Certa has agreed its first two deals under a €50 million plan to invest in solar energy projects over the next five years.
The fuel supplier company, which is part of the DCC group, said the initiative is aimed at delivering 50 megawatts (MW) of solar power to 100 large Irish businesses, which is enough to power 12,000 homes.
Certa's new Solar as a Service (SaaS) offering is being provided through solar and renewable energy company Alternative Energy Ireland (AEI), which Certa acquired in 2023.
It said the service will enable large Irish businesses to harness the power of rooftop and ground mounted Solar Photovoltaic (PV) panels to "significantly reduce their energy costs and carbon emissions without any capital investment or maintenance costs".
AEI will manage the installation and ongoing maintenance of each of the solar energy projects "to ensure they achieve 90% of their expected energy output annually".
Wewise, a sister company within the DCC group, will provide tailored financing arrangements for the projects "without upfront costs".
Jabil, which is in Bray in Co Wicklow, has become the first company to avail of the new service in a deal worth €1.2 million.
The company specialises in the design, development, and commercial scale up of complex and innovative healthcare products for pharmaceutical, medical device and diagnostic companies.
Jabil is installing 3,000 rooftop solar PV panels.
Certa said the 1.5 megawatt (MW) solar system will generate 1.3 million kilowatt (kWh) units of renewable solar power annually for the next 25 years and will reduce carbon emissions by 360 tonnes per year.
A deal has also been reached with Lindab, a supplier of energy-efficient ventilation systems, building solutions and accessories, valued at €200,000.
The company is installing 400 rooftop solar PV panels across its three sites in Dublin.
Certa said the 178kWh solar system will generate 165,000kWh units of solar power annually and will reduce carbon emissions by 44 tonnes each year.
