Are Solar Panels Worth It in Ireland in 2026?

Solar panels in Ireland are now one of the best home investments available — the combination of high electricity prices, the €1,800 SEAI grant and the Clean Export Guarantee (CEG) payment for exported power means typical payback is 5–7 years.

What does a solar PV system cost in 2026?

A standard 4 kW system for a 3-bed semi costs about €8,500 fully installed, or €6,700 after the SEAI grant. Larger 6 kW systems for detached homes come in around €9,700 after grant.

How much will you save?

• Cut your electricity bill by 50–70%
• Earn 18–24c per kWh exported back to the grid
• Add a home battery to use solar at night
• Increase your home's BER and resale value

Bottom line

For most Irish homes with south, east or west facing roofs, solar PV is absolutely worth it in 2026. The payback period is shorter than it has ever been and panels are warrantied for 25 years — meaning 18+ years of essentially free electricity after payback.
