 25 years, hybrid inverters: 10–12 years) and make sure the price is fully inclusive. The €1,800 SEAI grant and Clean Export Guarantee payments make solar one of the best home investments in Ireland.
