Solar energy company Activ8 Solar Energies has commenced work on what is expected to become Ireland's largest rooftop solar installation, a 6MW system spanning 3.88 hectares of rooftop space across Mannok's manufacturing facilities in Co. Cavan, as reported by Irish Building Magazine .

The installation will comprise approximately 10,000 solar panels and, once fully energised, will supply a significant portion of Mannok's electricity demand while avoiding an estimated 792 tonnes of carbon emissions each year. The footprint of the completed project is equivalent to almost three GAA pitches.

Mannok is one of Ireland and the UK's most diverse manufacturers of construction products and plastic packaging. The project is structured as a fully funded Power Purchase Agreement with SSE Airtricity, allowing Mannok to access onsite renewable electricity generation without upfront capital investment, paying a reduced fixed rate for electricity generated for the duration of the agreement.

Ciaran Marron, CEO of Activ8 Solar Energies, said: "This project marks a major milestone for both Activ8 and Mannok. The commencement of Ireland's largest rooftop solar installation demonstrates what can be achieved when ambitious businesses invest in renewable energy at scale. By investing in this significant solar project, Mannok is taking a meaningful step towards reducing emissions, strengthening energy resilience and helping to drive transition to a lower-carbon future."

Dara O'Reilly, CEO of Mannok, said: "Sustainability is an increasingly important part of how we operate as a business. This project represents another significant step in that journey. Once complete, the installation will enable us to generate renewable electricity onsite, helping us to reduce our carbon footprint while enhancing the resilience of our manufacturing operations. We are proud to partner with Activ8 and SSE Airtricity on a project that demonstrates our commitment to innovation and continuous improvement."

Stephen Gallagher, managing director of SSE Airtricity, said: "By removing the need for upfront capital investment, businesses can access renewable energy solutions with immediate benefits and predictable costs. We are delighted to partner with Mannok on this landmark development."

The project is supported through Activ8 and SSE Airtricity's jointly funded solar initiative, valued at up to €200 million, announced earlier this year. The development also marks Activ8 Solar Energies' 20th year in business.
