Scale of Solar in Ireland 2025 Report Now Available
Solar Ireland has launched the Scale of Solar in Ireland 2025 Report to mark European Solar Day, capturing the latest trends, milestones and insights on how solar is powering Ireland’s clean energy transition.
This year’s report shows Ireland’s solar sector is delivering real climate action — and real local impact:
✅ Over 1.7 GW connected, with 2 GW in sight by September
✅ Solar met 6.5% of Ireland’s electricity demand at peak
✅ Enough clean power generated to supply over 370,000 homes each year
✅ 395,877 tonnes of CO₂ avoided, equivalent to more than 2.6 billion km of car travel
The report also highlights:
Record generation months in 2024 and 2025
Growing rooftop and community solar adoption
The critical role of battery storage and hybrid systems
How smart policy can keep Ireland on track for its 8 GW by 2030 target
Explore the key data, sector insights and community stories in this year’s report.

"Ireland’s solar sector is thriving, as the Scale of Solar report shows. This is proof of what we can achieve when government, industry and communities work together. That collaboration will be crucial as we move towards our climate goals and a more secure energy future." - Darragh O'Brien, Minister for Climate, Energy and the Environment
This report wouldn’t be possible without the dedication and collaboration of our members, partners, board and team — and everyone helping to grow Ireland’s solar story.
Together, we’re showing that solar is more than megawatts: it’s local jobs, lower bills, and a brighter, cleaner future for generations to come.
