In just two years, Ireland''s installed solar capacity has increased by 159.8%. When we launched our first Scale of Solar report in 2023, solar energy in Ireland was still emerging. But today, it''s undeniable:
Dublin, 13 November 2025 – Ireland celebrated a landmark moment in its clean energy transition, with national solar capacity surpassing 2 GW for the first time. This milestone reflects the remarkable
But don''t worry, we can give you some seriously solid estimates. On average, a well-installed 1-kilowatt-peak (kWp) solar PV system in Ireland will churn out anywhere between 900 kWh and 1,100 kWh of
Ireland adds 1 GW of solar in 2025 Ireland reached 2,345 MW of installed solar capacity by December 2025, more than tripling installed capacity since 2023, according to Solar Ireland data.
A typical 4 kW solar system in Ireland generates around 3,400-4,400 kWh of electricity per year, according to the Sustainable Energy Authority of Ireland (SEAI).
