The Funded Solar energy solution from Kingspan ESB is expected to deliver energy savings of £320m across Northern Ireland in the next 25 years.

Customers have an option to sign up to a new PV energy generation product that the JV says will generate cheaper, renewable energy without the investment normally needed in the capital outlay, installation or maintenance of a PV system.

Kingspan ESB will design, install and maintain the solar PV system, which is guaranteed for 25 years including free lifetime system performance, monitoring and maintenance.

The JV said the average medium-sized business in Northern Ireland, consuming 400MWh of energy per year, would see a 10% reduction in their electricity bill, equivalent to £5800 annually.

The saving would increase to £17,000 a year for the average large energy user, consuming 8000MWh annually.

Kingspan Insulated Panels managing director Gilbert McCarthy said: "We are confident this partnership with ESB will now play a significant role in Northern Ireland reaching its target of 40% renewable generation by 2020.

"By removing the financial barrier to the adoption of rooftop solar PV, our fully funded solution strengthens the case for businesses to benefit from green, lower cost power and improve their long-term competitiveness."
