Frequently asked questions
What was Ireland's cumulative PV capacity by the end of 2025?
Ireland’s cumulative PV capacity reached 3,026 MWdc by the end of 2025. This figure reflects the country’s ambitious growth in the solar photovoltaic market, driven by increasing installations across residential, commercial & industrial (C&I), and utility segments. The expansion highlights Ireland’s commitment to renewable energy integration.
Which segment was the primary driver of newly added PV installations in Ireland during 2025?
The utility segment was the primary driver of newly added PV installations in Ireland during 2025, accounting for 56.6% of the total. This significant contribution underscores the country’s focus on large-scale solar projects to expand its renewable energy infrastructure. The residential segment followed, contributing 35.8% of new installations.
What share of newly added PV installations did the residential segment contribute in Ireland during 2025?
The residential segment contributed 35.8% of newly added PV installations in Ireland during 2025. While the utility segment led new capacity additions, the substantial contribution from residential installations indicates a growing adoption of rooftop solar among homeowners. This diversification across segments supports Ireland’s overall PV market expansion.
When did PV installations in Ireland's Commercial & Industrial (C&I) and utility segments begin to rise?
PV installations in Ireland’s Commercial & Industrial (C&I) and utility segments began to rise since 2020. Prior to this period, the Irish PV market was primarily limited to residential rooftop installations.
