This data comes from Kilowatt.ie, an online tool that tracks small-scale solar energy in Ireland. The platform was founded by Dominic Ó Gallachóir, who attributed the record output to a combination of factors. “With above-average sunshine levels last month and a strong pipeline of installations going live, April 2025 marks a significant step forward for domestic and small-business solar in Ireland,” Ó Gallachóir commented at the start of May. He added that consumers would notice the impact on their energy bills.
Ireland’s small-scale solar capacity has doubled over the past two years, with more than 132,000 installations in place, totaling 560 MW of capacity. The government has actively supported this growth by offering various incentives for solar energy adoption. These include grants like the Solar for Schools scheme, commercial solar PV grants, and retrofitting programs for residential solar installations.
Kilowatt.ie, which launched its solar tracker tool in March, reported that as of that month, over 120,000 small-scale solar systems were installed across Ireland, contributing a combined 500 MW of capacity. The growth in small-scale solar is seen as a positive step toward meeting Ireland’s renewable energy goals.
Overall, Ireland’s small-scale solar sector has experienced significant growth, driven by favorable weather conditions, strong government incentives, and increasing consumer adoption. As the number of installations continues to rise, solar energy is expected to play a larger role in meeting Ireland’s energy needs, with benefits extending to both households and businesses.
