Ireland's Solar Power Surges 160% Since 2023, Meeting 21.1% Peak Demand in May 2025
Ireland's solar power has surged, increasing 160% since 2023 and meeting 21.1% of peak demand in May 2025. This growth, driven by government support, corporate demand, and technological advances, now powers over 370,000 homes and significantly reduces carbon emissions, making solar a vital part of the nation's energy mix.
Ireland's solar power output increased by 49% in the last year and 160% since 2023, now supplying over 370,000 homes and preventing 395,000 tonnes of carbon emissions annually. In May 2025, solar met a record 21.1% of peak electricity demand. This growth, once surprising, aligns with global trends and makes solar a significant part of Ireland's renewable energy mix, complementing wind capacity.
Key drivers for this expansion include government support through the Renewable Energy Support Scheme (RESS), which provided fixed income streams for solar projects, attracting investment and bank funding. The emergence of strong multinational corporate power purchasers seeking green energy has also fueled demand. Technological advancements mean modern solar panels generate power from daylight, not just direct sunlight.
Additionally, falling costs, improved technology, and changing consumer attitudes, supported by government policies like rooftop grants and zero VAT on residential installations, have boosted adoption. Ireland's robust legal and regulatory framework further assures investors. Solar power, including rooftop installations, enhances the energy sector's resilience and offers consumers direct control over costs.
