How much do solar panels cost in Ireland?

A typical 10-panel (4.4 kWp) system costs €8,300–€9,000 installed, or €6,500–€7,200 after the €1,800 SEAI grant. Smaller 6-panel systems start from €4,980 after the grant and large 22-panel systems run to €15,200.

How much does a single solar panel cost?

Installers price whole systems, not single panels. On a 10-panel system the installed price works out at roughly €830–€900 per panel before the grant, and that figure includes the inverter, mounting, cabling and labour.

What are the cheapest solar panels in Ireland?

The lowest-priced option is a 6-panel (2.6 kWp) system at €4,980–€5,780 after the grant. It costs more per panel than a larger system because the inverter, scaffolding and labour are spread over fewer panels, so the cheapest system is rarely the best value.

Is there VAT on solar panels in Ireland?

No. Solar panels supplied and installed on a private home have been zero-rated for VAT since May 2023, so residential quotes carry 0% VAT.

How much is the SEAI solar grant?

€700 per kWp for the first 2 kWp and €200 per kWp for the next 2 kWp, up to a maximum of €1,800. The home must have been built and occupied before 2025.

What changes the price

System size. Bigger systems cost more in total but less per panel: a 20-panel system is about €700 per panel against €1,080 for a 6-panel system.
A battery. Adding one at install time costs less than adding it later. See battery prices.
The grant. The SEAI grant is capped at €1,800, which every system of 4 kWp or more reaches.
Your roof. Slate or tile type, roof height, split arrays and shading all affect the labour and equipment a quote includes.
